rotational grazing cons

On our farm, I like to utilize pasture-based systems for our animals that steward the land well and make my life easier. This difference could be attributed to the fact that pastures evaluated in this prior study contained a mix of warm-season and cool-season forages. Monthly average temperature, total precipitation, and average relative humidity are listed in Table 2, historical monthly averages are listed in Table 3. Warm-season grasses tend to accumulate lower WSC content than cool-season grasses due to lower fructan synthesis (Chatterton et al., 1989).

Similar to above for VC, this corresponds to a month that fell directly after poor precipitation compared with historical averages. Recommended management practices for each grazing system were followed for 27 mo including three grazing seasons. 1Analyses were performed by Dairy One DHIA Forage Testing Laboratory, Ithaca, NY. Compared with C, R had higher proportions of G and W and lower proportions of GW and O. Sharpe (2019) states that as plants mature, DE decreases slightly while CP decreases significantly, which could potentially explain why CP and DE might not correspond to plant maturity to the same degree. In the R pastures, permanent shelters, water sources, and hay feeders were located within 0.17 and 0.16 ha (2R and 3R, respectively) stress lots (i.e., dry lots, sacrifice areas, exercise lots, etc.) There were also some months where snow cover prohibited sampling (n = 12 in July, September, October, November; n = 8 in January, April, May, June, August, December; n = 4 in February, March). (2010) measured NDF during July and September. Some disadvantages of managed grazing systems include the increased need for labor, adequate fencing not only for boundary fences but also for individual paddocks, and the necessity of available water for each paddock; however, when properly implemented, managed grazing systems have innumerable benefits to whole-farm sustainability and productivity. Information provided in this brochure can help you plan to attain this goal. This was evident in our nutrient content data with the R pastures being higher in DE at the time of sampling, which was prior to the sections being grazed. However, there were no differences in supplemental hay fed or maintenance costs between the grazing systems. It can also help keep weeds out of your pastures when you are controlling the grass and making sure it is not getting overgrazed. Forage nutrient content varied between treatments, with rotationally grazed pastures having higher DE, ADF, and Ca and lower CP. The problem with rotational grazing is “moving livestock between paddocks every set number of days.” Pasture does not respond to grazing the same way throughout the growing season. Rotational grazing can result in a decrease in feed costs as grazing livestock will be harvesting their own feed, which in turn will decrease the cost … This was performed 100 times per pasture (in R, 25 times per section immediately prior to grazing bouts as noted above for MASS). Daily average temperature, precipitation, and relative humidity were also tracked using the New Jersey Climate and Weather network data website (http://www.njweather.org/data). Similar stocking rates to the present study were used; however, grazing management strategies varied between studies. The C horses were on pasture 100% of the grazing time for a total of 844 d (August 1, 2014 to November 22, 2016) and R horses were on pasture for a total of 375 and 441 d (2R and 3R, respectively). Proponents call it farming grass. (2015) and Daniel et al. Overall, the study found the opposite of our original hypothesis, with the continuously grazed horses maintaining higher BCS and percentage of body fat than the rotationally grazed horses. The qualitative binary outcome for VC and TC was analyzed with a generalized linear mixed model using SAS PROC MIXED with binomial distribution, logit link, blocking by field, and including seasonal covariate month. While grazing systems have been studied extensively for livestock on rangeland (Heady, 1961; Holechek et al., 1999), little work has been done specifically with horses in temperate pastures. Black lines indicate permanent fencing and white lines indicate temporary electric tape fencing separating rotational fields. Because cows and horses prefer grass and goats prefer bushes and small trees and each species has different parasites, cows or horses can graze the paddock just vacated by the goats. Jordan, S. A., K. R. Pond, J. C. Burns, D. T. Barnett, and P. A. Evans. 1Weather data obtained for the New Brunswick Station through the Office of the New Jersey State Climatologist website (http://climate.rutgers.edu/stateclim_v1/monthlydata and https://www.njweather.org/data). All hay offered was weighed and recorded, and totals were reported for each month of the study; however, waste hay was not collected during this time. Plumb, G. E., L. J. Krysl, M. E. Hubbert, M. A. Smith, and J. W. Waggoner. At the final measurement of the study, horse BW, BCS, and FAT were 562.8 ± 15 kg, 6.0 ± 0.16, and 18.1 ± 0.64, respectively, and were not significantly different from initial measures. Eating clovers, either by grazing or in hay, often results in excessive slobbering caused by a fungus growing on the clover when conditions are adverse. 1Grasses (G) include the grasses that were planted (KB, OG, and TF), GW include any grasses not planted, weeds (W) include any nongrass plants, and other (O; includes anything else: bare ground, rocks, litter, etc.). Aesthetics and human health benefits One of the greatest advantages to using rotational grazing is that it is a “peaceful way of farming.” This was opposite of the expected outcome and an interesting finding given the greater DE of the forage in the rotational pastures. Most previous studies have used other livestock animals, such as cattle and sheep, which have different grazing habits than horses. Months with CI gaps between treatments are different at P < 0.05. Present study values fell within this range with the NDF being around 70% at the high end and as low as 40% during the early spring months, at which time most grasses were short and actively growing, while Fleurance et al. Other (O) represents all other vegetation (living or dead), plus bare ground, rocks, litter, etc. Pasture maintenance on C fields cost $17.55 ± 3.14 and on R fields cost $20.50 ± 3.14 per month on average over the entire 27-mo study duration including winter months when no maintenance was performed. Fleurance, G., P. Duncan, H. Fritz, I. J. Gordon, and M. F. Grenier-Loustalot. (2015) stated that rotational grazing of horses was associated with better forage quality, evidenced by higher concentrations of DE and soluble carbohydrates (WSC and sugar), and lower levels of fiber fractions (ADF, NDF, and lignin) compared with continuous grazing. Total cover of the pastures remained above 85% in R pastures and only dropped below 80% in C pastures in 1 mo (March 16). 1Weather data were obtained for the New Brunswick Station through the Office of the New Jersey State Climatologist website (http://climate.rutgers.edu/stateclim_v1/monthlydata). (1989, 2009, 2011) also reported no differences in horse body condition between grazing systems. To test for differences between treatment groups, many of the quantitative study outcomes were analyzed with repeated-measures analysis of covariance (ANCOVA) using SAS PROC MIXED (version 9.4, SAS Inst., Cary, NC). Data are shown as means and 95% CI. To control for seasonal variance, the month that measurements were taken was included in the models as a covariate when applicable. There were also 2 mo that were well above (more than 50% greater) historical average precipitation. The total cost for each field for the study duration was $647.09 for 2R, $565.82 for 3R, and $530.19 for each C pasture. Webb et al. All fields had initial VC and TC of 100%. Pros and Cons of Multi-species Grazing by AgWeb.com Editors | Read more Regional News about Agriculture and Crop Production on AgWeb. There was an effect of month for BW (P = 0.01), BCS (P < 0.0001), and FAT (P = 0.0005). The body of literature for continuous vs. rotational grazing in horses is comparatively limited. Carter, R. A., K. H. Treiber, R. J. Geor, L. Douglass, and P. A. Harris. Rotational grazing or subdividing larger pastures into smaller paddocks and moving the livestock from one to another every week or two has lots of benefits. Horse BW was measured using an IND221 electronic scale (Mettler Toledo, Columbus, OH), and BCS was assessed on a scale of 1 to 9 (Henneke et al., 1983). Herrick, J. E., J. W. Van Zee, K. M. Havstad, L. M. Burkett, and W. G. Whitford. Webb, G., S. Webb, C. Duey, and K. Minton. Webb, G. W., B. E. Conrad, M. A. Hussey, and G. D. Potter. The remaining two pasture condition measures, HEIGHT and MASS were evaluated using repeated-measures ANCOVA, blocking by field, and utilizing the seasonal covariate month. Extend the grazing season. The overall field composition by treatment (continuous [C] or rotational [R] grazing)1. When horses in the R systems did not have adequate grass (grass height depleted below 7.6 cm in all pasture sections) due to poor weather conditions (i.e., drought, snow, plant senescence), they were confined to a stress lot and fed grass hay at 2% BW per day to meet nutritional requirements (NRC, 2007) and maintain BCS at a minimum score of five. Burk et al. If you leave animals on a piece of land for too long, they’ll eat down some of the grass to the dirt while other areas will be ignored and the grass will grow too tall to be palatable. As for hay provided, we did feed supplemental feed for both treatments when forage was at a minimum to maintain horse body condition above a BCS of five. During this same timeframe, horses in C pastures essentially had ad libitum access to forage, as they were still allowed to graze pasture forage in addition to being offered supplemental hay. Throughout the project, recommended pasture management practices were followed as they relate to each system (Singer et al., 1999; Foulk et al., 2004; Burk et al., 2011). Another theory was that the forage sampling height could have contributed to more clover included in the C samples. (1996) found that horse grazing did not affect litter or rock cover (contributing to the difference between VC and TC) as much as it affected VC. MIRG for short. Data are shown as means and 95% CI. When considering these data, it is important to note that the four pastures were initially similar. The treatment differences in nutritional composition are very curious. Average horse body condition score (BCS) and body fat differed by treatment, with C horses (BCS 6.3 ± 0.05, 17.9 ± 0.15% body fat) greater than R horses (BCS 5.9 ± 0.05, 16.8 ± 0.15% body fat). Grazing, the interaction between plant and animal, is inextricably linked to agricultural grasslands. (2011) who harvested approximately 4,030 kg of hay from 2.08 ha of rotational pastures over 2 yr of grazing horses at a similar stocking rate as the current study. that were enclosed by permanent fencing; each R system was subdivided into four pasture sections (0.37 to 0.4 ha each) separated using temporary horse-friendly fencing (electric tape; Kencove Farm Fence, Blairsville, PA). The objective of this study was to determine whether rotational grazing generates horse, pasture, or cost benefits over continuous grazing. It is likely that, with additional years under the existing management, C pastures would be further degraded by constant trampling and grazing, while R pastures could be managed to minimize these effects. Rotational grazing increases the utilisation of grass grown, which allows you to increase stocking density in comparison to a set stocked system – a benefit if grazing land is in short supply or you want to expand the herd. Rotational pastures had higher VC than C for all but four of the 27 mo, two of those being the first 2 mo of measurements when they were not significantly different and again in September 2015. Hubbard, R. K., G. L. Newton, and G. M. Hill. Measures of pasture cover were also impacted by grazing management (R vs. C). 6B) were significantly higher with R (89.5 ± 0.4, 96.5 ± 0.5%, respectively) compared with C (78.4 ± 0.6, 89.1 ± 1.4%, respectively; P < 0.0001). However, since DE was significantly higher in the other treatment, we must assume that plant maturity was not the only factor. Rotationally grazed pasture sections were mowed and dragged monthly when forage was growing (after horses had been removed from the section), but they were smaller areas of land and therefore cost less per section for mowing/dragging. Vegetative cover is an indicator of the proportion of green forage available to horses in a pasture, while TC includes any item which covers the soil, living or dead, and is a better indicator of soil condition and erosion risk (Herrick et al., 2009). Field composition and species composition were compiled into frequency counts and were evaluated with Pearson’s Chi Square Test of Association using PROC FREQ in SAS. The following year (2013), due to poor initial establishment, pastures were over-seeded with the same species at 3.6, 14.5, and 7.3 kg/ha of the same seed, respectively, to establish a better stand. Digestible energy ranged from 2.1 ± 0.01 to 2.8 ± 0.01 Mcal/kg, whereas the present study included values as low as 1.5 Mcal/kg in the winter months to 2.3 Mcal/kg during the early spring months. 3ESC, ethanol soluble carbohydrates; SEM, standard error of the mean; WSC, water soluble carbohydrates. 1). Alison J. Eagle, Lydia P. Olander, in Advances in Agronomy, 2012. Heady (1961) notes that, in an attempt to uniformly defoliate the pasture, rotational grazing forces animals to consume the lower-quality forage that normally would be ignored. The disadvantages of rotational grazing include the need for more fence to be constructed, time required to move cattle, and the need to have water and access to shade from each smaller paddock. The effect of grazing system on vegetation was measured monthly, weather permitting. Data are shown as means and 95% CI. Upon completion of this current study, a follow-up study was conducted to evaluate recovery of pasture forage production in C vs. R pastures after a period of rest (or grazing exclusion) (Weinert and Williams, 2018). Kentucky bluegrass is a rhizomatous sod-forming grass which better tolerates close grazing than bunch grasses (Martinson et al., 2015). A major goal is to provide quality pasture for the grazing animals throughout the grazing season. The results here support the recommendation of rotational grazing for production, environmental, and ecological purposes. Values from the present study are similar, with R pregraze heights ranging from about 20 to 25 cm during the peak grazing months of June and July for both years. The young, rapidly growing plants seen in April are immature and contain a high level of nonstructural carbohydrates, which contribute to the high DE. Chemical weed control was not performed so as to track natural changes in plant species composition including weed growth. Weather data were tracked using the Rutgers Historical Monthly Station Data website (Rutgers Office of the State Climatologist, 2015; http://climate.rutgers.edu/stateclim_v1/monthlydata) for the New Brunswick station and included monthly average temperature, average precipitation, and historical monthly averages. While not particularly attractive, this poses no health concern to the horse. This agrees with work by McIntosh (2007), who found that sugars, fructans, and starch in a TF pasture were highest in April. The results of this study showed that winter rest alone was not sufficient to mitigate the effects of overgrazing in C pastures. This means that the pasture sections had 3 or more weeks of regrowth before the measurements were made, as compared with the C fields which were never rested. 3; P < 0.0001); however, no significant difference for BW. Final VC and TC were 95.5 ± 0.5% and 88.0 ± 4%, respectively, for R pastures and 81.5 ± 5.5% and 63.0 ± 3%, respectively, for C pastures. Clippings were compiled, and one sample from each of the four fields was submitted for analysis each month. Precipitation totals were also near average for most months except for 4 mo that were 50% to 60% and 8 mo that were only 20% to 40% of historical averages. In conclusion, this study is one of the few exploring the impacts of rotational vs. continuous grazing of horses, and one of even fewer replicated, multiyear studies. Sward height and herbage mass were measured before R horses were allowed into a pasture section to assess the conditions that were available to horses. Immediately after grazing (prior to the rest period), each pasture section was dragged (to disperse manure) and remaining ungrazed forage was mowed to a height of 10 cm during the grazing season. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. In C pastures, forage yield only reached levels measured in R pastures after 9 mo of rest, and differences in species composition of pastures persisted throughout the duration of this recovery study (Weinert and Williams, 2018). Webb et al. During both winter seasons, all horses were fed a full hay diet at 2% BW and identical amounts of concentrate to maintain body condition. This study is one of few replicated experiments comparing the effects of rotational and continuous grazing for horses on pasture quality, horse condition, and production costs. Charts presented display the data as means ± standard error. Twelve Standardbred mares (initial age 14 ± 2 yr, BW 544 ± 47 kg [mean ± SD], and BCS 6.1 ± 0.47) were paired by initial BW and BCS and randomly assigned to either the R or C grazing systems. Vegetative cover (VC; measure of living plant cover) and total cover (TC; measure of any soil cover, dead or alive) were estimated using a modified Step Point method (Evans and Love, 1956; Kenny et al., 2018) with 100 observations per pasture; in R pastures, this was accomplished by dividing these observations so that 25 measures were collected in each of the four sections. The rotationally grazed (R) pastures are referred to as 2R and 3R, and the continuously grazed (C) pastures are referred to as 2C and 3C (Fig. It was anticipated that the C pastures would provide less nutrition as they became overgrazed. Forage samples collected from C pastures were frequently clipped at ground level, where the prostrate legume common white clover (Trifolium repens) would be found. Additionally, the taller forage in the R pastures was sometimes overly mature and therefore lower in nutritional quality despite the high herbage mass available, which might have been evident in the higher ADF in the R pastures coupled with the lower CP, but it was not the case for NDF. Outside of the winter rest periods, the C horses grazed a total of 507 d, representing 100% of grazing time between August 1 and November 17, 2014, May 14 to December 3, 2015, and May 10 to November 22, 2016. Twelve Standardbred mares were grazed for an overall stocking rate of 0.52 ha/horse (n = 3 in each pasture). Our hypothesis was that the rotational grazing systems would result in increased horse condition; improved pasture yield and quality; and reduced overall maintenance costs. The C horses were fed 597 ± 34.1 kg and R horses were fed 659 ± 34.1 kg of hay per month on average during the months where hay was offered for the entire study duration. Once R horses were returned to pastures, they required less hay or none at all, while C horses needed more supplementation due to the damage caused to their pastures over the winter. The lack of differences in maintenance costs along with hay fed was also contrary to our hypothesis, but is understandable given the fact that we followed good pasture management and stocking density practices even in the continuously grazed pastures, with mowing and dragging as needed to aid in controlling weeds and breaking up accumulated manure. While herbage mass was significantly higher for R fields, even the baseline yields were lower than some previously reported values. The effects of grazing system on pasture condition were significant, with rotational pastures showing higher sward heights, herbage mass, and VC. It’s healthier for the pasture. There was also a significant effect of month for both measures (P < 0.0001). Perception of Rotational Grazing Benefits: Non-Users vs. Users. This was also found to be true in the present study. Results were analyzed in SAS (V9.4) using mixed model repeated-measures analysis of covariance, chi-square tests of association, and two-sample t-tests. Obesity is a primary risk factor for the development of insulin resistance and episodes of pasture-associated laminitis (Carter et al., 2009). Our finding of higher condition in C horses compared with R horses was unexpected but explainable. However, an extension of this recovery study protocol would be necessary to provide a complete assessment of long-term effects of C vs. R management strategies in horse pastures. Welcome to the rotational grazing system series for suckler producers. Furthermore, Olson-Rutz et al. Henneke, D. R., G. D. Potter, J. L. Kreider, and B. F. Yeates. Excluding winter rest periods, the C horses were fed a total of 4,657.6 ± 299 kg hay and R horses were fed a total of 5,392 ± 1,260 kg hay. a–dMonths within columns with a similar superscript are not significantly different (P < 0.05). The impact of grazing was not immediate, as it took time for trampling and defoliation to damage the pastures. Therefore, some months did not have all four sections measured, and the measures for each section were not always performed on the same day. Regenerative practices helped sequester 2.29 milligrams of … Rotational grazing allows you to graze other livestock on a piece of land. Vegetative cover and TC are similar but have slightly different implications. The grazing plan will change as grass growth may not do what is predicted or the weather becomes a factor. By Kenzi Knapp. The average length of grazing bout per rotational grazing section increased numerically over time, presumably as the forage roots matured, and was 7.88 ± 0.76 d in 2014, 10.0 ± 0.61 d in 2015, and 10.9 ± 0.80 d in 2016. After looking at the monthly pattern, the authors believe this was either due to a sampling error or possibly the high temperatures coupled with the low rainfall in the 2 mo prior (July 15 = 54 and August 15 = 25% of historical averages). Therefore, it is possible that the nutritional analysis of our randomly selected samples did not accurately represent the plants selected by the horses. Martinson, K. L., M. S. Wells, and C. C. Sheaffer. However, the bulk of these studies were performed on rangeland rather than improved cool-season grass pastures such as those evaluated in the current study. During the winter of 2014 to 2015, overall horse condition decreased such that supplemental concentrate (EQUI-PRO E-TEC, Poulin Grain, Newport, VT) was fed at the rate of 1.8 kg/horse for all twelve horses. The rotationally grazed (R) fields are 2R and 3R, where the continuously grazed (C) fields are 2C and 3C. Rutgers University Office of the State Climatologist. There were significant differences between treatments for average horse BCS (Fig. There were no significant differences between treatments for average monthly amount of hay fed or cost of pasture maintenance. The preponderance of research in other livestock species has found that adopting rotational grazing practices does not result in greater animal condition (summarized by Holechek et al., 1999; Briske et al., 2008). Continuously grazed fields were mowed and dragged twice during the first grazing season, dragged in the early spring to disperse manure accumulated over the winter, and then mowed and dragged once in the summer to even forage height and control weeds. For outcome measurements on horses (i.e., BW, BCS, and FAT), repeated-measures ANCOVA was conducted, blocking by field, nested in horse, with seasonal covariate month. Williams et al. If haymaking equipment had been available, this could have been an opportunity to preserve the forage as hay and realize a cost savings, as illustrated by Burk et al.

This inconsistency could be due to the warmer weather in a more southern climate allowing pastures to be productive through the winter. Published by Oxford University Press on behalf of the American Society of Animal Science. This work was supported by the USDA National Institute of Food and Agriculture Hatch project 1003557 through the New Jersey Agricultural Experiment Station, Hatch project NJ06170 and the Rutgers Equine Science Center (57 US 1, New Brunswick, NJ 08901). cMonthly amount was over 50% greater than monthly historical average. The cons over rotational grazing may include, having to be able to take time to rotate your cows and the cost of putting up cross section fencing in your pastures. The main finding from this study was that rotational grazing did result in improved pasture condition and quality but did not result in increased horse condition and reduced maintenance costs. Soil fertility was adjusted to optimum with lime and fertilizer, and pastures were seeded with Jesup MaxQ endophyte-friendly tall fescue (TF) (Festuca arundinacea; Pennington Seed, Madison, GA) at 7.9 kg/ha, Camas Kentucky bluegrass (KB) (Poa pratensis) at 12.9 kg/ha, and Potomac orchardgrass (OG) (Dactylis glomerata) at 8.2 kg/ha (both from Chamberlin & Barclay, Cranbury, NJ). 2Chi-square (3 df, n = 9,600) = 540.6, P < 0.0001. The growing pattern of grass defines it. Rotational grazing also has the potential to reduce machinery cost, fuel, supplemental feeding and the amount of forage wasted. Briske, D. D., J. D. Derner, J. R. Brown, S. D. Fuhlendorf, W. R. Teague, K. M. Havstad, R. L. Gillen, A. J. Ash, and W. D. Willms. Rotational grazing might seem like a very simple concept, however, this simplicity has great benefits for the entire ecosystem. By having multiple areas or paddocks to graze, the stock will get a continual supply of high quality grass before returning to the first paddock. In any case, all but two horses remained below a BCS of 7, which is the threshold for overweight/obesity on the Henneke scale of 1 to 9. This was found to be true for the tall grasses, TF and OG, and the weed category, but the short grass, KB, was not affected by grazing. However, horses in 2R grazed 375 d and horses in 3R grazed 441 d, which represents 74.0% and 87.0%, respectively, of the grazing days C horses grazed. The different herbage mass values seen in the present study may be due to maturity of the grasses at time of sampling, soil physical properties or weather conditions, as soil fertility was optimized before the study began and tested yearly. However, in the present study, differences in BCS and FAT became more pronounced later in the study period, while samples for the sugar metabolism companion study (Williams et al., 2019) were collected only during the first full grazing season of this study (2015). Most of the Midwest grasslands are managed under continuous grazing practice, under which livestock graze the entire pasture season long without any grass recovery period. Soil in these fields were loam and silty clay loam primarily composed of FapA (Fallsington loams, 0% to 2% slopes, Northern Coastal Plain) with NknB (Nixon loam, 2% to 5% slopes) and NkrA (Nixon moderately well drained variant loam, 0% to 2% slopes).

Although there are a couple cons i think that rotational grazing is very beneficial and well worth a try. But well-managed rotational grazing means that you evaluate the nutritional and forage needs of your animals, assess forage quality and quantity, regulate the acreage of access and control which parts of the pasture/range that the animals have access to.
