Warm-season grasses tend to accumulate lower WSC content than cool-season grasses due to lower fructan synthesis (Chatterton et al., 1989). 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. Williams et al. Sward height within each treatment (continuous grazing system = C and rotational grazing system = R). Data are shown as means and 95% CI. Months with CI gaps between treatments are different at P < 0.05. Regenerative practices helped sequester 2.29 milligrams of … Season did have an effect on both forage nutrient content and glucose metabolism of the horses in that previous report, which is similar to other previous studies on seasonal nutrient content and horse sugar metabolism (McIntosh, 2007). When considering these data, it is important to note that the four pastures were initially similar. Shifts in species composition were seen between treatments and months. Months with CI gaps between treatments are different at P < 0.05. (2015) compared effects of continuous vs. rotational equine grazing systems on pasture condition and nutrient content over 2 yr. Virostek et al. Spring recovery of pasture forage yield was depressed in C pastures compared with R pastures and this divergence remained for the duration of the study. This video highlights a rotational grazing demonstration using Vence Cattle Manage System. Rotational Grazing Benefits: South Dakota Producer Perceptions. Compared with C, R had higher proportions of G and W and lower proportions of GW and O. 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. 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). Fat thickness was measured on both sides of the rump, and the average was entered into a regression equation to determine overall body fat percentage (Westervelt et al., 1976). 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. It was anticipated that C horses would require more hay than R horses due to diminished pasture conditions, but several factors contributed to this not being the case. The C pastures contained temporary run-in shelters, water sources, and hay feeders. There is clearly a need for research studying horse grazing on improved pastures over multiple grazing seasons with replication and robust statistics. Horse BW, BCS, and percent body fat (FAT) were measured monthly to determine the effect of grazing system on horse health. Fleurance, G., P. Duncan, H. Fritz, I. J. Gordon, and M. F. Grenier-Loustalot. Obesity is a primary risk factor for the development of insulin resistance and episodes of pasture-associated laminitis (Carter et al., 2009). Foulk, D. L., R. C. Mickel, E. A. Chamberlain, M. Margentino, and M. Westendorf. To control for seasonal variance, the month that measurements were taken was included in the models as a covariate when applicable. 2Chi-square (3 df, n = 9,600) = 184.6, P < 0.0001. Body fat percentage for horses within each treatment (continuous grazing system, C, n = 6 and rotational grazing system, R, n = 6). If you have not switched to rotational grazing for your pet friend yet, you will genuinely be surprised by what it has to offer in the long run.

In agriculture, rotational grazing, as opposed to continuous grazing, describes many systems of pasturing, whereby livestock are moved to portions of the pasture, called paddocks, while the other portions rest. 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. Kentucky bluegrass is a rhizomatous sod-forming grass which better tolerates close grazing than bunch grasses (Martinson et al., 2015). Total cover of the pastures remained above 85% in R pastures and only dropped below 80% in C pastures in 1 mo (March 16). Forage intake under ad libitum conditions can exceed 3% of BW per day, well in excess of the maintenance requirement (NRC, 2007; Smith et al., 2007). 3ESC, ethanol soluble carbohydrates; SEM, standard error of the mean; WSC, water soluble carbohydrates. Throughout the United States, cattle ranchers have been using an increasingly popular grazing technique known as intensive grazing or mob grazing. It can also be more beneficial to the grass because the cows cant overgraze it if you are controlling when they get moved off of the grass. 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. Recovery of a high elevation plant community after packhorse grazing, Horses and cattle grazing on the Wyoming Red Desert, III, Rutgers University Office of the State Climatologist. Charts presented display the data as means ± standard error. Perception of Rotational Grazing Benefits: Non-Users vs. Users. Therefore, some months did not have all four sections measured, and the measures for each section were not always performed on the same day. However, by establishing each pasture similarly, we can observe how much each pasture has deviated from a similar baseline and implement controls for pasture management practices allowing for a more direct comparison of production and species composition variables across pastures and grazing systems. ( Log Out /  However, R had higher DE and ADF, while C had higher CP. However, the condition of the horses did not suffer while they were grazing, and some horses even reached a BCS above seven, so it is clear that the quality was adequate in all pastures. Thus, it is likely that even during times of low forage availability in C pastures due to environmental conditions and overgrazing, horses were able to consume enough forage to exceed the maintenance requirement leading to weight gain. (2010). Welcome to the rotational grazing system series for suckler producers. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. Plumb, G. E., L. J. Krysl, M. E. Hubbert, M. A. Smith, and J. W. Waggoner. 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.) 5) had a significant effect of treatment (P < 0.0001) with R being greater (11.8 ± 0.1 cm tall; 1,513.0 ± 41.2 kg/ha) than C pastures (6.9 ± 0.1 cm tall; 780.6 ± 34.7 kg/ha). Step 1. (2009, 2011) also measured pregrazing herbage mass and found that a rotational grazing system produced higher yield over a 4-yr period than continuous grazing. Often times rotations are set. 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.). (2011). There was also a significant effect of month for both measures (P < 0.0001). Rotational grazing with the correct stocking rate will maintain adequate stubble height and carbohydrate reserves after grazing to maximize forage regrowth. Unhealthy Goat Grazing Led to a Health Crisis. It is important to note that June 2015 was one of the months with over 50% higher precipitation than the historical average. (2011) found that “multi-paddock” rotational grazing pastures had less bare ground than pastures that were continuously grazed. When livestock graze large pastures, they tend to repeatedly graze preferred areas. The average length of grazing bout per rotational grazing section during the grazing season increased numerically each year from 7.88 ± 0.76 d in 2014, 10.0 ± 0.61 d in 2015, and 10.9 ± 0.80 d in 2016. It’s healthier for the pasture. It can also be more beneficial to the grass because the cows cant overgraze it if you are controlling when they get moved off of the grass. The cost of maintenance on each system was compared by recording the number of times of each pasture unit mowed and dragged. Twelve Standardbred mares were grazed for an overall stocking rate of 0.52 ha/horse (n = 3 in each pasture). This agrees with work by McIntosh (2007), who found that sugars, fructans, and starch in a TF pasture were highest in April. (2015) observed no difference in biomass yield between systems, but botanical composition shifted toward a higher proportion of grasses and lower weeds in the rotational system. The grazing plan will change as grass growth may not do what is predicted or the weather becomes a factor. Singer, J. W., N. Bobsin, W. J. Bamka, and D. Kluchinski. (2011). An observational study in Maryland reported benefits of rotationally grazing horses at a low stocking rate (0.49 ha/horse), although a comparison with continuous grazing was not included. There were only 4 mo during which C fields had higher TC than R fields: three of those being the first 3 mo of the study and the other was in May 16. Olson-Rutz, K. M., C. B. Marlow, K. Hansen, L. C. Gagnon, and R. J. Rossi. Therefore, the objective of this study was to compare the effects of rotational and continuous grazing on horse and pasture condition, and production costs in replicated pastures over multiple grazing seasons. Dividing up a pasture into paddocks to prevent overgrazing goes back to the earliest agr Body condition score (BCS) for horses within each treatment (continuous grazing system, C, n = 6 and rotational grazing system, R, n = 6). 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. Daniel, A. D., B. J. McIntosh, J. D. Plunk, M. Webb, D. McIntosh, and A. G. Parks. The moment that occurs, the moment the sheep graze this regrowth, the pasture rotation no … When the forage began to regrow and horse BCS increased, concentrate was discontinued but hay was still fed. Both NDF (cellulose, hemicellulose, and lignin) and ADF (cellulose and lignin) were lowest in the early spring months when the DE was at its highest. Monthly average temperature, total precipitation, and average relative humidity are listed in Table 2, historical monthly averages are listed in Table 3. Webb, G., S. Webb, C. Duey, and K. Minton. Rutgers University Office of the State Climatologist. Horses were fed similar amounts of hay throughout the study. Henneke, D. R., G. D. Potter, J. L. Kreider, and B. F. Yeates. Average monthly hay and maintenance costs did differ by month (P < 0.0001). You guessed it! Change ), You are commenting using your Facebook account. 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). Forage quality values of the pastures were slightly lower than those reported by McIntosh (2007) for Virginia TF pastures. The remaining two pasture condition measures, HEIGHT and MASS were evaluated using repeated-measures ANCOVA, blocking by field, and utilizing the seasonal covariate month. Fleurance et al. Black lines indicate permanent fencing and white lines indicate temporary electric tape fencing separating rotational fields. 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). Furthermore, Olson-Rutz et al. Samples were collected monthly between 0800 and 1000. (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. However, there were no differences in supplemental hay fed or maintenance costs between the grazing systems. Agricultural grasslands are defined (Peeters et al., 2014) as land devoted to the production of forage for harvest by grazing/browsing, cutting, or both, or used for other agricultural purposes such as renewable energy production. Daniel et al. 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. Grassland soils are a great reservoir for organic carbon. Overall, the average monthly grazing days was greater for C (29.6 d) vs. R (14.1 d; P < 0.0001) over the course of the 27-mo study. 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. The tall, fibrous stems are reported to be higher in ADF and NDF and lower in CP compared with perennial ryegrass stems (Stewart, 1996), and these stems would have been included with taller R forage samples. Nutrient composition of pastures (DM basis) in the rotational and continuous grazing systems combined for each month across the study duration1. 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). Search for other works by this author on: Present address: Penn State Extension Montgomery County, Collegeville, PA 19426. 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. There were significant differences between treatments for average horse BCS (Fig. In fact, horse BCS and FAT were lower in the rotationally grazed horses as compared with the continuously grazed horses. The difference in proportion of KB was not statistically significant. Field composition frequency counts for TC show that there is an association between field composition and treatment (Table 5; P < 0.0001). (2015) found a range of 6,100 to 7,082 kg/ha observed in a full season of grazing cool-season grass mixtures grown in Minnesota (Martinson et al., 2015); however, these numbers are difficult to compare to those in the current study as pasture yields in Martinson et al. This was also found to be true in the present study. The 2R stress lot has gates opening into each rotational field. 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. Vegetative cover and TC are similar but have slightly different implications. The growth rate of the plants are not considered nor the recovery time of plants after grazing. Pregraze height values reported by Burk et al. Rotational grazing is nothing new. Rotational grazing involves using small fields sizes, (or paddocks) to move stock frequently to provide a rest for the grass and reduce wastage. Grazing Periods:Grazing Periods: 7 7 -- 14days14days Rest Periods: 20 Rest Periods: 20 –– 40 days40 days Stock density: 5000 Stock density: 5000 –– 10,000 lbs./ac10,000 lbs./ac Utilization: 30 Utilization: 30 –– 45%45% Higher degree of selectivity Rotational Grazing Spot grazing still a problem Chatterton, N. J., P. A. Harrison, J. H. Bennett, and K. H. Asay. The C horses were maintained on pasture for 100% of the study duration (844 d; August 1, 2014 to November 22, 2016), while R horses had access to pasture for approximately half of this time (408 ± 33 d). Similar to above for VC, this corresponds to a month that fell directly after poor precipitation compared with historical averages. 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. Coleman and Barth (1973) found that grazing animals may consume a higher quality diet than the average quality of the pasture by selecting certain plants over others. This distance was not recorded in the present study but is believed to be similar to observations of the C pastures. 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. Something that many people in the cattle industry are promoting is rotational grazing. Benefits included increased horse body weight (BW) and body condition score (BCS), high vegetative cover (VC) and low weeds, and enhanced economic value as forage grown in excess of horses’ requirements was harvested for hay (Burk et al., 2011). ( Log Out /  High plant cover improves water quality by reducing erosion, taking up nutrients that may otherwise leave the pasture in stormwater runoff, and slowing the flow of surface water which may be contaminated by nutrients or sediment (Hubbard et al., 2004). (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. 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. 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. Pros: According to Beef Magazine, intensive grazing is more natural for cattle because… aMonthly amount was 50–60% of monthly historical average. The cattle or livestock will often times rotate in the same pattern through the same pastures each year. In 2012, pasture fields were chemically treated to eliminate the existing vegetation, plowed to a depth of approximately 18 cm, disked, and pasture forage was reestablished. Grazing pressure is adjusted by adding or subtracting animals or temporarily fencing off areas for hay harvest. Many people will fence their pasture into 4 sections and rotate the cows as frequently as needed. 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). McIntosh (2007) found an average monthly forage biomass yield of 2,612 kg/ha over 4 mo (April, August, October, and January) in TF pastures in Virginia. The results here support the recommendation of rotational grazing for production, environmental, and ecological purposes. That's a mouthful. (1984) also observed large decreases in cover extending up to 61 m away from a water source when used by horses and/or cattle. Conflict of interest statement. The growing pattern of grass defines it. 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. 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). T-tests show the difference of proportions is statistically significant in all categories (P < 0.0001). Information provided in this brochure can help you plan to attain this goal. The months that did drop below the 70% rule were those in the winter months for all pastures and very early spring in the C pastures. Carey A Williams, Laura B Kenny, Jennifer R Weinert, Kevin Sullivan, William Meyer, Mark G Robson, Effects of 27 mo of rotational vs. continuous grazing on horse and pasture condition, Translational Animal Science, Volume 4, Issue 3, July 2020, txaa084, https://doi.org/10.1093/tas/txaa084. However, taller swards and more available forage per ha do not necessarily equate to a higher plane of nutrition for grazing horses. Rotational grazing (also known as management-intensive grazing, MIG) differs from continuous grazing in that land is separated into smaller paddocks and the group of animals is moved regularly between paddocks. 6A) and TC (Fig. By summer’s end our ladies made it clear that grass was great, but our many trees fit their browsing desires more nicely. The samples were weighed before and after drying at 65 °C for at least 36 h in a Thermocore oven to calculate dry matter (DM) and then ground to 1 mm using a Wiley Mill and sent to Equi-Analytical Laboratories (Ithaca, NY) for wet chemistry of DE, crude protein (CP), acid detergent fiber (ADF), neutral detergent fiber (NDF), water soluble carbohydrates (WSC), ethanol soluble carbohydrates (ESC), starch, Ca, and P on a DM basis. The Rutgers University Institutional Animal Care and Use Review Board approved all methods and procedures used in this experiment (Protocol # 04-005). Monthly weather conditions during each month of grazing horses in New Brunswick, NJ plus the month of baseline sampling, July 20141. Holechek, J. L., H. Gomez, F. Molinar, and D. Galt. (1989, 2009, 2011) also reported no differences in horse body condition between grazing systems. Vegetative cover values during the grazing season were higher than those reported by Burk et al. 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). Department of Animal Science, Rutgers, The State University of New Jersey. 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. Many graziers use temporary electric fence systems to manage the size of the paddock. 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. Total cover also includes some trampled plant material or litter, which may contribute to soil organic matter as it is decomposed by microbes in soil (Voroney, 2019). Both HEIGHT (Fig. The first monthly samples were collected in the first week of September 2014 following one full month of grazing. Our finding of higher condition in C horses compared with R horses was unexpected but explainable. Change ), You are commenting using your Twitter account. Volume II: Design, supplementary methods and interpretation, Equine behavior problems in relation to humane management, Voluntary intake and controlled grazing of horses, Technical note: Comparing 4 techniques for estimating desired grass species composition in horse pastures, Horse preference, forage yield and species persistence of twelve perennial cool-season grass mixtures under horse grazing, Circadian and seasonal variation in pasture nonstructural carbohydrates and the response of grazing horses. For R fields, MASS was measured immediately prior to grazing to estimate the amount of forage available to the horses. Webb et al. ( Log Out /  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. 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. Introduction to My Pasture Pigs Rotational Grazing Paddock Design. Measures were not taken when ground was snow-covered (December 2014, February and March 2015, and February 2016). Specifically, for the R system, horses were grazed when forage was taller than 15.2 cm and removed when available forage was depleted to a level of 7.6 cm. Collected samples were then dried at 65 °C for at least 36 h in a Thermocore oven (Cayley and Bird, 1996). 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. and State Univ. The body of literature for continuous vs. rotational grazing in horses is comparatively limited. Other (O) represents all other vegetation (living or dead), plus bare ground, rocks, litter, etc. 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). This is not considering any long-term maintenance that might be needed such as over-seeding, fertilization, or herbicide applications to bring C pasture up to the same pasture condition as the R pastures at the end of the study. For more details on the soluble carbohydrate differences in these systems and the effect on sugar metabolism in these horses, see a companion study, Williams et al. The key to rotational grazing or trying to expand the grazing season with pasture management is to try a new idea, on a small scale, before you change your whole system. The young, rapidly growing plants seen in April are immature and contain a high level of nonstructural carbohydrates, which contribute to the high DE. Pregraze sward heights were significantly taller in R fields due to the rest period when pastures could regrow. Chemical weed control was not performed so as to track natural changes in plant species composition including weed growth. As discussed above for pasture condition, evaluating horses maintained under these grazing strategies over additional years will provide useful information to determine if rotational grazing offers long-term benefits for controlling weight and preventing deterioration of metabolic health in the grazing horse.
