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. There were no significant differences between treatments for average monthly amount of hay fed (C, 597 Â± 34.1 vs. R, 659 Â± 34.1 kg) or average monthly pasture maintenance cost (C, $17.55 Â± 3.14 vs. R, $20.50 Â± 3.14). The pastures in this study remained above 70% VC during almost all months of the study. Interactions were also tested. Monthly weather conditions during each month of grazing horses in New Brunswick, NJ plus the month of baseline sampling, July 20141. The results here support the recommendation of rotational grazing for production, environmental, and ecological purposes. Often times rotations are set. Pasture composition data showed similar proportions of clover in R and C; however nutrient analysis found greater Ca in R pastures, which is contrary to what one would expect if more clover were collected from C pastures. Average horse body condition score (BCS) and body fat differed by treatment, with C horses (BCS 6.3 Â± 0.05, 17.9 Â± 0.15% body fat) greater than R horses (BCS 5.9 Â± 0.05, 16.8 Â± 0.15% body fat).

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. You guessed it! 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). Baseline samples of all measures were collected in July 2014 (month 0), and horses were turned out on August 1, 2014 at a stocking rate of 0.52 ha/horse as recommended by Singer et al. 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 â¦ Field composition frequency counts for TC show that there is an association between field composition and treatment (Table 5; P < 0.0001). 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. 2Chi-square (3 df, n = 9,600) = 540.6, P < 0.0001. 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. Nitrogen was applied to all fields simultaneously in the early spring prior to initiation of rotational grazing and again in midfall yearly; at this time all horses were removed from the pastures and placed in stress lots for a period of 2 d. Nitrogen was applied every spring and soil tests were conducted yearly on all pastures and determined that other fertilization was not necessary during the study period. Final VC and TC were 95.5 Â± 0.5% and 88.0 Â± 4%, respectively, for R pastures and 81.5 Â± 5.5% and 63.0 Â± 3%, respectively, for C pastures. In fact, horse BCS and FAT were lower in the rotationally grazed horses as compared with the continuously grazed horses. Smith, D. G., R. W. Mayes, T. Hollands, D. Cuddeford, H. H. Yule, C. M. Ladrero, and E. Gillen. 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. Sward height (HEIGHT) was measured by dropping a Styrofoam plate down a meter stick and recording the height where it rested on the forage, as described by Burk et al. 6.3 Implement rotational grazing. There was an effect of month for BW (P = 0.01), BCS (P < 0.0001), and FAT (P = 0.0005). Compared with C, R had higher proportions of G and W and lower proportions of GW and O. The average length of grazing bout per rotational grazing section during the grazing season increased numerically each year from 7.88 Â± 0.76 d in 2014, 10.0 Â± 0.61 d in 2015, and 10.9 Â± 0.80 d in 2016.

Body condition score (BCS) for horses within each treatment (continuous grazing system, C, n = 6 and rotational grazing system, R, n = 6). 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. Pros of rotational grazing can allow you to run more cows on less grass. The growing pattern of grass defines it. 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. Furthermore, horses in R pastures were restricted to a stress lot during times of low forage availability, such as during the late summer to early fall when hot, dry temperatures led to a decrease in the vigor of cool-season pasture grasses. This was also found to be true in the present study. (2010) measured NDF during July and September. Grazing pressure is adjusted by adding or subtracting animals or temporarily fencing off areas for hay harvest. There was a significant effect of treatment for DE (P = 0.04), ADF (P = 0.033), and Ca (P = 0.005) with each being higher in R (2.03 Â± 0.02 Mcal/kg, 34.6 Â± 0.6%, 0.62 Â± 0.02%, respectively) vs. C (1.97 Â± 0.02 Mcal/kg, 32.9 Â± 0.6%, 0.53 Â± 0.2%, respectively) pastures; however, CP was higher in C (18.2 Â± 0.44%) vs. R (16.6 Â± 0.44%) pastures (P = 0.007). In fact, WSC (includes sugars and fructans) and ESC (sugars only) were also highest during these times. Our hypothesis was that utilizing rotational grazing management would result in increased horse condition; improved pasture condition and quality; and reduced overall maintenance costs. MIRG is a system of pasturing animals to maximize pasture growth.

Samples were collected monthly between 0800 and 1000. Fleurance et al. Virostek et al. Therefore, it is possible that the nutritional analysis of our randomly selected samples did not accurately represent the plants selected by the horses. 3ESC, ethanol soluble carbohydrates; SEM, standard error of the mean; WSC, water soluble carbohydrates. Extend the grazing season. Rotational grazing supports more diverse bird communities, more amphibians and were just as good as grassy buffers in regards to bank stability and in-stream habitat. Singer, J. W., W. J. Bamka, D. Kluchinski, and R. Govinasamy. Williams, C. A., L. B. Kenny, and A. O. Burk. Forage quality values of the pastures were slightly lower than those reported by McIntosh (2007) for Virginia TF pastures. In the present study, DE was highest in the early spring months (April and May) of both full grazing seasons. 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. 1Grasses planted included KB, OG, and TF. Change ). 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. cMonthly amount was over 50% greater than monthly historical average. The study established two replicates (1.57 ha each) of rotational (R; four grazing sections and a stress lot per replicate, where horses were fed a moderate quality grass hay at 2% of body weight when not grazing) and continuous (C) grazing systems (treatments).

That sounds simple but its time calculation is based on numerous factors â including moisture, type and quality of grass available, and the number of animals. Rotational grazing is a method of controlled grazing where stock are allowed to graze an area for a set amount of time before being moved into fresh grass. 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. Other (O) represents all other vegetation (living or dead), plus bare ground, rocks, litter, etc. 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. At some point, this regrowth becomes desirable enough for sheep to be grazed again. 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. When considering these data, it is important to note that the four pastures were initially similar. Teague et al. To explore the whole series click here . By summerâs end our ladies made it clear that grass was great, but our many trees fit their browsing desires more nicely. 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). Itâs healthier for the pasture. Vegetative cover (A) and total cover (B) within each treatment (continuous grazing system = C and rotational grazing system = R). This suggests that the forage was least fibrous and most digestible during that time. 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, the fact that the flock was moved from one pasture to another does not constitute rotational grazing. In the present study, the NDF concentrations of the forages during these months ranged from 55% to 60%, which is similar to values reported by Fleurance et al. As horses maintained on rotational pastures had lower BCS and FAT, this suggests that rotational grazing practices may potentially offer an advantage for those trying to control weight and avoid obesity in the grazing horse. Prior to the start of grazing (at least 2 mo), horses were housed in their respective groups on dry lots and fed a moderate quality grass hay at 2% of BW. However, since DE was significantly higher in the other treatment, we must assume that plant maturity was not the only factor. Step 1. Rotational grazing increases the utilisation of grass grown, which allows you to increase stocking density in comparison to a set stocked system â a benefit if grazing land is in short supply or you want to expand the herd. The difference in proportion of KB was not statistically significant. 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. (2011) for rotationally grazed fields only were 28.2 Â± 2.8 and 18.3 Â± 3.3 cm in years 1 and 2, respectively. The R horses were mostly confined for the winter starting in November. (2002) and Burk et al. 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. Fill in your details below or click an icon to log in: You are commenting using your WordPress.com account. Twelve Standardbred mares were grazed for an overall stocking rate of 0.52 ha/horse (n = 3 in each pasture). This could have been avoided by using portable water troughs and feeders that could be moved to different locations throughout the pasture; however, this was not possible under the current studyâs management conditions. (2015) compared effects of continuous vs. rotational equine grazing systems on pasture condition and nutrient content over 2 yr. Virostek et al. The first monthly samples were collected in the first week of September 2014 following one full month of grazing. Our hypothesis was that the rotational grazing systems would result in increased horse condition; improved pasture yield and quality; and reduced overall maintenance costs. 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. 1). ( Log Out / The problem with rotational grazing is âmoving livestock between paddocks every set number of days.â Pasture does not respond to grazing the same way throughout the growing season. When forage was tall, samples were clipped to 7 to 10 cm (grazing height) and when forage was less than 7 cm, samples were clipped at ground level to imitate horse grazing. 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. 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). 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. 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. 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). In contrast, rotational grazing can dramatically increase animal performance and forage DM yield per hectare. There were also 2 mo that were well above (more than 50% greater) historical average precipitation. (2011) of 78 Â± 3% and 80 Â± 2% (years 1 and 2, respectively), which are still acceptable by the 70% rule. Continuous grazing did not have a large impact on pasture condition until the first full grazing season. 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. 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). 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. Other measurements included the monthly averages for amount of hay fed, grazing days, and maintenance costs. Shifts in species composition were seen between treatments and months. There were no significant differences between treatments for average monthly amount of hay fed or cost of pasture maintenance. 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). The body of literature for continuous vs. rotational grazing in horses is comparatively limited. (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. The samples were weighed before and after drying at 65 Â°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. Rotational Grazing Benefits: South Dakota Producer Perceptions. Rotational grazing involves using small fields sizes, (or paddocks) to move stock frequently to provide a rest for the grass and reduce wastage. Data are shown as means and 95% CI. There was high VC, tall swards, and high herbage mass. The only month where C was higher than R was in May 16, this could be due to slow spring growth in R fields, again possibly due to lower than average precipitation in the months prior. Although there are a couple cons i think that rotational grazing is very beneficial and well worth a try. 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. There was also a significant effect of month for both measures (P < 0.0001). T-tests show the difference of proportions is statistically significant in all categories (P < 0.0001). 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. 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. The forage quality in each grazing unit would initially be high, then would decrease as animals deplete the high-quality forage and are forced to consume the lower-quality forage that remains until they are rotated. 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). While not particularly attractive, this poses no health concern to the horse. Daniel et al. The average length of grazing bout per rotational grazing section increased numerically over time, presumably as the forage roots matured, and was 7.88 Â± 0.76 d in 2014, 10.0 Â± 0.61 d in 2015, and 10.9 Â± 0.80 d in 2016. 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. 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). Winter turnout of C horses influenced vegetation, as seen in sward height, herbage mass, and VC, which were reduced to lower levels in C pastures. The average concentrations over the 2 yr for WSC and sugars were about half or less of the concentrations in the current study. Kentucky bluegrass is a rhizomatous sod-forming grass which better tolerates close grazing than bunch grasses (Martinson et al., 2015). 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. Horses were fed similar amounts of hay throughout the study. Rutgers University Office of the State Climatologist. 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. 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). Managed Intensive Rotational Grazing. as compared with C pastures. 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). The effect of grazing system on vegetation was measured monthly, weather permitting. Both sward height and herbage mass were greater in R (11.8 Â± 0.1 cm tall; 1,513 Â± 41 kg/ha) than C pastures (6.9 Â± 0.1 cm tall; 781 Â± 35 kg/ha). However, taller swards and more available forage per ha do not necessarily equate to a higher plane of nutrition for grazing horses. 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. (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. Furthermore, Olson-Rutz et al. Weeds were more prevalent in R pastures than C, which is interesting considering TF and OG were also more prevalent in R. The higher proportion of weeds does not appear to reflect lower proportions of desirable grasses, so it may reflect lower proportions of GW and O combined. Kenny, L. B., D. Ward, M. G. Robson, and C. A. Williams. (1984) also observed large decreases in cover extending up to 61 m away from a water source when used by horses and/or cattle. Neutral detergent fiber and ADF describe fiber fractions and have implications in digestibility. Average monthly hay and maintenance costs did differ by month (P < 0.0001). Henneke, D. R., G. D. Potter, J. L. Kreider, and B. F. Yeates. 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. Interstudy comparisons are limited, however, by the large number of factors such as stocking density, environmental conditions, pasture species composition, and agronomic practices that may influence the productivity of the pasture and response of the animals grazing it. Therefore, some months did not have all four sections measured, and the measures for each section were not always performed on the same day. This was opposite of the expected outcome and an interesting finding given the greater DE of the forage in the rotational pastures. 2Chi-square (3 df, n = 9,600) = 184.6, P < 0.0001. Months with CI gaps between treatments are different at P < 0.05. Department of Animal Science, Rutgers, The State University of New Jersey. Then add 30 minutes to one hour of grazing time each day, or as recommended by your veterinarian. Rotational grazing like most things has its pros and cons. To control for seasonal variance, the month that measurements were taken was included in the models as a covariate when applicable.
