Data collected with this method also allowed for estimation of the species composition of the pastures, including TF, KB, OG, grass weeds (GW), weeds (W), and other (O; i.e., rocks, litter, bare ground, etc.). Smith, D. G., R. W. Mayes, T. Hollands, D. Cuddeford, H. H. Yule, C. M. Ladrero, and E. Gillen. Rotational grazing might seem like a very simple concept, however, this simplicity has great benefits for the entire ecosystem. 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. 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. Example: A beef cow herd of thirty 1300-pound cows with calves and one 2000-pound bull is used as an example to demonstrate the four steps to rotational grazing. While herbage mass was significantly higher for R fields, even the baseline yields were lower than some previously reported values. Virostek, A. M., B. McIntosh, A. Daniel, M. Webb, and J. D. Plunk. 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. (2019). The C pastures were mowed and dragged as needed to help control weeds and manure build up (approximately twice per growing season). 1). Itâs healthier for the pasture. Jordan, S. A., K. R. Pond, J. C. Burns, D. T. Barnett, and P. A. Evans. 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. 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. Often times rotations are set. 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. There was an association between pasture species frequency counts and treatment (Table 4; P < 0.0001). 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). Extend the grazing season. Carter, R. A., K. H. Treiber, R. J. Geor, L. Douglass, and P. A. Harris. When livestock graze large pastures, they tend to repeatedly graze preferred areas. In a preliminary report comparing grazing systems of warm and cool-season grasses, Daniel et al. Similar stocking rates to the present study were used; however, grazing management strategies varied between studies. Nutritional value of pasture plants for horses. Historical monthly averages for temperature and total precipitation1. In fact, WSC (includes sugars and fructans) and ESC (sugars only) were also highest during these times. 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. 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. Chemical weed control was not performed so as to track natural changes in plant species composition including weed growth. There were no significant differences between treatments for average monthly amount of hay fed or cost of pasture maintenance. Pregraze sward heights were significantly taller in R fields due to the rest period when pastures could regrow. Continuous grazing did not have a large impact on pasture condition until the first full grazing season. Step 1. 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). Compared with C, R had higher proportions of G and W and lower proportions of GW and O. Months with CI gaps between treatments are different at P < 0.05. Other (O) represents all other vegetation (living or dead), plus bare ground, rocks, litter, etc. 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. However, both studies fall in the range of DE values for grass hay and pasture of varying maturity levels reported in the NRC (2007). Regenerative practices helped sequester 2.29 milligrams of â¦ 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. All fields received some supplementation through the early spring and late summer to prevent weight loss, and hay had to be increased during a period of very low rainfall (see Tables 2 and 3 for monthly weather and historical averages) in the midsummer when pastures became dormant. Therefore, it is possible that the nutritional analysis of our randomly selected samples did not accurately represent the plants selected by the horses. 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.) 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. By summerâs end our ladies made it clear that grass was great, but our many trees fit their browsing desires more nicely. 1). Plumb et al. Black lines indicate permanent fencing and white lines indicate temporary electric tape fencing separating rotational fields. Therefore, some months did not have all four sections measured, and the measures for each section were not always performed on the same day. 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. Dividing up a pasture into paddocks to prevent overgrazing goes back to the earliest agr Our hypothesis was that the rotational grazing systems would result in increased horse condition; improved pasture yield and quality; and reduced overall maintenance costs. 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). Excluding winter rest periods, the C horses were fed a total of 4,657.6 Â± 299 kg hay and R horses were fed a total of 5,392 Â± 1,260 kg hay. These bunch grasses are less tolerant of the frequent, close grazing observed in C pastures. Kenny, L. B., D. Ward, M. G. Robson, and C. A. Williams. 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. This was opposite of the expected outcome and an interesting finding given the greater DE of the forage in the rotational pastures. Months with CI gaps between treatments are different at P < 0.05. Change ), You are commenting using your Twitter account. Clippings were compiled, and one sample from each of the four fields was submitted for analysis each month. 5) had a significant effect of treatment (P < 0.0001) with R being greater (11.8 Â± 0.1 cm tall; 1,513.0 Â± 41.2 kg/ha) than C pastures (6.9 Â± 0.1 cm tall; 780.6 Â± 34.7 kg/ha). Â© The Author(s) 2020. 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. Horse BW, BCS, and percent body fat (FAT) were measured monthly to determine the effect of grazing system on horse health. Pastoral and Veterinary Institute Hamilton. 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. The C horses were fed 597 Â± 34.1 kg and R horses were fed 659 Â± 34.1 kg of hay per month on average during the months where hay was offered for the entire study duration. 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. 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. ( Log Out / Months with CI gaps between treatments are different at P < 0.0001. However, continuous grazing is a land extensive system, and low production of gain per hectare makes it inefficient. However, when only considering the grazing months the average monthly cost was $30.30 Â± 5.83 and $32.78 Â± 4.82 for C and R pastures, respectively. 6A) and TC (Fig. 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. Unhealthy Goat Grazing Led to a Health Crisis. However, winter grazing exclusion was practiced in R pastures when forage was not actively growing. 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. Samples were collected monthly between 0800 and 1000. (2011) of 78 Â± 3% and 80 Â± 2% (years 1 and 2, respectively), which are still acceptable by the 70% rule. 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). 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. None declared. Mean prevalence of the planted plant species category by treatment (continuous [C] or rotational [R] grazing)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. 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. 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). The 2R stress lot has gates opening into each rotational field. Henneke, D. R., G. D. Potter, J. L. Kreider, and B. F. Yeates. 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. Alpha level was set at 0.05. Although there are a couple cons i think that rotational grazing is very beneficial and well worth a try. 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. Slow Rotational Grazing: 2 or more pastures with moves from every 2 weeks to every few months. 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. Four grazing areas (two replicates of each grazing system) were established with fencing to be as equal in size as possible (Table 1). Body fat percentage for horses within each treatment (continuous grazing system, C, n = 6 and rotational grazing system, R, n = 6). Fleurance et al. Virginia Polytechnic Inst. Rotational grazing with the correct stocking rate will maintain adequate stubble height and carbohydrate reserves after grazing to maximize forage regrowth. 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. Herbage mass within each treatment (continuous grazing system = C and rotational grazing system = R). This generally requires very conservative stocking rates. Each paddock must provide all the needs of the livestock, such as food, water and sometimes shade and shelter. The new peer-reviewed study looks at the multi-species rotational grazing done on the ranch and found that White Oakâs approach reduced net greenhouse gas emissions of the grazing system by 80 percent. 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).

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. Pregraze height values reported by Burk et al. It is important to note that June 2015 was one of the months with over 50% higher precipitation than the historical average. 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. Webb et al. The C pastures contained temporary run-in shelters, water sources, and hay feeders. 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. 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). Burk, A. O., N. M. Fiorellino, T. A. Shellem, M. E. Dwyer, L. R. Vough, and E. Dengler. (1984) also observed large decreases in cover extending up to 61 m away from a water source when used by horses and/or cattle. Grazing Periods:Grazing Periods: 7 7 -- 14days14days Rest Periods: 20 Rest Periods: 20 ââ 40 days40 days Stock density: 5000 Stock density: 5000 ââ 10,000 lbs./ac10,000 lbs./ac Utilization: 30 Utilization: 30 ââ 45%45% Higher degree of selectivity Rotational Grazing Spot grazing still a problem 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. Similar to above for VC, this corresponds to a month that fell directly after poor precipitation compared with historical averages. 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. While the forage quality was high in April, herbage mass and sward height were quite low at that time and R horses did not graze until early June each season. Digestible energy, acid detergent fiber, and calcium were higher in R vs. C pastures; however, crude protein was lower in R vs. C pastures. (2015) were reported for entire grazing seasons rather than monthly. 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. However, the fact that the flock was moved from one pasture to another does not constitute rotational grazing. On our farm, I like to utilize pasture-based systems for our animals that steward the land well and make my life easier. Grazing pressure is adjusted by adding or subtracting animals or temporarily fencing off areas for hay harvest. The first monthly samples were collected in the first week of September 2014 following one full month of grazing. (2011) found that in comparison to continuous grazing, âmulti-paddockâ (rotational) grazing had a higher proportion of tall grasses to short grasses and forbs. Something that many people in the cattle industry are promoting is rotational grazing. While not particularly attractive, this poses no health concern to the horse. 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. Rotational grazing also has the potential to reduce machinery cost, fuel, supplemental feeding and the amount of forage wasted. Olson-Rutz, K. M., C. B. Marlow, K. Hansen, L. C. Gagnon, and R. J. Rossi. Williams, C. A., L. B. Kenny, and A. O. Burk. 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. Foulk, D. L., R. C. Mickel, E. A. Chamberlain, M. Margentino, and M. Westendorf. The results of this study showed that winter rest alone was not sufficient to mitigate the effects of overgrazing in C pastures. Rotational grazing like most things has its pros and cons. Sward height within each treatment (continuous grazing system = C and rotational grazing system = R). However, neither of these studies utilized replicated pastures. Forage samples collected from C pastures were frequently clipped at ground level, where the prostrate legume common white clover (Trifolium repens) would be found. 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. There were also 2 mo that were well above (more than 50% greater) historical average precipitation. And thatâs exactly what I did when I designed this pastured pigs rotational grazing system. The cost of maintenance on each system was compared by recording the number of times of each pasture unit mowed and dragged. By Kenzi Knapp. 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.

Published by Oxford University Press on behalf of the American Society of Animal Science. 1Analyses were performed by Dairy One DHIA Forage Testing Laboratory, Ithaca, NY. 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. (2011) did find increased horse BW and BCS in a rotational grazing system; however, there was no continuous grazing data to compare. 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.

Rotational grazing also can increase the amount of forage har-vested per acre over continuous grazing by as much as 2 tons dry matter per acre. aâdMonths within columns with a similar superscript are not significantly different (P < 0.05). Horses were fed similar amounts of hay throughout the study. 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. 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). 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. Many graziers use temporary electric fence systems to manage the size of the paddock. Continuously grazed horses had access to early spring pasture (albeit overgrazed and minimal) and required less hay while R horses were still confined until forage reached an appropriate height to graze (15.2 cm). Rotational grazing allows you to graze other livestock on a piece of land. 2Chi-square (3 df, n = 9,600) = 184.6, P < 0.0001. 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 horsesâ requirements was harvested for hay (Burk et al., 2011). However, there were no differences in supplemental hay fed or maintenance costs between the grazing systems. 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. Proponents call it farming grass. Another theory was that the forage sampling height could have contributed to more clover included in the C samples. 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. Another plant of note was buckhorn plantain, Plantago lanceolata, which was abundant in the R pastures. There are also differences by month for DE, ADF, NDF, CP, WSC, ESC, P (P < 0.0001), and Ca (P = 0.0009) when treatments were combined (Table 6). Plant nutrient content data were evaluated using repeated-measures ANCOVA, blocking by field, and utilizing the seasonal covariate month. 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, Olson-Rutz et al. Rotational grazing also has the potential to reduce machinery cost, fuel, supplemental feeding and the amount of forage wasted. (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. The study started in August and ended in November, not all months were sampled the same number of times. Nutrient composition of pastures (DM basis) in the rotational and continuous grazing systems combined for each month across the study duration1. That's a mouthful. The 3R stress lot connects to a laneway with openings into each rotational field. 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. Hubbard, R. K., G. L. Newton, and G. M. Hill. The overall field composition by treatment (continuous [C] or rotational [R] grazing)1. Horses in the C systems were offered hay at 2% BW per day when available pasture forage was low. Shifts in species composition were seen between treatments and months. Vegetative cover and TC may be used interchangeably in the literature, but in general 70% or higher VC is recommended to minimize soil erosion (Costin, 1980). For FAT, horses were lowest in January, February, March, and April, again during both winter seasons. The R horses were mostly confined for the winter starting in November.
