Download or read book Grazing behavior and forage selectivity of cattle and sheep grazing alone or together on swards differing in plant species diversity written by Mario Cuchillo Hilario and published by Cuvillier Verlag. This book was released on 2012-02-23 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Grassland composition and animal species may modify the grazing efficiency and ingestive behavior at pasture. However, precise knowledge on potential interactions between sward diversity and co-grazing is not available. Thus, a trial was conducted to evaluate the behavior patterns and forage selectivity of cattle and sheep grazing alone or together on grass swards differing in botanical composition. The experiment was carried out on mesotrophic permanent grassland in the Solling Uplands of Lower Saxony, Germany from May to September of 2009 and 2010. Species diversity of paddocks was manipulated by the use of herbicides resulting in grass-dominated swards (7 species per 9 m2) in contrast to untreated diverse swards (14 species per 9 m2) with grasses, forbs and legumes. Each sward type was combined with three grazing treatments: C= cattle mono-grazing; S= sheep mono-grazing and CS= cattle and sheep cograzing. The six treatments were set up on paddocks of 0.5 ha each, replicated three times in blocks that were grazed rotationally. The main behavior patterns (grazing, walking, and ruminating) were recorded by conducting scan sampling every ten minutes from six a.m. to ten p.m. Secondary patterns (bites per minute, steps per minute, and bites per step) were obtained per core animal and observation day. Intake choices of Dactylis glomerata, Festuca pratensis, Lolium perenne, Phleum pratense, Taraxacum officinale, and Trifolium repens were obtained as follows: species were visually assessed in five 0.5 m2 subplots per plot immediately before and after a period of three days grazing on a plot. Jacobs’ selection index (JSI) was used to quantify the intake preference for single target species in relation to their proportion in the sward. JSI = ci – ai / ci + ai - 2ciai; where ci= % forage in the diet and ai = % forage in the pasture. Here, ai was evaluated by the difference between the percentage mass of each species before and after three days of grazing. For behavior patterns, there were important differences between sheep and cattle. Cattle varied their time budget and grazing behavior depending on the presence of sheep. However, plant diversity had no effect on cattle behavior. For sheep behavior, plant diversity rather than mono or co-grazing management was the determinant factor. Cattle mono-grazing on diverse swards spent more time grazing at lower ingestive rates. P. pratense was the most preferred forage species (JSI=0.62). L. perenne, T. officinale and T. repens were also highly preferred regardless of sward composition or type of grazer (JSI = 0.47, 0.32 and 0.27, respetively). Co-grazing facilitated a more homogeneous consumption of the main forage species. Co-grazing might have the potential to better maintain grassland biodiversity.

Download or read book Horse Pasture Management written by Paul H. Sharpe and published by Academic Press. This book was released on 2018-11-09 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: Horse Pasture Management begins with coverage of the structure, function and nutritional value of plants, continuing into identification of pasture plants. Management of soil and plants in a pasture is covered next, followed by horse grazing behavior, feed choices of horses, management of grazing horses, and how to calculate how many horses should be grazing relative to land size. Management of hay and silage are included, since year-round grazing is not possible on many horse farms. A number of chapters deal with interactions of a horse farm with the environment and other living things. As an aid in good pasture management, one chapter explains construction and use of fencing and watering systems. Contributions are rounded out with a chapter explaining how the University of Kentucky helps horse farm managers develop their pasture management programs. - The purpose of the book is to help people provide a better life for horses - Provides the basic principles of pasture management for those involved in equine-related fields and study - Covers a variety of strategies for managing the behavior, grouping, environmental, and feeding needs of grazing horses to ensure high levels of welfare and health - Includes information on environmental best practices, plant and soil assessment, and wildlife concerns - Explains pasture-related diseases and toxic plants to be avoided - Includes links to useful resources and existing extension programs

Download or read book Grass Productivity An Introduction to Rational Grazing written by Dr. Robert C. Worstell and published by Lulu.com. This book was released on 2015-01-13 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: SIMPLE questions often help us to understand problems better; and I think it indispensable, at the beginning of this work, to ask a question which appears simple in the extreme: "What is grazing?" The answer is generally as follows: "Causing grass to be eaten by an animal." That is correct! But here is another answer which, to my mind, is more realistic: "Causing the grass and the animal to meet." Since this book is almost exclusively concerned with grazing by cattle, I propose the following definition to the reader, requesting him to allow it to become well impressed upon his mind: Grazing is the meeting of cow and grass. It is by satisfying as far as possible the demands of both parties that we will arrive at a rational grazing, which will provide us with maximum productivity on the part of the grass while at the same time allowing the cow to give optimum performance.

Download or read book Grazing Behavior and Distribution of Cattle on Mountain Rangelands written by Robert Lee Gillen and published by . This book was released on 1982 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several aspects of cattle grazing behavior and distribution were studied on mountain rangeland dominated by ponderosa pine- Douglas fir, mixed conifer, and white fir forest communities in northeastern Oregon. The association between upland distribution, determined by forage utilization and by direct cattle observation, and several habitat factors was studied through correlation and regression analysis. Cattle use of small riparian meadows was monitored by periodic utilization sampling and time-lapse photography. Individual cattle were marked to study the occurrence of home range behavior. Riparian meadows were the most heavily used plant communities averaging about 75% forage utilization over all sites and years. Utilization levels were similar under continuous grazing and the early and late grazing periods of a two pasture deferred-rotation system. Late grazing increased the frequency of cattle presence on the riparian meadows as compared to early grazing. Large quantities of forage, a dependable source of water, and gentle topography combined to make riparian meadows the major influence on cattle distribution. Afternoon temperature and relative humidity were similar in riparian meadow versus upland plant communities. Upland forage use averaged 8-12% and the highest estimated utilization on a single site was 36%. When available, clearcut forest sites were the most highly preferred upland plant community, especially when introduced pasture grasses were present. Late grazing decreased use on the clearcut sites by 1/3 because of the advanced maturity of the herbage. Cattle use appeared to shift to the riparian meadows in this situation. A large percentage of cattle were observed within the ponderosa pine-Douglas fir communities although these were not preferred range areas. The grassland, mixed conifer forest, and white fir forest communities were all lightly used by cattle. Slope gradient was the physical habitat factor most consistently associated with cattle distribution. SAlt distribution also appeared to be important. Water distribution did not limit cattle grazing behavior. Cattle restricted their activities to home ranges averaging 343 ha. Home range size was similar between purebred and crossbred cattle.

Download or read book Responses of Plant Communities to Grazing in the Southwestern United States written by Daniel G. Milchunas and published by . This book was released on 2006 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Grazing by wild and domestic mammals can have small to large effects on plant communities, depending on characteristics of the particular community and of the type and intensity of grazing. The broad objective of this report was to extensively review literature on the effects of grazing on 25 plant communities of the southwestern U.S. in terms of plant species composition, aboveground primary productivity, and root and soil attributes. Livestock grazing management and grazing systems are assessed, as are effects of small and large native mammals and feral species, when data are available. Emphasis is placed on the evolutionary history of grazing and productivity of the particular communities as determinants of response. After reviewing available studies for each community type, we compare changes in species composition with grazing among community types. Comparisons are also made between southwestern communities with a relatively short history of grazing and communities of the adjacent Great Plains with a long evolutionary history of grazing. Evidence for grazing as a factor in shifts from grasslands to shrublands is considered. An appendix outlines a new community classification system, which is followed in describing grazing impacts in prior sections.
