Intake Characteristics And Performance Of Contrasting Grass Varieties Continuously Stocked With Sheep, R. J. Orr, J. E. Cook, R. A. Champion, A. J. Rook
Intake Characteristics And Performance Of Contrasting Grass Varieties Continuously Stocked With Sheep, R. J. Orr, J. E. Cook, R. A. Champion, A. J. Rook
IGC Proceedings (1993-2023)
Fifteen intermediate-heading perennial ryegrass (Lolium perenne) varieties were grazed by sheep under continuous variable stocking management. Mean daily grass dry matter intake per ewe was positively correlated with liveweight gain per ewe (r = 0.63) and per ha (r = 0.58) over an 8-month grazing season. Daily intake was not correlated with grazing time (r = 0.12) but was positively correlated with instantaneous dry matter intake rate (r = 0.75). Breeding varieties with high intake rate characteristics should allow increases in the contribution of grazed grass to grassland-based livestock farming. There is now a …
Intake And Digestibility Of Black Locust Foliage Fed To Growing Goat Wethers, L. J. Unruh, J-M. Luginbuhl, J. P. Mueller
Intake And Digestibility Of Black Locust Foliage Fed To Growing Goat Wethers, L. J. Unruh, J-M. Luginbuhl, J. P. Mueller
IGC Proceedings (1993-2023)
Leaves of Black locust (BL, Robinia pseudoacacia), a native southeastern United States tree species known to contain substantial levels of condensed tannins, were fed to 16, four month old (20.4 kg body weight [BW]) Boer wether goats (Capra hircus hircus) to determine their effects on intake and digestibility. Four diets were stall fed in a randomized complete block design (RCBD) with four replications. Diets included: (1) 100% eastern gamagrass (EGH; Tripsacum dactyloides) hay; (2) 70% EGH and 30% mixture of ground corn (GC; Zea mays) and soybean (Glycine max) meal (SBM); (3) 75% …
Intake And Qualitative Aspects Of Guinea Grass Grazed By Sheep Over Three Different Seasons, Willem A. Van Niekerk
Intake And Qualitative Aspects Of Guinea Grass Grazed By Sheep Over Three Different Seasons, Willem A. Van Niekerk
IGC Proceedings (1993-2023)
The objective of this study was to determine the influence of season on intake by sheep as well as certain selected qualitative characteristics of Panicum maximum (cv Gatton) (Guinea grass) at the mature growing stage. The lower DM content of the spring and summer grass (41.6 and 40.2%) did not hamper DOMI (48.1 and 26.7 W0.75/d), respectively. The N concentration of the spring and summer grass was well within the limit required for optimal rumen microbial production (1.8 - 2.0%). The high cell wall components of the winter grass resulted most probably in a significant lower IVDOM value …

Prediction Of Intake Of Hay Differing In Species And Maturity By Goats, S. W. Coleman, S. P. Hart, T. Sahlu
IGC Proceedings (1993-2023)
Eight species of forage, a cool-season perennial (Festuca arundinacea) and annual grass (Triticum aestivum), four warm-season perennial grasses (Bothriochloa caucasica, B. ischaemum, Cynodon dactylon, and Tripsacum dactyloides), a warm season annual (Digitaria sanguinalis) and a perennial legume (Medicago sativa), were cut at two or three maturities to provide a wide array of quality difference (n=20). Twenty wether goats (Capra hicus) were fed the hays in four different trials using an incomplete block so that each hay was fed to four different goats. Alfalfa produced the highest DM, …
Foraging Behaviour And Intake In Temperate Cultivated Grasslands, S. Prache, J. L. Peyraud
Foraging Behaviour And Intake In Temperate Cultivated Grasslands, S. Prache, J. L. Peyraud
IGC Proceedings (1993-2023)
In temperate areas, grazing provides a large part of the nutrient requirements of ruminants and may be an important form of land use. In Europe, grassland occupies some 150 million hectares, and grazing provides about 60 to 75% of the nutrient requirements of cattle (Wilkins and Vidrih 2000). From the end of the 80’s, agricultural surpluses in Europe have led to production quotas and increased interest in more extensive systems. At the beginning of the 90’s, the emergence of the notion of sustainable agriculture combining economic, social (concerns in dereliction of less-favoured rural areas), and environmental issues (pollution, loss of …
Foraging Strategies On Rangeland: Effects On Intake And Animal Performance, Peter O’Reagain
Foraging Strategies On Rangeland: Effects On Intake And Animal Performance, Peter O’Reagain
IGC Proceedings (1993-2023)
Rangelands exhibit extreme spatial and temporal variability in forage quality and availability. The animals that utilise these rangelands have consequently evolved a range of foraging strategies in an attempt to cope with this variability and maintain nutrient intake. In general, animals respond to and exploit spatial variability at all scales by selecting those items or units which optimise the intake of digestible nutrients and hence animal production. Animals similarly employ a variety of strategies to cope with temporal variability on rangelands. These strategies may include adjusting foraging behaviour and/or exploiting critical resources or resource areas to buffer temporal variability in …

Effects Of Tropical Legume (Stylosanthes Cv. Campo Grande) Silage And Dietary Protein Levels On Animal Performance Of Finishing Beef Cattle, Leandro Diego Da Silva, Odilon G. Pereira, Thiago C. Da Silva, Sebastião De C. Valadares Filho, Karina G. Ribeiro
IGC Proceedings (1993-2023)
Recently, the interest in legume silage for livestock systems has increased in tropical countries (Heinritz et al., 2012) because of the high inclusion of the protein sources in the concentrate used in feedlot diets, like soybean meal. Stylosanthes cv. Campo Grande was developed in Brazil and this cultivar has a good adaptation to tropical conditions, as soils with low fertility and high acidity (Fernandes et al., 2005). Recently, this legume has been indicated for silage making because of its nutritional value and previous results with beef cattle have showed similar performance and digestibility in comparison with corn silage (Souza …

IGC Proceedings (1993-2023)
Leucaena leucocephala is a leguminous tree widely distributed in the tropical regions of the world. In Mexico, it has been incorporated into silvopastoral systems and is highly regarded, owing to its high content of crude protein. Nonetheless, L. leucocephala contains secondary metab-olites, such as mimosine, a non-protein free amino acid, which may induce toxic effects in unadapted ruminants that consume the forage (Hammond 1995). Although Synergistes jonesii, an anaerobic bacterium, has the ability to degrade 3,4-DHP and 2,3-DHP to non-toxic compounds (Allison et al. 1992), in Mexico its presence has not yet been confirmed. Recent work has suggested …

IGC Proceedings (1993-2023)
Leucaena leucocephala is an adapted legume widely distributed in the tropical regions of Mexico. The high crude protein content of leucaena leaves renders it appropriate for ruminant feeding under commercial conditions. However, the foliage contains the non-protein amino acid mimosine, which, if consumed in high amounts, may induce toxicity in animals which have not previously consumed the legume or without microorganisms capable of degrading mimosine and its derivatives 2,3-DHP (dihydroxypyridine) and 3,4-DHP (Hammond 1995, Palmer et al. 2010, Dalzell et al. 2012). Barros-Rodríguez et al. (2012) found that dry matter intake and weight gain were reduced when …

Vegetables are one of the main sources of nitrogen on human diet.Nitrogen content in 30 soil samples and 30 vegetables samples are reported. The results indicate that nitrogen content was low in 33% of soil samples,normal in 50% of the samples, and high in 17% of soil samples. Reportedresults indicate that 47% of vegetables samples had low nitrogen content, 30%of them had normal nitrogen content, and 13% and 10% of them had high andvery high nitrogen content, respectively. Soil nitrogen is also reported asammonium and nitrate, and results indicate that nitrate is the dominant form ofnitrogen. There was a good …
