Aguiar and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In the first experiment, forage samples (n = 39) were collected during 4 years (2006 - 2009) from pastures grazed by Santa Gertrudis cattle at the King Ranch, TX. The in vitro gas production technique (IVGP) was performed to understand the pattern of fermentation parameters of the forage and obtain fractional digestion rate (kd) values to predict total digestible nutrients (TDN). The best nonlinear model to describe the IVGP values of the forages was the two-pool logistic equation. The passage rate (kp) of 4%/h was used. The kp predicted by the Large Nutrient Ruminant System (LNRS) model was 3.66%/h. The average TDN was 55.9% compared to 53.8% using a theoretical equation. In the second experiment, Brahman bulls (n = 16) grazed Coastal bermudagrass pastures [Cynodon dactylon (L.) Pers.] and stocked at a moderate to low grazing pressure. Three periods of fecal collections were made within each period. Bulls were individually fed at 0700 and 1900 h of 400 g of corn gluten pellets containing C32 n-alkanes. Each period was divided in 2 sub periods in which fecal samples were collected 4 times a day (0700, 1100, 1500 and 1900 h). N-alkanes in the forage and feces were determined using gas chromatography. In the third experiment, four methods were used to estimate dry matter intake (DMI): C31 or C33 with or without adjustment for forage C32 (C31_0 and C33_0, respectively). There was a difference between morning (0700 and 1100 h) and afternoon fecal collections (1500 and 1900 h) on the predicted DMI using C31 (P = 0.0010), C33 (P = 0.0001), C31_0 (P = 0.0010), or C33_0 (P

Available in PDF, EPUB and Kindle. Book excerpt: Forages: The Science of Grassland Agriculture, 7th Edition, Volume II will extensively evaluate the current knowledge and information on forage agriculture. Chapters written by leading researchers and authorities in grassland agriculture are aggregated under section themes, each one representing a major topic within grassland science and agriculture. This 7th edition will include two new additional chapters covering all aspects of forage physiology in three separate chapters, instead of one in previous editions. Chapters will be updated throughout to include new information that has developed since the last edition. This new edition of the classic reference serves as a comprehensive supplement to An Introduction to Grassland Agriculture, Volume I.

Available in PDF, EPUB and Kindle. Book excerpt: The present study describes experiments aimed at manipulating and evaluating the nutritive value of tropical pastures for grazing cattle. Before commencing experiments with grazing cattle, an experiment was conducted with sheep to determine whether the digestion of mature tropical grass forage varied appreciably from that expected from temperate grass of similar composition. Results from this experiment indicated that despite the low intake and digestibility of mature tropical grass, the digestible fraction of this forage behaved in ways predicted from published data obtained with temperate species. It was concluded that principles of rumen function and ruminant nutrition established with temperate forage species could validly be applied to tropical forage species. The subsequent experiment was aimed at avaluating the effects of superphosphate fertiliser on the botanical and chemical composition and nutritive value of the diet selected by cattle grazing Stylosanthes-native grass pastures. The data obtained in this experiment showed that superphosphate fertiliser improved the nutritive value of the diet selected. Animals grazing fertilised pastures had a significantly higher organic matter intake than those grazing unfertilised pastures during the wet and dry seasons but not during the wet-dry transition. This lower consumption with unfertilised pastures during the wet and dry seasons was associated with lower digestibility of the diet selected and possibly also with lower phosphorus content during the wet season. There was no evidence that higher organic matter intake observed for fertilised pastures was associated with a greater production of legume nor with the ingestion of a greater proportion of legume in total diet. It appears that the amount of legume in the diet was mainly determined by the time of the year and by the proportion of legume available in the pasture. Three experiments were conducted to evaluate the use of monensin sodium for manipulating rumen fermentation on the nutritive value of native pasture. The first experiment studied the effect of monensin on liveweight change of steers grazing a native pasture and the second examined this effect on the nutritive value of the forage selected during the wet and dry seasons, while the third used penned animals to study the effect of monensin on the nutritive value and utilisation of native pasture hay with and without nitrogen supplements. Results from these experiments indicated that monensin was efficient in changing the rumen fermentation patterns by increasing the production of propionic acid and reducing acetic and butyric acids. However, no beneficial effects on intake and liveweight gain of grazing animals was observed by the use of monensin during the wet or dry season. Although supplementation of the low quality hay with urea plus formaldehyde-treated casein produced an increase in the digestible organic matter intake (largely by improving both intake and digestibility), no benefit for the animal was achieved by the use of monensin. Comparisons made between predicted and observed liveweight gain of cattle grazing tropical pastures suggest that liveweight gain could accurately predicted from digestible organic matter intake by the use of tables presented by the Commonwealth Agricultural Bureaux - CAB (1980). However, estimates of feed consumption from formulae presented by the CAB underestimated the observed intakes by 25% during the wet season. There is, therefore, an urgent need for the development of equations that would allow the estimation of the digestible organic matter intake. A relationship between organic matter digestibility and digestible organic matter intake is proposed and its limitations are discussed. Although it is clear that much research is needed to elucidate problems of nutrition of cattle grazing tropical pastures, the results from this investigation suggest that the CAB system does provide a useful framework to base the development of system for livestock feeding for tropical as well as for temperate Australia.

Download or read book Forage in Ruminant Nutrition written by Dennis Minson and published by Elsevier. This book was released on 2012-12-02 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forage in Ruminant Nutrition is the 12th text in a series of books about animal feeing and nutrition. The series is intended to keep readers updated on the developments occurring in these fields. As it is apparent that ruminant animals are important throughout the world because of the meat and milk they produce, knowledge about the feeds available to ruminants must also be considered for increased production and efficiency. This text provides information that readers will find considerably invaluable about forage feeds, such as grass, legumes, hay, and straw. The book is composed of 16 chapters that feature the following concepts of ruminant forage feeding: • composition of ruminant products and the nutrients required for maintenance and reproduction; • energy and nutrient available in forage: calcium, phosphorus, magnesium, sodium, copper, iodine, zinc, manganese, selenium, and cobalt; • intake of forage by housed ruminants; • grazing; • forage digestibility; • protein in ruminant nutrition; • protein and other nutrient deficiencies. This volume will be an invaluable reference for students and professionals in agricultural chemistry and grassland and animal husbandry researches.
