Download or read book Validation of a Novel Approach to Predict Total Tract NDF Digestibility in Dairy Cattle Using an in Vitro Assay written by and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three experiments were conducted to compare estimates of fiber digestion predicted from in vitro fiber digestibility analysis of diets to fiber digestion measured in lactating cows fed the same diets. In the first experiment, an in vivo study was performed to validate an in vitro procedure that predicts rate of fiber digestion and total tract fiber digestibility (TTNDFD). Two corn silages differed in fiber digestibility (high and low) were used in this trial. Two diets were formulated and analyzed using the in vitro assay to predict the TTNDFD and rumen potentially digestible NDF (pdNDF) and rate of digestion (kd). Similar diets were fed to eight ruminally cannulated multiparous dairy cows at restricted intake (approximately 90% of ad libitum intake) and at ad libitum intake. The in vitro TTNDFD test predicted total tract NDF digestibility of diets similar to digestibility observed in vivo, but for Low fiber digestibility corn silage (LFDCS) diets, this test underestimated the digestibility compared to in vivo. These results suggest that the in vitro TTNDFD model could be used to predict rate of fiber digestion and NDF digestibility for dairy cows. In a second trial, the effect of altering ratios of corn silage and alfalfa silage on fiber digestion were evaluated. The two forages had similar NDF composition, but fiber in the corn silage contained less indigestible NDF (iNDF) than the alfalfa silage. Four diets were formulated containing different DM proportions of alfalfa and corn silage, and fed to eight ruminally-cannulated dairy cows. Total tract fiber digestibility and fiber digestion kinetic parameters observed in vivo were compared to the values predicted by the in vitro assay and model. Total tract NDF digestibility coefficients were similar for the in vitro and in vivo method. As the proportion of dietary alfalfa increased, the digestibility of NDF increased. The rate of digestion of pdNDF predicted from the in vitro assay was also similar to what was observed. Results suggest that the in vitro TTNDFD model could be used to predict rate of fiber digestion and NDF digestibility for lactating dairy cattle. The objective of the third experiment was to validate an in vitro test to predict total tract fiber digestibility in lactating cows by an in vitro assay. Twenty-one diets fed to lactating cows in seven different studies were used for this trial. Fiber digestibility measured in vivo was similar to values obtained from the in vitro assay. This in vitro approach can predict values of fiber digestibility similar to values directly measured in vivo.

Download or read book Nutrient Requirements of Beef Cattle written by Subcommittee on Beef Cattle Nutrition and published by National Academies Press. This book was released on 2000-05-16 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: As members of the public becomes more concious of the food they consume and its content, higher standards are expected in the preparation of such food. The updated seventh edition of Nutrient Requirements of Beef Cattle explores the impact of cattle's biological, production, and environmental diversities, as well as variations on nutrient utilization and requirements. More enhanced than previous editions, this edition expands on the descriptions of cattle and their nutritional requirements taking management and environmental conditions into consideration. The book clearly communicates the current state of beef cattle nutrient requirements and animal variation by visually presenting related data via computer-generated models. Nutrient Requirements of Beef Cattle expounds on the effects of beef cattle body condition on the state of compensatory growth, takes an in-depth look at the variations in cattle type, and documents the important effects of the environment and stress on food intake. This volume also uses new data on the development of a fetus during pregnancy to prescribe nutrient requirements of gestating cattle more precisely. By focusing on factors such as product quality and environmental awareness, Nutrient Requirements of Beef Cattle presents standards and advisements for acceptable nutrients in a complete and conventional manner that promotes a more practical understanding and application.
Download or read book Nutrient Requirements of Dairy Cattle written by National Research Council and published by National Academies Press. This book was released on 2001-02-09 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: This widely used reference has been updated and revamped to reflect the changing face of the dairy industry. New features allow users to pinpoint nutrient requirements more accurately for individual animals. The committee also provides guidance on how nutrient analysis of feed ingredients, insights into nutrient utilization by the animal, and formulation of diets to reduce environmental impacts can be applied to productive management decisions. The book includes a user-friendly computer program on a compact disk, accompanied by extensive context-sensitive "Help" options, to simulate the dynamic state of animals. The committee addresses important issues unique to dairy science-the dry or transition cow, udder edema, milk fever, low-fat milk, calf dehydration, and more. The also volume covers dry matter intake, including how to predict feed intake. It addresses the management of lactating dairy cows, utilization of fat in calf and lactation diets, and calf and heifer replacement nutrition. In addition, the many useful tables include updated nutrient composition for commonly used feedstuffs.
