This book was released on 2006 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Four feedlot trials were conducted to evaluate the effects of dietary vitamin A restriction on marbling and beef fatty acid composition in growing cattle. In Exp. 1 the effects of feeding low vitamin A diets and including roasted soybean in the diet on marbling and fatty acid composition were evaluated. Feeding low vitamin A diets tended to increase marbling without affecting carcass back fat and yield grade. It appeared that low vitamin A diets induced hyperplasia in the intramuscular (i.m.) but not in the subcutaneous (s.c.) depot. Feeding low vitamin A diets did not affect fatty acid composition in muscle. In Exp. 2, the effect of duration of dietary vitamin A restriction on the site of fat deposition in Holstein steers was evaluated. Restricting vitamin A intake for 243 d increased i.m fat percentage without affecting s.c. fat deposition or feedlot performance. Restricting vitamin A intake for 131 d or less appeared to be insufficient to affect the site of fat deposition in Holstein steers. In Exp. 3, Angus-based steers were used to evaluate the effect of low vitamin A diets with high-moisture- or dry- corn on marbling and fatty acid composition. Regardless of the corn type used, feeding low vitamin A diets for 145 d increased marbling and quality grade without affecting yield grade, animal health and performance. The CLA content of adipose tissue was not affected by the treatments. In Exp. 4, a feedlot experiment was conducted to evaluate the effects of dietary vitamin A restriction on marbling and immune status. Feeding low vitamin A diets for 216 d to Angus-based steers did not affect feedlot performance, marbling score and immuno-competency. Taken together these experiments suggest that feeding low vitamin A diets to growing cattle may be an effective strategy to increase marbling without affecting s.c. fat deposition. Animal performance, health and immuno-competency were not affected by vitamin A restriction. Feeding low vitamin A diets did not appear to be an effective strategy to increase CLA in ruminant tissues.

Available in PDF, EPUB and Kindle. Book excerpt: Excess minerals in the diet and water of animals can have an adverse effect on animal health, consumers, and the environment. Preventing unsafe mineral exposure is a fundamental part of animal nutrition and management. At the request of the Food and Drug Administration, the National Academies convened a committee to make recommendations on animal tolerances and toxic dietary levels, updating a 1980 report on mineral tolerance in domestic animals. Based on a review of current scientific data and information, the report sets a "maximum tolerable level" (MTL) for each mineral as it applies to the diets of farm animals, poultry, and fish. The report includes an analysis of the effects of toxic levels in animal diets, and it identifies elements that pose potential human health concerns. The report recommends research that includes a better characterization of animal exposure to minerals through feedstuffs; a better understanding of the relationship between mineral concentrations in feed and water and the levels in consumer products such as meat, milk, and eggs; and more research on the maximum tolerable level of minerals for aquatic and companion animals.

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.
