Book Description
he study was conducted to get substanitial information on nulrienls utilisation towards carcass development in growing male murrah buffalo calves icept on complete diets. The study was conducted in 3 phases namely In vitro degradability of feedsat different levels of crude protein, nutrient utilisation in buffalo calves at different levesl of crude protein R at 3 age groups and growth body composition and feed efficiency of bufalo calves at different levels of crude protein & at two age groups. Results have shown that ammonia production increased on increasing the CP level in the substrate but processing the substrate to pellets reduced the in vitro concentration of ammonia and increased the VFA production. Through digestabilities of crude protein increased on increasing the CP in ration but : dttrogeh retention was more on 10 : CP. Simullaraneousks The efficiency for utilising digeesse d N towards retention was also higher in low CP ration, since urinary-N followed the trend of ditroges intake . Body weight gain was ot affected by the levels of dietery CP and age of the animal. The DCP required per 10 kg gain was lower in case of 10 : CP ration. Levels of CP did not affect DM conversion to growth. Body water increased white fat decreased with increase of CP level in thefeed. Dietary levels of CP did not affect dressing : and not caracass weight but these characters were higher on higher age groups. The yield of MOSC of the offals (:) was higher on lower age groups but unaffected due to dietary protein level. The separate lean (:) was more and separate fat (:) less on 14 and 18 : CP level. Fat : age groups. Meat quality characters were not influenied by dietary crude protein levels.

Book Description
In the years since the third edition of this indispensable reference was published, a great deal has been learned about the nutritional requirements of common laboratory species: rat, mouse, guinea pig, hamster, gerbil, and vole. The Fourth Revised Edition presents the current expert understanding of the lipid, carbohydrate, protein, mineral, vitamin, and other nutritional needs of these animals. The extensive use of tables provides easy access to a wealth of comprehensive data and resource information. The volume also provides an expanded background discussion of general dietary considerations. In addition to a more user-friendly organization, new features in this edition include: A significantly expanded section on dietary requirements for rats, reporting substantial new findings. A new section on nutrients that are not required but that may produce beneficial results. New information on growth and reproductive performance among the most commonly used strains of rats and mice and on several hamster species. An expanded discussion of diet formulation and preparationâ€"including sample diets of both purified and natural ingredients. New information on mineral deficiency and toxicity, including warning signs. This authoritative resource will be important to researchers, laboratory technicians, and manufacturers of laboratory animal feed.

Book Description
Feed Efficiency in the Beef Industry provides a thorough and concise overview of feed efficiency in beef cattle. It frames the great importance of feed efficiency to the industry and details the latest findings of the many scientific disciplines that intersect and aim to improve efficient and sustainable production of nutritious beef. The vast majority of production costs are directly tied to feed. With increased demand for grains to feed a rapidly increasing world population and to supply a new demand for alternative fuels, feed costs continue to increase. In recent years, the negative environmental impacts of inefficient feeding have also been realized; as such feed efficiency is an important factor in both economic viability and environmental sustainability of cattle production. Feed Efficiency in the Beef Industry covers a broad range of topics ranging from economic evaluation of feed efficiency to the physiological and genetic bases of efficient conversion of feed to high quality beef. Chapters also look at how a fuller understanding of feed efficiency is leading to new selective breeding efforts to develop more efficient cattle. With wide-ranging coverage from leading international researchers, Feed Efficiency will be a valuable resource for producers who wish to understand the complexities, challenges, and opportunities to reduce their cost of production, for students studying the topic and for researchers and professionals working in the beef industry.
