Book Synopsis The Development, Nutrition, and Management of the Young Calf by : Carl L. Davis
Download or read book The Development, Nutrition, and Management of the Young Calf written by Carl L. Davis and published by Iowa State Press. This book was released on 1998-01-01 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: An indispensable resource for the dairy farmer or veterinarian, the researcher, teacher, or advanced student, this book puts the cutting–edge science of raising dairy calves into an accessible, usable form. Geared to those with a basic understanding of principles of animal nutrition and husbandry, the volume gives a comprehensive account of all aspects of calf rearing, from the rudiments of anatomy and development through the practicalities of feeding and housing. The Development, Nutrition and Management of the Young Calf begins with an overview of how the calf′s digestive system develops, highlighting the period of transition from preruminant to ruminant digestion. Here the authors provide information essential to understanding nutritional needs and restrictions during the liquid–feeding phase in the young calf as well as those factors that govern the development of a functional rumen. Major emphasis is given to the energy and protein requirements of the young calf, with attention to the effects of environmental temperature on energy requirements. The authors also review the adequacy of current National Research Council recommendations on the energy and protein requirements of young calves. They discuss the management, nutrition, and care of the pregnant cow as well as calving management necessary to deliver a healthy calf. Other topics include liquid–feeding systems, formulation and use of milk replacers and starter feeds, the weaning process, housing principles, and the interactions of nutrition and disease

Book Synopsis Biostatistical Analysis of Factors Influencing Lactation Performance of Range Cows and Weaning Weights of Their Calves [microform] by : Sarah Louise Butson

This book was released on 1981 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was carried out to examine trends in lactation performance and factors influencing milk traits and calf weaning weight among range beef cattle. Cows representing four beef and dairy-beef breeds and lines from the University of Alberta beef herds ranging in age from 2 to 10 years of age were used in the study. June and September measurements of milk and constituent percentages were taken on 206 and 242 cows in 1976 and 1977 respectively. Age and breed of dam, and age and sex of calf were recorded. Other variables examined were cow weight changes during gestation and lactation and birthweights, weaning weights and preweaning ADG of their calves. Milk variables and calf weaning weights were the traits studied. In Chapter I the lactation performance of the four breed groups of dams was examined. Results indicated that crossbred cows with dairy breed ancestry yielded more milk and were more persistent than a purebred traditional beef breed. Trends between breeds for constituent percentage production were less noticeable although the dairy crossbreds tended to produce less butterfat% than the purebreds. In Chapter II factors influencing milk and constituent yields were investigated using the multiple regression technique in Chapter II. Stepwise regressions involving age and breed of dam accounted for between 34.0% and 44.0% of the variance in any of the milk or constituent yields. Full and restricted regression models allowed the introduction of independent variables after adjusting for age and breed of dam effects. Calf preweaning ADG showed a high association with milk yield variables. Other factors such as calf birthweight and cow weight changes however did not account for a significant proportion of the variance in any one milk or constituent yield variable. Because associations and correlations between milk yield and calf ADG were significant but only moderately high, all factors influencing weaning weights of range calves were examined in Chapter III. Regression analysis indicated that age and breed of dam effects accounted for an average of 47% of the variance in calf weaning weight. When age and breed of dam were not considered, milk or constituent yields accounted for approximately 40% of weaning weight variance. However, milk variables still accounted for up to 10% of the variance after accounting for the effects of age and breed of dam. Calf birthweight and cow weight changes had minor effects on calf weaning weight. As a significant proportion of the variance in weaning weight was accounted for by milk variables, which in turn are largely a reflection of the breed of dam, it was concluded that selection for increased lactation performance and the introduction of dairy breeds into the breeding program of a beef herd can effect meaningful increases the weights of calves weaned.

Book Synopsis Breeding for Robustness in Cattle by : Marija Klopčič
Download or read book Breeding for Robustness in Cattle written by Marija Klopčič and published by Brill Wageningen Academic. This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past decade has revealed unfavourable trends in e.g. fertility, udder health and locomotion in some major dairy cattle breeds due to a large increase in production and insufficient consideration of functional traits in the breeding goals. Such unfavourable trends in some functional traits increase costs. Additionally, the enlargement of herds leads to less available labour time per individual cow. This asks for cows that are easy to handle. At the same time, society is demanding a higher welfare standard of animals. These contradicting developments have increased the desire for so called more robust animals. Robustness can be defined as 'the ability to maintain homeostasis in commonly accepted and sustainable herds of the near future'; or 'the ability of the cow to function well in the environment she lives in as well as in a wide range of climates and production systems'. This book contains a series of articles (26) dealing with the concept of robustness, including aspects like evolution, genetics, environment, animal health and welfare, and integrity. Besides the major functional traits also the links to energy balance, hot climatic conditions, and the attitude and input of stakeholders towards robustness as part of the breeding program are discussed. This book is the first attempt to summarise the available knowledge concerning this topic in cattle, making this book unique. The contributions are from authors of 16 countries from all over the world. However, the focus is presently on farm animal level, while in future robustness of the whole production system may also require additional attention.

Book Synopsis Nutrient Requirements of Beef Cattle by : Subcommittee on Beef Cattle Nutrition
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.
