This book was released on 2018-09-11 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Production of Dairy Cows as Affected by Frequency and Regularity of Milking and Feeding Cows milked twice a day and three times a day for long periods, 217 to 365 days, gave nearly 20 per cent more milk and nearly 21 per cent more butterfat when milked three times a day. The decline in milk yield in the long periods was much greater when the cows were milked twice a day than when they were milked three times a day. The production Of milk by a cow milked once a day declined times as fast as when she was milked twice a day. Cows milked four times and three times a day, in alternate periods of 30 days, following 10 day transitional periods, gave 7 per cent more milk and 6 per cent more butterfat when milked four times a day. The explanation Offered for the greater yield following the more frequent milking is that relief from the pressure of milk within the udder allows secretion to proceed more freely. Changing milkers resulted in an almost negligible decrease in milk production. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

This book was released on 2018-09-11 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Relative Utilization of Energy in Milk Production and Body Increase of Dairy Cows The heat given Off by the annual while in the respiration calo rimeter is removed from the apparatus'in a current Of water, in water vapor, in excreta, and in milk, and the sum Of the heat thus removed correct-cd for the introduction Of feed and water as well as for the man engaged in milking, is the total heat emission. Under the heading radiation, etc., in Table 16 is included all the heat except that removed as latent heat Of water vapor, and in the last column the heat by radiation is expressed in per cent Of the total. This heat emission, however, is not necessarily identical with the total heat production Of the ration fed, but must be corrected for change in live weight Of the animal and for any change in the body temperature. This correction has the effect Of rendering the data representative Of the body in such condition as at the beginning Of the experiment.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Dairy Cattle and Milk Production: Prepared for the Use of Agricultural College Students and Dairy Farmers Milk, with its products, serves as one of the most important sources of food for all highly civilized nations. A large proportion of the best agricultural lands of the world are utilized for its production. Although milk and products of milk have been used to some extent for food as far back as history records, the general use of milk as food has come about only with the development of highly civilized nations. Martiny 1 points out that the native races of America, Africa, and Australia, which have never developed past the stage of barbarism, do not use milk as food. The primitive races of Western Asia and of Europe made use of milk, as have their descendants, and according to this author, to this fact is due in no small degree the great intellectual develop ment of Europe and America.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Roots for the Dairy Cow Four feeding trials were run in which mangels were compared with corn for milk production when fed on the dry-matter basis. As far as possible all other factors were balanced in the two groups, and the single reversal feeding method was used so that the same animals might receive the different rations. Data were kept also on the amount of water consumed from the drinking cups and the amount obtained from the succulent feed.

Available in PDF, EPUB and Kindle. Book excerpt: Proceedings of the European Cooperation in the Field of Scientific and Technical Research (COST 825) Symposium on Mammary Gland Biology, held September 16-18, 1999, in Tours, France. It is difficult to overstate the evolutionary and functional significance of mammary tissue in biology. Substantial progress has been made by researchers in various disciplines, particularly over the last fifteen years, towards realizing the potential of this tissue to yield powerful experimental models for morphogenesis and tissue development; for cellular differentiation; for the biosynthesis and secretion of proteins, lipids, small molecules and inorganic salts; and for the coordination and regulation of these processes. More recently, the possibility of exploiting the secretory epithelial cells of mammary tissue as `cell factories' has become a reality and the recombinant production by lactating animals of an increasing number of proteins, valuable both in the pharmaceutical and `nutraceutical' fields, is in progress or under development. Also in this sphere of agricultural production, genetic as well as nutritional technologies are under investigation and exploitation to optimize milk composition for various end-uses - for instance in food process and manufacture. The possibilities of deriving health benefit from the bioactive properties of some of the minor constituents of milk are emerging to counter the highly-publicized negative health impact of excessive consumption of saturated animal fats. In human nutrition and medicine, the mammary gland is both a source of nutrition to the neonate and a potential health threat to the adult female - breast cancer remains the major single cause of female mortality in most developed countries. This volume provides a unique glimpse into our understanding, at the cutting edge of a variety of disciplines, of this versatile and extraordinary tissue, at the birth of the twenty-first century.

Available in PDF, EPUB and Kindle. Book excerpt: On the basis of a comprehensive literature review and analysis, Nutrition During Lactation points out specific directions for needed research in understanding the relationship between the nutrition of healthy mothers and the outcomes of lactation. Of widest interest are the committee's clear-cut recommendations for mothers and health care providers. The volume presents data on who among U.S. mothers is breastfeeding, a critical evaluation of methods for assessing the nutritional status of lactating women, and an analysis of how to relate the mother's nutrition to the volume and composition of the milk. Available data on the links between a mother's nutrition and the nutrition and growth of her infant and current information on the risk of transmission through breastfeeding of allergic diseases, environmental toxins, and certain viruses (including the HIV virus) are included. Nutrition During Lactation also studies the effects of maternal cigarette smoking, drug use, and alcohol consumption.

Available in PDF, EPUB and Kindle. Book excerpt: The use of drugs in food animal production has resulted in benefits throughout the food industry; however, their use has also raised public health safety concerns. The Use of Drugs in Food Animals provides an overview of why and how drugs are used in the major food-producing animal industriesâ€"poultry, dairy, beef, swine, and aquaculture. The volume discusses the prevalence of human pathogens in foods of animal origin. It also addresses the transfer of resistance in animal microbes to human pathogens and the resulting risk of human disease. The committee offers analysis and insight into these areas: Monitoring of drug residues. The book provides a brief overview of how the FDA and USDA monitor drug residues in foods of animal origin and describes quality assurance programs initiated by the poultry, dairy, beef, and swine industries. Antibiotic resistance. The committee reports what is known about this controversial problem and its potential effect on human health. The volume also looks at how drug use may be minimized with new approaches in genetics, nutrition, and animal management.
