Available in PDF, EPUB and Kindle. Book excerpt: The Federal Office of Farm Management reports (March, 1914) that there are 21,749,651 dairy cows in the United States. Considering the average productive life to be six of seven years, it is evident that 3,000,000 to 3,500,000 heifers must be grown each year to maintain the present number of dairy cows. The Government estimate of the cost of raising each to a productive age is $61.41. It therefore is important, not only that they be economically grown, but that they make such growth as will result in greatest production at maturity. A review of literature shows that little has been done experimentally on the growth of dairy cattle. While the scientific facts of growth have been worked out with man and with laboratory animals, almost no application of these facts has been made to the development of farm animals. The basis of this thesis is a study of growth of dairy heifers from birth to first parturition. The development of animals kept under different planes of nutrition is considered and compared with that made by those fed rations which are thought to be suitable for normal growth. From this data a standard of growth is calculated showing the size a heifer should attain at any particular age.

Available in PDF, EPUB and Kindle. Book excerpt: Bovine Reproduction is a comprehensive, current reference providing information on all aspects of reproduction in the bull and cow. Offering fundamental knowledge on evaluating and restoring fertility in the bovine patient, the book also places information in the context of herd health where appropriate for a truly global view of bovine theriogenology. Printed in full color throughout, the book includes 83 chapters and more than 550 images, making it the most exhaustive reference available on this topic. Each section covers anatomy and physiology, breeding management, and reproductive surgery, as well as obstetrics and pregnancy wastage in the cow. Bovine Reproduction is a welcome resource for bovine practitioners, theriogenologists, and animal scientists, as well as veterinary students and residents with an interest in the cow.

Available in PDF, EPUB and Kindle. Book excerpt: From birth to first calving, the replacement heifer undergoes tremendous changes anatomically as well as in feeding and management practices. The calf changes from being a pseudo-monogastric to a full ruminant within a period of two months. During the same period, the calf is fed colostrum, milk, or milk replacer, and starter with or without hay. Notably, the lifetime milk production and health of a dairy cow is highly dependent on early life nutrition and management of the calf and, subsequently, the heifer. Hence, animal scientists continue to investigate critical areas such as colostrum feeding, the level of liquid feeding, gut microbial succession, energy and protein levels, housing, health management, and their interactions with the animal in an effort to help dairy producers raise successful and sustainable dairy enterprises.
