Book excerpt: Excerpt from Fertility in Sheep as Affected by Nutrition During the Breeding Season and Pregnancy Twinning. - The percentage lamb crop depends to a considerable ex tent upon the frequency of twinning. Twinning, in turn, largely depends upon the number of ova liberated from the ovary. When Hammond (13) killed and examined 80 pregnant ewes, he found 116 corpora lutea in the ovaries, 101 normal fetuses and 8 atrophied ones in the uteri; this left only 7 eggs to be accounted for. In adult pigs he found fertility to be dependent upon the percentage of fetuses developing normally, whereas in sheep, fertility depended largely upon the number of eggs shed at the heat period. As Kelley (19) has shown, the largest percentage of twins in Merino ewes is produced between four and ten years of age. The fertility of. Young sows is less than that of mature sows because fewer ova are shed (hammond, 12) and no doubt there is a similar relation between age and twinning ln ewes. J ones and Rouse (18) con cluded, from the literature covering a variety of Species, that in animals generally the litter size increases along with the age of the female. This increase usually goes to a maximum, followed by a decline. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book excerpt: Artificial insemination is used instead of natural mating for reproduction purposes and its chief priority is that the desirable characteristics of a bull or other male livestock animal can be passed on more quickly and to more progeny than if that animal is mated with females in a natural fashion. This book contains under one cover 16 chapters of concise, up-to-date information on artificial insemination in buffalos, ewes, pigs, swine, sheep, goats, pigs and dogs. Cryopreservation effect on sperm quality and fertility, new method and diagnostic test in semen analysis, management factors affecting fertility after cervical insemination, factors of non-infectious nature affecting the fertility, fatty acids effects on reproductive performance of ruminants, particularities of bovine artificial insemination, sperm preparation techniques and reproductive endocrinology diseases are described. This book will explain the advantages and disadvantages of using AI, the various methodologies used in different species, and how AI can be used to improve reproductive efficiency in farm animals.

Available in PDF, EPUB and Kindle. Book excerpt: Genetics of Reproduction in Sheep is a compilation of papers that are concerned with the study and application of genetics to the reproduction in sheep. The book is divided into six parts, grouping the papers according to topic. The main topics include genetic variation and selection; the inheritance and the effects of the Booroola gene; genetic strategies for single genes; physiology of genetic variation; the physiological criteria of genetic merit; and the national requirement and systems of husbandry. The text is recommended for those involved with raising sheep and plan to apply genetics in their reproduction, as well as for geneticists who wish to conduct studies on how their field is applied to sheep reproduction.

Available in PDF, EPUB and Kindle. Book excerpt: "An up-to-date review of the pasture and supplementary feed resources available to the New Zealand pastoral livestock industry, and the energy and protein requirements of these livestock. The interactions between animals and their feed resources ultimately determine both the quantity and quality of the feed consumed and thus the level of animal production. An understanding of this area is key to the successful allocation of feed resources. Although the principles discussed in the early chapters are common to all grazing animals, certain aspects of their application are species or system specific, and chapters address these issues. The environmental impact of grazing pastures and supplementing grazing animals is also addressed."--NZSAP Web site

Book excerpt: Animal Agriculture: Sustainability, Challenges and Innovations discusses the land-based production of high-quality protein by livestock and poultry and how it plays an important role in improving human nutrition, growth and health. With exponential growth of the global population and marked rises in meat consumption per capita, demands for animal-source protein are expected to increase 72% between 2013 and 2050. This raises concerns about the sustainability and environmental impacts of animal agriculture. An attractive solution to meeting increasing needs for animal products and mitigating undesirable effects of agricultural practices is to enhance the efficiency of animal growth, reproduction, and lactation. Currently, there is no resource that offers specific knowledge of both animal science and technology, including biotechnology for the sustainability of animal agriculture for the expanding global demand of food in the face of diminishing resources. This book fills that gap, giving readers all the necessary information on important issues facing modern animal agriculture, namely its sustainability, challenges and innovative solutions. - Integrates new knowledge in animal breeding, biotechnology, nutrition, reproduction and management - Addresses the urgent issue of sustainability in modern animal agriculture - Provides practical solutions on how to solve the current and future problems that face animal agriculture worldwide
