This book was released on 1968 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Four experiments were conducted (1961-1964) for the primary purpose of studying the milk and milk constituent yields of dairy cows under dry lot and pasture systems of management. The secondary purpose was to compare the health and breeding performance of cows under these two systems. Ninety-eight cows of the Holstein and Jersey breeds were used. These cows were paired on the basis of breed, age, current milk production, previous lactation yields, days in milk, days in gestation and udder health and were assigned randomly to the two experimental groups. Cows in the dry lot groups were fed grass silage and alfalfa hay (periods I-III) or haylage (period IV) whereas, cows in the pasture group were strip-grazing irrigated grass-legume pastures. Both groups were also fed the same concentrate mixture twice daily. Differences in performance between the two systems were not significant statistically (P

Available in PDF, EPUB and Kindle. Book excerpt: Limited research is available that evaluates animal productivity from increasing levels of pasture supplementation to dairy confinement- ype diets. Two 8- eek field studies (fall of 2004, F2004; and spring of 2005, F2005) and an in vitro continuous culture study were conducted to examine animal performance under different combinations of total mixed ration (TMR) feeding and high- uality pasture grazing. Such feeding systems are increasingly referred to as a partial mixed ration (PMR). Cows were assigned to either an all-TMR diet (100T, no access to pasture) or one of the following three PMR diets: 1) 85% TMR-restricted (85T) 2) 70% TMR-restricted (70T) and 3) 55% TMR- estricted (55T). Actual diets during the fall trial became 59% TMR and 41% pasture, 68% TMR and 32% pasture, and 79% TMR and 21% pasture instead of the formulated 55T, 70T, and 85T, respectively. The corresponding actual diets during the spring trial became 65% TMR and 35% pasture, 79% TMR and 21% pasture, and 89% TMR and 11%, respectively. Cows on the PMR diets had access to pasture (annual ryegrass) and grazed as a single group for 7 hD between a.m. and p.m. milkings. In F2004, the TMR feeding system maximized total dry matter intake (DMI) and milk production, but 4% fat- orrected milk (FCM), milk fat yield and protein yield did not differ among diets. In S2005, FCM was greatest for treatments 85T and 100T, and lowest for treatment 70T, with 55T yielding an intermediate value. Milk fat and protein yields were greatest for treatments 85T and 100T compared with those diets that included the greatest amount of pasture. Greatest DM intake from pasture was associated with the greatest concentration of conjugated linoleic acids (CLA, a group of fatty acids with potent cancer- ighting properties) in milk. Also, concentrations of saturated fatty acids in milk fat were greatest for cows consuming TMR. Gross feed efficiencies (kg FCM per kg DMI) were similar for all d.

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
