Download or read book The Potential Effect Of Two New Biotechnologies On The World Dairy Industry written by Lovell S Jarvis and published by CRC Press. This book was released on 2019-07-11 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biotechnology is expected, by many observers, to have a significant impact on the world dairy industry over the next decade. In this timely volume, Lovell Jarvis analyzes the potential effect of two biotechnologies—multiple ovulation and embryo transfers (MOET) and recombinant bovine somatotropin (rbST—on the dairy industry around the world. According to Jarvis's research, the effects of these two technologies will vary greatly between the developed and developing nations. He predicts that the technologies will be most profitable for the developed nations, where their use will increase milk production and strengthen their positions in dairy export markets. Developing country dairy sectors will probably lose from the use of these two biotechnologies, as their own international trade position will be weakened, though their own consumers should benefit. Jarvis concludes his study with a look at alternative approaches that might improve the competitive position of developing countries in the dairy sector.

Download or read book Ruminant physiology written by Y. Chilliard and published by BRILL. This book was released on 2023-09-04 with total page 864 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the proceedings of the XIth International Symposium on Ruminant Physiology. The papers address ruminant comparative physiology, the rumen ecosystem and metagenomics, nutrient digestion and absorption, methanogenesis, tissue metabolism and gene expression, pregnancy, lactation and growth, adaptation to heat-stress, nitrogen use, nutrition and reproduction, nutrition and welfare and nutrition for sustainable ruminant production. These topics are in line with the current challenges for animal breeding: production efficiency, meat and milk quality, environment (greenhouse gases, nitrogen use), animal welfare and health. The contributions come from research teams in 49 countries of all continents, showing a world-wide interest in ruminant nutrition and physiology. They show the latest techniques and results on ruminant nutrition physiology, including fundamental and integrative approaches, presented in the book on the following sections: (1) Digestion and absorption; (2) Metabolism and hormonal regulations; (3) Nutrition and reproduction; (4) Nutrition and welfare. Proceedings from past ISRP symposia have had a major influence on research and teaching in animal science over the years. Without a doubt, this book, which is of interest to all professionals and researchers who are concerned with ruminant nutrition and physiology, will contribute to this fine tradition.
