This book was released on 2012-12-06 with total page 856 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two questions could not be avoided in the avant-propos of this book; (i) what is the importance to man of ruminant livestock, and (ii) what results of practical relevance in the growing mountain of scientific verbiage could be found in the Proceedings of this Symposium. Herbivores are an integral and critical part of the natural ecosystem which must be preserved because of their impact on human welfare. Wh at makes ruminants especially important to man is that they can thrive on fibrous forage and are thus the only viable enterprise over much of the earth's surface where crop growing is impracti cable. They contribute a wide array of products in addition to 50000 000 tonnes ofmeat (1977) and represent a 'capital reserve' that can be drawn upon in times of emergency: milk for example (450000000 tonnes) can make the difference between subsistence and starvation. About 60% of the world's meat and 80 % of the milk are produced by one third of the world ruminant population in the developed regions and as much as 99 % of the power for agriculture is provided by the ruminant population in developing countries. For the next two decades, a probable increase by 30 % for . cattle and buffalo and more than 40 % for sheep and goats is expected by improving health, fertility, nutrition and genetic potential rather than feed resources.

This book was released on 2018-03-13 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ruminants were domesticated in the Middle East about 10,000 years ago and have since become an inseparable part of human diet, society, and culture. Ruminants can transform inedible plant fiber and non-protein nitrogen into meat, milk, wool and traction, thus allowing human utilization of non-tillable land and industrial by-products. The nutritional flexibility of ruminants is conferred by the rumen´s complex microbial community. Driven by rising income and population growth in emergent economies, the global demand for livestock products, including milk and meat from ruminants, has been increasingly growing, and is predicted to continue growing in the next few decades. The increase in production necessary to satisfy this rising demand is putting much pressure on already dwindling natural resources. There are also concerns about the emissions of methane and nitrous oxide, potent greenhouse gases associated to ruminant production. The need to make ruminant production more efficient in the use of natural resources poses a big challenge to ruminant science, and within it, rumen microbiology. Recent years have seen important advances in basic and applied rumen microbiology and biochemistry. The knowledge generated has significant implications for the efficiency and sustainability of ruminant production and the quality of ruminant products for human health. The present compilation is an update of recent advances in rumen microbiology and ruminant digestion and fermentation, including original research, reviews, and hypothesis and theory articles. We hope that the experimental results, discussion, models and ideas presented herein are useful to foster future research contributing to sustainable ruminant production.

Book Synopsis Evaluation of Feather and Hair Meals as Protein Supplements for Ruminants by : Adeshina O. Aderibigbe
Download or read book Evaluation of Feather and Hair Meals as Protein Supplements for Ruminants written by Adeshina O. Aderibigbe and published by . This book was released on 1981 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objectives of this study were to nutritionally evaluate various feather and hair meals (FM, HM) as protein supplements for ruminants and to study the in vitro/in vivo relationships of diets supplemented with FM and HM. In vitro (rumen and enzymes) studies, five in vivo digestion trials and a feedlot performance trial were conducted to accomplish these objectives. FM or HM supplied 40 to 50% of the total N in the supplemented diets used for the in vivo studies. In vitro rumen studies showed that HM was a better supplementary N source than FM or cottonseed meal (CSM). Protein supplements were better utilized at lower roughage:concentrate ratios, and urea supplementation improved the utilization of FM. Different degrees of processing had no effect on the level of N in FM. Pepsin-HC1 digestibilities of crude protein (CP) and dry matter (DM) in FM increased with increasing hydrolysis period up to a point and then decreased slightly, but varying the degree of processing (57 to 78% pepsin digestibility) did not affect in vivo digestibility of FM by growing lambs. Utilization of FM was low in in vitro (rumen) but high in in vivo trials, indicating some potential for reticulo-rumen bypass. The final weights, average live and carcass gains, feed consumption and feed efficiency were higher for animals fed FM and HM than for those fed CSM. The FM and HM diets also had superior economic (cost) advantage in converting feed to gain as compared to the CSM diet. In vitro enzyme nutrient digestibility generally increased with increasing enzyme: N ratios. In vivo CP digestion and N retention were best predicted by a pepsin-pancreatin combination. In vitro pepsin DM digestibility was the best predictor of in vivo DM and organic matter (OM) digestibilities, but in vitro rumen digestibility of DM gave the highest correlation with in vivo digestible gross energy (GE). In vitro digestibility of nutrients by pancreatin was a very poor predictor of in vivo digestibility of nutrients in ruminant diets of the type used. This study demonstrated that FM and HM (when properly processed) were superior to CSM (on a per unit of N basis) when fed as the only protein supplement in diets for ruminants. The study also showed that in vitro proteolytic enzyme and rumen digestion studies can be used effectively to predict in vivo digestibilities of nutrients in ruminant diets.

Download or read book The Rumen Microbial Ecosystem written by P.N. Hobson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 741 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Preface to the first edition of this book explained the reasons for the publication of a comprehensive text on the rumen and rumen microbes in 1988. The microbes of the ruminant's forestomach and those in related organs in other animals and birds provide the means by which herbivorous animals can digest and obtain nutriment from vegetation. In turn, humans have relied, and still do rely, on herbivores for much of their food, clothing and motive power. Herbivores also form the food of carnivorous animals and birds in the wild. The importance of the rumen microorganisms is thus apparent. But, while a knowledge of rumen organisms is not strictly neces sary for the normal, practical feeding of farm animals, in recent years there has been much more emphasis on increasing the productivity of domesti cated animals and in rearing farm animals on unusual feedstuffs. Here, a knowledge of the reactions of the rumen flora, and the limits to these reactions, can be invaluable. In addition, anaerobic rumen-type microor ganisms are found in the intestines of omnivores, including humans, and can be implicated in diseases of humans and animals. They are also found in soils and natural waters, where they playa part in causing pollution and also in reducing it, while the same organisms confined in artificial systems are essential for the purification of sewage and other polluting and toxic wastes.
