Prolific Tropical Sheep


Book Description




Prolific Sheep


Book Description

As reproductive performance is an important criterion in animal production, there is considerable interest in prolific breeds. Certain prolific breeds of sheep produce an average of more than two lambs per pregnancy. With the "discovery" of the Finnsheep and Romanov breeds, followed in the 1980s by the discovery of the Booroola gene in Australia, research into prolificacy has escalated. Also, artificial insemination and embryo transfer techniques now make it easier to move prolific breeds across continents and incorporate prolificacy into local populations. There have also been a number of recent studies on the physiology, nutrition and management of prolific sheep. Previously there has been no single book reviewing and collating current knowledge of prolific sheep. This book fills the gap and covers all aspects of the subject, including descriptions of the various breeds. Written by authors from every region of the world, the book is a comprehensive work on this subject.




Genetics of Reproduction in Sheep


Book Description

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.




Sheep And Goat Handbook, Vol. 4


Book Description

The Sheep and Goat Handbook includes presentations made at the International Stockmen's School, January 8-13, 1984.The faculty members of the School who authored this fourth volume of the Handbook, along with books on beef cattle, dairy cattle, and horses, are scholars, stockmen, and agribusiness leaders with national and international reputations.

Relevant information and concepts from many related disciplines are included.




Hair Sheep Of Western Africa And The Americas


Book Description

Perhaps less than 10 percent of the world's sheep have hair coats instead of wool fleeces, but as an animal resource, these sheep are important far out of proportion to their numbers. Hair coats provide an advantage in the face of the heat, humidity, and other stresses of the tropics. Small in body size, early to mature, and often highly prolific,

Pastoralism in the New Millenium


Book Description

Pastoralism refers to the type of farming system which uses extensive grazing on grasslands for livestock production. This type of farming covers 25 per cent of the world's land area and supports 20 million households. It makes substantial contributions to the economies of developing countries, although agricultural encroachment, conflict and drought continue to erode this way of life. This publication considers key policy issues and trends involved in attempts to improve the livelihoods of pastoralist families and communities.




China, Multiple Cropping and Related Crop Production Technology


Book Description

This study tour was organized and led by FAO and the Government of China with the financial assistance and support of the United Nations Development Program (UNDP). It was the tenth in a series of 13 inter-regional study tours to China organized for 1977-1979 by FAO, the Government of China, and the UNDP. These study tours provide an opportunity for developing countries to learn from the Chinese experience in agriculture, forestry and fisheries. The terms of reference of the study team were: (1) to study multiple cropping and related crop production technology in China; (2) to determine the relevance and applicability of Chinese multiple cropping methods and techniques to the participating countries
