Category : Science
Languages : en
Pages : 344
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,

Languages : en
Pages : 156
Book Description
The objectives of this study are: (1) to obtain estimates of genetical and environmental parameters for growth and reproduction characters of three tropical breeds of sheep Morada Nova, Brazilian Somali and Santa Ines; (2) to examine genotype by environmental interactions in order to optimally match these three genotypes with different environments by assessing the effect of different levels of nutrition on productivity of sheep in a semi-arid environment.

Sheep Production in the Tropics
Author: Alan Blake Carles
Publisher: Oxford University Press, USA
ISBN:
Category : Science
Languages : en
Pages : 242
Book Description
This book describes the major components of sheep production and ecology and reviews the "sheep environment," including aspects of climate, vegetation, disease, wildlife, and socioeconomic factors. The major breeds and types relevant to the tropics are described in terms of the main biological characteristics that affect productivity. Also examined are the techniques required in applying the principles of genetics, nutrition, disease prevention, and economics to sheep production systems.

Sheep Production in the Tropics and Sub-tropics
Author: Ruth M. Gatenby
Publisher: Wiley-Blackwell
ISBN: 9780582404045
Category : Moutons - RĂ©gions tropicales
Languages : en
Pages : 351
Book Description
Ex-Libris. Usual Library Markings With No Underlining And Highlighting. Sheep Have Traditionally Formed An Important Part Of The Economy In Much Of The Tropics And Sub-Tropics, But It Is Only In Recent Years That Scientists Have Begun To Recognize Their True Value, Not Only For Their Ability To Convert Low Quality Vegetation Into Tangible Products Such As Meat, Wool, Milk, Skin, And Manure, But Also As A Capital Store In Societies Where Grazing Land Is Communally Owned And Banking Facilities Are Few And Unreliable. With The Increasing Awareness Of The Importance Of The Sheep, Development Projects Aimed At Improving The Standard Of Living Of The Rural Poor Are Now Focusing On Sheep Because, Unlike Larger Ruminants, Sheep Are Owned By The Poorer Sectors Of These Societies. Until Now There Has Been A Marked Gap In The Literature For A Textbook On Tropical Sheep Production For Agriculture And Veterinary Students. This Book Fills That Gap, Providing An Introduction To Breeds Of Sheep In The Tropics, Their Genetics And Environmental Physiology And Covering Such Important Topics As Management, Health, Nutrition, Feeding And Reproduction; Products And Systems Of Production; Products And Systems Of Production; Sociological And Economic Aspects Of Production; And Possible Improvements. The Book Also Contains A Glossary, A Substatial List Of Breed Names And Descriptions, And Over 1,000 References.
