Mostly goats are reared in extensive small holder systems in developing countries. Goat breeding programmes in these environments have been limited, amongst other factors, by the non availability of pedigree and performance records for traits of economic importance. Cross-breeding and selection play an important role in increasing production in the goats.The development of breeding strategy for the improvement of goats should be based on genetic parameter estimates of economically important traits. Biological, cultural, statistical, socio-economical and management aspects should also be an important component of the selection process.

Goats were domesticated for the triple purpose of milk, meat and hair. Although the development of milk and hair producing animals did not go together, the development of meat and hair together worked very well and there are several breeds like Angora which in addition to providing fiber, are excellent meat animals too. The development of meat breeds was favored by natural selection. The characters which aided to this aspect were high fertility rates and the relatively more active life which goats were forced to lead in order to get enough of nutrition in poor agricultural lands, deserts etc. where these animals were domesticated. These animals were exposed to the vagaries of the environment resulting in decline in production traits such as milk, meat etc. But meat production was not. Most of the breeds of Asia and Africa are thus predominant meat breeds which have been improved little by conscious effort of breeders. Some of them still have slow growth rate and feed conversion efficiency. The preference for goat meat had eroded the dairy potential of Indian goats, as the fastest growing males are slaughtered for meat purposes and only poor animals are retained for breeding purposes. Careful selection and utilisation of breeding males can alleviate this problem to a large measure and animals for both milk and meat production can be developed.There are several goat breeds that have good potential for meat production. Generally, there have been limited planned selection and breeding programs carried out by animal scientists to improve rate of growth and carcass composition of goats. As a result, many goat breeds deposit less intramuscular and subcutaneous fat. In the past, domesticated meat animals were selected for heavier mature weight and greater rate of gain. Selection for such parameters usually resulted in undesirable characteristics because some of the animals had not only gained weight faster and were heavier at maturity, but also had more subcutaneous and intramascular fat. Since consumers currently prefer leaner red meat, the livestock industry is making significant changes to satisfy these demands. Goat meat has unique attributes which will be beneficial to the present day consumer. Goat meat has 10% more lean carcass than cattle. At the same time the fat content is lower by 47% than beef. These qualities of the goat meat need to be emphasized so that the general public can become aware of this useful product.

Worldwide, almost 90% of the human food supply is provided by only 15 crop species and eight livestock species. The eight livestock species useful to man include cattle, buffalo, sheep, goat, pig, poultry, camel and horses. All or some of these species provide milk, meat, skin, fiber and manure for use of mankind. Whereas, milk and meat are important component of human food supply, skin, fiber and manure are also useful in different manner. Goats are important food-producing animals especially in tropical and subtropical regions. Goats are the most adaptable and geographically wide spread livestock species.

A breed of livestock is a group of animals that, through selection and breeding, have distinguishable characteristics and resemble one another and pass those traits uniformly to their offspring. Or A breed is defined as a group of animals that has been selected by humans to possess a set of inherited characteristics that distinguishes it from other animals within the same species. A cluster of domestic animals of a species where individuals are homogeneous in certain distinguishable characters which differ from one to the other group of animals constitute the breeds. Breeds are primarily distinguished by visual characteristics: color pattern, polled or horned condition, or extreme differences in form and shape. Breed is indicative of the perception of the breeders and the livestock industry which decides when a group of individuals constitutes a “breed”. Livestock breeds have evolved over time through genetic changes that are both natural and selected by man.

Primarily breeds have been developed to provide increased production of meat, milk and/or wool, pashmina within a certain environmental area. This breed development is a process of continuous selection over a number of generations so as to stabilize the characters in the animals for the selected traits. The distinguishable characters are quite often color markings, size, and shape, hair pattern which may have little economic significance in terms of meat, wool or pashmina production. Breed development may have begun soon after animals were first domesticated. Breed is a group of animals related by descent and similar in most characteristics like general appearance, features, size, configuration, etc. In most cases, selection has been practiced for many generations in order to fix certain characteristics in the breed. The goat breeds have since long been described primarily in terms of physical conformation (chiefly, ear, nose, face and horn), body coat/colour characteristics and body measurements with subtle reference to production traits. Today there are more than 300 breeds of goats, and they live in climates ranging from high altitude mountains to deserts. Some breeds are known by the same name in different places, but are phenotypically different from one place to another. Conversely, there are breeds that look alike but have different names in different places.

Over the past 12,000 years Homo sapiens have moved from the hunter–gatherer life-style to settled agriculture to advanced civilization in urban society with improved quality of life. Livestock has played an important role as an instrument of bringing out this change. Farmers all over the world, attach great importance to livestock ownership as a source of nutrition, as a mechanism for capital accumulation, and concomitantly, as a symbol of wealth and status in the community. Just as in today’s society, money is used to exchange goods and services, livestock including goats used to play the same role in times gone by. Most farmers consider livestock as a important resource for income generation. Livestock sector plays a significant role in supplementing family income and generating gainful employment in the rural sector, particularly among the landless, marginal and small farmers and women, besides providing cheap nutritional food to millions of people. History indicates that livestock has been not only a resource, but also an instrument of dominance and a source of conflict in the society. Livestock especially small ruminants have often served as a means for exchange of goods and services and thus becoming increasingly important in the growth of agriculture in developing economies.

Livestock species which man domesticated for improving the quality of human life include goat, sheep, cattle, buffalo, pig, poultry, horses and camels. Among these goats were the first among livestock species domesticated by man. Goats are among the smallest domesticated ruminants and have served mankind longer than cattle or sheep. Goat is an important source of meat, milk, skin, fiber and manure since then. Traditionally goats have been an important source of income generation among small households. Goats have been used to buy salt, cloth and groceries in many communities. Goats provide a large part of the cash income for smallholder farmers. Goats are friendly animals; with proper attention they maintain good health and can be managed easily even by children.

Sailors and other explorers out on the high seas kept goats as a ready stock of meat & milk on long voyages. Captain Cook’s goat had already sailed around the world before it entered on its first voyage with Cook, and helped save everyone on board the ship from scurvy. Goats are some times kept as pet or companion animal. Their use as pet is common in European countries especially U.K. Some owners keep goats for purpose of goat shows.

CONTRACEPTION DUE TO MISALLIANCE AND TERMINATION OF PREGNANCY IN BITCHES

It is obvious that breeders maintain varieties of breeds but mismating do occur within their own premises and sometimes by unwarranted stray animal.

Misalliance complicates too many other problems.

Incidence of mismating is 15 to 20 percent in canine breeding.
