Animal genetics and breeding book pdf
Selective breeding - WikipediaInformal animal breeding started thousands of years ago when hunter-gatherers started domesticating animals. Out of thousands of species available only few were domesticated as the requirements for domestication were numerous: plant diet, fast growth rate, ability to breed in captivity, good disposition, little tendency to panic, and ability to function well in groups [ 1 ]. The domestication greatly increased the nutritional output per unit of land although it also brought new problems, e. These problems were smaller than the benefits of the domestication as hunter-gatherers mostly disappeared. Some of the benefits could be due to a positive effect of animal products on IQ [ 2 ]. The natural selection maximizes survival under the natural conditions.
How to Use Genetic Bio Technologies to Improve Cattle Herd Production - TvAgro, Juan Gonzalo Angel
Reviewed: August 18th Published: October 21st The modern animal biotechnologies, such as animal cloning, transgenesis, sex determination, stem cells, designing new livestock, must be performed on animal gametes including sperm and oocytes, and embryos based on embryology theory. Currently, some key biotechnologies in embryology have become the most powerful tool for animal scientists and breeders to improve genetic construction of animal herds.

Selective breeding also called artificial selection is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits characteristics by choosing which typically animal or plant males and females will sexually reproduce and have offspring together. Domesticated animals are known as breeds , normally bred by a professional breeder , while domesticated plants are known as varieties , cultigens , cultivars , or breeds. Flowers, vegetables and fruit-trees may be bred by amateurs and commercial or non-commercial professionals: major crops are usually the provenance of the professionals. In animal breeding , techniques such as inbreeding , linebreeding , and outcrossing are utilized. In plant breeding , similar methods are used. Charles Darwin discussed how selective breeding had been successful in producing change over time in his book, On the Origin of Species. Its first chapter discusses selective breeding and domestication of such animals as pigeons , cats , cattle , and dogs.
In this first chapter the history of animal breeding is presented. The importance of selection by nature and important aspects of the domestication process will be described. Mankind started to create breeds accompanied with artificial selection years ago. Nowadays, breeding of high productive farm animals, like cattle, pigs and poultry is in the hands of multinational companies which invest a lot of money in state of the art breeding programs. The breeding of sheep, goats, horses and companion animals, e. Animal breeding is aiming at the improvement of animals by changing their genetic abilities for important traits.
