What is Animal Biotechnology? Animals are playing a growing role in the advancement of biotechnology. as well as increasingly benefiting from biotechnology. Combininganimals and biotechnology results in advances in four primary areas 1. Advances in human health 2. Improved animal health and welfare 3. Enhancements to animal products 4. Environmental and conservation benefits
Introduction - Biotechnology provides new tools for improving human health and animal health and welfare and increasing livestock productivity. Biotechnology improves the food we eat - meat, milk and eggs Animal biotechnology includes all animals: livestock, poultry, fish, insects, companion animals and laboratory animals
Breed A breed is a specific group of domestic animals having homogeneous appearance, homogeneous behavior, and other characteristics that distinguish it from other animals of the same species and that were arrived at through selective breeding Despite the centrality of the idea of "breeds" to animal husbandry, no scientifically accepted definition of the term exists.
A breed is therefore not an objective or biologically verifiable classification but is instead a term of art amongst groups of breeders who share a consensus around what qualities make some members of a given species members of a nameable subset. The term is distinguished from landrace, which refers to a naturally occurring regional variety of domestic (and sometimes feral) animal through uncontrolled breeding.
Breed - Selective breeding (also called artificial selection) is the process by which humans breed other animals for particular traits Typically, strains that are selectively bred are domesticated, and the breeding is normally done by a professional breeder.
Cattle Breeding - factors affecting breeding efficiency Cattle rearing is an important subsidiary to agriculture in India It has been playing a significant role in India's rural economy. Despite its vast cattle population-cattle productivity is at the rock- bottom Reason-lack of good breeding stock as well as technologies. Reproduction is an important consideration in the economics of cattle production
In the absence of regular breeding and calving at the appropriate time cattle rearing will not be profitable. A healthy calf each year is the usual goal. This is possible only by increasing the reproductive efficiency of the animals Successful reproduction encompasses the ability to mate. The capacity to conceive and to nourish the embryo and deliver the viable young ones at the end of a normal gestation period. Interruption in this chain of events leads to failure-leads the cow to conceive or the embryo to die or to have a premature delivery of the foetus
