Techniques adopted in cattle breeding

A. Out breeding :

Out breeding is mating of less closely related or unrelated

animals.The individuals involved do not have a common ancestor in the

preceeding 4-6 generations. (Techniques adopted in cattle breeding)

Cross breeding is mating of animals of different breeds.

It is valuable as a means of introducing desirable characters into new breed

in which they have not existed formerly. The cross breeds exhibit increased

growth and vigour by the blend of desirable dominant genes from two breeds

in the first generation. (Techniques adopted in cattle breeding)

Artificial insemination is the deposition of male

reproductive cells (spermatozoa) in the female reproductive tract by

mechanical means rather than by natural mating. The semen is collected from

the male by artificial means. The semen is inseminated into the female by

placing a portion of it either in a collected or in a diluted form into the cervix

of the uterus by mechanical methods at the proper time and under most

hygienic condition. (Techniques adopted in cattle breeding)

It helps to eliminate the need for maintenance of herd sire, permits long

distance transport of semen by air, avoids spreading of genital diseases,

and increase the rate of conception. Further this method helps better

recording, permits use of semen from injured and old bulls and provides a

chance of detecting any genital abnormalities or pathological infection and

inflammation in cows. (Techniques adopted in cattle breeding)
