Question

How lactation period increased

Answer 1

Breakthroughs in biotechnology. have made it possible to manipulate physiological mechanisms controlling the growth and development of organ systems, as well as processes such as milk secretion that are of economic importance. Recombinant derived bovine growth hormone (bSTH) has a dramatic effect on increasing milk production and mammary growth in dairy cattle. This paper briefly summarizes the biology of lactation, using the dairy cow as a model. It then reviews a number of experiments in which the dramatic influence of bSTH on milk secretion and mammary gland development has been shown and alternative methods for increasing the efficiency of mammary gland function have been examined....
