Control of Pig Reproduction

Control of Pig Reproduction PDF Author: D.J.A. Cole

ISBN: 1483278328
Category : Science
Languages : en
Pages : 675

Book Description
Control of Pig Reproduction focuses on carefully evaluated techniques and technologies involved in the control of pig reproduction. The selection first ponders on the sexual development of male pigs, including early fetal, perinatal, and pubertal periods. The text also discusses testicular steroids and boar taint; interrelationships between spermatozoa, female reproductive tract, and egg investments; and artificial insemination. Discussions focus on androgens, estrogens, deposition of semen and uterine transit, sperm regulation and release by the isthmus, and types of artificial insemination. The manuscript examines endocrine control of sexual maturation in female pigs and sexual differentiation of the stimulatory estrogen feedback mechanism and factors affecting the natural attainment of puberty in gilts. Discussions focus on development of ovarian function and gonadal steroid levels; development of the stimulatory estrogen feedback mechanism; and maturation of negative feedback of gonadal steroids. The text also takes a look at controlled induction of puberty, endocrine control of the estrus cycle, and control of ovulation. The selection is a valuable reference for farmers and readers interested in pig reproduction.
