Document Summary
A 3% improvement in birth rate results in an additional: 1 million beef calves per year, 3. 2 million pigs per year, 3. 7 million gallons of milk per year. Reproductive tools for genetic improvement: frozen semen, separation of male and female producing sperm, synchronization of estrus, superovulation, embryo transfer, storing of embryos, cloning. Viii: lies directly beneath the rectum separated by the rectogenital pouch, allows manual palpation and/or ultrasound exam of repro tract, each tube in the reproductive tract contains very similar layers, serosa. Give structure to the tube: muscularis. Usually double layer of outer, longitudinal smooth muscle. Blood vessels, nerves, and lymphatics: mucosa. Lumen lined with a single layer of secretory epithelium: structures, ovaries, function. Produce gametes and the hormones estrogen and progesterone. Produces oxytocin, relaxin, inhibin, and activing: anatomy. Called germinal epithelium but no function in producing germ cells (terminology came before functional understanding)
