  4. Defining Animal Reproduction • Animal reproduction: Process by which offspring are produced by male and female parents. • Involves heterosexual mating, conception, pregnancy, parturition and lactation. • Conception results from fusion of male and female gametes (i.e. spermatozoon and ovum), known as fertilization. • Animals must first attain reproductive age (puberty) before being capable of producing gametes. • Reproduction involves close coordination of various physiological events to be successful. This is usually achieved through the action of reproductive hormones.

  5. Interdisciplinary nature of Animal reproduction • Proper understanding of animal reproduction requires knowledge in diverse fields such as: Reproductive physiology, endocrinology, environmental physiology, cell biology, immunology, genetics, biochemistry, sociology, reproductive diseases, psychology, embryology, obstetrics and so on.

  6. Animal reproduction and economic livestock production • Livestock products such as milk and eggs are directly from reproductive processes. • Meat production depends on production of young animals (reproduction) for growing and fattening. • Profitability of livestock enterprise largely depends on reproductive efficiency.

  7. Role of reproduction in genetic improvement DGy = SD * h2 GI where SD = selection differential h2 = heritability estimate, and GI = generation interval in years.
