Reproductive System
Overview
A Yankasa ram runs with twenty ewes for a full season, yet only three lambs are born at the end of it. The ram is healthy, willing and mating often, so the shepherd assumes bad luck. The real explanation usually has nothing to do with luck and everything to do with reproductive biology: mating on the wrong day of a ewe's cycle wastes the encounter completely, however many times it happens. Understanding the reproductive system is what turns mating into lambs, kids, calves and piglets.
In this lesson you will meet the parts of the male reproductive system and the parts of the female reproductive system in a farm animal, and learn exactly what each part does. You will follow fertilisation itself, from ovulation through mating to the fused egg implanting in the uterus, and see why the timing of service around oestrus, and an awareness of how long pregnancy lasts in each species, are the two pieces of knowledge that make the difference between an empty pen and a full one.
Objectives
- Identify the parts of the male reproductive system
- Identify the parts of the female reproductive system
- State the functions of the parts of the reproductive system
- Explain the process of fertilisation in farm animals
- Distinguish between the reproductive system of a male and a female farm animal
