Estrous Synchronization Prostaglandin


This hormone is naturally secreted from the non-pregnant uterus of the goat during the estrous cycle. It lyses (destroys) the corpus luteum so the cycle can start over. It is also secreted when it is time for birthing to help with the birthing process. Early studies with few animal numbers have shown that prostaglandin and similar hormones can be used for synchronization in cycling females. Studies have shown that during the breeding season, prostaglandin administered at a dose of …

Because the length of the day determines breeding in goats, light treatment to alter this photoperiod response is a well-known method to help get a doe to come in heat for breeding during the non-breeding season, especially in the dairy goat industry. Artificial lighting is used to mimic a long day (16 hours of either sunlight or artificial light) followed by eight hours of darkness. Then, the does are exposed to 8 …

Understanding estrous cycles, mating, pregnancy and birth is important in managing animals for high reproductive rates. However, in order to understand these things, an adequate understanding of anatomy is crucial. The anatomy sections below describe the sexual and reproductive organs present, outside and inside the goat’s body, as well as their functions in both females and males.

Male Reproductive Tract.

Male Anatomy

The male reproductive tract consists of the scrotum, testis, epididymis, vas deferens, accessory glands and penis. In addition to surrounding and protecting the testes, the scrotum also aids in temperature regulation of the testes due to the presence of numerous sweat glands. The sperm and the male sex hormone, testosterone are made in the testes. Unlike the female, the sperm is produced throughout the reproductive life of the the male. The sperm is …

The specific cause of pneumonia is not easily determined and requires diagnostic help in consultation with a veterinarian. The ultimate cause may be a combination of factors. Management problems such as overcrowding, poor ventilation and inadequate nutrition as sometimes to blame.

Interactive Nutrient Calculator

Practical goat nutrition involves providing sufficient nutrients for a desired level of productivity (milk, meat, or kids) at a reasonable cost. Nutrients are supplied via a combination of pastures, supplements, and other feedstuffs; adequate amounts are required for animals to produce at an economically viable level. For commercial meat goat production, the economics of nutrition are of paramount importance due to their great impact on cost of production and subsequent profit. For show, …
