Cattle Reproductive System

Cattle are ruminants meaning their digestive system is highly specialized to allow the use of poorly digestible plants as food. The male reproductive organs in the domestic fowl consist of two testes each with a deferent duct that leads from the testes to the cloaca.

The reticulum the smallest compartment is known as the honeycomb.

Cattle reproductive system. During this time the reproductive tract is prepared for estrus or heat the period of sexual receptivity and ovulation egg release. These are introduced into female reproductive system where they fuse with the sperm to form zygote. In the cow this cycle averages 21 days in length range is 17 to 24 days and is concerned with preparing the reproductive system for estrus or heat the period of sexual receptivity and ovulation the release of the egg.

The reproductive cycle during the early stages of the embryo s life the genital system of both sexes develops in exactly the same way. The ovaries under control of the hormones fsh and lh from the pituitary mediate events of the reproductive cycle and reproductive tract through secretion of ovarian hormones estrogens progesterone and relaxin. The reproductive cycle of the cow consists of a series of events that occur in a definite order over a period of days.

The estrous cycle in the cow averages 21 days range is 17 24. First let s look at the parts that make up the reproductive system in cattle figure 1. Anatomy and physiology of the female reproductive system.

Most ai in cattle today is performed with frozen semen. Cattle have one stomach with four compartments the rumen reticulum omasum and abomasum with the rumen being the largest compartment. The reproductive tract of a cow is composed of the vulva vestibule vagina cervix uterus and ovaries.

The structures of the male reproductive system include the testes the epididymides the penis and the ducts and glands that produce and carry semen. There are two ovaries two oviducts two uterine horns a uterine body cervix vagina and vulva. The rectum is located above the reproductive system.

Sexual differentiation occurs in cattle at an earlier stage than in almost any other mammal starting when the foetus is about 40 days old. The cow s reproductive cycle consists of a series of events that occur in a definite order over a period of days. Fowls do not have a penis such as is found in other animals.

Frozen semen may be maintained for years. The testes are bean shaped bodies located against the backbone at the front of the kidney. Extenders permit more insemination doses to be processed from one collection of semen maintain the fertility of the semen longer protect the spermatozoa from sudden temperature or ph change and prolong viability.

Male reproductive system bull the male reproductive organs produce the male gametes the spermatozoans.
