Ovaries of the dairy cow. During pregnancy, no follicles develop to maturity and heat does not normally occur. Oxytocin from the pituitary gland releases the milk when the baby suckles. A new sensitive test measures the amount of the hormone, oestrone sulphate, present in a sample of faeces. The infundibulum catches the egg as it is released from the ovary at ovulation and moves it to the enlarged upper end of the oviduct called the ampulla.

Also called gestation period. These maintain the lining of the uterus and prepare the mammary glands for milk secretion. The internal parts are located beneath the rectum, which allows rectal palpations of the tract to be done easily. Other abnormalities such as two cervices, absence of one uterine horn, or blockage of the oviducts also occur. Most other animals restrict reproduction to one or two seasons in the year-seasonal breeders see diagram Dairy producers and Al technicians can prevent insertion of an inseminating rod into these openings, which could result in injury or insemination failure, by knowing their location. Once the baby animal is born it must start to breathe for itself, digest food and excrete its own waste. Numerous undeveloped ovarian follicles are present at birth but they start to mature after sexual maturity. In later stages of development the embryo becomes known as a foetus. Most other nestlings need their parents to keep them warm, clean and fed. The main function of the uterus is to receive the fertilized ovum and nourish it, till it attains full development. The secondary sex organs are a series of tubes that receive semen, transport sperm to the egg so it can be fertilized, nourish the fertilized egg embryo , and allow the calf to be birthed. During this period, the ovaries are relatively inactive except for the functional corpus luteum. Fertilisation involves the fusing of the gametes to form a diploid zygote. The problem of keeping sperm at a low enough temperature is even greater in birds that have a higher body temperature than mammals. Later in the pregnancy the placenta itself takes over the secretion of these hormones. This is called a morula. In many animals including humans the testes descend into the scrotal sacs at birth but in some animals they do not descend until sexual maturity and in others they only descend temporarily during the breeding season. In contrast to the continuous production of sperm spermatogenesis in the male, oogenesis is cyclic. Summary The reproductive tract of a cow is composed of the vulva, vestibule, vagina, cervix, uterus and ovaries. First two cells are formed and then four, eight, sixteen, etc. The relative position of the reproductive tract within the pelvic arch also changes. Structural abnormalities such as freemartinism, double cervix, etc. A mature animal in which one or both testes have not descended is called a cryptorchid and is usually infertile. The urethra conducts both urine and sperms as per requirement.

  1. It produces an alkaline secretion that neutralizes the acidity of the male urethra and female vagina. During pregnancy, no follicles develop to maturity and heat does not normally occur.

  2. Unfortunately the semen of chickens, stallions and boars can only be stored for up to 2 days. It is also sensible to restrict the breeding season because courtship, mating, gestation and the rearing of young can exhaust the energy resources of an animal as well as make them more vulnerable to predators.

  3. It has thick walls and a small opening that is difficult to penetrate because of overlapping or interlocking folds annular rings. Rather, they die, are absorbed by the ovary, and are replaced by newly formed primary follicles.
