What is the reproduction cycle of a cow?
cycle in the cow averages 21 days (range is 17–24). During this time, the reproductive tract is prepared for estrus or heat (the period of sexual receptivity) and ovulation (egg release). Figures 2 and 3 outline the sequence of anatomical and hor-monal changes that occur during a typical 21-day cycle in which pregnancy does not occur.
What are the components of the female reproductive system?
The major organs of the female reproductive system include:
- Vagina: This muscular tube receives the penis during intercourse and through it a baby leaves the uterus during childbirth.
- Uterus: This organ holds and nourishes a developing fetus, if an egg was properly fertilized.
- Ovaries: The female gonads, the ovaries produce ova. ...
- Fallopian tubes: These small tubes transport ova from the ovaries to the uterus. ...

What is the reproduction of cow?
After every 21 days the ovary releases a mature ovum and the cow comes on heat. The ovum travels through the fallopian tubes to the uterus. The release and movement of the ovum down to the uterus is called ovulation. If mating is done at this time, fertilization will take place.
What is the function of cow reproductive system?
The reproductive organs of the cow with the exception of the vulva are located within the abdominal cavity. These organs are a series of tubes that receive semen, transport sperm to the ovum so it can be fertilized, nourish the fertilized ovum (embryo), and allow the calf to be birthed.
Do cows have reproductive organs?
The cow's two ovaries are oval to bean-shaped organs that are 1—1.5 inches long and located in the abdominal cavity. 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.
What are the different parts of reproductive system of a cow state their functions?
The reproductive system of the cow is designed to transport spermatozoa toward the ovary and to transport an ovum toward the spermatozoa. The parts of this tubular system include the vestibule, vagina, cervix, uterine horns, and uterine tubes.
What is reproductive system of animal?
It focuses on the gonads (sex organs), associated ducts and glands, and adaptations that aid in the union of gametes—i.e., reproductive cells, male or female, that are capable of producing a new individual by union with a gamete of the opposite sex.

Does a cow have a uterus?
Uterus The uterus in cattle is composed of three distinct regions: the uterine body and two uterine horns. Following the cervix, the uterine body remains a single tube. The uterine body is approximately 1 inch in length and functions as a “common area” of the two uterine horns that follow.
What are the reproductive system of male cattle?
The reproductive tract of the bull consists of the testicles, secondary sex organs, and three accessory sex glands. These organs work in concert for formation, maturation and transport of spermatozoa, which are eventually deposited in the female reproductive tract.
What are the 3 main functions of the female reproductive system?
Everything to Know About Female Reproductive Organs It has several important functions, including: releasing eggs, which can potentially be fertilized by sperm. producing female sex hormones, such as progesterone and estrogen. providing an environment for a fertilized egg to develop during pregnancy.
What is the function of the oviduct in a cow?
The bovine oviduct provides the environment for sperm transport and capacitation, oocyte transport and maturation, fertilization and early embryonic cleavage. Gamete interactions in the tube occur in contact with both the tubal epithelium and the oviduct fluid secreted by these cells.
What is the function of the cervix?
What is the purpose of your cervix? Your cervix is a passage that allows fluids to flow inside and out of your uterus. It's also a powerful gatekeeper that can open and close in ways that make pregnancy and childbirth possible.
What is the function of ovary in animals?
ovary, in zoology, female reproductive organ in which sex cells (eggs, or ova) are produced. The usually paired ovaries of female vertebrates produce both the sex cells and the hormones necessary for reproduction.
What is the importance of knowing about the reproduction cycle in livestock?
A good understanding of the normal estrous cycle in cattle can help producers address reproductive challenges in both heifers (young female dairy or beef animals that have not yet had their first calf) and cows (female dairy or beef animals that have had at least one calf).

How many ovaries are there in cows?
There are two ovaries in cow and they are right ovary and left ovary. Right ovary is caudal to corresponding kidney. And the left ovary located little and further caudal than right ovary
What are the reproductive tracts of cows?
The reproductive tract of a cow is composed of the vulva, vestibule, vagina, cervix, uterus and ovaries. 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 ovaries also release ova which carry the maternal genes. Structural abnormalities such as freemartinism, double cervix, etc. can impede reproduction. A lack of understanding of the anatomy of the reproductive tract can lead to poorer conception rates and lower reproductive efficiency.
What is the cervix of a cow?
Cervix, body of uterus and beginning of uterine horns of the reproductive tract of the dairy cow. The cervix and a small portion of the uterus has been cut open. Note the thick folds of the cervix. The body of the uterus is less than 2 inches long before it divides (at arrow) into the uterine horns.
What is the role of the cervix in pregnancy?
Whether by deposition following Al or by migration from the vagina after natural service, the cervix acts as a reservoir for semen. The cervix provides a favorable environment for sperm survival.
How many ridges are there in the cervix?
Three or four ridges or rings within the body or the cervix, called annular folds, can be distinguished by rectal palpation (Fig. 2). The folds must be manipulated rectally while an inseminating rod is passed through to the uterus. The cervix has important functions.
How big is a cow's ovaries?
The ovaries are the primary reproductive organ of the female. In a dairy cow, each ovary is approximately 1.5 inches long and 3/4 inch in diameter (Fig. 4). The ovaries are suspended from the broad ligament near the end of the oviduct and lie near the tips of the curved uterine horns.
How big is the cervix?
The cervix (Fig. 2) is a unique structure within the reproductive tract. It is 4 to 5 inches long and 1 to 2 inches in diameter and lies between the vagina and uterus. This structure is designed to restrict access to the uterus. The area around the opening of the cervix actually protrudes back into the vagina.
What is the vulva?
Vulva. The vulva (Fig. 1) is the external part of the reproductive tract. The thickened folds of skin of the structure are sensitive to changes in estrogen, the hormone (Fact Sheet IRM-2) responsible for estrus (heat).
What are the reproductive organs of cows?
The female reproductive organs consist of the ovary, uterus, cervix, vagina, and vulva. A sketch of the reproductive tract of the cow is shown in Figure 1. Female reproductive tracts of various livestock species are similar to the tract of the cow but differ primarily in the shape of the uterus and cervix.
How long is a cow's reproductive cycle?
In the cow, this cycle averages 21 days in length, although this can range from 17 to 24 days. In this cycle, the reproductive system is prepared for potential establishment and maintenance of pregnancy. Alternatively, in the event that fertilization does not occur or that establishment or maintenance of pregnancy fails, the female returns to estrus. Figures 2 and 3 show the ovarian changes and sequence of events in a typical 21-day cycle in which pregnancy does not occur.
What is the ovulation tube?
The oviduct, also known as the Fallopian tube, begins as a funnel-shaped tube that engulfs the ovary. This funnel portion of the oviduct is called the infundibulum. When ovulation occurs, the oocyte is picked up by the infundibulum and channeled into the oviduct. Fertilization takes place in the oviduct if viable sperm are present, but the oocyte remains capable of fertilization for only a short time. Therefore, it is essential that sperm be present in the oviduct near the time of ovulation. The oocyte moves through the oviduct into the uterine horn within the next 3 to 4 days. If the ovum is fertilized, it begins embryological development; if not, it simply degenerates.
How long does it take for a cow's oocyte to develop?
The oocyte moves through the oviduct into the uterine horn within the next 3 to 4 days. If the ovum is fertilized, it begins embryological development; if not, it simply degenerates. The body of the uterus of the cow is short, while the uterine horns are relatively long and well developed.
What glands control reproductive function?
Reproduction in the female is controlled by numerous hormones secreted from specialized glands called endocrine glands. These secretions are produced in the glandular cells and pass into the blood and lymph systems for transport to specific parts of the body where they produce their function.
Why is it important to understand anatomy and physiology of both male and female?
A good understanding of anatomy and physiology of both the male and female is helpful in successfully managing reproduction. Causes for failures in reproduction must be identified and overcome. Research has led to the development of numerous techniques for managing the reproductive processes of animals.
Where does the fertilized embryo move?
The fertilized embryo moves from the oviduct into the uterine horn, where fetal and maternal membrane development begins. This newly developing fetus grows within a layer of membranes called the placenta, through which nourishment from the dam diffuses. This point of interface is called the placentome.

Pregnancy and The Reproductive Tract
- Major changes in the ovaries, uterus and cervix occur during pregnancy. The presence of the CL on the ovary during pregnancy prohibits development of mature follicles. The uterus enlarges as do the sites of embryo attachment, the caruncles. In the non-pregnant cow these structures are approximately 1/2 inch in diameter, but are 2-3 inches in diameter at calving. A thick mucus plu…
