synchronization role in reproduction

In the modern world of animal production, natural – Maximum use of physiological capabilities is one of the most important problems of livestock breeding and the necessary condition for successful reproduction.

 

Reproduction – Repeated production, still production, ability to create multiplication function. Performing this function is therefore a reproductive system. Agricultural animal reproductive system consists of two systems with different morphology, male and male cattle gene systems. Only biologically mature animals have the ability to reproduce.

 

The reproductive system of the organism is under the influence of a hardly organized system comprising five hierarchical components: corticus nuclei, hypothalamus, pituitary, peripheral endocrine glands, and     target “ Organs (vagina, uterus, ovaries, etc.).

 

Hypothalamus – The brain is a bunch of nuclei present in the brain that constitutes an endocrine system controlling body. It presents the gonadotropin gonadotropin – relaying hormones, thus stimulating the effect of pituitary.

 

Pituitary   – Is an endocrine gland located in the brain and produces important biologically active substances, so-called hormones, which after reaching the circulation are targeted to the target organs and exercise physiological functions. Gonadotropin is formed in the pituitary and is excreted: 1) maluteine ​​hormone – In ovaries, the ovulation / release of oxygen is released and promotes the development of the follicle's yellow body and the growth. 2) follicular stimulating hormone – Promotes the development of ovaries, the maturation of the follicle and the preparation of eggs for fertilization. Also, it increases the concentration of hormone estrogen.

 

Ovaries – A pair of organs that have two distinct functions: Hormones production (estrogen, progesterone) and egg production (maturation of follicul, ovulation, and mature egg). Estrogen – They are synthesized into ovary cells, yellow body and placenta in the follicular stimulating hormone. It provides the sex cycle. Progesterone – It promotes normal macular degeneration and plays a major role in the preparation of the embryonic enzyme by the mucous membrane of the uterus.

 

WIDER   – Consists of uterine body and cervix. The uterus has the following functions: Dena (excretion of mucous membranes), wearing the fetus and fetching the fetus during childbirth.

 

After a thorough study of the endocrine system by scientists, the elaborated circuits and hormonal drugs were developed to influence beef reproduction, which was successfully achieved. Hormones regulate reproductive development. Researchers who study the hormones at the cellular level are often referred to as &quin; gates &dquo; This means that hormones help cells to live or perceive a nervous signal.

 

Sexual innovation is a defining period and certain days. Success of artificial fertilization depends on the accuracy of the start of the new start and the proper selection of time for fertilization. In order to determine the optimal time for fertilization of sexually transmitted feces and sexually mature beets, it is necessary to take into account the physiological changes revealed at different stages of sex cycle, which occurs at the power, excitation, estrogen (sexual intercourse) and ovulation. All these stages of sex cycle have its characteristic features. It is important to know that the symptoms of sexually transmitted infections are not so rarely shown, and often the techniques of artificial insemination have been brought to error, resulting in the loss of sexually abused and unsafe livestock.

 

Intensive reproduction is an effective way to improving the functionality of cattle. To achieve this, synchronization of sexual ailments is the best way to treat the animal.

 

The main purpose of synchronization of sexually transmitted is:

 

  • Animal group together with fertilization in one period of time;
  • Childbirth at one time period, according to animal groups;
  • Reduction of intervals among pregnant women;
  • Problems solving in cows that have long been independent of sexually transmitted;
  • Decrease of frustration caused by infertility;
  • Change the seasonality of childbirth.

 

Cows are available for synchronization which have normal conditions of ovaries and uterus. A new synchronization method can only be used by a veterinarian who can evaluate the morpho-functional condition of the cervical uterus and ovaries by using the transparent palpation method. The synchronization process involves selection of animals, assessing their physiological condition,   Preparing the necessary preparations and sperm. The optimal time of artificial seeding is determined by synchronized sexually transmitted time.

 

Company „ Invet “ Provides hormonal preparations for sexually transmitted infections for sexually transmitted teaks and sexually mature teaks (Enzaprost, Ovarellin, Prid Delta), manufactured in France by the company „ CEVA ” successfully used by the world's largest breeding cattle breeder   Farms. These hormonal preparations are used according to a defined scheme.

 

Enzoprost   – (ENZAPROST) - active ingredient DinoProst. Character –

 

ü It stimulates the yellow bodies in the ovaries, followed by esterus (sexually detached) and ovulation (withdrawal of the ripening follicle and leaving the egg);

 

ü  Has a strong stimulating effect on the uterine smooth muscles.

 

Ovarellin   – (OVARELIN) - active   As a substance is the   gonadorellin   – Synthetic analog gonadotropin – reeling hormone. Gonadoreline stimulates the synthesis and secretion of gonadotropin, maluteineizers and follicular hormones of pituitary glands.

 

Character & ndash; The ovarellin is used to regulate reproductive function in cows and sexually matured decks:

ü  Delayed ovulation treatment;

ü  For the treatment of follicular cyst;

ü  During infertility for the treatment of ovarian hippopnosis;

ü  To synchronize esstrous.

 

Prid Delta   (PRID DELTA) – The active ingredient is   progesterone   lubricates the intravaginal application using a combination of dinooprost.   description –

 

ü  Progesterone regulates sexual cycle, prepares the organism for fertilization and malice;

ü  Progesterone prepares for implantation of the uterine embryo and then preserves the stock;

ü  Progesterone strengthens gonadotropin   secretion of reclining hormones. The secretion of hormones (maluteinezed and follicular mixed) stimulates the synthesis of estrogen, while the peak concentration enables escrew and ovulation.

 

New technologies are successfully used in modern practical veterinary medicine, which is an indicator of progress, but correct use of these technologies and correct interpretation of the results.
