Why do cows become soft and how to solve this problem?


Each owner of a cow represents and even knows what a chagrin it is if you do not receive offspring and milk from the animal in due time. But, unfortunately, this phenomenon occurs more and more often. Such females are called juveniles. So what is the reason and how to solve this problem, find out with us.

Why is a cow called yalova?

Barrelness is a phenomenon when an animal did not produce offspring in one season, that is, it did not have a fruitful insemination. Yalova is called a cow, which has not had a pregnancy for three months after calving. This period covers the period from the 90th day after calving and from the 30th day at the heifers after the occurrence of such a period up to the moment of pregnancy.

In the practice of animal husbandry, the freshwater is called the cow in the first three months after calving, and then, if it does not become pregnant again, it is classified as barley. That is, in fact it is a kind of infertility of cows, only temporary, as it is treated. On livestock farms, there is a special account of raw material - the number of females that did not produce offspring during the year.

Some subtleties

Infertility of heifers and adult cows is easy to detect as a result of a gynecological examination, as well as by the behavior of the animal. The first signs of this phenomenon is the lack of hunting. As a rule, after calving in the first month, about 20-23% of the cows resume hunting, in the second - more than 50% and in the third month - 18-22%. An unfertilized burenka, after 60 days, is almost considered juvenile. In young heifers, fertility should be about 90%, while in adult females this figure varies from 70 to 75%.

Why do cows remain barren?

The causes of livestock infertility are many. But they need to take everything into account, because cows can for a very long period, and even permanently lose the ability to breed.

One of the very first and most common causes of barley is the wrong feeding ration, or rather, under-feeding. All the reasons related to the defective diet of the animal, are called alimentary. Most often they are observed in the winter period. Excess silage, concentrates and pulp leads to a deterioration of metabolism, to subsequent weight loss and the ability to carry the fruit.

Constant under-nutrition causes the following problems:

  • disorder of the nervous and endocrine systems;
  • arrhythmia of sexual cycles;
  • lack of ovulation;
  • ovarian atrophy;
  • inflammatory gynecological phenomena;
  • afterbirth delay.

Especially poorly affected by improper feeding of cows in the period after pregnancy and in the first postpartum period.

All possible causes

  1. Low protein level (below 60-80 grams) - leads to a decrease in the activity of hormones, as well as disruption of the synthesis of enzymes.
  2. Overeating - impaired function of the endocrine glands leads to the degeneration of the tissues of the uterus and ovaries.
  3. The discrepancy between the content of sugar and protein - normally per 100 grams of protein you need 80-150 grams of sugar.
  4. The lack of trace elements.
  5. Poor conditions - poor light, damp, dirt, low temperature.
  6. Premature insemination or late start.
  7. Incorrect milking.

Immature heifer

One of the most unfavorable causes of bovine cows, which are practically not treatable, is associated with premature insemination of young females. Inadequate nutrition and poor conditions of detention lead to the fact that heifers inhibit the development, they have an underdevelopment of the mammary glands, low weight, poor body condition. Pregnancy is difficult, childbirth often with complications. If it is early to make insemination, then 50% of such individuals after the first calving become juvenile. Under poor conditions of maintenance and underfeeding of young females, they are delayed by 9-12 months.

Abnormalities of the genitals

Another of the causes of barrenness, which is not very common, but still - these are various anomalies of the genital organs. Most often they occur even in the embryonic period of development. For example, as a result of this, cows experience problems such as freemartinism, hermaphroditism, impaired ovarian development, or infantilism.

  1. Freemartinism is a phenomenon characterized by the underdevelopment of the reproductive organs of the cow: the uterus, the vagina itself, the clitoris. Although the ovaries of such females work normally, they are still incapable of producing offspring.
  2. Hermaphroditism - the presence of the animal at the same time the genitals of both the female and the male. That is, in the heifers there is the presence of the testes and ovaries. Such females are culled.
  3. Infantilism - underdevelopment of the genital organs and the absence of sexual cycles. At the same time, there is underdevelopment of both the uterus and the ovaries.

Also, in rare cases, there is a lack of cervix, oviduct and other anomalies in cows.

Immune factor barley

Such a phenomenon as the production of antibodies to semen occurs in many females, including cows. This is a kind of reaction of the body to the penetration of sperm, as on foreign bodies. In this case, sperm antibodies accumulate in the secret of the uterus and vagina and can last up to two months.

Reasons for the occurrence of an immune-barrier reaction can be multiple insemination, injuries of the genital organs, inflammation, improper administration of sperm. Also, the cause of this phenomenon can serve as a lack of vitamin A, which increases the concentration of sperm antibodies. When the immune barrier pregnancy may occur, but the fetus often dies in the early stages of development.

Violations of the rules of insemination and calving

It happens that an animal becomes barren due to improper handling of a person. The first reason is improper insemination. Most often, too much sexual load on the cow, the use of poor-quality material (weak insemination), closely related crossing, violation of sperm injection technology, rough handling of females, violation of sanitary and hygienic norms results in rawness.

Proper calving is a guarantee of further pregnancy. But such phenomena as premature and late fetal extraction, violation of hygiene rules, detention of the afterbirth and others are the cause of further infertility. Since childbirth is a natural physiological process, without the need for experts advise not to interfere with its course. An inept person can only hurt, not help. Cows, if they are healthy, give birth perfectly well without additional help.

Disruption of the natural childbirth process

Most often, a person tries to get the baby out of the mother’s womb as quickly as possible. Therefore, as soon as the fetus is shown, apply various measures. This and the puncture of the bubble, pulling the calf by force. All this often leads not only to trauma to the genitals of the cow, but also to damage to the baby. It is strictly forbidden to remove the fetus during childbirth without the need and control of a veterinarian.

It is also important to observe the female in the postpartum period. At this time, the cow needs additional care and respect. This will help the animal to recover faster and in a month to re-enter the hunt.

Problem solving methods

How to return the ability of the cow to breed? Here, first of all, it is worth considering precisely the reason that caused the problem. If this is due to improper care or feeding regime, then, by taking the necessary measures, you can get rid of barley.

But as for serious gynecological disorders and abnormalities, then without the help of a specialist veterinarian is not enough. And that is not the fact that the problem can be solved. Consider all the same how to return the cow to the former "force"

  1. If the reason is poor care or feeding, then after adjusting the diet and content, the animal can recover in 3-4 months.
  2. If the cause is gynecological diseases, such as inflammation, special treatment is applied. For example, with metritis, a 2% solution of synestrol is injected, tetravit and aminovit is given.
  3. Psychologically and physiological problems are solved only with strict supervision by a veterinarian.
  4. In the stall period, it is necessary to properly select food so that the animal’s body does not suffer from malnutrition or overeating.
  5. It is important to properly organize the day of the cows, it should be enough to walk and be in the fresh air.

How to break yalovaya cow?

Many owners ask, is it possible to get milk from a barren lady? The answer is - you can, but you should try a little.

  • It is not necessary to distribute the animal immediately after the cold period. At this time, there is often a lack of vitamins and depletion of the animal. For a set of milk should give the cow a rest and distribute gradually over 3 months.
  • It is necessary to monitor the groin area so that the udder does not become inflamed.
  • It is important to feed the stew with succulent root and tuber crops during railing.
  • It should be included in the diet meal, cake and molasses with the addition of calcium, phosphorus and salt.

The main thing is to love your animal, care for it, treats it carefully and with respect. Only in this case, it will respond to you in return and will delight you with a large amount of milk.
