Cases where the afterbirth of a cow goes out of time or do not come out at all now are rarely found. Official statistics say no more than 5% in prosperous farms and 30% in problem ones. However, this is a very serious postpartum complication and it is better to be prepared for it. Therefore, we will further analyze the reasons for the detention of the placenta in cattle, make a diagnosis and prescribe treatment with traditional and clinical methods. Plus, you will learn what to do in certain unusual situations.
Why is there a delay?
The placenta or, in the language of medicine, the placenta is the amniotic membrane that envelops the calf in the womb. Ideally, she herself should be released within 2-6 hours after delivery. It is allowed to delay the afterbirth up to 10 hours, then you need to sound the alarm, call the specialists and urgently help the cow.
The reasons may be indirect, that is, characteristic of cattle in general and personal. The following are indirect:
- a monotonous diet inevitably causes a deficiency of a certain group of vitamins and minerals;
- depletion of the body of the cows after she rested;
- abundance of high-calorie feed and, as a result, obesity;
- reduction of walking time or the complete absence of prenatal exercise;
- excessively large fruit or the birth of twins.
With personal afterbirth delays, the cow is a little more complicated. It all depends on the cow itself. So, the previously transferred endometritis, mastitis and any cold during pregnancy provide a serious cause for concern. In addition, there are rocks predisposed to the curvature of the birth canal, weak contractions and other deviations from the norm.
What threatens to delay
Here it is important how much time does not go after the last. With a short delay in the separation of the afterbirth in cows up to 10 (maximum 12) hours, there is nothing particularly frightening to the cows. But any delay is always stressful, especially for the first-timer cow. As a result of such a shake-up, colostrum production may be reduced. In this case, the problem is solved with good feed, soothing injections and care.
Worse, if the delay is delayed to days. Overwhelmingly, this situation is solved by medical stimulation or by folk methods. But in any case, such an intervention does not pass without a trace. The cow must be registered, and the history of the disease is started. In the first 3 months after the appearance of the calf, she is at risk. Gynecology and uterine diseases are detected in 70% of such cows.
If the amniotic sac did not come away after a day, then you need to worry seriously. The fact is that the shell is literally stuffed with hormones, and this environment is ideal for the development of pathogens. Simply put, the afterbirth begins to rot, which ultimately can lead to sepsis and, as a result, to the death of the cows.
Traditionally, treatment is started after a cow’s afterbirth does not occur within 10 hours. Until that time, stimulating massage and safe folk methods are used.
Share the complete delay of the amniotic sac and not complete or partial. The first case is when most of the bag remains inside the cow. And with a partial delay, the bag goes almost all, but inside there are small pieces of the afterbirth. Full delay is easy to diagnose, because it is clearly visible. If the afterbirth is not completely separated, then it is very important to notice it in time.
To diagnose the delay in the discharge of the placenta is not difficult. The veterinarian puts on deep sterile gloves, inserts a hand into the vagina of the cow and feels the uterus for residual amniotic sac. The process is simple, but experience is required, the layman cannot be trusted with such things.
After an afterbirth after calving, the cow should be closely monitored. Burenka tends to simply eat their own afterbirth. As a result, the owner thinks that the afterbirth has not gone out and begins treatment, which in this case may be harmful.
Simple ways to stimulate
First of all, remember - you should not even try to separate the latter with force, the amniotic sac should go out on its own, and radical methods are already an extreme case and you cannot do without the help of a doctor here.
If the bag is half out and hangs from the genitals, some experienced breeders recommend tying its outer part to the tail of the cow. The idea is that the cow itself will gently pull the bag with its tail, and it will gradually come out. So, the doctors do not approve of such advice, after the birth the animal is in a state of shock and it is not known how the cow will behave. And the result of forceful action can be irreparable.
The first and safest folk remedy is to give the cow water to her amniotic fluid. Burenka solder 3-5 liters of hormone-rich amniotic fluid, and the last comes out quickly and easily (amniotic fluid from another cow will not work). If they did not manage to collect water, then instead of them they first give 2 liters of water with honey or sugar, and in half an hour 3-4 liters of salted water.
The most common stimulants of delayed postpartum activity are oxytocin or pituitrin. Both are injected subcutaneously, but oxytocin is given at the rate of 30-60 units. per centner of cow mass, and pituitrin in the proportion of 8-10 units. per 100 kg.
In parallel with these preparations, subcutaneous injections of the solution (0.5%) of prozerin are made. All this prick with an interval of 6 hours 3 times a day. Stimulate the uterus can be a solution of sodium chloride (10%) or a solution of magnesium sulfate (25%), 4 liters of any of these solutions is poured into the uterus.
To maintain the overall tone of the cow, she 2 times a day (interval 12 hours), intravenously pour in 200-300 ml of glucose at a concentration of 20%. And together with glucose goes 100-150 ml of calcium chloride (10%).
If the amniotic sac cannot move for a long time (more than 15 hours), it is necessary to begin the prevention of infection and subsequent decay of the afterbirth. To do this, furasolidone sticks are introduced into the uterus. In addition to these, you can also use "Metromax" or "Exuter".
As a radical measure for the separation, hydrochloric acid in solution with pepsin can be used. 300 ml of water is taken, it is diluted with 15 ml of acid and 20 g of pepsin, after which it all flows into the uterus.
If the folk and drug treatment did not give the desired effect, and after a day, the cow does not "give" the afterbirth. So you need to move to action and pull out the bag manually.
Naturally, the procedure is performed in deep sterile gloves and with maximum observance of all sanitary standards. To begin with, epidural anesthesia is done. Usually, a solution of novocaine (1%) is used for this. Next, the veterinarian takes with his left hand and slightly pulls the afterbirth sticking out outside.
Then you need to put your right hand inside and inspect the bag for its connection with the walls of the uterus. If there are no connections, then the last is simply drawn out. After removing the uterus, you need to check again so that there are no torn particles left.
If the bag is not separated from the uterus, then at first its walls are massaged with the fist of the right hand. Usually it helps. In extreme cases, it is necessary to gradually separate the amniotic sac, taking it with two fingers. After surgery, a solution with an antibiotic is poured into the cavity.
Competent prevention is to prevent delays. The retention of the afterbirth in cows in half of the cases is caused by the low activity of animals in the prenatal period. The simplest means here is timely walking. In prosperous farms, the prevention of retention of an afterbirth in cows is carried out by drawing up special schedules for walking pregnant cows.
Also, do not be superfluous to check the diet of pregnant animals. After the termination of the milking, special emphasis should be placed on the variety of nutrition, and not on its caloric content. Obesity just provokes delays. If there is no physical ability to diversify the diet, then a month before the birth you need to pierce the cows a full course of vitamins and buy mineral supplements. It will be cheaper than treatment. And for primiparous cows this is a mandatory procedure.
