Hello! Tell me what to do! The cow calved 2 months ago. I do it 3 times a day. Gave milk 7.5-6 liters, respectively. Now she’s down to 4.5 in the morning and afternoon, and in the evening 3 liters. Crushed with beets eats, but the hay is bad. Began to lose weight. What could be the reason? Thank you in advance. (Helena)
Elena, good afternoon. Your question is quite relevant, since this problem worries many owners of cows. Such a phenomenon as the reduction of milk yield after calving is quite common. But it is important to remember that each animal is individual and the reason for this may be different. Consider the most common, which are suitable for your description.
Age of animal
You did not specify in your question what your cow has calved and how old she is. Nevertheless, this moment is very important, since each cow will tend to slow down milk yield with age. The largest peak of lactation occurs in the first months by about 6-7 calving. After that, the cows, as a rule, gradually reduce their productivity. This is considered normal and should not cause concern.
Total cow productivity
The amount of milk given during lactation depends on the breed and type of cow. In the first months after calving, as a rule, all cows give up to 50% of the total amount of product for the entire period. That is, dramatically increase the yield, after which there is a natural decline. Only in highly productive dairy animals, high milk yield persists up to 5-6 months after calving. In your case, perhaps, this is also due to the low productivity of the cows.
Incorrect running and feeding during dry conditions.
The amount of milk given after calving depends very much on the correctness of the product of launching and feeding after it. The fact is that in the first months of lactation, the cow's body uses more of its body reserves. Then the forces are restored and the productivity depends on the feeding and conditions of detention.
What does it mean? If during the dry period and during the launch the animal did not receive the required amount of nutrients, then, accordingly, the stock will be low. Consequently, after calving, the cow abruptly uses the entire accumulated stock and all the forces will go to restore the body, and not to produce milk. All the resulting feed will go to restocking, and the yield will decrease.
Judging by your description of the fact that the cow is losing weight, I am more inclined to this reason for reducing milk yield. The problem can be corrected by the next calving, if it is right and good to feed the cow during the dry period. I also advise correctly and most importantly in time to launch, give the animal time to rest and accumulate forces. At the moment, also improve the nutrition of the cow, let's get more juicy feed and vitamins.
There are a few more reasons, although they are more concerned with a short-term drop in milk. But they are also worth considering just in case. A change in temperature, a change in daily regimen, and stress can adversely affect milk production. The lack of exercise, walking in fresh air, and a lack of vitamin D can affect the appetite of the cows. These phenomena often occur in the spring. Get rid of worms, it can also cause poor appetite.
