Broilers grow poorly, compared to last year, they are like a different variety. They are 3 months old, and some weigh only 1 kg. We feed well, experience breeding is. What could be the reason? (Zinaida)
Hello. In principle, your situation is quite common. Of course, the first thing to do with poor growth is to sin on poor-quality feed, content, etc. But the reasons may lie in diseases and not necessarily infectious. For example, chickens can not gain a living mass in the presence of internal parasites. Then the bird is lethargic, eats poorly and often vilifies. Also, some solutions are described in this article.
What is the matter?
But there are no complaints from you on the health of birds. So, they are all right, although anthelmintic for prevention still need to be applied. Therefore, I believe that you just bought another breed or cross broilers. Not all meat birds develop equally. Some very quickly, others gradually. Maybe your birds of another cross, which is slower, but also more productive.
It is likely that at the poultry farm or at the breeder where you took the birds, this year there was a desire to experiment. Therefore, they crossed the breed last year with the other, which they considered necessary for their productive qualities. Now the birds are growing more slowly, but perhaps more tenacious or will have more weight in the end. You can find out this only by checking with the seller.
It is also possible that you did not buy broiler breed at all, but, for example, meat and egg. In the end, their weight will be the same as that of broilers, but they will add twice as long. This is possible if the seller is dishonest. So it is not always food and disease become the fault of the slow growth of the bird. You can also read our article on feeding and growing broilers here, here and here. Perhaps you will emphasize something new.
