Regarding Burna’s disease, a few years ago, one of my friends, who I think was Mr. Engineer Hosseinian, mentioned it to me.
According to the things I told you about the weakness of the immune system of birds involved in this condition (landing), any virus that can enter the bird’s body can multiply and cause disease due to the inefficiency of the immune system. Brena virus is not an exception to this rule, and if it enters the body and reproduces, it may cause disease. As a result, you have a bird that may also test positive for Brena, but again, the main cause of your flock’s problem is neither Brena nor Newcastle; Rather, the weakness of the immune system caused by malnutrition will bother your herd
Unfortunately, due to the low quality of micronutrients used in animal feed (which are mostly grade 3 and 4 Chinese products), the occurrence of these problems has become more apparent in animal husbandry units, especially ostrich breeding.
The reason for this is that the ostrich usually grows very fast, and because of the special conditions of its breeding, the possibility of access to fresh fodder in large quantities or other non-concentrate food sources is very limited, we have to cover its needs only manually, with Paying attention to things like the high price of inputs, especially the inputs that play a role in providing the protein needed by the bird’s body (such as soybean meal) as well as the microelements added to the feed, as well as the low quality of the microelements available in the market, the nutritional problems of farms have intensified in the last few years. And Ghariban does not leave the farmers
