Do a good job of disease prevention in different production periods of pigeons
(1) lactating pigeons
Pay attention to the prevention of trichomoniasis. Trichomoniasis is mainly transmitted from parent pigeons to suckling pigeons directly. Check whether parent pigeons are infected with trichomoniasis, and if so, make timely treatment. Pay attention to the prevention of pigeon pox, pigeon pox is generally prevalent from March to June, it is necessary to do a good job of vaccination prevention and mosquito control. Once it happens, it should be treated by surgery in time. You can also spray a small amount of low-toxic mosquito-killing water on squab to prevent mosquito bites, but do not overdo it. In addition, attention should be paid to the prevention of coccidia, mycoplasmosis, salmonella and other diseases.
(2) breeding child pigeons
New child pigeons, because they have just left the parent pigeons, it is difficult to adapt to the changes in the environment, this is a greater stress, it is easy to induce disease, at this time can use some antibiotics for prevention. At the same time, some vitamins and mineral supplements can be added to improve the disease resistance of pigeons. In addition, do not suddenly change the feed formula, affecting appetite.
(3) Young pigeons during moulting period
At the age of about 50 days, @ 247 birds began to lose the first main wing feather, and then changed one every 13-15 days, continuing until the beginning of production. Molting is a kind of stress in pigeon production, which not only consumes a lot of energy, but also needs a lot of nutrition to make new hair grow. Therefore, it is most likely to get sick during the change of the first and second feathers. At this time, we should pay attention to supplement nutrition, increase vitamins and mineral trace elements, in order to improve the disease resistance of pigeons and reduce death.
(4) pigeons born during the pairing period
Once the breeding pigeon is successfully matched, it will be put into production immediately. Attention should be paid to increasing the content of protein feed before pairing, and some hemp kernels can be fed appropriately, which can improve the fertilization rate. A medicine bath should be taken before the start of production to kill external parasites.
Some antibiotics and insect repellents are given to enable breeding pigeons to be put into human production in good health.
