Breeders are always unable to avoid the infestation of parasites, especially free-range chickens, because they are outside all day long looking for food pits, and feces are everywhere, infected with intestinal parasites chickens pull out of the feces with insect eggs, pecked by other chickens and then infected with other chickens.
Chickens are also social animals, and they have a high degree of contact with each other, and the surface lice and mites will infect each other.
Chickens infected with parasites will generally show malnutrition, thinness, pecking, thinning, some of the more serious chickens appear thin bones like wood, chicken crown white, like to planing pit crawling me, resistance declines, and finally lead to death. The decline in egg production by layer chickens or even the suspension of production, the growth of broiler chickens is assisted, which seriously affects the ratio of feed to meat and lowers the economic benefits.
Chicken internal parasites mainly have coccidioides, tapeworms, nematodes, trematodes; body surface parasites mainly include mites, lice, etc., each parasite has its own mode of transmission and life characteristics, as long as we find their characteristics can be 'the right medicine'.
Like coccidioides mainly present in chicken feces and soil, especially the eggs in chicken dung are the main source of coccidiosis outbreaks, when the humidity in the environment is large, it is easier to erupt coccidiosis after rain. For the prevention and control of coccidiosis is mainly to give the chicken a dry environment, the construction of the chicken coop is very exquisite, drainage work must be done well, if there is a puddle on a rainy day, the chicken will go back to drink dirty water, especially in some rainy places in the south, coccidiosis is more rampant.
During the brooding phase, we try to choose a mesh bed to raise the chicks and separate the feces. Tapeworms, nematodes, their intermediate hosts are mainly ants, earthworms, grasshoppers, beetles, fly maggots, etc., also spread through feces, the control method is mainly to do a good job of enclosure hygiene, regular deworming.
Ectoparasites are generally mainly transmitted by contact, mites parasitize on the surface of the chicken or in the skin, causing chicken anemia, thinness, hair removal, easy to cause chronic dermatitis, resulting in chicken itching and itching, when pecking after bleeding will cause other chickens to pay attention to and trigger chicken pecking habits. Fleas live on the surface of the body and also live by sucking the blood of chickens.
Free-range native chickens are recommended to do in vivo and outdoor deworming every 45 days, and chicken brothers generally use albendazole ivermectin mixture for deworming. Albendazole has a wide spectrum of insect repellent activity, which has a good repellent effect on thread, taenia and trematode, while ivermectin has a strong repellent effect on arthropod insects, such as mites and fleas, and also has a certain repellent effect on nematodes.
Coccidiosis chooses sulfadioquinoline sodium, dikopramine premix, the specific dosage is determined according to the concentration of deworming drugs, but according to the experience of chicken brothers for many years, the dosage recommended by general drug dealers can not achieve good results, so the dosage will be increased.
