Dr. Yang: Hello!
My family is located in the southern mountainous region. The nearby hillside is rich in water and grass. It is suitable for the development of aquaculture. I have introduced a number of lambs suitable for cultivation in the south. But now it is hot summer and the temperature is too high. I do not know what precautions I have. Please introduce some sheep breeding in summer. technology! Thank you! Reader: Liu Liping
Liu Liping reader: Hello!
The south of China is hot and humid in the summer, mosquitoes and flies breed, and herds are susceptible to viral and parasitic diseases. Therefore, it is important to do a good job in the summer health care of the flock, prevent diseases and remove mosquitoes and flies. This is a key technical measure for raising sheep in the summer.
Sheep house disinfection
The sheds were sterilized and sprayed with 10%-20% lime milk or 10% bleach or 3% lisul or 5% ash or 10% carbolic acid aqueous solution; sports ground disinfection with 3% bleach or 4% blessing Oralin or 5% sodium hydroxide aqueous solution is used for disinfection; the doorway (inlet and outlet) is disinfected, sprayed with 2%-4% sodium hydroxide or 10% kelipin, or disinfectant is often placed at the entrance and exit. Sacks or mats; skin and mucous membranes are disinfected; use 70%-75% alcohol or 2%-5% iodine or 0.01%-0.05% neat to wipe off the water solution, rub the skin or mucous membrane; 1%-3% gentian violet or 3% hydrogen peroxide or 0.1%-0.5% potassium permanganate solution to wash the contaminated or suppurated area; sterilize the feces and use bio-thermo-disinfection method, that is, 100% away from the sheep house. In places other than rice, the sheep dung is piled up and covered with 10 cm thick fine soil and fermented for one month; the sewage is disinfected, the sewage is introduced into the sewage treatment tank, bleaching powder or quicklime is added (generally, 2-5 per litre of sewage g) processing.
Flock medicine bath
The medicine bath is built. The commonly used medicine baths are 0.6-0.8 meters wide, 0.3-0.5 meters wide, 1-1.5 meters deep and 3-10 meters long. Fences are placed at the entrance and exit, and the exit is paved at 1.5%. The slope drip flow station allows the goat medicine to stay for about 10 minutes after bathing to facilitate the return of the liquid from the sheep body to the pool.
With common liquid
Commonly used liquids include 0.1%-0.2% insecticidal fleas, 0.05% phoxim, 0.03% lindane EC, 0.2% insecticide net, 0.04% pyridin, and 0.05% pyridophosphate and oil emulsion bath (oil 75 Ml, caustic soda 27g, water 250ml, dissolve caustic soda with hot water first, add petroleum stirrer, add water 10 times dilution) and lime sulfur bath (take lime 7.5kg, sulfur powder 12.5kg, stir into paste with water In the form, add 150 liters of water, stir until boiled until dark brown, discard the sediment, the supernatant is the mother liquor, add 500 liters of warm water to the mother liquor, and it becomes the medicinal bath liquid).
Medicated bath
Medicinal baths should be done on sunny days. Stop grazing or feeding 8 hours before the medicinal bath. Drink plenty of water to the sheep 2-3 hours before bathing to prevent the sheep from swallowing poison in the medicine bath. The temperature of the liquid should be around 30°C. Bathing healthy sheep first, after bath with skin disease sheep, disease, injury and pregnancy more than 2 months of sheep should not be a medicinal bath. The depth of the bath is suitable for immersing the sheep. Goats are always on the line. The bath time of each sheep is not less than 3 minutes. The sheep's head should be pressed into the liquid 1-2 times. After the medicinal bath, drain the sheep body on the drip table and let the sheep rest in the shade and in the pens. 6 hours after the medicinal bath, feed grass or grazing can be given.
Deworming for sheep
If the spring is too late to deworm, you should repel the insects before summer grazing. Commonly used anthelmintic drugs and oral doses per kilogram of body weight are: 15-20 mg of albendazole, 8 mg of levamisole and 0.2 ml of extermination. When using anthelmintic drugs, accurate measurement is required, and a small group of deworming tests should be conducted first, followed by deworming.
Immunization
At present, China's vaccines for the prevention of goat infectious diseases include: No. II anthrax spores, Brucella-type No. 2 attenuated vaccines, tetanus alum-like toxins, tetanus antitoxin, and sheep quadruped vaccine (prevention of sheep epidemic, Colonization, enterotoxemia, and shepherd's fleas) Lamb dysentery vaccine, goat infectious pleuropneumonia aluminum hydroxide seedlings, mycoplasma ovipneumoniae inactivated aluminum hydroxide vaccine, sheep embryo attenuated virus vaccine, and Streptococcus suis aluminum hydroxide Miao et al. All immunizations should be carried out according to scientific and reasonable immunization procedures. It is recommended that technical personnel from the local animal husbandry and veterinary department should perform the procedures.
Feeding summer health medicine
For prevention of health care, the sheep can be fed with summer health medicine. For example, 25 grams of pollen, 25 grams of forsythia, 25 grams of Coptis, 25 grams of astragalus, 25 grams of astragalus, 25 grams of medlar, 25 grams of turmeric, and 15 grams of licorice were taken together after powdered in. If there is a dung-dry sheep, add 10 grams of nitric acid, 25 grams of rhubarb, and 30 grams of two ugly, and take them together with the above drugs.
