Most areas in China are still very hot after entering the end of August. The main points for raising sheep are to keep the heatstroke cool, dry the hay, and pre-equip the ewes. After the summer heat, the temperature gradually decreased, and the weather became significantly cooler. The main points of raising sheep were the elimination of pests, the breeding of early breeding rams and ewe seduction, estrus identification and breeding.
First, heatstroke cooling. The most suitable life and production temperature for sheep is 8°C~16°C. When the temperature exceeds 30°C, the daily gain of mutton sheep and milk production of dairy goats are significantly reduced. When the weather is hot, the main reason for cooling the sun is to take the following measures: drinking enough water. To keep the sink fresh and cold, it is best to use groundwater, add a little salt to the water, and try to get a drink now. Adjust the diet structure. More feed green and blue juicy feed, dry straw feed, hay dry feed. The content of nutrients such as protein, vitamins, and minerals in the diet should be increased. Diet can add 0.5% sodium bicarbonate, in addition to the rumen to acid, prevent ketosis, fatty liver and other diseases, but also promote the respiratory heat. Night feeding. Due to the hot weather during the day, the sheep can be supplemented with forage grass at night when the weather is cool, so as to make up for lack of feed intake during the day. Increase ventilation. Open the door and window of the sheep house, and install electric fans with conditions to speed up the circulation of air in the house and reduce hot and stuffy or high temperature and humidity. Visor. Chaoyang Yangmeng the doors and windows, the application of asbestos tiles, fiberboard, plywood, etc. do shade; if the stadium without shade, application of reeds, wheat straw, straw, etc. set up pergola, so as to avoid the sun exposed to the sun. Sweep disinfection. Routinely sterilize and kill adulterants with 5% or more of the poisonous substances in their homes or abroad. Remove feces in time and fill the cesspits to reduce the interference of mosquitoes and flies. Drink dandelion water. Dandelion water has anti-inflammatory, bactericidal and heat-clearing effects. In the early fall season, the sheep is easy to get angry and cause eye diseases. You can often drink dandelion water and wash your eyes with dandelion, 3 times to 4 times a day.
Second, drying hay. Green hay has less water content, more dry matter, more nutrients, better palatability, and can replace green grass during the withered period. Sheep bred with high-quality green hay have a strong body and high yield stability. Therefore, we should make full use of green grass and hot weather to prepare enough hay for the dry season. In the drying of hay, the method of using straw to grind the green: Spread 1/3 m thick wheat straw on the big rice field, spread 1/3 m thick green grass on top, and spread 1/3 m thick on green grass. The wheat straw is then pressed with tweezers, and the outflowing grass juice can be absorbed by the wheat straw. The crushed green grass can be dried one day in the hot weather.
Third, pre-equiped ewes feeding. The peak period of breeding of common sheep is from late August to late October. Ewes can cause loss of appetite due to intense heat and prolonged lactation can lead to physical exhaustion and thin body condition. After the weather turns cold, along with the increase of appetite of the ewe, plus the flourishing pasture during this period, the nutrition is rich and the palatability is good. Therefore, timely utilization of favorable pasture and climatic conditions should be followed by short-term superior feeding of ewes between 20 days and 30 days before breeding to achieve full-fledged mating. Feed the ewes a sufficient amount of quality forage grass every day, such as alfalfa, Russian feed vegetables, grain mash, etc., and supply nutrients with a full-scale concentrate, about 0.5 kg per day.
Fourth, eliminate pests. The mosquitoes and flies can cause sheep nose fly disease. They can be used to apply trichlorfon ointment around the nostrils of sheep (1% refined trichlorfon waste oil or other oils, ointment) or 2% of the children's nostrils. Method of prevention. Grass creepers can cause sheep schistosomiasis, and can be treated with 0.5% to 1% solution of trichlorfon or 0.05% to 0.1% solution of rifampicin (rubber) solution every week.
V. Breeding of breeding rams in the early stage. The breeding of pre-breeding rams is critical to the success or failure of breeding. General species of rams feed 0.5 kilograms of concentrate from the beginning of late August, feed 1 kilogram of concentrate from the beginning of the summer heat, and supplement two raw eggs or 1 kilogram of goat milk each day. Premium forage grasses are allowed to feed freely.
Six, ewe induced, estrus identification and breeding. After the ewes in late August, sunshine began to shorten and the temperature began to fall when estrus began. There are a series of regular changes in the estrus's mental state, sexual behavior, and genitalia. The estrus identification should be performed according to the estrus estrus symptoms, and the estrus should be bred in time. Observe the ewes each morning and afternoon. To prevent misfits, it is best to use a ram to try and put rams that are physically strong and have sexual experience into the ewes and find that there are ewes that accept the climb. estrus.
