Winter is a key season for the fattening and marketing of mutton sheep. However, in the winter cold weather, the grass is yellow, if you do not strengthen the feeding and management, the fattening effect will be reduced. To finish fattening sheep, we should start from the following aspects: I. Preparation before fattening The sheep were subjected to a health examination to see if they had chronic diseases such as asthma or cough. The diseased sheep had to be treated before being fattened, and the sheep were managed and fattened by species, sex and individual size. Second, disease prevention and deworming As the weather gets colder, the resistance of the mutton sheep decreases and it is easy to get sick. Therefore, the flock that has not been vaccinated should be vaccinated in time, and it is generally inoculated with triple-four defense and foot-and-mouth disease vaccines. In addition, vaccines such as goat pox, infectious pleuropneumonia, and streptococcus should be considered based on the incidence of local mutton sheep. Conditional short-term mutton fattening farms shall adopt the all-in/all-out system. After a batch of sheep are slaughtered, they shall be sterilized with flame or 2% to 3% sodium hydroxide solution and then sterilized strictly before raising the next batch. The diseased sheep shall be found. Timely isolation and treatment to prevent infection. When grazing sheep are grazing in summer and autumn, parasite eggs may be eaten into the body and the eggs develop into adults in the sheep body. Therefore, the flock will be subject to preventive deworming in the late autumn and early winter. Broad-spectrum insect repellents (avermectin, albendazole, etc.) are commonly used to kill nematodes, aphids, and surface parasites. In addition, flukes such as Fasciola hepatica have to be driven with praziquantel, and they should be re-injected at intervals of one week in order to drive the net. The same flock should avoid using the same drug all the time, and timely cleaning and accumulation of excrement after deworming to kill eggs. Third, daily management Feeding sheep breeding density can not be too large, to ensure that 0.8 to 1 square meters / only, sports field 2 square meters / only, feeding slot length of 0.3 meters / only. It is necessary to clean the house or change the bedding every day to keep the sheep house clean and dry. Regularly sterilize the pens and feeding troughs and sterilize them with 0.5% peracetic acid solution or 0.1% sodium hypochlorite solution. Disinfection tanks and sterilizing passages can be installed in the sheep farm entrances and exits to reduce the entry of outsiders and vehicles and prevent the spread of the disease. The sheep's cold-resistant ability is relatively strong, but the temperature in the house should not be lower than 0°C. The sheep house should be inspected and repaired in time. If necessary, a plastic greenhouse can be set up to reduce the energy consumption for maintaining body temperature and improve the body resistance to prevent colds. And diarrhea. Forage-rich areas can be fattened by semi-grazing and semi-family feeding. When grazing, choose a meadow with good grass quality and leeward yang, so that it is better to grazing late and return to the grazing; do not grazing in moist and muddy places; prevent sheep from eating grass with dew or frost; prevent sheep from running around. Reduce physical exertion and play a fattening effect; breeders should observe the feed intake, rumination, and mental status of mutton sheep to prevent them from eating foreign materials such as plastic cloth and rope. Fourth, scientific feeding Sheep are herbivores, so the reserve of forage is very important. Corn straw, rice straw, soybean stalks, and peanut meal can all be used to feed sheep. By-products such as bean curd slag and brewer's grains, and green and juicy fodder such as carrots and sweet potatoes are good feed for fattening sheep. Unsilaged straw should be cut into small pieces less than 1 cm in length when fed. Corn silage silage is commonly used to feed sheep in northern China's agricultural areas. Practice has shown that high-quality corn straw silage combined with concentrate feeding can be used to fatten sheep. Dry corn stalks can also be alkalized, aminated and fed to increase palatability and digestibility. When feeding, it is necessary to ensure that the amount of hay or corn silage feeding, usually free to eat, to ensure that every sheep can feed. The fattening time of mutton sheep is about 60 days. Each sheep in the early period of fattening is fed with 0.3-0.5 kilograms of fine material per day and 0.5-0.8 kilograms at the late stage of the fattening. The energy concentration of the ration should be increased at the late stage of fattening (ie, the proportion of corn), but The rough ratio should not exceed 6:4. In addition, a certain percentage of premixes (such as trace elements, vitamins, growth promoters, etc.) must be contained in the meat sheep concentrate to increase the growth rate and resistance of the mutton sheep. The recommended formula for meat sheep fattening period is as follows. Take 100 kg as an example. Pre-finishing: 55-60 kg of corn, 10-15 kg of bran, 20-25 kg of pancake, 1 kg of salt, 1 kg of stone powder, hydrogen phosphate 0.5 kg of calcium, 0.5 kg of baking soda, 1 kg of premix; fattening period: 65 to 70 kg of corn, 5 to 10 kg of bran, 15 to 20 kg of cake, 1 kg of salt, 1 kg of stone powder, calcium hydrogen phosphate 0.5 kg, 1 kg baking soda and 1 kg premix.
Health foods contain a certain amount of functional health ingredients, which can regulate the functions of the human body, have specific effects, and are suitable for specific groups of people. General food does not have specific functions, and there is no specific range of people to eat. Health food cannot be directly used to treat diseases. It is a human body mechanism regulator and nutritional supplement.
