Winter raising of fattening pigs is the period with the worst environmental conditions, greatest harm, and most difficulties during the year. If feeding and management can not keep up, pigs do not grow long, and even drop out. Therefore, we must improve the environment and conduct scientific breeding. The main measures are as follows: Before the sheds are sterilized into pigs, the pighouses and foodstuffs shall be thoroughly cleaned, rinsed and disinfected. The walls shall be painted and then sprayed with 2% caustic soda solution to eliminate the epidemic and prevent the infection. Hybrid pigs are selected to use hybrid boars and local sows for binary or three-way hybrids to produce fine hybrid pigs for fattening, which can be slaughtered 7 to 10 days earlier than the native pigs, with high returns, good meat quality, and good economic returns. . The boar that decides to fatten before fertility should be cast off before and after 25 days of age. Pig Yi Baoding, less bleeding wounds, healing faster. Castrated pigs are docile, well managed and grow fast. Otherwise it will affect the fattening effect. Because the sows are slaughtered early and do not affect fattening, direct fattening may not be done. Pigs are most likely to be infected with parasites during the rearing period. Deworming can be levamisole or ivermectin. The pigs should be given medication on an empty stomach in the morning. The body and excrement laid down are collected at any time for accumulation and fermentation to prevent reinfection. Intensity Fattening Winter is cold. In order to improve the cold resistance and weight gain rate of finishing pigs, the energy level of the diet can be increased, and the digestibility per kilogram of the diet should be 11.9 to 13.3 MJ. The energy should increase gradually. The protein level can be increased to 17.5% correspondingly. After grasping the high and low levels, a higher daily gain can be obtained. It is also necessary to satisfy the actual requirements for minerals and vitamins for finishing pigs. It is best to use straight-line fattening method for finishing pigs, feed nutrient-rich feeds from weaning to slaughter, so as to give full play to their growth potential, and obtain higher daily gains, making them weigh up to 100 kg at 6 months of age. Management requires darker lighting and proper reduction of pig movement. Pay attention to the method of feeding, especially in the late stage of fattening, more than an unlimited amount of feeding method to facilitate fat deposition and weight gain. Pigs eat much more quickly, and can shorten the fattening period. When it is found that the feed intake of fattening pigs increases and the slaughter rate is high, do not raise them again. Keeping the insulation warm in the winter is long and cold in the winter, which is not good for raising pigs. Therefore, grasping insulation is the guarantee for raising pigs in winter. It is necessary to repair the insulation ring, thicken the ceiling, block the north wall, close the doors and windows, and hang the grass curtains at night to reduce the pig's maintenance consumption, promote the pig's rapid weight gain, and improve the wintering effect of the finishing pigs. The prevention of the disease is a threat to the production of fattening pigs, and it focuses on the prevention of infectious diseases. Periodically deworming and housing disinfection, timely control and discovery of the epidemic, so that early prevention of disease-free, disease early treatment to ensure the normal production of pigs.
