How to Improve the Performance of Sows backyard
The current decline in production performance backyard sow, sow abortion, premature birth, stillbirth and other phenomena produced more than a place, therefore, strengthen the sow feeding and management, improve sow performance,[link widoczny dla zalogowanych], to promote pork production and improve the breeding efficiency is of great significance. A good species to choose different varieties of local reproduction is not the same as the first female with Yorkshire, reproductive performance, litter size and more, breast-feeding ability, rapid weight gain,[link widoczny dla zalogowanych], postpartum estrus early, is a very popular with the majority of varieties farmers welcome. 2 elected to remain farmers gilts gilts to stay the election, choose motherhood is good, docile temperament, litter and more good quality milk (thick milk) is reserved for future generations sows gilts. When the piglets 28 to 30 days of age, piglets in the litter pick in the same athletic, nipple 7 to 8 on the beat Aberdeen sows ear tag, reserved for gilts. 3 pregnant sows are kept empty Management empty 3.1 Control Biaoqing pregnant sows and gilts before mating period, Biaoqing can not be too fat, too fat and fat sow ovaries were wrapped, easy to cause delayed estrus, or heat when ovulation less, or even just heat not ovulation. Thus, the body condition sows had caused repeated with fat is one of the causes of infertility, therefore, air must be kept pregnant sows breeding good body condition. 3.2 to ensure that pregnant sows nutrient supply air must ensure full supply of nutrients, dietary protein should account for 12% to 14%, if the supply or quality of the incomplete development of the egg cell is limited, reducing the number of ovulation, conception rate declined. In addition, to meet the needs of minerals and vitamins, especially calcium and vitamin A, vitamin D supply, to keep the air pregnant sows energy. 3.3 Short-term superior feeding of pregnant sows Biaoqing less air can be carried out before mating, \In the breeding, give the sow added β-carotene, vitamin E and selenium,[link widoczny dla zalogowanych], in order to increase litter size. 4 timely breeding gilts 7 to 8 months of age reached 120 kg body weight of mature, breeding should not be the first time in heat, 2 to 3 times in order to be breeding during estrus. Sows generally 5 to 10 days after weaning estrus, farmers should observe the dynamic behavior of sows. Found to sow appetite, behavior is relatively quiet, with both hands, press the back vigil fixed, receive boar Pa Kua should be timely breeding. Complex but also improve the conception rate, litter size increased an effective way to improve the complex index, with infertility of sows repeatedly to receive good results. 5 pregnant sows pregnant sow feeding and management does not require high levels of nutrition, but must be full price, in the green roughage-based conditions, according to the characteristics of pregnant sows and circumstances, the use of different rearing methods. 5.1 grasping the middle of two consultants for sows after weaning Biaoqing poor, to enhance nutrition in early pregnancy, allowed rapid recovery of body condition, properly fed in the feed corn, soybean meal and other fine materials, protein content accounted for 13% of dietary 15%. 4 to 12 weeks of pregnancy, sows digestion enhanced green fodder to the main dietary protein content accounted for 11% to 13% until 80 days after pregnancy, and then concentrate feed, when rapid fetal development, requires a lot of nutrition to meet the nutritional needs of female earners, the protein content of diets to account for 15% to 18%. 5.2 After the fine before the rough good body condition for breeding sows, early pregnancy and more feed green forage, late pregnancy (12 weeks), plus fine feed materials, such as corn, soybean meal, protein content of diets to account for 15% to 18%. 5.3 feed less frequently in the prenatal weeks pregnant sows Tim, weakened digestion, digestible diet should be fed, and fed with juicy green feed, so feed less frequently add, prevention sow constipation. 5.4 Baotai tocolysis lap pregnant sows to be kept and shelter should be flat, health, cool and quiet environment. In the first 1 month of pregnancy, make the sows eat well, sleep well, lack of exercise, after exercise should be increased, with particular attention to heatstroke, because in the summer of pregnancy, litter size of sows producing stillbirth, miscarriage more likely to large. 21 days before giving birth, sows easy to abortion, during which sows should stop exercising, while strengthening the fetus protection measures, the supply of protein,[link widoczny dla zalogowanych], minerals and vitamin-rich concentrate and green succulent feed, if any, signs of abortion are injectable luteinizing ketone 15 to 25 mg, and oral administration of sedatives to tocolysis. 6 putting prevention first, prevention is more important than the principle of rule 6.1 strict quarantine gilts at 20 days of age related to the first live vaccine against swine fever-free, 60 days to strengthen the immune 1, every 6 months after immunization 1; pig reproductive and respiratory syndrome vaccine-free in the first 21 days, 28 days after the first immunization to enhance immunity 1, every 6 months after immunization 1; porcine parvovirus vaccine in vaccination 20 days before mating 1 times; in the summer for 45 days before the arrival of Japanese encephalitis immunization attenuated, the interval of 14 days to strengthen the immune 1, after 1 year immunity. Pregnant sows in the air in time injection of porcine parvovirus and pseudorabies attenuated vaccine; 28 days postpartum injection of porcine reproductive and respiratory syndrome vaccine; injection of Japanese encephalitis in the attenuated before mating, interval of 14 days to strengthen the immune 1, after 1 year immunity. At the same time sows postpartum IM penicillin, streptomycin, or feeding enrofloxacin, use 3 days to receive good results. 6.2 The importance pens daily hygiene, disinfection should wash clean the inside and outside the sheds, pens to keep the health, clean. Work conscientiously eliminate mosquitoes in summer. For shelter, breeding sites for drug rotation spraying disinfectant to prevent the spread of the disease.
