Nursery pig rearing management is an important part of the problem of farm management. To put the conservation of pigs into proper place, and to achieve the purpose of improving quality and efficiency, it is imperative to use talented people to be smart and strong, to select seeds for excellence, and for breeding to be intensive and cost-effective. In more than 20 years of production practice, the author has worked out a set of effective sow practical fine-feeding techniques. The key points are introduced as follows.
Objectives: The survival rate is above 98%, the incidence is below 3%, and uniformity is maintained.
1 Method of weaning: “Migrate the mother†(to remove the sow and leave the piglets) Method Weaning, keep three unchanged after weaning: no change; constant circle;
2 Strictly sterilize: After the nursery is thoroughly cleaned and sterilized, it is strictly sterilized. The ground can be selected for flame or spray disinfection. The space can be selected for fumigation. Then the pigs are allowed to enter the pigs for a period of time. After entering the pigs, the pigs are sterilized once a week. .
3 Transfer to groups: try to implement the "all-in, all-out," feeding method, with 10 to 30 heads per column, and 0.2 to 0.3 M2 per head. The transfer is best performed in the evening. When entering the group, try to keep the original circle in the same column. Regroup the groups that are not evenly distributed within the group, especially for excellent feeding.
4 Gradual refueling: continue to eat piglet pellets after weaning, and to control feed intake, 7-80% satisfies; after 45-50 days of age, it is gradually replaced with high-quality premixed or concentrated feed. .
5 Environmental requirements: weaning a week of humidity is 55% ~ 65%, the temperature should reach 27 ~ 25 °C, then the weekly decline in 2 °C gradually reduced to 10 weeks of 21 °C, the smaller the temperature difference between day and night the better, while preventing thieves .
6 Feeding methods: Feeding tank feeding method depends on the tank feeding, adding little to ground, adding 2 to 3 batches of material every day, and adding a little leftover material after the food is full; adopt automatic barrel feeding method. , to keep the material inside the barrel.
7 pay attention to drinking water: drinking water can be tap water or deep well water, the best way to use nipple drinking (height: 25 ~ 35cm), a single water tank, in order to facilitate the administration of drugs; use sink water, pay attention to constantly change the water, keep the water clean and sanitary.
8 Disease Prevention and Control: Pay attention to the elimination of “four pestsâ€, namely mosquitoes, flies, mice, and wild cats, cut off the spread of diseases and ensure biosafety. Do a good job of immunization and deworming work on time, focusing on the prevention and control of gastrointestinal and respiratory diseases, especially Haemophilus parasuis, edema, streptococci, and infectious pleuropneumonia. Improve the body's immunity and disease resistance, taking into account anti-virus, anti-bacterial and anti-stress, reduce the occurrence of digestive tract and respiratory diseases. And you can choose to feed it continuously for 1 week below. Fang Yi, 6% tilmicosin 1000g per ton of material, 200mg of doxycycline, astragalus polysaccharide 500g; Fang II, 80% of the original net in each ton of material 125g, chlortetracycline 2kg, amoxicillin 2kg; Fang San, according to the instructions in drinking water plus electrolytic multidimensional, astragalus polysaccharide powder and Zhiyuan net. Immunity: 60 days of piglet use spleen lymphocytic intramuscular injection of 1 head; foot-and-mouth disease intramuscular injection of 65 days old 2mL; pig erysipelas 70 days intramuscular injection of attenuated vaccine 1 head.
9 Observe the pigs: Check the intake, drinking water and health status every day, and treat the sick pigs separately.
