Sub-sweeping pigs entering the nursery in the spring have strict requirements on the environment and feeding and management measures. Production should pay attention to the five aspects of work to ensure the survival rate of the pigs.
Environmental disinfection
Adhere to the all-in, all-out feeding system. Before weaning the pigs, we must clean the nursery houses, install drinking fountains, feed troughs, etc., and repair damaged windows, pigs, pigpen, ceilings, walls, floors, and passageways. , sewage drains, etc., and thoroughly cleaned, washed with high pressure water gun 2 times, and then dried with bacteria or perchloric acid disinfectant and other disinfectants repeated 3 times a day, empty for 3 days into the pig.
Group adjustment
When the pigs enter the nursery house, they must be divided according to their mother and mother, size, and strength. There should not be too much difference in age, and it is best to control within 7 days. If we can better press the original nest group, it will help stabilize the mood of the pigs, reduce stress, avoid bullying, and fight each other to cause harm. The breeding density is preferably 20 to 25 heads per column, with a small number in summer and a moderate increase in the number of cold winters so that the pigs can warm each other, but it must be ensured that each head has an activity space of 0.6 to 0.8 square meters. The training of the pigs is mainly to train the pigs to “determine three points†for defecation, feeding and sleeping, which is conducive to keeping the ring dry and hygienic. One to two iron chains are hung in each column for the pigs to play, which can avoid the occurrence of evils such as tail biting and ear-biting.
Reasonable diet
The piglets were weaned, and acidifiers, prebiotics and xylo-oligosaccharides were added to the weaning materials to promote digestion and prevent diarrhea. The feed replacement should have a 10-day adaptation period, reduce the pig feed by 10% per day, and increase the weaning material. In the early stage of childcare, multiple meals and less food can be used. Feeding 5 to 6 times a day, each time is suitable for 70% to 80%, and after 14 to 21 days, the number of feedings is gradually reduced, and gradual transition to free intake is achieved. After the transition from liquid milk to solid feed, the water demand of the pigs is greatly increased. The lack of water in the pigs makes it easy to drink urine or sewage and cause digestive tract infections. Therefore, it is necessary to provide adequate and clean drinking water for the pigs in the nursery period. .
Prevent stress
In the nursery period, the immunity of the piglets was low, and there were many stress factors in the nursery period. Therefore, the pigs responded to stress more strongly. In order to control stress, we should try to keep the original group unchanged and make it easy for the pigs to feel dependent. When groups must be mixed, they must be demolished without dismantling and dismantling. Keep the environment around the nursery quiet and avoid sudden noises. The adjustment of living habits requires patience and can't be beaten. When encountering abrupt changes in the weather, it is necessary to take precautions as soon as possible. Care must be taken to take care of them carefully. Observe carefully and find out that the pig fight should be stopped in time.
Control disease
During the nursery period, the piglets grow rapidly, their appetite is strong, their internal organs are overburdened, the active immune system cannot develop synchronously, maternal antibodies decline rapidly after weaning, the body resistance is relatively poor, and multiple diseases are prone to occur. The main measures to control the disease are to strengthen the management of feeding, and at the same time, timely vaccinate according to the characteristics of the local epidemic. The main infectious diseases that need to be prevented are mainly swine fever, blue ear disease, pseudorabies, gasping disease, paratyphoid pig, and chain disease. Coccyosis and so on. Five days after the pigs were transferred to the finishing houses, 400 grams of Fluconazole, 500 grams of astragalus polysaccharides or Radix is ​​added to 1 ton of feed and fed continuously for 10 days. Or add 1 kg of Licorcin and 200 g of amoxicillin to 1 ton of material and feed it continuously for 10 days to effectively prevent the occurrence of infectious diseases.
