Early weaning feeding and management techniques for piglets

Early weaning of piglets is an effective measure for tapping the potential for sow production in modern pig production and increasing the economic efficiency of raising pigs. However, the growth rate of piglets after weaning is accelerated and the requirements for feeding and management are relatively high. Therefore, in the entire breastfeeding and conservation period, it is necessary to implement supporting management techniques and requirements for housing. In the sow pens, separate feeding rooms and warming rooms are separated, and only two piglets are allowed to freely access. Second, insulation. Piglets should pay attention to insulation throughout the lactation period. Room temperature can not be lower than 20 °C, especially in the first 3 days of piglet production, the temperature should be maintained at about 28 °C, the daily temperature difference is not more than 2 °C. The newly born piglets should be kept warm in the incubator (room), and the feeding should be regularly released to allow the piglets to eat colostrum in time. Third, iron supplement copper. Newborn piglets are prone to iron deficiency anemia. Therefore, iron should be supplemented within 2-3 days of piglets birth to promote piglet growth. The method is: dissolve 2.5g of ferrous sulfate and 1g of cuprous sulphate in 1000ml of water and put it in a bottle with a spout. Drop it on the sow's nipple and let the piglets smoke or directly drip into the mouth of the piglet 1-2 times a day. Feed 10 mg per piglet per day. Fourth, make up replenishment. After weaning, the growth of piglets is very rapid. At the age of 2-4 weeks, the nutrients provided by breast milk can no longer meet the needs of its growth, so it is necessary to supplement the water in time. At the same time, supplementation can reduce feed conversion stress after weaning. Therefore, suckling pigs should be lured by 5-7 days of age. Every day and afternoon, the whole piglet pellets or self-contained feed is applied to the mouth of the piglet. After the piglet is used, it feeds itself in the feed room. Feeding times: The artificial forced tame of 5- to 7-day-old piglets is used 2-4 times a day, and the animals are trained 1 to 2 times in the afternoon and after; the material is placed in the feeding room and the feed is provided for 2 hours in the afternoon and after. Because the suckling piglet itself needs a large amount of water, plus 5-7 days of feeding, easy to dry mouth tongue noise, so from the 3rd day of age should be set piglet drinker (device), to provide clean drinking water, so that piglets follow drink. Fifth, grab food. After the suckling piglet starts to eat on the trough, the weight gain and feed intake increase as the digestive function is gradually improved. This is a critical period for accelerating the growth of the piglet. To this end, it is necessary to grasp the busy food of the piglets, and in addition to increasing feeding during the day and increasing the number of feedings, feed 1 additional time around 1am to fully meet the growth needs of the piglets. Full-price piglet pellets are used. If self-prepared feeds are used, a little pig fat (oil) should be added and supplemented by 25 grams per head per day. To increase the smell of feed, enhance palatability, and increase feed intake. Six, control the weaning age. It is better to control the age of piglets at 25-30 days. Should not exceed 35 days of age, otherwise affect the sow heat. When the piglet is about 15 days old, it is necessary to control the time spent with the sow, and the mother and child are separated at the age of 20 days. Seven, disease prevention 1, always pay attention to the sanitation of the house, regular disinfection. 2, in the feed to add digestive disease prevention drugs. Early weaned piglets are most prone to indigestion and cause bacterial diarrhoea. In addition to controlling the amount of feed during weaning, antibiotics should also be injected into the feed. (1) Add tetracycline or oxytetracycline to piglets, add 2-3 kg per 100 kg of feed for four to five days; (2) add baking soda to sow feed before weaning, which can improve feed palatability, Increased feed intake for sows can also prevent piglet blight and the sow's postpartum dyspepsia syndrome. Addition method: the sow on the first day of postpartum is sow in the sow diet by mixing 30 grams twice a day into the feed. 3, in order to prevent piglets yellow and red warts, 10 to 20 days before birth in the sow neck subcutaneous injection of Scutellariae vaccine or yellow Scorpion double vaccine. It can effectively control diarrhea in piglets. The newborn pigs are fed with green and streptomycin, each with 2000 units, orally 3-4 times, and even served for 3 days, which can achieve 90% or more of the disease prevention effect. 4. In order to prevent the infection of swine fever virus, pigs were vaccinated with swine fever vaccine after being produced. That is, 1 ml of attenuated vaccine for swine fever was given to each piglet after birth, and the piglet sucked the colostrum half an hour after injection. This method of immunization can overcome the interference of maternal antibodies and enable the piglets to be actively immunized as soon as possible to protect the piglets during lactation from swine fever virus infection.
