First, choose the right weaned piglets. Farmers who raise early weaned piglets should choose a weight of 6 to 8 kg for the purchase of piglets, and eat more than 200 g per head per day (can be judged from the condition of the excreta). The appearance is good, the spirit is good, the health is lively and the sound is crisp , normal feces, quarantine, and immune identification.
Second, the preparation of pigs and pigs. The position of the piglet barracks must be conducive to hygiene and epidemic prevention and feeding and management. The nursery bar should be divided into two parts, indoor and outdoor, and the indoor part should be equipped with a heat preservation room, a feeding trough and a bed, etc. The outdoor part should be provided with drinking water, shower facilities, a free sports field, and excreta and urine storage space. Two weeks before entering the pig, the pens must be cleaned, cleaned, and sterilized twice with two different disinfectants and left empty for later use.
When buying piglets, please inquire about the prevention of injections and feeding conditions. After purchase, piglets should be grouped appropriately according to sex and weight, with 10 to 20 heads per column, and each head occupying an area of ​​about 1 square meter. After the grouping, pigs must be fully sprayed with disinfectant liquid once, which can effectively prevent disease and avoid biting and stabilize the pigs. Then let the piglet drink the appropriate amount of electrolyte solution (25 g of glucose, 4.5 g of sodium chloride, 2 g of sodium bicarbonate, 0.3 g of citric acid, 0.2 g of potassium acetate, 0.05 g of potassium chloride, add water to 1000 ml) to enhance resistance. .
Third, pay attention to the use of full-priced feed. Feeding early weaned piglets must use weaning materials and reasonably use weaning materials to minimize piglet weaning stress, effectively prevent weaning and thinning, and promote normal development of digestive organs and immune organs.
Fourth, the use of two-stage restrictions on feeding. The nursery period of early weaned piglets was divided into two stages, weighing 6 to 12 kg and 12 to 20 kg, each of which lasted 2.5 to 3 weeks. The first stage was fed with weaning material (about 13.5-14 MJ/kg of digestive energy and 19%-20% of crude protein), fed 5 meals a day and fed once every 2.5 hours, and each meal was fed with 80% fullness. If you eat too full and easy to diarrhea. Feed the sucker feed (about 13.5 MJ/kg of digestible energy and 18% to 19% of crude protein) in the later stage, but do not change the weaning material directly to the feed of the sucker, but must start with the proper blending of the feed from the weaning material. Gradually realize the use of sucker feed instead of weaning feed. In the later stage, 4 meals are fed every day, and they are fed once every 3 hours. Each meal is fed immediately after eating but no food is left. Must be fed regularly to help digestion and absorption, and promote growth and development. General early weaned piglets at the end of the conservation period (ie up to 8 to 9 weeks of age), a body weight of about 20 kg, a weight gain ratio of 1:1.6 to 1.8, must be promptly slaughtered.
