Adjustment of the strength of piglets

1. Separation of strong and weak, feeding in rotation on time Divide the piglets with good growth and strong physique into one column; divide the piglets with lighter weight and poor development into one column; at first, they can be packed in baskets and covered with straw and quilts in cold days. Piglets were fed in rotation every 1-2 hours; after 1 week they were fed in rotation every 3 hours and after 1 month they were fed in rotation every 4 hours.

Second, fixed nipples, eat good colostrum weak piglets because of limb weakness, mobility inconvenience, often can not find nipples in time, especially in the cold season, because the body frozen and will not suck milk. Therefore, at the end of the sow's delivery, put the weak piglets on the nipples with more milk in front, so that the strong piglets can suck the nipples with less milk and do not leave empty nipples, which can promote the development of sow mammary glands.

3. Early induction, 7 days after the birth of weaned piglets, feed can be used to induce food, feed will be placed in the palm, delivered to the mouth of piglets, let them lick food, 2~3 days later, piglets can eat freely in the trough. Feed should be dry feed, do not add water paste feeding, so as not to affect the effect. After feeding, clean drinking water should be prepared and allowed to drink. Warm water should be used in winter. The trough is separated by a wooden stick according to the number of piglet heads, so as not to compete for food into a strong sleeping trough. Sows postpartum 40 days, milk secretion gradually decreased. If the weight of two litters is different, the healthy and heavy litter can be weaned in the basket and fed outside the basket for defecation. Leave the weak litter to the sow for 15 days to achieve the effect of two litters of equal weight. Do not allow them to socialize within 2 months of division, so as not to bite.

4. Prevention of disease, injection of vaccine Within 30 days of piglet birth, 1~2 spoons of terramycin mixed with feed for sows every day can effectively prevent piglet white diarrhea. If piglet diarrhea is found, immediately use sulfamethoxazole tablets (SMT printed on the tablets)2 tablets finely ground with 2 tablespoons of water, generally 1~2 times to heal. When pouring, the pig will be picked up, clamped with both knees, take a thumb thick stick to hold it, and pour it in turn with a small spoon. Piglets should be injected once with the triple vaccine and piglet paratyphoid vaccine within 40 days.
