Weaning pigs weighing about 15 kilograms adopt a three-stage feeding method, which generally achieves the slaughter standard of 100 kilograms in four months. The new method of fast fattening is introduced as follows:
Feed formula
The first stage feed formulation: feeding time 40 days. The standard finishing weight ranges from 15 kg to 30 kg, corn 30%, bran 15%, dried potato 15%, vegetable cake 8%, fishmeal 8%, salt 0.5%, fine rice bran 30%.
Second stage feed formulation: feeding time 40 days. The standard finishing weight ranges from 31 kg to 50 kg, corn 20%, bran 10%, dried 20%, vegetable cake 10%, fish meal 1%, bean cake 4%, fine rice bran 35%.
The third stage feed formulation: corn 25%, bran 15%, dried 25%, cabbage 5%, fish meal 2%, salt 1%, fine rice bran 27%.
Feeding management
Insecticide and stomach fattening pigs were dewormed before entry into the pens, and the pig's ear was rubbed with insect repellent to drive off the parasites. It can also be fed into the feed at a dose of 1 gram of trichlorfon tablets per 10 kg of body weight. 20 grams of baking soda every 3 days, stir in a small amount of feed within the stomach, deworming stomach and then enter the fattening rearing.
The fermented feed is fed with copper sulfate, ferrous sulfate, and zinc sulfate in appropriate amounts. After being dissolved in warm water, it is uniformly sprinkled in the compound feed, and the appropriate amount of water is added to stir the mixture. After the handkerchief, the fingers are sew and see the water without dropping as the degree. Then Into the cylinder seal overnight fermentation. The so-fermented feed not only has the flavor of the wine, but also enhances the appetite of the pig, and the nutritional value of the feed after fermentation is effectively improved, thereby significantly improving the effective utilization of the feed.
Scientifically fed fermented feeds are fed raw and fed 4 times a day. The first feeding time is 6:30 in the morning. After about 4 hours feeding, the fourth feeding time is usually 9:30 in the evening. The amount of feed should continue to increase with the weight gain of the pig. When a pig weighs 15 kg to 30 kg, it feeds 1.25 kg of compound feed per day; when a pig weighs 31 kg to 50 kg, it feeds 1.25 kg to 1.50 kg of compound feed per day; when a pig weighs more than 50 kg, it feeds compound feed 1.75 per day. Kilograms, green feed is not limited. Less feed Tim, drink water after feeding. After 4 months, the fattening pigs will be slaughtered in a timely manner after reaching a weight of 100 kg, and they will no longer be able to continue feeding, so as not to affect the feeding efficiency.
