Pig breed improvement Selection of well-developed, robust and lively hybrid piglets for fattening is best done by the use of binary mother-dwelling pigs from Landrace, Duroc and Yorkshire pigs and Duroc hybrids such as Sanyuan pigs. Fast growth, high lean meat ratio, and high meat and meat ratio. When the weaned pigs are fed for 80 days or more and the body weight is 60-70 kg or more, the insecticide-removing, stomach-enhancing, and supplemental feeding measures are used to fatten the body for 20 days and the body weight can reach 90 to 100 kg. Owning fine boars and breeding sows, breeding their own hybrid piglets, and breeding their own commercial pigs are conducive to epidemic prevention, increasing the survival rate of piglets and reducing the cost of raising pigs.
Deworming regular piglets 60 to 70 days after birth, an insect repellent, gastric lavage, stomachic, two months later repeat again. Methods: On the first day of deworming, feed 1 piece of animal trichlorfon tablets at 2.5 kg gross weight. Deworming works better at night from 7 to 8 o'clock. Before the medicine is given, let the pig stop eating. When the medicine is given, dissolve the tablet with warm water and mix it in a small amount of feed to allow the pig to eat once. On the third day, gastric lavage was performed, 15 grams of baking soda (pig reduced) and fed into the breakfast feed. On the fifth day, take another stomach, ie, use rhubarb soda, and use 1 tablet per 5 kg gross weight. Mix three meals a day and feed into the feed. On the 7th day, add 1 kg of amaranth and 300 ml of white sugar. Feed 2 to 3 times. Then start the feed with additives.
Feeding time feeding adopts dry-wet method, that is, dry feed is fed with wetting and softening, and it is necessary to regularly quantify and feed 4 meals a day. Its softening method is very simple, the ratio of material and water is 1:1. The time for soaking and softening can be determined according to the temperature. When the temperature is lower than 10°C, it can be soaked for 4 to 5 hours in advance; when the temperature is higher than 10°C, it is soaked for 2 hours in advance. When feeding, it is usually required to feed at 7:30 in the morning, 11:30 in the afternoon, 3:30 in the afternoon, and 9:30 in the evening. The feeding amount is 50% of the pig's body weight, and the pig eats until 89% full, and the tank does not contain any leftover material. Feed the concentrate before feeding the green material and give enough clean drinking water. Lack of water will affect the appetite, digestion and normal growth of pigs, and reduce feed utilization.
The feed must be very careful with the balance of various nutrients in the pig feed. It is necessary to choose the good feed of the regular manufacturers, plus corn, vegetables and grass for mixed feeding. In order to meet the needs of pigs for nutrition, the feed must use multiple feeds. The feed ingredients are generally 25% to 30% of corn flour, 25% to 40% of corn flour, 8% to 10% of peanut meal, and 10% of melon powder. ~ 20%, rice bran 10% to 15%, fishmeal 50%, salt 1%, shell powder 1%. However, add 1 pack (100 grams) of compound additive per 50 kilograms of mix, stir well, add water, and feed.
The fattening agent was added to the pigs every day for 20 days. Its formula is: salted fish, bone meal, bean cake, soybeans each 3 kilograms, lard, sugar each 1 kilogram, corn 7.5 kilograms, tangerine peel, malt 25 grams each, 10 grams of Divine Comedy. After frying the soybeans together with salted fish, corn and other materials, it is divided into 20 batches. Each pig is fed 1 part per day and is added to the diet in 3 batches. It can be slaughtered after 20 days of feeding.
The Raw Material is dry and fed except for a few cooked soybeans, the rest are raw materials, and the amount of feed per pig per day depends on the body weight; the body weight is 10 to 20 kg, and the daily feed is 1.5 kg; the body weight is 20 to 35 kilograms, 2.5 to 3 kilograms a day, 35 to 60 kilograms, 3.5 kilograms a day, and 4 to 5 kilograms a day for a body weight of 90 kilograms or more.
