The right choice of fattening piglets to choose piglets in the bazaar or on the farm should be "eight to two questions":
A look of fur, bright, ruddy; 2 look at the eyes, asking God, no eyelids; 3 look mouth and nose, require a short mouth flat, large nostrils, moistened nose; four look body type, requiring long back waist, chest width and deep; Five to see four hoofs, requiring four hoof health, tidy; six to see the tail, requiring freedom of movement; seven to see the anus, requiring clean and no dirt, dirt; eight to see the activities, require freedom of movement, have a strong appetite.
Second question: When asked about the variety, it is best to choose a good breed of cross-breeding piglets. When asked about epidemic prevention, do not buy piglets from the affected area and understand what kind of vaccine was injected.
Before finishing fattening, immunization, deworming, gastric lavage, and stomach-enhancement work should be performed with 1 injection of the vaccine (commonly used for swine fever--porcine erysipelas combined vaccine) on the return of the piglets; on the 2nd day, the worms are killed with levamisole or propoxylate. The imidazole tablets were mixed with 25 mg/kg of pig weight into the feed to drive off the parasites. The surface of the pig was sprayed with 3% to 5% of trichlorfon solution to drive off the ectoparasites. On the 4th day, gastric lavage was performed for 2 consecutive days. On the 6th day, the stomach was treated with rhubarb soda (2 tablets per 10 kg) and fed into the feed three times.
Adopt reasonable nutrition and scientific feeding and management measures. During the rearing of finishing pigs, it is best to raise in two stages according to body weight (25 to 60 kg in the pre-fatation period and 60 to 100 kg in the later period), and select the local feed resources according to the nutritional needs of the pigs. Use concentrated premix to mix the full price diet for pigs. In the management of pigs: First, do a reasonable grouping, generally 10 to 20 heads per lap is appropriate, to ensure that each pig has a suitable field area (usually 0.4 to 0.8 square meters in the early fattening period, later 0.8 to 1.2 Square meters/head) and keep the weight of the pigs in the same column. The second is to do a good job of pig "three-point positioning" training, so that the pigs from the beginning to develop a fixed place defecation, feeding and sleeping habits. The third method is to adopt raw material wet feeding and drinking water alone in the feeding method. Powdered batch materials are prepared by adding water at a ratio of 1:1 to 1:1.5. The fourth is to establish a regular and quantitative feeding system. In order to promote digestion, improve feed utilization rate and growth rate, finishing pigs' daily diets can be fed at regular intervals of 3 times. The daily feed supply per pig can be quantified at 3.5% to 4.5% of the pig's body weight. In addition, the appetite of pigs is generally the highest in the evening, followed by the morning, and the weakest at noon. Therefore, the amount of feed each time during the day can be roughly distributed at 35% in the morning, 25% at noon, and 40% in the evening.
