1. Look at the spirit, the spirit is lively, the eyes are bright, the tail swings freely, and the voice is crisp.
2. Look at the feces and pull the feces into a ball, soft and moderate, without mucus.
3. Look at the skin, the fur is ruddy, and there is no nipple erythema and ringworm.
4. Look at the appearance, there is no trauma or deformity.
5. Look at the variety. In recent years, it is common for Landrace pigs to cross with local sows to produce piglets.
Some of them crossed Duroc pigs with binary hybrid sows to produce ternary hybrid pigs. As a white-haired hybrid pig, piglets usually have the characteristics of capillaries, long mouths, slightly larger ears and flat forward. Slender waist. The crossbred piglets of about 100 grams have a slightly longer mouth, moderately inclined ears and a slightly thicker and longer body. The black spots between the fine brown hairs are Duroc hybrid piglets. Binary hybrid pigs have strong adaptability, fast growth, high lean meat rate and good sales. Ideal to buy. Three-way hybrid piglets, containing less local pig blood, have high requirements and are difficult to raise. But lean meat, fast growth, good conditions, raising ternary hybrid piglets.
6. According to the body shape, generally choose piglets with wide mouth tube, deep fork, wide forehead, big eyes, thin auricle, hard ears, flat and wide back with double ridges, thin and elastic skin, slightly thin and shiny hair, long waist, deep chest, hip breadth and slightly thick limbs.
7. Look at the source of piglets, understand the source of piglets, and see if they come from non-epidemic areas.
8. Look at the quarantine certificate. In recent years, veterinary departments all over the country have attached great importance to quarantine work. Piglets are subject to epidemic prevention according to regulations and quarantine before transportation. When buying piglets, you can check the quarantine certificate with the owner. Second, the selection and fattening of piglets should be based on the situation. When determining the pig-raising project, we should analyze the market development situation, properly grasp the scale of pigs according to our own financial resources, material resources and technical level, and must not blindly develop. When the feed price is stable, buy piglets to fatten. When food prices rise in the short term and the price of fat pigs is good, you can buy big piglets weighing more than 40 kg. Big piglets are relatively less sick and can be slaughtered quickly, which can improve their income.
Third, pay attention to the buying season.
The temperature rises gradually in spring, which is beneficial to the growth and development of piglets. In autumn, the temperature is suitable and the available feed is rich. We can seize the time to raise more pigs in these two seasons. When buying piglets, it is necessary to estimate the slaughter time. After the pig weighs 90 kg, it produces more heat and grows relatively slowly. Therefore, it is necessary to stagger the slaughter on hot and humid days. Fourth, change the custom of slaughtering fat pigs before the Spring Festival.
Some farmers are used to raising big fat pigs for the Spring Festival. At this time, there are many fat pigs on the market, which are often difficult to sell. It may not be bought until the fifteenth day of the first month. As a result, the feed consumption was high, the fat increased and the profit decreased after being raised for one month. We should change our customs, enter the market at the right time and leave the market at the right time.
