Selection and purchase of fattening Pig Seedling how to choose good Pig Seedling

   generally selects pig fry (weaned piglets) for the purpose of fast growth, easy to eat, save feed, strong adaptability, disease resistance, high lean meat rate and so on. How to choose a good pig fry, please pay attention to the following points:

   1. To select lean hybrid pigs: hybrid pigs have the potential of high vitality, strong adaptability and heterosis. Hybrid pigs should be purchased according to their own feeding conditions, and ternary hybrid pigs can be purchased with good feed. The feed condition is poor, the binary hybrid pig contains more blood of the local pig, about 50%, so it adapts to the local environment and feed conditions, and is easier to raise. Considering the growth rate, feed return rate and lean meat rate, the ternary hybrid is better.

   2, depends on body shape and appearance: generally, pigs with long waist and slightly higher limbs are mostly lean pigs with plump buttocks and stout limbs. In appearance, it depends on the situation of specific crossbred pigs. White-haired hybrid pigs are generally crossbred with Landrace, Yorkshire and large White or with local pigs. The hybrid offspring of Landrace pigs: capillarity, long mouth, slightly larger ears and tilting forward; the crossbred offspring of Yorkshire pigs have longer mouths and moderately oblique ears; the hybrid offspring of large White pigs are similar to those of Yorkshire pigs.

   3. Choose healthy pigs: it is very important to choose healthy pigs, which is the key to the success of raising pigs. Healthy pigs have good eyes, bright hair, exuberant spirit, lively and agile, wagging head and tail, clear cry, etc., but also can be carefully observed in combination with feces, not diarrhea, dung mass, indicating that pigs are healthy. On the contrary, depressed spirit, rough hair, hoarse voice, dry nose, diarrhea or small dry pimple feces, indicating that there is something wrong with the pig.

   4. Choose pigs in the same litter: if you buy several pigs at a time, at least 2 or more pigs should be selected in the same litter, because they have common living habits, raise in the same circle, grow fast, save feed, and manage the farm. Different litters of pigs with captive life habits are not coordinated, fighting, grabbing, chasing and biting, difficult to raise and difficult to manage, growth hindered and a waste of feed.

   5, nearby purchase: choose and buy pig seedlings on the spot, better understand the situation of pig herds in pig farms, reduce trouble, and buy pigs that are easy to raise and manage, because the climate, feed, environment and other parties are similar, it is best to go to the qualified pig farm to buy pigs from the original nest. Try not to buy pig fry on the market.

   6, buying pigs should pay attention to consanguinity: do not buy inbreeding, cross with pig fry, must maintain hybrid advantage, otherwise, the economy will suffer losses, pigs are easy to get sick.
