How to choose pig seedlings? How to improve the survival rate of pig seedlings?

Last year, under the influence of African classical swine fever, pork prices rose. This year, many farmers are very optimistic about the pork market, and as a result, more and more farmers raise pigs. Farmers want to raise pigs, the most important thing is to buy pig seedlings, generally speaking, normal pigs are born to out of the pen is about 6 months, the weight is about 120-130 kilograms. So how to choose the pig fry? How to improve the survival rate of pig seedlings? Next, let's have a look with the editor.

First, how to select pig seedlings?

Look at the shape of the mouth: the mouth is short and round, large and even, and the fork is deep, especially the jaw should be thin. Miao pigs with neat lower jaw and upper jaw eat more, are not picky about food, are easy to raise and grow fast.

Second, look at the eyes: short-haired, bright-eyed pigs, healthy and lively, grow well, most of them are disease-free.

Look at the ears and nose: the nostrils should be large, commensurate with the mouth, the ears are big and thin, the ear roots are thick and hard, and the pigs with wide distance between the two ears can eat long.

Four look at the neck: neither thick nor thin, and have a certain length, sows can be longer, boars should be shorter, fattening pigs should not be too thick.

Look at the torso: the shoulders and backs should be wide. Miao pigs have high front shoulders, broad back and chest, flat and straight back, slightly drooping web, "yellow claw belly" in abdominal shape, exuberant breathing and blood, and rapid growth.

Six look at the tail: as the saying goes: "the tail is like a root nail, it grows one jin a day." Miao pig tail root thick, tail slightly red, tail skin thin, showing a "T-shaped", not only grow fast, but also docile.

Seven look at nipples: nipples are bright and thin, but not less than 6 pairs. It is best to cross and arrange evenly, sparse in front and dense in later. 7: 6 or 7: 8, and 8: 9 is the most ideal. This kind of pig has the characteristic of congenital cell division.

Eight look at the limbs: four legs are required to be strong, straight and thick, the thigh muscles are plump, the toenails are round and thick, the forks are large and obvious, the ratio of body length to height is moderate, the skeleton is large, and the growth is fast.

Nine look at the fur: the skin is thin, ruddy and clean, the intercostal hair is drooping, the coat is neat, and the hair is thin, smooth and bright. The Miao pig has a good physique and grows fast. If the rough-haired, pale and glossy pigs are mostly sick and stiff pigs

Ten look at the weight: the same litter of young pigs weaned, the greater the weight, the faster the general fattening, so it is appropriate to buy heavy pigs, that is, "grab the weight is not light", to facilitate short-term fattening.

National Day holiday look at feces: feces fall into strips or balls, smooth, loose for healthy young pigs, the normal color of urine is light yellow.

Twelve look at the spirit: the healthy Miao pig is full of spirit, stands naturally and walks smoothly. Lift up the hind legs of the pig, the pig does not bark or not loud, indicating that the temper is not grumpy, insensitive to the outside world, and can adapt to the new environment as soon as possible.

Second, how to improve the survival rate of pig seedlings?

1. Reduce the occurrence of poor vitality of newborn piglets as much as possible.

The poor vitality of newborn piglets may be caused by insufficient nutrition supply of sows during pregnancy or excessive toxins in feed, or it may also be caused by the long labor process of sows. Therefore, to provide sows with clean, hygienic and nutritious feed is the basic premise to ensure piglets. Weak babies are bound to have problems such as high morbidity, high mortality and slow growth. Focus on nursing care and feeding of weak babies whose birth weight is less than 0.8 kg or who are unstable and unable to breast-feed.

2. Ensure the heating of piglets and the cleanliness of the pigsty environment.

As soon as the piglets are born, dry the amniotic fluid of the piglets in time to prevent them from suffering from cold and diarrhea. It is best to keep the delivery room temperature at 32 ℃ and reduce the temperature difference on the home page. After giving birth, sows focus on cleaning and disinfecting their breasts and hindquarters to reduce the risk of piglets coming into contact with pathogenic microorganisms.

3. Make a good plan for epidemic prevention.

Pay attention to specific immunity and non-specific immunity, create group resistance as pig enterprises, all the benefits come from health. In the prevention of piglets diarrhea, we must ensure effective prevention of classical swine fever, foot-and-mouth disease, pseudorabies, mycoplasma, infectious pleuropneumonia and so on. Classical swine fever, foot-and-mouth disease, and pseudorabies are the foundation. Other vaccines such as blue ear disease, Haemophilus parasuis, transmissible gastroenteritis, epidemic diarrhea, Escherichia coli and red dysentery can be reasonably selected according to the situation of this field, and there is no need to force them. the effect is not very ideal.

The above is the introduction of pig seedlings. Farmers had better buy pigs directly at the pig farm, first understand the epidemic situation of this pig farm, the situation of suckling pig vaccine, check the relevant breeding records of pig seedlings, and so on, so that the possibility of buying low-quality pig seedlings can be minimized.
