How do you select piglets? How can you improve the survival rate of piglets?

Last year, affected by African swine fever, pork prices rose steadily. This year many farmers are very optimistic about the pork market, and because of this the number of farmers raising pigs has also increased. For farmers who want to raise pigs, the most important thing is selecting piglets. Generally speaking, a normal ordinary pig takes about 6 months from birth to slaughter, with a body weight of about 120-130 kg. So how do you select piglets? How can you improve the survival rate of piglets? Now let's take a look together.

1. How do you select piglets?

First, look at the mouth shape: a mouth that is short and rounded, large and neat, with a deep mouth slit, especially the lower jaw should be thin. Piglets whose lower jaw and upper jaw are level and neat eat a lot, are not picky, are easy to raise, and grow fast.

Second, look at the eyes: pigs with short eyelashes and bright, spirited eyes are healthy and lively, grow well, and the vast majority are free of disease.

Third, look at the ears and nose: the nostrils should be large and match the mouth; pigs with large and thin ears, thick and hard ear bases, and a wide distance between the two ears can eat and will grow.

Fourth, look at the neck: neither thick nor thin, and of a certain length; sows can be a bit longer, boars appropriately shorter, and the neck of fattening pigs should not be too thick.

Fifth, look at the torso: the shoulders and back should be broad. Piglets with a high front shoulder, broad and well-developed back and chest, a flat, straight and long back, and a broad, flat belly that sags slightly; a belly shaped like a "yellow melon belly" is best. Respiration and blood circulation are correspondingly vigorous, and growth is also rapid.

Sixth, look at the tail: as the saying goes, "If the tail is like a nail, it gains one jin a day." Piglets with a thick tail base, a reddish tail tip, and thin tail skin, forming a "T shape," not only grow fast but also have a gentle temperament.

Seventh, look at the teats: the teats should be distinct and spaced apart, but no fewer than 6 pairs. It is best if they are arranged evenly in a crisscross pattern, sparse in front and dense at the back. 7+6 opposite or 7+8 opposite, with 8+9 opposite being the most ideal; this kind of pig has the innate characteristic of rapid cell division.

Eighth, look at the limbs: the four legs are required to be strong, round, straight, thick and long, with full thigh muscles, round and thick hooves, and large and obvious hoof clefts; a moderate ratio of body length to body height, a large frame, and fast growth.

Ninth, look at the skin and hair: piglets with thin, rosy and clean skin, hair between the ribs hanging downward, neat coat, and sparse, smooth, glossy hair have a good physique and grow fast. If the skin is coarse and the hair is messy, and the pig is pale with no luster, it is mostly a sick pig or a stunted pig.

Tenth, look at body weight: when piglets from the same litter are weaned, the heavier ones generally gain weight faster during fattening, so it is advisable to select heavier piglets, that is, "grab the heavy, not the light," to facilitate short-term fattening.

Eleventh, look at the manure: healthy piglets pass manure that falls to the ground in strips or clumps, smooth and loose; the normal color of urine is pale yellow.

Twelfth, look at the spirit: healthy piglets are full of energy, stand naturally, and walk steadily. If you lift a pig's hind leg and the pig does not squeal or squeals only softly, it shows that its temper is not irritable, it is not sensitive to external stimuli, and it can adapt to a new environment as quickly as possible.

2. How can you improve the survival rate of piglets?

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

Poor vitality in newborn piglets may be caused by insufficient nutritional supply during the sow's pregnancy, or by excessive toxins in the feed, and may also be caused by a prolonged farrowing process in the sow. Therefore, providing sows with clean, hygienic and nutritionally complete feed is the basic prerequisite for ensuring piglet health. Weak piglets will inevitably have problems such as a high incidence of disease, a high mortality rate, and slow growth. Pick out weak piglets with a birth weight below 0.8 kg or those that cannot stand steadily and do not know how to suckle, and give them focused care and feeding.

2. Ensure piglets stay warm and keep the pig house environment clean.

As soon as piglets are born, promptly dry the amniotic fluid off their bodies to prevent them from catching cold and having diarrhea. The farrowing house temperature is best kept at 32°C, and the temperature difference at the front of the house should be reduced. After the sow gives birth, focus on cleaning and disinfecting the udder and hindquarters to reduce the risk of piglets coming into contact with pathogenic microorganisms.

3. Do a good job of planned epidemic prevention.

Pay attention to specific immunity and non-specific immunity, and build herd resistance. As a pig-raising enterprise, all benefits come from health. In preventing piglet diarrhea, you must ensure effective prevention of swine fever, foot-and-mouth disease, pseudorabies, mycoplasma, infectious pleuropneumonia, and so on. Swine fever, foot-and-mouth disease, and pseudorabies are the foundation of the foundation. Other vaccines such as those for blue ear disease, Haemophilus parasuis, transmissible gastroenteritis, epidemic diarrhea, Escherichia coli, red dysentery, and so on can simply be selected reasonably according to the situation on your own farm; there is no need to insist on them, and the results are not very ideal either.

The above is an introduction to piglets. When selecting pigs, farmers had best buy directly at the pig farm, first understand the disease situation at that pig farm, the vaccination situation for suckling piglets, and check the breeding records related to the piglets, and so on. In this way, the possibility of buying inferior piglets can be reduced to the minimum.
