How to choose good healthy, fast growing piglets

1. Choose piglets with the same litter and large body, and it is best to choose piglets from the same litter when buying piglets, because the same litter of Xinhuixun piglets does not bite the frame, and can get along more harmoniously, and it is easy to raise and grow fast. Choose the big ones when buying, because the smallest in a litter is generally weak.

2. Look at the mental state, healthy piglets have big eyes, lively and active, they will have a sense of fear when they see people, they will look around vigilantly, and they can stand up quickly, stand naturally, and walk lightly.

3. Observe the feeding and drinking conditions, the appetite of healthy piglets is proportional to the daily weight gain, and when feeding the feed, there will be a sense of hunger, screaming, scrambling to grab food, slipping this to eat when the mouth stretches into the bottom of the food grains, swallowing a large mouthful, and will make a rhythmic and crisp rattling sound, and will drink water regularly after feeding.

4. Look at the tail posture when standing, when the healthy pig stands, the tail tip curls and swings rhythmically, while the sick pig stands, the tail droops and does not move.

5. Looking at the body, the healthy piglets with normal development of each part of the body, the body is stout and the body length is moderate.

Answer: The following points should be paid attention to when selecting piglets: Good eyes.

Healthy pigs are in good spirits, have bright eyes, do not stick to eye feces, and are afraid of people; The sick pig is in a bad spirit, with an improper posture, closed eyes, and is too lazy to move. Be high-pitched. Grab the pig's ear, and the healthy pig makes a loud scream; Sick pigs have hoarse and low voices.

The hair should be shiny. Healthy and disease-free piglets grow "watery", with bright fur and no bleeding spots on their bodies; Sick pigs are "fried", the hair is messy, and there are often bleeding spots or acne and sores. Keep your mouth shut.

Such pigs generally do not arch food, do not arch grooves, do not arch circles, and do not waste feed when eating. Legs should be long. Such a pig juvenile skeleton can be naturally opened, which is convenient for short-term fattening, and is large.

Shoulders should be broad. Such pigs tend to eat more and grow faster. The tail is whip-shaped.

That is, the roots are thick and thin, and they often swing; The tail of the sick pig droops and does not wobble.

The selection method is: let the piglets walk around on the ground at will, observe carefully, and do seven looks.

1.Look at the state of mind. Healthy piglets are lively and active, with bright eyes and crisp voices. The coat is smooth and shiny, and the tail wags non-stop. Reacts quickly to sounds.

2.Look at the characteristics of the breed and the overall development. Binary crossbreeding, ternary crossbreeding, or multi-cross piglets have certain characteristics of hybrid breeds, so that the selection criteria are consistent and prevent mixing with unhealthy and eliminated purebred piglets.

3.Look at the physical condition. Healthy piglets are in good condition, with normal development, shiny coat and moist nose. Do not choose: poor body condition, thin piglets do not choose; Those whose weight is significantly smaller than that of the large group are not selected.

4.Look at the abdominal circumference. Healthy piglets with full abdominal circumference but not bloated. Sick pigs are often hung or have a full belly, and are not selected.

5.Look at the limbs. Healthy piglets walk with their limbs well-matched. Piglets with lameness and deformity are not selected; Piglets with leg shapes inside and outside are not selected; The thickness of the legs is inconsistent, the joints are swollen, and the hoof system is not good.

6.Look at the feces. Healthy piglets with normal feces color and traits. If the stool is thin or dry and the color is abnormal, it is considered to be in poor health and should not be selected.

7.Look at the evenness of development. Try to make a batch of purchased piglets, so that the age, weight is similar, the development is uniform and neat, and the piglets that are too large or too small are not selected. Make sure that the piglets you buy are uniformly sized, healthy and of high quality.

1. Look at your eyes.

Healthy piglets have bright eyes and are scared when they see people. The sick pig is more sluggish, his eyes are closed, and he is too lazy to move when he sees people. Second, the legs should be long.

Healthy piglets have a natural skeleton that is open, develops quickly in the short term, and is large in size.

Third, the hair should be bright.

Healthy and disease-free piglets have shiny fur and no bleeding spots on their bodies. And the sick pig hair is somewhat unkempt and dull, ** has some bleeding spots.

Tips and precautions for selecting new piglets.

Fourth, the shoulders should be broad.

Piglets with wide shoulders eat a lot and therefore grow faster.

Fifth, the tail is whip-shaped.

Pigs have thin tails and often swing around, while diseased pigs have droopy tails and don't move very often.

6. Keep your mouth short.

Piglets with short mouths tend not to arch food, arch grooves, arch circles, and do not spoil feed when eating.

Tips and precautions for selecting new piglets.

7. Be high-pitched.

Pigs that scream loudly after grabbing the piglet's ears are healthy pigs. If the pig is hoarse and low, it is a sick pig.

The advantages and disadvantages of piglets can be reflected in appearance, production performance, growth and development. Therefore, when buying piglets, they should be carefully selected in terms of their appearance (head, neck, torso, buttocks and limbs). First, the basic requirements when selecting piglets, first of all, to understand the local disease flow.

It is often said that "the process of introducing seeds is also the process of introducing diseases". If you don't understand the local epidemic situation, blindly introducing piglets, the harm of bringing in diseases will far outweigh the benefits brought by piglets. It is necessary to understand the condition in advance and take precautions; Select from a healthy herd to minimize the risk of introduced diseases.

Second, the breed of pigs is different, the growth rate, lean meat rate has a large degree of difference, and the requirements for feeding conditions are also different. Native pigs grow slowly, have a long growth period, low lean meat rate, are easy to feed, and have low requirements for feed. Crossbred pigs grow fast, have a high lean meat rate, and have higher requirements for feed, but are higher and can achieve higher profits. 3. Body shape and appearance 1. Spirit:

Healthy piglets are energetic and active, with a smooth, neat coat, standing naturally and a steady gait. 2. Eyes: The eyes are bright and bright, the conjunctiva of the eye is pink, there is no secretion, and the vast majority of pigs who have a sense of fear are disease-free.

3. Ears and nose: healthy piglets have moist noses, pink mouths without swelling, no viscous secretions, and even breathing, large nostrils; The ears are large and thin, the roots of the ears are thick and hard, and the distance between the ears is wide. 4. Torso:

The shoulders should be broad. The piglets have high front shoulders, broad back chest and good development, flat and straight back, large but not sagging, that is, people often say "cucumber belly" is better, so that the pig's breathing and blood are correspondingly vigorous, and the growth is also rapid. 5. Limbs:

Piglets are required to have strong legs, round and straight, thick and long, full thigh muscles, round and thick hoof nails, large and obvious hoof forks, moderate ratio of body length and body height, large skeleton and fast growth. 6. Manure: Healthy pig manure is relatively soft and moist, in the shape of a cone.

Urine is normally pale yellow in color. If it is found that the pig with posterior rump contamination may have intestinal diseases, it is better to give up the selection of the whole litter of piglets, and try to introduce less disease into the farm, so as not to transmit the disease to healthy piglets and bring unnecessary losses. Fourth, feeding characteristics and epidemic prevention When buying piglets, first learn from the owner whether the piglets eat powder or thinner, raw or cooked, concentrate or green coarse feed, feed several times a day to determine the feeding method.

In addition, it is necessary to ask the owner about the epidemic prevention situation of the piglets, so that the corresponding epidemic prevention procedures can be carried out in time after the purchase.

Piglet selection is mainly to choose healthy, good mental state, do not go to the market to buy casually, it is best to choose pig farms.

You should note that in the same litter, the larger pigs tend to be healthier; Or, observing its appearance, the physique is more symmetrical, ** white and red, the pork hair is shiny, more lively and active, and often healthier; The body is uneven, thin, unsightly, yellowish and black, pig's hair is not smooth, messy, etc., it is definitely not so good. After the piglets are born, they are gradually fed soybean flour (tofu residue, sake lees) and other feeds, which are particularly beautiful and healthy, and are loved by everyone.

Selecting good piglets is the basis and premise of raising good fattening pigs. If you want to select piglets that grow fast, save feed, have less disease and high efficiency, you must refer to the following aspects:

A look: healthy piglets have great eyes, flexible movements, light and healthy walking, smooth fur, white pig skin and red flesh, no curly hair, loose hair, smegma, eye feces, odor, hindquarters without fecal pollution, gluttony, so strong, often raise the tail to fight for food. If the piglets are sluggish, lame, curly, messy, have eye droppings, and fecal contamination in the hindquarters, they are mostly sick pigs or unhealthy piglets, and should not be purchased.

Second question: ask whether the breed of piglets has been quarantined by the local veterinary department and ask for a quarantine certificate, whether there is an epidemic of some infectious disease in the local area, and whether it has been vaccinated with swine fever, swine erysipelas, swine lung disease, swine streptococcus and swine paratyphoid fever.

Three choices: select littermates with large weight, do not choose small weight; Select piglets with long waists, wide front chest, short mouth, plump back buttocks, thick and powerful limbs, reasonable ratio of body length and body width, and a sense of stretching, and do not choose "big in the middle, two small" short round piglets; Select hybrid piglets whose father is a foreign breed, preferably a three-breed hybrid piglet, and do not buy purebred piglets of local breeds; Choose piglets with ear defects (those who have been vaccinated) and do not choose piglets without ear defects.
