Pig weight range, the formula for calculating pig weight

Hello, you want to know what kind of pigs.

Piglets: In the farrowing room, from birth to slaughter, generally about 5 kg to 75 kg.

Nursery: after weaning, 75 kg to 170 kg.

Fattening: The small ones are about 140 kilograms, and the sows and boars are about 300 kilograms or more.

As far as I know, the smallest is the Parma pig, about a few taels to a few kilograms, and the domestic pig I see in my hometown is more than 500 kilograms

Summary. The weight of a pig is measured by a factor of: body weight (kg) = chest circumference (cm) body length (cm).

Hello dear, happy to answer for you. Pig's weight estimation method weight (kg) = body length (cm) Chest circumference (cm) 142 or Chang Pao 156 or Han Xun cavity 162 Talk about shirts: fat pigs are divided by 142, thin pigs are divided by 162, and pigs that are not fat or thin are divided by 156.

The weight of a pig is measured by a factor of: body weight (kg) = chest circumference (cm) body length (cm).

Body weight (kg).

Chest circumference (cm) Body length (cm) factor.

Note: 1. The coefficient of good nutritional status of pigs is 142; The coefficient for medium nutritional status is 156; The coefficient of malnutrition is 162. This method can only measure the approximate weight of the pig, not the exact weight, and is for reference only.

2. (1) Body length: From the middle of the midpoint line of the two ear roots, use the tape measure to measure along the dorsal ridge to the first natural ring pattern of the tail root, and the standing posture is normal (the limbs are upright, and the lower line of the collar is the same as the lower line of the chest), fix the end point of the tape measure on the occipital joint with the left hand, pull the tape measure with the right hand and fix it at any point of the dorsal midline, and then replace the position of the right hand with the left hand, and then pull the tape measure with the right hand until the root of the tail, that is, measure the body length.

2) Chest circumference: Measure the vertical circumference of the chest with a tape measure at the back edge of the shoulder blade, and the tightness should be natural to the fur with a tape measure.

Weight measurement method: weight estimation is to calculate the weight with the above measurement value formula when the pig is not weighed under the conditions.

Answer: Pig weight (kg) = chest circumference (cm) Body length (cm) coefficient where chest circumference is the length of the posterior corner of the shoulder blade around the chest cage; Body length is the length from the midpoint of the line connecting the ears along the dorsal midline to the base of the tail. How to measure the chest circumference: Measure the vertical circumference of the chest with a tape measure at the back edge of the shoulder blade, and the tightness should be so that the tape measure naturally fits the fur.

Body length measurement method: from the middle of the midpoint line of the two ear roots, use a tape measure to measure along the dorsal ridge to the first natural wheel pattern of the tail root, the standing posture is normal (the limbs are upright, the lower collar line is the same as the lower line of the chest), fix the end point of the tape measure on the occipital joint with the left hand, pull the tape measure with the right hand and fix it at any point of the dorsal midline, and then replace the position of the right hand with the left hand, and then pull the tape measure with the right hand until the root of the tail, that is, measure the body length.

Hope it helps.

Typically, pigs weigh 300-500kg. However, the weight of different breeds of pigs is also different, for example, the weight of Landrace pigs is 400-500kg, the weight of Bozhong pigs is about 300-450kg, and the weight of horse pigs is about 150-250kg, so the specific weight of pigs needs to be determined according to the actual situation.

Under normal circumstances, when the fattening pig weighs 90-100kg, it can be slaughtered. Because if you continue to feed, the feed utilization rate of fattening pigs will be relatively low, and waste feed will be time-consuming.

Pig breeding should pay attention to the following points:

1) Keep the pig house clean.

Summer is the peak season for mosquitoes and flies, which not only causes a poor production environment for pig farms, but more importantly, brings difficulties to the prevention of diseases in pig farms. Therefore, it is necessary to regularly disinfect the internal and external environment of the pig house, including the barn, the site and utensils, instruments, as well as the drainage channel, air and the whole body surface of the sow, etc., and should also pay attention to the disinfection of some sanitary dead corners.

2) Scientific feeding, reasonable mix of feed, to ensure that the feed is fresh.

In summer, we should feed more green feed rich in vitamins and minerals and cool feed such as fruit peel such as watermelon skin; Seasoning agents such as saltiness, umami or aroma are appropriately added to the mixture to improve the palatability of the feed, increase the feed intake of pigs, and prohibit feeding moldy feed.

3) Plant greening to improve the microclimate of the site.

Reduce the proportion of concrete floor in the farm to reduce the ground temperature. Increasing the ground green area of the pig farm can reduce the ambient temperature of the pig house 3 4 and reduce the heat radiation by 80%. However, tall trees should not be varied, which affects ventilation and can also attract wild birds, which is not conducive to epidemic prevention.

4) In midsummer, do not pour cold water on the pig to cool the pig.

If the weather is hot, you can dig a pit in the corner of the pigsty, and put enough cold water in the pit for the pigs to bathe.

The minimum is about ten pounds ......The largest seems to be 800 ......There are generally more than three hundred.

Chinese alone eat 700 million pigs a year, and the world always maintains 1 billion pigs, all of which are domestic pigs, that is, 90kg, although the pig breeding data that can be referred to is vast, but looking at the opinions of scholars and experts, there is almost a common conclusion: fat pigs raised to 90 kg slaughter is the best economic weight, that is, the most cost-effective. I don't bother to talk about the details, the average pig weighs this question is undoubtedly 90kg.

But if it is said that ordinary pigs, domestic pigs and wild boars are close to 1 ton, which is larger than adult brown bears.

The average adult pig is more than 200 catties.

Commercial pigs are generally sold at 90kg.

There is a big fat pig in Ningxiang, Hunan, which is long and high, and weighs 850 kilograms.

There are 3 formulas for estimating pig weight, which are first-class fat pig weight (kg) = (body length and chest circumference behind the shoulder blades) 142;Medium fat pig weight (kg) = (body length posterior shoulder blade chest circumference) 156;Inferior pig weight (kg) = (body length posterior scapular chest circumference) 162.

1. Weight measurement formula: weight (kg) = chest circumference (cm) body length (cm) coefficient, the coefficient of good nutritional status of pigs is 142, the coefficient of medium nutritional status is 156, and the coefficient of poor nutritional status is 162.

When the standing posture is normal (limbs upright, the lower collar line is the same as the lower line of the chest), fix the end point of the tape measure on the occipital atlantomotor joint with the left hand, pull the tape measure with the right hand and fix it at any point of the dorsal midline, then replace the position of the right hand with the left hand, and pull the tape measure with the right hand until the base of the tail, that is, measure the body length.

Measure the vertical circumference of the chest at the posterior edge of the shoulder blade with a tape measure, and the tightness should be such that the tape measure naturally fits the fur.

The standard weight of pigs for slaughter is generally about 200 catties. The time for pigs to be slaughtered is generally about half a year, and there are also some pigs that are raised, and the time for slaughter will be longer, about 220 days. As long as the pig's weight is reached, it can be slaughtered.

Question pig breast 167The pig is 170 boxes long.

Answer: Pig weight (kg) = chest circumference (cm) Body length (cm) 142 (fat) or 156 (medium) or 162 (lean) Description: , chest circumference is the length of the posterior corner of the shoulder blade around the ribcage; Body length is the length from the midpoint of the line connecting the ears along the dorsal midline to the base of the tail.
