What is the formula for calculating the weight of pig hair?

The formula is: gross weight (weight kg) = chest circumference (CM)× body length (CM)/ coefficient. When determining the pig coefficient, it needs to be determined according to their nutritional status. If the nutritional status of pigs is good, the coefficient can be 142, if the nutritional status of pigs is moderate, the coefficient can be 156, and if pigs are malnourished, the coefficient can be 162.

According to the nutritional status of pigs:

1. If the pig's fat is good, the estimation formula is: weight (kg)=[ body length (cm) × scapular chest circumference (cm)] ÷ 142.

2. If the pig is moderately obese, the estimation formula is: weight (kg)=[ body length (cm) × scapular back bust (cm)] ÷ 156.

3. If the pig's condition is poor, the estimation formula is: weight (kg)=[ body length (cm) × scapular chest circumference (cm)] ÷ 162.

However, in actual production, this method of estimating weight by formula has a big error, and the obtained data can not be used to optimize formula and adjust feeding methods, and pig dealers don't approve it at all when selling pigs, so few pig farmers use it. Overall, the application value is very low.

Calculate the gross weight of pigs: Gross weight refers to the pure weight of pigs standing on the scale.
