How to estimate the weight and net meat weight of yellow cattle?

The method for estimating the weight and net meat weight of yellow cattle is as follows:

Formula for calculating the weight of livestock:

1000 Jin of live cattle is about 350 Jin of pure beef.

1, the weight of excellent beef cattle = the square of chest circumference times the straight body length times 100.

2. Weight of fat yellow cattle (kg)= bust (cm)× bust (cm)× body oblique length (cm) ÷10800 ×1.1385.

3. Weight (kg) of medium fat yellow cattle = bust (m) × bust (m )× body oblique length (m) ×90× 1. 1385.

4. Weight of lean cattle (kg)= bust square meter × length meter *80+ 100.

5. The weight of cattle in the acquisition plan (kg)= chest square meter × body length meter *80.

Second, the estimation method of pig weight (weight: kg)

Weight of the first-grade pig = body length (cm) × back bust of scapula (cm)/ 142

The weight of a moderately obese pig = body length (cm) × scapular chest circumference (cm)/ 156.

Weight of inferior pig = body length (cm) × back bust of scapula (cm)/162

Note: Body length is the length (cm) from the midpoint of the connecting line between the two ear roots, along the back to the tail root; The chest circumference behind the scapula is the length (cm) of the chest measured with a tape measure along the back corner of the scapula.

Third, the estimation method of sheep's weight

Weight of sheep (kg) = bust (cm) 2× body length (cm) /300.

Note: Body length is the length from the midpoint of the line connecting the two ears to the tail root.
