Procedure.
A] Direct method.Animal is weighed directly on weighing machines or platform scales.B] Alternate method / indirect method. In this method, weight of an animal is indirectly calculated from body measurements
C] Schaeffer’s formula:- It is widely accepted for estimating body weight of an adult cattle.

Length × Girth 2Live body weight (in pounds) = 300
The formulae used in indirect method for estimating body weight are as below.
Were,Length = Distance between point of shoulder to pin bone in inches.Girth = Entire circumference of the body behind the point of elbowing inches

Length × GirthLive body weight = ( in pounds) Y Where.Y = 9 if the girth is less than 1.62 meters.Y = 8.5 if the girth is less than 1.62-2.0 meters.Y = 8.0 if the girth is less than 2.0 meters.
Agarwals Formula:- It is modified Schaeffer’s formula for Indian cattle.
