Abstract: In order to use Shaeffer`s formula for the predication of body weight of slaughtering cattle, one hundred and four cattle, 52 of each male and female was used. Linear body measurements such as length from the point of shoulder to the point of pin bone and hearth girth (around the thoracic cavity just behind the elbow joint were taken with measuring tape just before the slaughter of the animals at the slaughter house of Hyderabad city. According to the formula W = G2 x L / 300. Where, "W" is the live body weight of animal in pounds, "G" is the Heart Girth (in inches) and "L" is the length from the point of shoulder to the point of pin bone (in inches). Finally the body weight was converted from pound to Kg. The mean body weight for Male cattle at the age of 2, 3, 4 and 5 years was 200.95kg (2.66, 298kg) (0.71, 300kg) (12.77, 454.04kg) (11.64 respectively. The mean body weight of Female cattle at the age of 2, 3, 4 and 5 years was 217.09kg (9.48, 266.25kg) (6.62, 313.71kg) (4.91 and 340.05kg (8.72 respectively). The present investigation showed a significant increase in the mean body weight of male and female cattle as the age of the animals advanced. The correlation of body weight with spleen size was also made which shows the increase trend in spleen size as the body weight increase.
