Weight is an important index in swine meat industry. Indirect method of weight measurement involves usage of body measurements. Heart girth is known to be better correlated with body weight in pigs. A study was carried out to determine the relationship between different girths like the heart girth (measured just behind the forelimbs), middle girth (measured around mid-region of the body) and tail girth (measured just in front of the hind limbs) and live weight in Landly pigs (Landrace* Desi). Data was collected for body length, girths, and live weight in 39 pigs, both male and female and 9–10 months of age, reared in the IVRI Swine farm. Multiple linear regression method was used for analysis under GMP9. The results showed high positive correlations of weight with middle girth. Area calculated using middle girth and heart girth had the best fit and the lowest error. This can be applicable to pigs reared under field conditions.
HIGHLIGHTS
Usage of different girths for prediction of body weights in pigs.
Middle girth alone and in combination with heart girth provides best estimation of body weight.
