Nine Salmonella isolates (11.25%) from 80 spleen samples of pigs collected from slaughter house detected by conventional culturing when subjected to Salmonella-specific gene (invA) yielded product a 284-bp DNA fragment.

Atotal of twenty four LargeWhite Yorkshireweaners nearly of same body weight were selected for the present study.The prediction equations were constructed to estimate the body weight of pigs indirectly from different body measurements of 24 pigs. The body weight was highly correlated (PO.OI)with body length, heart girth and height at withers. Accuracy for the measurement of body weight with prediction equation using one or two independent variables shifting from heart girth to height at withers with increase in body weight. Coefficient of multiple determination (R2)increases gradually as the number of independent variables increased in the prediction equation and the best prediction equation was observed when all the 3 body measurements were included in the equation. orrelationcoefficientof body weightwith body measurementswere also foundto be highly correlated.
