ADDITION OF PROPIONIC ACID ON NUTRIENT DIGESTIBILITY AND ITS EFFECT ON PRODUCTION AND CARCASS QUALITY OF BROILER

This study was aimed to determine protein and crude fiber digestibility by adding propionic acid in rations its effect on production carcass quality broiler chicken. research carried out using 180-day old chicks (DOC) chicken with Cobb strain. method used a completely randomized design (CRD) consisting of three treatments six replications for every treatment. The treatment this consisted of: T0 = ration without acid; T1 addition 0.5% the ration; T2 0.75% ration. Parameters observed included protein, digestibility, feed consumption, body weight gain, conversion, live weight, percentage, percentage abdominal fat chickens. results showed that had significant (P<0.05) fiber's Significantly increased consumption up 2.29%; gain 7.49 %, decreased conversion 4.86%; 12.69%; 4.12% 33% concludes at dose could be increase rations, can improve performance
