Effect of inclusion of different levels of liquid corn gluten on performance, carcass characteristics and blood parameters of broiler chickens

Experiment was conducted to evaluate the effect of inclusion of liquid corn gluten to broiler diet on growth performance, carcass characteristics and blood parameters. In a randomly complete design two hundreds (200) day old broiler chicks (Ross 308) were divided into 20 groups, ten chicks per group, and five experimental diets were formulated and each diet was given to four replicates from 1-42 days of age. Diets were fed to the chickens from 1-14 (starter), 15-28 (grower) and 29-42 (finisher) days of age. Liquid corn gluten was used at levels of Zero (control), 2.5, 5.0, 7.5 and 10 % in iso-caloric and iso-nitrogenous diets. Chicks had free access to feed and water and exposed to continuous light (22 h) during experimental period. Experiment was performed in 1*1 floor pens. Feed intake, body weight gain, were recorded and feed conversion ratio was calculated. The results indicated that liquid corn gluten at level of 5% had positive effect on body weight gain and feed conversion ratio, but reduced feed intake during starting, growing and finishing periods. Body weight gain was increased (P<0.05) and feed conversion ratio was reduced (P<0.05) due to added liquid corn gluten. Oven ready carcass, thigh and breast were significantly (P<0.05) affected due to liquid corn gluten and were increased. Added liquid corn gluten had significant (P<0.05) effect on blood cholesterol, glucose and were reduced due to 5% inclusion level. Overall, results showed that liquid corn gluten can be used in broiler diet without any negative effects on performance, carcass characteristics and some blood parameters
