Use of corn steep liquor in wet-feeding of broiler chickens

The effects of wet-feeding of five levels of corn steep liquor (CSL) on broilers performance and relative internal organ weights were examined. Three hundreds 1-d old broilers (Ross 308) were randomly allocated to one of the six dietary treatments in a completely randomized design with 5 replications of 10 chicks per pen. The dietary treatments were: 1. Dry-fed control, no add water nor CSL in feed, 2. Wet-fed control, add water in feed, 3. Wet-fed, 10% CSL in feed, 4. Wet-fed, 20% CSL in feed, 5. Wet-fed, 30% CSL in feed, and 6. Wet-fed, 40% CSL in feed. The body weight gain, feed intake and feed conversion ratio were significantly affected by dietary levels of CSL inclusion, in 1-42 d growing period (P< 0.05). The response to increasing dietary levels of CSL was in linear and quadratic manners (P< 0.05). Using of CSL levels higher than 10 % declined the growth performance. Increase in dietary CSL levels beyond 10 % caused a significant decrease in relative weights of liver, bursa Fabricius, and gizzard (P<0.05). The results of present study suggest 10 % CSL as an optimum level of CSL dietary supplementation in wet feeding of broilers.
