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
