چکیده

Four hundred fifty day old unsexed broiler chicks were used in a 35-day trial at Chittagong veterinary and animal sciences university farm to find out the effect of using crude soybean oil sediment (CSOS) as a substitute for refined soybean oil (RSO) in broiler diet. The experiment was carried out following completely randomized design. The chicks were randomly distributed in three treatment groups having three replications per treatment. Each replication had 50 birds. The house was divided by wire net into nine compartments to maintain desired replication. Birds were fed three types of diet i.e. diet without CSOS and RSO (T₀), diet containing RSO (T₁) and diet containing CSOS (T₂). All birds had free access to ad libitum feeding. Results indicated that no variations (P<0.05) were observed in weight gain of birds for the 1^st and 2^nd week except at 3^rd, 4^th and 5^th week irrespective of dietary treatments. At 5^th week, average weight gain was maximum (73.7±2.1 g/d) in birds fed diet containing RSO (T₁) and minimum (65.6±2.7 g/d) in birds fed diet without CSOS and RSO (T₀). Similar to weight gain, average feed intake differed (P<0.01) and the mean values were 55.3 ± 2.1, 50.5 ± 1.9 and 53.4 ± 2.0 g at 2^nd week, 92.5 ± 3.1, 83.4 ± 2.3 and 84.4 ± 2.2 g at 3^rd week and 116.4 ± 2.3, 114.5 ± 1.9 and 120.4 ± 2.7 g at the 4^th week for T₀, T₁ and T₂ treatment groups, respectively. Feed conversion ratio (FCR) differed (P<0.05) only at 5^th week and the mean values were 2.03 ± 0.12, 1.80 ± 0.11 and 1.90 ± 0.09 for T₀, T₁ and T₂ treatment groups, respectively. Best feed FCR (1.80±0.11) was found in birds fed diet containing RSO (T₁) and comparatively poor FCR (2.03±0.12) was found in birds fed diet without CSOS and RSO (T₀). It could therefore be inferred that, RSO may be replaced by CSOS in broiler diet.
