Abstract
This study was conducted for 56 days using 375 one-day-old Marshal broiler chicks (34.20 g ± 0.06) to evaluate the dietary inclusion of untreated soybean hulls (SH) and Zymomonas mobilis treated soybean hulls (SHZ) on growth response, apparent nutrient digestibility, ileal digesta viscosity and economy of feed conversion ratio. The broiler chicks were randomly allotted to five dietary treatments with 75 birds per treatment and were replicated 5 times with 15 birds each. The SH and SHZ replaced wheat offal at 0, 50 and 100% levels both at the starter and finisher phases. The experimental design was completely randomized. At the starting phase, the broiler chickens fed 100% SHZ had the lowest (P < 0.05) value of feed conversion ratio while those fed 100% SH had significantly (P < 0.05) highest protein efficiency ratio (PER). At the finishing phase, the birds fed 50% SH and 100% SH had statistically similar (P > 0.05) and the highest (P < 0.05) values of PER while birds fed 50% SHZ had the lowest value. T he crude fibre digestibility highest value was observed at 100% SH while the lowest value recorded in the control diet was similar (P > 0.05) to the values obtained in 50% SH and 50% SHZ at the finishing phase. Birds fed 50% SHZ had increased (P < 0.05) ileal digesta viscosity at 100rpm. The broiler chickens fed SH and SHZ had the highest (P < 0.05) values of gross profit, rate of return on investment, economic efficiency and relative cost benefit. Therefore, it was concluded that 100% SHZ could promote the growth response and economic efficiency of broiler chickens.
