| description | A 4×2 factorial feeding trial was designed to investigate the effect of
replacing soybean meal (SBM) with cottonseed meal (CSM) in
wheat/sorghum/SBM-based diets fed with or without microbial enzymes in diets on
the performance, visceral organ development and digestibility of nutrients of
broiler chickens. Four graded levels of CSM - none (0%), low (4%, 8%, and 12%),
medium (5%, 10%, and 15%), and high (6%, 12%, and 18%) of complete diets in
starter, grower and finisher, respectively were fed with or without 100 mg/kg of
xylanase and β-glucanase blend. Eight isocaloric and isonitrogenous diets
were formulated using least-cost method to meet the nutrient specifications of
Ross 308 male broilers. Each treatment was randomly assigned to 6 replicates (10
birds per replicate). There were CSM-enzyme interactions (p
< 0.05) on feed intake (FI) and weight gain (WG) in the starter phase. Enzyme
supplementation improved (p < 0.05) feed conversion ratio
(FCR) in the grower and finisher phases, and increased WG in growing and
finishing birds. CSM inclusion reduced (p < 0.05) the weight
of gizzard and proventriculus in starter chicks, while these organs were bigger
(p < 0.05) in the grower phase. The test ingredient
decreased (p < 0.05) small intestinal weight in starter and
grower birds. The CSM increased the absolute weight of thighs
(p < 0.05) while breast meat was increased
(p < 0.01) by enzyme addition. Starch digestibility was
improved (p < 0.01) by enzyme inclusion and decreased
(p < 0.01) by CSM. Enzyme supplementation improved
(p < 0.05) the ileal digestibility of gross energy and
protein. The results demonstrate that CSM can substitute up to 90% SBM in
broiler chicken diets without compromising performance, and the nutritive value
of CSM-containing diets can effectively be improved by enzyme
supplementation. |
