چکیده انگلیسی
The aim of the present study was to investigate the effects of different levels of palygorskite on the pellet quality, growth performance and nutrient utilization in broilers. Three hundred one-day-old Arbor Acres broilers were randomly divided into five treatment groups with six replicates of ten broilers each for a 42-day feeding trial. The birds were fed diets supplemented with 0, 5, 10, 15 and 20Â g/kg palygorskite, respectively. The results showed that the hardness and durability index of pellets were improved (linear and quadratic, PÂ <Â 0.001) with the increasing level of palygorskite inclusion. The palygorskite supplementation improved average daily gain (ADG) and average daily feed intake (ADFI) of broilers (linear and quadratic, PÂ <Â 0.001). The broilers fed the diet supplemented with 10Â g/kg palygorskite had the highest ADG among groups. Compared with the control group, neither 5Â g/kg nor 10Â g/kg palygorskite inclusion affected feed per unit gain (F/G) of broilers. However, the F/G in grower period increased 1.6% with diet 15Â g/kg (1.83 vs 1.80) and 3.3% with diet 20Â g/kg (1.86 vs 1.80). The results indicated that palygorskite inclusion could enhance the pellet hardness and durability index, and improve the growth performance of broilers. In additional, the optimal level of supplemented palygorskite in the pellet diets of broilers was 10Â g/kg.
