Growth performance, cut parts and internal organ characteristics of broiler chickens fed raw Senna obtusifora seed meal supplemented with enzymes

Abstract

Growth, cut parts and internal organ characteristics of broiler chickens fed raw Senna obtusifolia seed meal (SOSM) supplemented with enzymes was evaluated. 96 day-old unsexed Arbor acre chicks were randomly assigned to 4 dietary treatments of 24 birds, replicated thrice with 8 birds per replicate in a Completely Randomized Design. The dietary treatments 1,2, 3 and 4 contained 0%, 5%, 7.5% and 10% raw SOSM, with each diet supplemented with 20g/100 kg Maxigrain® enzymes, except T1 diet (control) at starter and finisher phases, which lasted 56 days. At the end of the experiments, growth parameters were evaluated. Also one bird per replicate whose weight was close to the mean, was selected for evaluation of carcass and internal organs characteristics and data were expressed as percentage of dressed weight. All data were subjected to one-way analysis of variance. The results showed that broiler chickens fed raw SOSM supplemented with enzymes did not significantly (P>0.05) influenced all the growth parameters. The final live weights ranged from 1833.33 g to 2363.33 g. Also, carcass characteristics of broiler chickens showed no significant differences (P>0.05) in all the parameters except the wings. However, the final live weight before slaughter numerically decreased from 2034.33 g for birds fed T1 diet to 1942.33 g for birds fed T4 diet. There was significant difference (P<0.05) in the mean values of broiler chicken wings fed raw SOSM supplemented with enzymes. Birds fed T3 diet recorded the highest value of 10.84, which was significantly different from birds fed T2 diet (8.81). There was numerical decrease in mean weights of liver and kidney across treatments with increasing dietary of raw SOSM, supplemented with enzyme. In conclusion, raw SOSM could be fed up to 10% inclusion level, with enzyme supplementation, to broiler chickens without any adverse effects on their growth, cut parts and internal organs parameters.
