Evaluation of two herbal spices as feed additives for finisher broilers
Onu P.N.
The aim of this study was to evaluate the effect of two herbal spices as feed
additives for finisher broilers. 120 5-week old birds were randomly assigned
to four treatments in a completely randomized design. Each group was further
subdivided into three replicates of 10 birds per replicate. Four experimental
diets were formulated such that diet I (T1) which served as the control
contained neither ginger nor garlic. Diets 2 (T2) and 3 (T3) contained 0.25%
garlic and ginger respectively. Diet 4 (T4) contained a combination of 0.25%
of garlic and ginger. Response parameters evaluated include weight gain, feed
intake, feed conversion ratio, blood parameters and carcass characteristics.
The experiment lasted for 35 days. Results showed that birds fed supplemented
diets had significantly (P<0.05) higher body weight gain and superior feed
conversion ratio than birds fed the control diet. There was no significant
(P>0.05) difference in the feed consumption of the birds among the
treatments. The hematological indices, serum biochemistry and carcass
characteristics of the birds among the treatment were not significantly
(P>0.05) influenced by the dietary treatments. The results of this study
suggest that ginger and garlic can be included in broiler finisher diets
without adversely affecting the performance of the birds.
