Efficacy of Aniseed Extract as Immune Stimulant and Growth Promoter in Broiler Chicks
Present research was undertaken to investigate the effect of different level of 6% concentrated (w/v) aniseed extract in broiler chicks at NWFP Agricultural University Peshawar Pakistan. One hundred and sixty, day old broiler chicks were randomly assigned to four treatments, as A, B, C, receiving 20, 30 and 40 mL of 6% (w/v) concentrated aniseed infusion and D was kept as control group. Each treatment was replicated four times with ten chicks per replicate. Chicks were reared in cages in an open sided house. Vaccination was done against ND and IBD. Data were recorded for growth performance, immunity and economics. The data were subjected to statistical analysis, using Completely Randomized Design and MSTATC programme. Mean feed and water intake was nonsignificant (p>0.05). Mean weight gain, FCR and dressing percentage was found better (p<0.05) in group C. Mean weight of giblet, intestine, breast, fat and thigh was not altered (p>0.05) in all groups. Mean antibody titer against IBD was higher (p<0.05) in group C and antibody titer against ND and IB was not altered. Mean percent mortality was found higher (p<0.05) in group D. Mean feed cost including the cost of aniseed infusion was not influenced (p>0.05), while the gross return was found better (p<0.05) in group B and C than other groups. Findings of the research study indicated that group C, receiving aniseed infusion at the rate of 40 ml L-1 of water shown better growth performance, immunity and gross return. Detail research work is needed to examine the effect of aniseed in ration and its different form of extracts on poultry production under different environmental conditions.
