18. Dose dependence studies of Aniseed (Pimpinella anisum) and Ginger (Zingiber officinale) extract mixture on growth promoting and immunomodulatory effects in broiler chicks
Main Article Content
Abstract
Dose dependency studies (2gms + 4gms), (2.5gms + 5gms) and (3gms + 6gms) allowed us to observe dose dependent responses of aniseed and ginger extract mixture in drinking water on the immune response and over all performance of broiler chicks. Two hundred and forty (240), day old broiler chicks were randomly distributed into four groups, designated as A, B, C and D and each group was further divided into two subgroups. Each subgroup was replicated three times each with 10 checks per replicate for different treatments. One of the subgroup was vaccinated with new castle disease (ND), infectious bronchitis (IB) and infectious bursal disease (IBD) vaccine according to the schedule. Group A was kept as a control, while group B, C and D were treated with an extract mixture of aniseed and ginger at the rate of (2gms + 4gms), (2.5gms + 5gms) and (3gms + 6gms)/litter of drinking water respectively. Body weight and feed conversion ratio (FCR) were significantly (P<0.05) better in group D as compared to other groups. Non-significant (P>0.05) difference was recorded in mean feed intake and water intake. Mean antibody titer against ND, IB and IBD was significantly (P<0.05) better in group D and vaccinated groups as compare to other groups. It is concluded that extract mixture of aniseed and ginger @ (3gms+6gms) added in poultry birds drinking water is better for increasing body weight gain, best FCR and improving immune response. Similarly, it is comparatively safe, free of side effects, eco-friendly and locally available.
