Effect of Poly herbal Phytobiotic on the Growth, Immunocompetence, Development of Digestive Organs and Carcass Characteristics of Commercial Broilers
Abstract:
Seventy two, one week old, Cobb 400 broiler chickens were distributed into two experimental groups having four replicates. The birds of the control group were fed a basal diet (22.5% CP & 2830 K cal/kg ME) while the other group was offered a basal diet supplemented with a polyherbal phytobiotic, AV/SSL/12 in drinking water@ 4 ml/100 birds/ day during 1-2 weeks, 8 ml/ 100 birds/ day during 2-4 weeks and 15 ml/100 birds/ day during 4-6 weeks of age. AV/SSL/12 birds had a significantly higher (P<0.05) body weight compared to the control at 2nd week of age. The body weight gain of the birds in the liver tonic fed group was significantly higher (P<0.001) compared to the control group at 2nd week of age. Feed conversion ratio (FCR) was significantly better (P<0.05) in the phytobiotic group compared to the control group during 3-6 weeks and 1-6 weeks of age. Total immunoglobulins and mercaptoethanol sensitive (IgM) antibody titer (log 2) values in response to sheep red blood cells was significantly higher (P<0.05) in the phytobiotic compared to the control group. The herbal supplemented group had significantly higher (P<0.05) large intestine length compared to the control group at 6 weeks of age. However, there was no significant difference between the treatment groups in the carcass characteristics and yield of cut up parts of the broilers after 6 weeks of age. Hence, it may not be unreasonable to infer that poly herbal liver tonic, AV/SSL/12 possesses promising immunomodulatory potential and supplementation of poly herbal liver tonic may elicit growth of commercial broilers.
