Influence of Dietary Natural Veterinary Medicine (Minyak Rajas) on Growth Performance and Blood Profile of Growing Roosters

The use of natural medicines to improve the performance of chickens is increasingly in demand by poultry producers as well as consumers because of their safety. This study aims to determine the impact of supplementation of natural veterinary medicine (viz., Minyak Rajas (MR)) through feed on the performance and blood profile of grower phase fighting roosters. Sixty (60) fighting roosters were raised in individual cages and randomly divided into four groups. The MR was administrated through feed with respective doses of 0, 0.1, 0.2, and 0.4 ml/kg/day for seven weeks. The results showed a significant (p<0.05) increase in the cumulative voluntary feed intake, the cumulative body weight, the average daily weight gain, and the feed conversion efficiency in MR administered groups as compared to the control group. The best performance was exhibited (p<0.05) by the 0.2 ml/kg/day treatment group as compared to the control and other treatment groups. Total erythrocyte count and mean corpuscular haemoglobin concentration (MCHC) were also found higher (p<0.05) in the 0.2 ml/kg/day MR treatment group when compared with the control group. However, other haematological and biochemical indicators remained unaffected by the dietary treatments and their values were in the normal range. In conclusion, the supplementation of natural animal medicine MR have a beneficial effect on the health and performance of the grower phase fighting roosters.
