Publisher: 2000Dissertation note: The present experiment was conducted to study the efficacy of different growth promoter antibiotics on the performance of broiler chicks.
Two hundred and forty day old broiler (Hubbard) chicks were purchased, kept in cages and were reared on six experimental rations designated as T1 (Control), T2 (Albac, Zinc Bacitracin, 50ppm), T3 (Flavornycin, Flavophosphlipol, 3ppm), T4 (Flavomycin, Flavophosphilipol, 6ppm), T5 (Flavomycin, Flavophosphilipol, 9ppm) and T6 (Lincornix, Lincomycin 4.4ppm) upto the age of 42 days. The starter rations were fed upto 28 days of age and the finisher from to 42nd days of age.
The results of the present study indicated significant difference in weight gain, feed intake, feed efficiency, total bacterial count of feed, total bacterial count of intestinal contents of chicks fed on antibiotic incorporated feed than control (un-medicated). The results of dressing percentage were non-significant.
Rations designated as T2 (Zinc bacitracin, 50ppm) and T3 (Flavophospholipol, 3ppm) showed non-significant difference for weight gain, feed consumption and feed efficiency, whereas the ration T4 (Flavophospholipol, 6ppm), T5 (Flavophospholipol, 9ppm) and T6 (Lincomycin, 4.4 ppm) showed non-significant difference for weight gain, feed consumption and feed efficiency. But ration T4, T5 and T6 showed significant difference with T2 and T3 for weight gain.
With respect to objective of the study, the economic picture of rations T1, T2, T3, T4, T5 and T6 for cost per Kg. of live weight gain (excluding cost of day old chick) were Rs. 17.86, 17.45, 17.39, 17.22, 17.38 and 17.37. Ration T6 was economical by Rs. 0.64, 0.23, 0.17, 0.16 and 0.15 with T1, T2, T3, T4 and T6 respectively. So the Flavomycin 80 at the rate 6ppm (Flavophospholipol) can be used in broiler starter and broiler finisher rations.

Publisher: 2004Dissertation note: The present study was designed to compare the efficacy of different anticoccidials available in market. Coccidiosis is a disease of universal importance in poultry production. A total of one hundred and eighty, day old broiler chicks were purchased and raised for 42 days in a healthy and good hygienic environment. The birds were then divided into 6 groups viz A, B, C, D, E and F having 30 birds each. Group C and D was given feed additive anticoccidial Kokcisan (salinomycin 12%) and Decocci (meduramycin 1%), while in group E and F was given a herbal drugs i.e. Urisool and Coxigon respectively. All the groups except group E were given challenge of infection on day 22. The oocyst count was done on 5th, 6th and 7th day after infection.
During the experimental period feed intake, weight gain, FCR, mortality rate, oocyst count, clinical findings and postmortem findings were recorded on weekly basis. Results showed that average feed intake was higher in group E i.e. infected and treated with Urisool (herbal coccidiostate). The result showed there is no statistical difference between herbal coccidiostates and other chemotherapeutic drugs. Average weight gain was higher in group E i.e. infected medicated with Urisol a herbal product gave better result.
The results of present study showed that salinomycin treated group is better among all groups regarding FCR. The herbal groups showed less percentage of mortality. The results are also in agreement with many scientists who reported that herbal anticoccidials are safe and has no side effects and tissue destruction. No toxicity and poisoning is observed even at higher doses as in ionophores and no resistance is developed towards any species of Eimeria. Oocyst count was also lower in both herbal treated groups. Almost all the birds receiving infection showed the clinical symptoms of coccidiosis, symptoms were more pronounced in birds of group (uninfected and unmedicated), salinomycin and meduramycin treated group. However, in groups treated with Urisol and Coxigon the signs were not much pronounced, which shows effectiveness of herbal preparations. On account of all these results, it is summarized that herbal anticoccidials are equal in efficacy as compare to other anticoccidials.
The results of this study will help to the feed millers in choosing best and economical feed additive anticoccidial.
