Abstract
The aim of the present study was to investigate the effect of the fermentation product of Streptomyces rimosus, in sugarcane molasses fermentation media, on broiler performance. The streptomyces fermentaion product (SFP) used herein contained 4% oxytetracycline. The product was added o broiler starter / grower and finisher diets at levels equivalent to 5,15,25, 35 and 55 ppm oxytetracycline and compared to the addition of terramycin (10%) as recommended. The feeding experiment was carried out in the summer time where the temperature ranged from 35 to 38°C. Results obtained were as follows 1)The dietary addition of terramycine or SFP did not show significant effect on growth performance of the experimental chicks. 2)The chicks fed on the diet without addition showed high mortality rate. 3)The addition of terramycin did not decrease mortality rate of chicks. 4)The addition of SFP at the the levels equivalent to 45 and 55 ppm ox-y tetracycline markedly decreased mortality rate. 5)Blood Total Protein, Albumin, Globulin, Glutamic Pyruvic Transferase, cplutamic-Oxaloacetic Treansferase and Alkaline phosphatase did not show special trend among different treatments. 6)Values of Intestinal Thickness Index showed that the addition of terramycin or SFP at the levels equivalent to 15, 25, 35, 45 and 55 ppm Oxytetracycline decreased it significantly. 7)No residual Oxytetracycline was detected in the muscle or the liver of chicks, however, there was no withdrawal period before slaughtering chicks at 7 weeks of age.
