Year: 2025

Type: article

Abstract: This experiment was conducted to determine the effect of different levels of fish meal on the incidence of gizzard lessions and ulcerations and percentage of mortality. A totla of 348 day old chicks were randomaly assigned to the three treatment (treatment represent 0.0 , 6.6 and 13.3% fish meal ) with four replicates per treatment. Chicks were fed ad libitum from day-old to 7 weeks of age. The results of this experiment indicated that the correlation coefficients between scores of infection severity and body weight, weight gain , feed intake and feed conversion ratio was —0.750, -0.750, -0.494 and 0.177 at 4 weeks of age, but it was -0.877 , -0.858 , -0.764 and 0.795 at 7 weeks of age respectively. The percentage of infection was 0.0 , 25 and 75% While, the infection severity was 0.0 , 1.3 and 3.0% . However, percentage of mortality was 1.80 , 5.0 and 12.5% for birds fed on diet containing 0.0 , 6.6 and 13.5 % fish meal respectively. It can be concluded that the increasing this kind of fish meal in the diet up to 13.3% 1ed to depressed broiler performane due to gizzerosine factor, which is resulting from the high temperature that had been used in fish meal processing.
