PERFORMANCE OF DUAL-PURPOSE CHICKENS EXPOSED TO TEMPERATURE VARIATION AND CORIANDER SEED POWDER (Coriandrum sativum) SUPPLEMENTATION

Abstract:

Two consecutive experiments were conducted with the objective of evaluating the performance of Koekoek and Sasso T44, exposed to temperature variation with coriander seed supplementation. The first experiment was conducted with the use of growers at an age of 9-20 weeks and the second experiment was continued from week 21 to 40 (layers phase). In both experiments, groups of Sasso T44 and Koekoek breeds of growers and layers were exposed to two different room temperature (heated and normal rooms) with the supplementation of three levels (0,5 and 10 g/kg) of coriander seed powder. Each treatment was replicated three times. A total of 756 growers (378 of each breed) in the growers experiment and 504 of pullets in the layers experiment were used. The results indicated that significantly lower (P
