Abstract
Two experiments were conducted to evaluate the effect of Echinacea powder (EP) supplementation of a layer diet on the laying performance and reproductive properties of both Sinai laying hens and cocks. In Experiment 1, one hundred and thirty two laying Sinai birds (120 ♀+ 12 ♂) at 35-wks-old were weighed and randomly distributed into four experimental groups, as follow, the basal diet, the second was supplemented with 1g EP / kg diet, the third was supplemented with 2g EP / kg diet, the fourth was supplemented with 3g EP / kg diet. In Experiment 2, ninety six of Sinai birds (36 ♂ + 60 ♀) were weighed and randomly distributed into same four experimental groups to feeding the cocks only) 9 cocks / treatment distributed in 3 three replicates( while the all hens were fed on the control diet. In experiment 1, no significant alternations were reported in egg number /hen, egg weight and egg mass due to using any of the dietary treatments. But, the results confirmed the superiority of diet supplemented with 3g EP/ kg diet to hatchability of set and fertile eggs as it was significantly greater (P≤0.05) than control group. In experiment 2, the diets supplemented with different levels of EP recorded significantly (P≤0.05) higher values of fertility percent than control diet. Also, hatchability of set eggs% was significantly (P≤0.05) increased by feeding on diets supplemented with 1 and 2 g EP/kg diet compared to the control diet. Thus, the Sinai cocks fed diets supplemented with 1 and 2g EP/ kg diet as an antioxidant can be used to enhance cock's welfare, fertility, and hatchability percent and to improve the economic efficiency.
