Influence of Flavomycin on Performance and Egg Quality of Laying Hens

Abstract

The present experiment was conducted to evaluate the effect of different levels of flavomycin on performance and egg quality of layer hens. Ninety commercial layer hens (White Lohmann) at the age of 63 weeks were used .The duration of the experiment was seven weeks. Birds were randomly assigned to three dietary treatment groups of thirty hens each. The treatments included 100 and 150 gm flavomycin/ton feed (8 and 12 ppm of flavophospholipol respectively). Each treatment was subdivided into six replicates of 5 birds each. All experimental diets were formulated according to the guidelines given in the manual provided by the breeder company Layers Performance and parameters of egg quality were recorded. The results indicated that the addition of flavomycin to diet significantly improved (P<0.05) egg weight values throughout the experimental period. No significant differences were observed in the performance of all treatment groups (feed intake and egg production) and egg quality. It is concluded that dietary supplementation with flavomycin, in inclusion rate of 8 ppm, enhanced egg production as well as egg weight of aged commercial laying chickens
