Effect of supplementation enzymes to laying hen diet containing local canola meal on some qualitative traits of egg

Abstract

The objective of this experiment was to study the effect of supplemention enzymes ( ROKSAZYME )200 g /ton . to deits contain local canola meal (CM), (15, %20 ) in laying diets.A total of 72 ISA-Brown strain hens 30 weeks old were used .The experiment period was 88 days. Hens were randomly assigned to six replicates (3 hens /replicate).All birds were fed Iso caloric and Iso nitrogenous diets that contain different levels of CM,Results of Supplementation ROKSAZYME diet contain canola meal showed no significant differences (P<0.05) in weight of shell, yolk, albumin, fatty acids ratio and level of cholesterol.
