EFFECT OF LINSEED OIL IN THE DIET ON EGG PRODUCTIVITY AND QUALITY OF ISA SHAVER LAYING HEN

Abstract

The experiment was carried out on 270 Isa shaver laying hens from 49-56 weeks of age, were divided into three treatments, each treatment was repeated 3 times with 30 hens/group (30 x 3 = 90 hens/treatment). Linseed oil was added to the rate of 0, 0.5 and 1% in diets of laying hens without balancing of energy and feed for feeding. The results showed that: adding linseed oil in the diet was increased the live rate, egg production/hen, was reduced feed consumption per 10 eggs and the cost of feed per 10 eggs, with significant different between treatment 1 with control treatment and treatment 2 with P < 0.001, but no significant different between treatment 2 with control treatment with P > 0.05. Supplying 0.5% linseed oil into the diet did not effect on egg weight but also increases the rate of egg yolk, egg shell, but reduced egg white, thereby increased the rate of egg yolk per egg white. However, at the rate of 1% linseed was added to the diet reduce egg weight, egg yolk, egg shell, but increase the rate of egg white to compared with control treatment
