Egg Production and Quality of Quails Fed Diets with Varying Levels of Methionine and Choline Chloride
Abstract: The aim of the
present study was to determine the effect of choline chloride supplementation
at 1500 ppm in diets containing various levels of methionine on egg production
and egg quality in quails. A total of 180 birds, at 6 week-old quail were
divided into 18 experimental units, and assigned to a 2 x 3 factorial design
experiment with 3 replications (10 birds each) in each treatment. The birds
were offered diets containing choline chloride at either 0 (A1) or 1500 ppm
(A2), with three levels of methionine namely, low (0.19%, B1), standard (0.79%,
B2) and, high (1.05%, B3). The feeding trial lasted for 8 weeks.
Supplementation of choline chloride in low methionine diet significantly
(P<0.05) increased egg production, egg mass, and egg weight as compared to those
without choline chloride supplementation. Supplementation of choline chloride
significantly (P<0.05) increased egg yolk weight but decreased albumen and
egg shell weight as compared to those fed diets without choline chloride
supplementation. It can be concluded that supplementation of choline chloride
to a diet containing low methionine increased egg production, without affecting
egg quality.
