THE EFFECT OF DIETARY SUPPLEMENTATION OF SELENIUM ON THERMOREGULATION AND EGG QUALITY OF QUAIL HENS
Abstract
ABSTRACT The study was conducted to access the effects of dietary supplementation of selenium on thermoregulation and egg quality of quail hens. A total of 20 quail birds at 4 weeks of age with an average weight of 140g were allotted to 4 treatments with 5 birds per treatment. The treatment comprises of control (0% selenium), 1% selenium, 2% selenium and 3% selenium. Respiratory-rate (RR) and Cloaca temperature (CT) were observed at 2 days interval weekly for the entire duration of the study. The study lasted for 8 weeks. Egg qualities of experimental birds were evaluated twice in a week. Data was subjected to one-way Anova. Duncan Multiple Range was used to separate treatment means with p0.05) on RR and CT. Egg weight, albumen weight and yolk weight of birds fed selenium especially at 2% - 3% were significantly higher (p
