Abstract
In this study effects of dietary goji berry (LyciumbarbarumL.) leaf (GBL)
meal on egg rate, feed intake, egg yield and mass, feed conversion ratio,
external and internal egg quality and egg yolk cholesterol level of laying
hens were investigated. A total of 55 Lohman Brown laying hens aged 48
weeks were used. The birds were fed with basal diet supplemented with 1
g/kg (GBL1), 5 g/kg (GBL5), 10 g/kg (GBL10), 20 g/kg (GBL20) of goji
berry leaves and negative control. These mentioned doses were added to
per kg basal diet (166 g crude protein and 2821 kcal ME kg-1
). Feed was
offered limited (110 g/hen) and water was available ad-libitum. The trial
was continued for 8 weeks. At the end of the study, egg yield, egg mass,
feed intake and feed conversion ratio of laying hens were not affected by
treatments with the addition of GBL (P>0.05). Whereas GBL20 treatment
reduced the yolk cholesterol level (P<0.05). GBL10 and GBL20
decreased egg shell thickness compared to control group (P<0.05).
GBL10 increased albumen index compared to control group (P<0.05). As
a result, 20 g/kg GBL was used in layer diets as a feed additive to reduce
egg yolk cholesterol levels
