EFFECTS OF DIETARY L-CARNITINE SUPPLEMENTA-
TION ON EGG PRODUCTION AND EGG QUALITY
There are several factors influencing the quality and quan-
tity of eggs. Among these, the most important factors are
nutrition, disease, age, breed or strain of bird and environ-
ment. Many important egg-quality components were deterio-
rated and become more variable with the age of the bird.
Nutritional factors can modify egg quality by inducing meta-
bolic changes. In fact, reports on the effects of dietary L-car-
nitine on egg production and egg quality of laying hens are
limited. LEIBETSEDER [39] has reported that egg hatchabi-
lity increased from 83 % to 87 % and from 82.4 % to 85.3 %
in broiler breeders supplemented by L-carnitine at 50 and
100 mg/kg diet respectively.
