Abstract |
This study was conducted to investigate the effect of different levels
of Protexin on feed efficiency and egg laying traits of Japanese quails.
Forty eight Japanese quails (Coturnix japonica), having average
age six weeks were equally allocated to four treatments each containing
three replicates. In each replicate were included three female and one
male bird. Birds received diets which were supplemented with 0, 0.250,
0.500, and 1.000 gm Protexin per kg diet as control, treatments 2, 3 and
4 respectively. Feed intake was measured daily and feed conversion ratio
was calculated. After 63 days of experimental period, egg weight,
albumen weight, yolk weight, and shell weight were measured. Feed intake
decreased significantly in group 3, while FCR decreased significantly in
all treatments. Egg weight, shell weight, albumin weight increased
significantly in group 3. However, yolk weight decreased significantly
in group 4. In conclusion, Protexin at the level of 0.500 gm/kg of feed
improved the egg traits in Japanese quail.
