SUMMARY
The influence of different types of food in laying hens of Isa Brown genetic line bred
floor on performance to compete in the market were evaluated. Two treatments
comprised of five replicates each were evaluated, Design was used at random
(DCA), for which he worked with 250 laying hens 19 weeks reared age floor
thoroughly, each treatment had 125 chickens in a group (T1) the supply system 70%
(AM) 30% (pM), and in the other group (T2) the proportion 30% (AM) 70% (pM)
was studied. The variables evaluated were: Weekly Production (%), weekly egg
weight (g), weekly egg mass (kg) Feed intake (g / d), feed conversion (Kg / Kg)
Weight gain Hen (Kg) and economic analysis ($). The T2 group had the best average
in all evaluated variables (P<0.05). Similarly, the T2 earned less economic loss,
which was $0,13 per dollar. It is recommended to producers of laying hens kept in
floor distribute daily food in proportion 30% in the morning and 70% in the
afternoon.
