Feeding systems to control heat stress in laying hens on Brown Island in Junín, Ecuador.

Abstract

In the poultry farm "La Herminia" located in the Junín canton of the Manabí Province in the year 2007 - 2008, the present investigation was carried out, which consisted of supplying feed to laying hens (Isa Brown) at different times of the day to reduce heat stress, in our environment the existing changes in the metabolism of birds are not yet controlled by having a reduction in voluntary feed consumption, which affect both egg production and shell quality, egg weight, factors that put Manabí farmers at a commercial disadvantage and generate large losses, which is why it causes concern since poultry farming is an important item for producers. The aim was to determine the best feeding system that would favor feed conversion and determine the cost-benefit of the treatments. The treatments used were: 30-70; 70-30; 60-40; 40-60; and the control 50-50. The treatment with the highest feed intake was 30-70, with no statistical significance regarding egg weight, and the highest voluntary feed intake by the hens was in the afternoon.
