THE EFFECTS OF DIFFERENT METHODS OF BREAKING BROODINESS ON THE LAYING PERFORMANCE OF NATIVE CHICKENS

The study was conducted to determine the effects of different methods of breaking broodiness on egg production, feed consumption, egg weight, feed conversion efficiency, and mortality of native chickens from October to December 2017 at Mindanao State University, College of Agriculture Poultry Project, General Santos City. A Completely Randomized Design (CRD) was used in the study with four treatments replicated three times. There were thirty six native chickens, three birds in each treatment and replication. Treatments used were Control (T1), Bathing the birds （T2), Lighting over the nest (T3), and Removal of eggs before sitting (T4). Birds whose eggs were removed before sitting had the highest (17.22%) hen- day egg production while those in untreated, bathed and lighted birds were 5.74,5.74, and 5.99%, respectively. The highest (4.79kg) feed consumer were birds whose eggs were removed before sitting compared to 2.44, 2.49 and 2.67kg in bathed, untreated and lighted birds respectively. Egg weight of untreated birds was 40.47g while those of birds whose eggs were removed before sitting, bathed, and lighted birds weighed 40.83,41.02, and 41.71g, respectively. Birds whose eggs were removed before sitting was the most efficient feed converter requiring 1.86 units of feeds to produce a dozen of egg compared to 2.85,2.89,and 2.97 units required by bathed, untreated, and lighted birds, respectively. Except in egg weights, there were statistically high significant differences among treatment means in all parameters of the study. All the methods did not cause mortality.
