Production Performance and Egg Quality in Native Chickens Fed Diet of Skipjack Fish Oil

Abstract

The objective of the experiment was to investigate the production performance and egg quality in native chickens fed diet of skipjack fish oil. Two hundred native chickens 36 weeks of age, was use in this study for 8 weeks experiment. These were assigned by a completely randomized design with five dietary treatments, five replications and 8 native chicken in replication each. The data were analyzed using analysis of variance followed by Duncan’s multiple range test. The diets were: R0 = 100 % Based Diet (BD) + 0 % Fish Oil (F0); R1 = 98,5 % BD + 1,5 % F0; R2 = 98 % BD + 2 % F0,R3 = 97,5 % BD + 2,5 F0; R4 = 97 % BD + 3 % F0. Feed and water were provided ad libitum. Feed consumption was measured weekly and FCR was calculated at the end of the trial. A total of 25 egg yolk samples of day 28 (n= 5 egg yolks for each treatment) were collected to analyse the egg quality native chickens. The results showed that Feed Intake, Hen Day Production, Eggmass, Feed Conversion, Eggshell weight, Egg Shell Thicknes, Egg yolk weight, Egg Color, Egg Cholesterol were significantly affected by skipjack Fish Oil, but did not significantly affect to egg weight, Haugh Unit, Shape index. It can be concluded that the use of fish oil in diet up to 3 % could improve production performance and egg quality in native chickens.
