THE EGG QUALITY OF NATIVE CHICKEN’S WITH VITAMIN E SUPPLEMENTATION IN RATION CONTAINING MANHADDEN FISH OIL AND KERNEL PALM OIL

Abstract

The experiment was conducted to detennine the effect of manhadden fish and
kernel palm oils and their combination with different levels of vitamin E on the egg
quality (egg weights, egg production/Hen Day Production, Haught Unit/HU, egg index, yolk colour, egg strength, cholesterol, High Density Lipoprotein, Low Density
Lipoprotein, and egg yolk triglyceride). This research was done in Laboratory of
Animal Feed Department of Animal Feed and Nutrition GMU, Yogyakarta. Laboratory
of Animal Feed and Nutrition and Experimental Sub-station Faculty of Animal Sciences UNSOED, Purwokerto. The Research consisted of two steps of experiment which carried out from April 2004 to November 2005. fourty five hens and 20 cockerels of 22 weeks old native chicken were used in the experiment and they were kept for five months. Experiment design used was Completely Randomized Design (CRD), each treatment was repeated 6 times, Data then were analyzed using analysis of variance continued with Duncan Test. The rations of the study at first step were: R0 = 0% manhadden oil and 0% kernel palm oil; R1 = 10% manhaden oil and 0% kernel palm oil; R; = 5% manhadden oil and 5% kernel palm oil; R3 = 0% manhadden oil and 10% kernel palm oil, where the second experiment used : R31 = basal feed + 0 mg vitamin E /kg of feed ; R3; = basal feed + l0 mg vitamin E /kg of feed; R33 = basal feed + 20 mg vitamin E /kg of feed; R34 = basal feed + 30 mg vitamin E /kg of feed. The result showed that the first step of treatment did was not significantly (P>0.05) affect egg index, yolk colour, cholesterol, HDL, and egg yolk triglyceride), but was very significantly (P<0.0l) affected egg weights, HU, egg strength, and egg yolk LDL. The second step showed that the treatment was not significantly (P>0.05) affect HU, yolk colour, egg strength, cholesterol, HDL, LDL, and egg yolk triglyceride, but was very significantly (P<0.0l) affect egg weights, HDA, and egg index. It can be concluded that vitamin E addition in ration containing manhadden fish and kernel palm oils improve the egg weights, egg production/HDA, and Haught Unit. In the other hand vitamin E addition reduced cholesterol, triglyceride and LDL of yolk.
