The Effect of Capsulated niacin supplementation on Cholesterol profile and EggProduction of Hysex Brown Laying Hens

Abstract

The aims of this study was to evaluate the effect of capsulated niacin supplementation on cholesterol profile and egg production of Hysex Brown laying hens. This study was conducted based on Completely Randomized Block Design with four treatments of capsulated niacin containing 0,500, 1.000, and 1.500 ppm and five replication that were was given orally to individual hens per day. In each replication, there were four hens aged 30 weeks. The formulation diet of 2.900,01 kcal ME/kg, 16.5% of protein and drinking water with ad libitum were given during 12 weeks observation. The result showed that the effect of niacin supplemen-tation until 1.500 ppm did not show any significant effect (P>0.05) toward feed intake, egg production, egg cholesterol, plasma cholesterol, estrogen and thyroxin during 12 weeks of observation. When the hens reach the age of 34 weeks, it was found that 1.000 and 1.500 ppm niacin supplementation significantly (P<0.05) reduced plasma and egg cholesterol by 10. 45 and 19. 22 % and did not affect the eggs production. It was concluded that niacin supplementation until 1.500 ppm did not affect cholesterol profile and egg production of Hysex Brown laying hens.
