Abstract
The superior of native chicken from Agricultural Research and Development Center (KUB) is a chicken selected by 6 generations. The purpose of this study was to examine the effect of Probiotic Bio L on production performance and quality of chicken eggs in the R & D Kampung Superior. The research method used was experimental using a completely randomized design (CRD). Treatment using 60 KUB chickens aged 22 weeks (Layer phase) Divided into 3 P0: feed according to the farmer; P1: concentrate (25%), corn (40%) and bran (35%); P2: P1 + Bio B 2 cc / 1 litre of water; the number of administration is 80-90 g / head / day. The results showed that the growth rate and egg production of P2 treatment were statistically significantly higher (P <0.05) when compared to treatments P1 and P0. Therefore, in terms of consuming P2 ration, it was the most efficient way of absorbing the feed given, with conversion of rations 3.44 was significantly lower (P <0.05) than other treatments. Likewise, with the chemical quality of eggs can increase egg yolk protein by 7.6% and reduce yolk fat content by 16.15%.
