Performa Ayam Petelur Isa Brown Yang Diberi Ransum LCPD (Low Crude Protein Diets)

Abstract

The research aims to see the performance produced by ISA Brown type laying hens which are given low crude protein diets. This research was carried out in a housing unit integrated with an Azolla pond. The research was designed using a Completely Randomized Design (CRD) consisting of 2 treatments, namely R17 (ration with a crude protein content of 17%) and R15 (ration with a crude protein content of 15%), each treatment was repeated 15 times. The variables observed were the performance of laying hens which included weekly and daily ration consumption, egg production and egg weight. Data was collected during 4 weeks of observation and then analyzed using analysis of variance (ANOVA) with the help of the SAS program. The research results showed that the use of low protein rations did not show a significant effect on consumption and weight of eggs produced, but had a significant effect on daily egg production (hen-day). It was concluded that reducing protein to 15% did not show better performance compared to the application of standard rations
