Perbandingan Populasi Mikroba Patogen dan Non Patogen pada Feses Ayam Petelur yang Diberi Ransum LCPD (Low CrudeProtein Diets)

Abstract

The research aims to determine the total population and TPC ratio of pathogenic and non-pathogenic bacteria in the feces of laying hens given a ration with a protein content reduced to 15%. The research was carried out in May-July 2022 at the ISA Brown Laying Chicken Farming Unit. The research was designed using a Completely Randomized Design (CRD) consisting of 2 treatments 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 and excreta collection was carried out on 4th week and 8th week of observation. The variables observed were TPC/Total Population Count on pathogenic and non-pathogenic bacteria and ammonia excreta production. The results of the study showed that reducing ration protein levels to 15% significantly (P<0.05) reduced the total population of pathogenic bacteria and had implications for reducing excreta ammonia (NH3) levels. It was concluded that the LCPD strategy could reduce excreta ammonia levels through the degradation of TPC of pathogenic bacteria.
