Efficacy of Lactic Acid Bacteria Probiotics on Feed Efficiency and Carcass Weight in Kampung Unggul Balitbangtan (KUB) Chicken

Abstract

This study aimed to determine the effect of lactic acid bacteria probiotics on the performance of Kampung Unggul Balitbangtan (KUB) chicken. A total of 48 KUB chickens aged 2 weeks were randomized into 4 treatments and each treatment consisted of 12 chickens. This study was conducted for 8 weeks. This study used 4 different treatments including (P0) not using probiotics, (P1) using probiotics of 1 mL/L drinking water, (P2) using probiotics of 2 mL/L drinking water, and (P3) using probiotics of 3 mL/L drinking water. The data were analyzed using ANOVA continued with Duncan’s Multiple distance test. As a result, reported that the data had a significant difference in the increase in feed efficiency and carcass weight. In conclusion, the administration of probiotics of 3 mL/L of drinking water can increase feed efficiency and carcass weight in KUB chickens.
