The Optimalization of Probiotic Based Liquid, Powder and Combination on Broiler Performance
AbstrakBroiler are live microorganisms that are given in adequate amounts to provide health benefits to the body. Probiotics are live microorganisms that have a good effect on the health of the host (broiler). The use of probiotics for broilers has a function to increase growth and feed efficiency. Giving probiotics in drinking water has the potential to help the digestive system in broilers. The general objective of this research is to examine the use of probiotics as an alternative to AGP (Antibiotic Growth Promoter) in broiler feed and drink. The experimental design used was Completely Randomized Design with 4 treatments and 5 repetitions, namely T0 = Control (Without Probiotics), T1 = Basal Diet + Probiotic Powder (50 mg/Kg), T2 = Drinking Water + Probiotic Liquid (1 ml/L) , and T3= Combination (Basal Diet + Probiotic Powder 25 mg/kg) with (Drinking Water + Probiotic Liquid 0.5 ml/L). Data were analyzed using analysis of variance and further test using LSD (Least Significant Different). Observations made Average Day Gain (ADG), Body Weight (BW) and mortality in broilers related to the use of probiotics. In the observation of body weight at the age of 7, 14, and 21 days, the addition of probiotics was significant. Observation of body weight at the age of 14 days in treatment T2 and T3 was significantly different. In the observation of Average Day Gain (ADG) at the age of 7,14, 21 and 28 days are significant. After further testing, Least Significant Different (LSD) in the grower phase (14 days) was significantly different in T2 and T3 treatments. In monitoring overall mortality for 28 days, the addition of prebiotics significantly reduced mortality compared to controls. The conclusion is that the addition of probiotics is significant in observing the performance of body weight, adg, and mortality. Giving probiotics had a significant effect (T2 and T3) on the addition of ADG grower.
