The Effect of Enzyme and Probiotics Mixture in Drinking Water with Protein Level Differences on Body Weights, Feed Conversion and Production index on Broiler

Abstract

This experiment was study of the enzyme and  probiotic in drinking water mixture was affected on body weight, feed conversion and production index in broiler. This experiment was carried out using 144 broilers, started at one day old and finished at 42 days of age, divided into 4 type treatment of three different level of protein. Experimental method was based on randomized complete design with twelve treatments, if differently, followed by orthogonal  polynomial. Type 1 (unit ABC) was treated with mixture of drinking water and amylase, protease and probiotic at day 3^rd through 5^th, day 14^th , day 21^st, day 28^th and 35^th ;  type 2 (unit DEF) was treated at day 7^th ,17^th, 27^th and 37^th ; type 3 (unit GHI) was treated day 21^th , day 28^th and 35^th ; type 4 (unit JKL) without treatment (control). The level of protein for group I of unit ADGJ was 19% of starter feed and 16% of finisher feed. The level of protein for group II  unit BEHK was 21 %of starter feed and 18% finisher feed. The variable used in body weight, feed conversion, production index at the 5^th and 6^th weeks of age. Result indicated that the body weight optimum was 1483.33 gram at the 5^th weeks of age and 1868,89 gram, feed conversion 1, 826 and production index 279,31 at the 6^th weeks of age. These findings were observed in the group of chicken given drinking, water amylase, protease and probiotic mixed with at day 3^rd trough 5^th , day 14^th , day 21^st , day 28^th and day 35^th ; The level of protein was 23% of starter feed and 21% of finisher feed. The mixture of enzyme and probiotic in drinking water was concluded to improve in body weight, feed conversion and production index of broiler. (Animal Production 3(1): 26-30 (2001)
