PENGARUH PENAMBAHAN ZAT ADITIF (ENZIM DAN ASAM ORGANIK) DENGAN PROTEIN TINGGI DAN RENDAH PADA PAKAN BERBASIS DEDAK TERHADAP PERFORMAN KELINCI

Abstract

EFFECTS OF ADDITIVES ADDITION (ENZYMES AND ORGANIC ACIDS) WITH HIGH AND LOW PROTEIN IN RICE BRAN BASE RATION ON RABBIT’S PERFORMANCE. A research evaluating the effectiveness of enzymes and organic acids in the rice bran-based with different protein content on the production performance of weaning rabbits. This research was conducted in March to May 2014 at the Livestock Research Center Ciawi. One hundred and twenty rabbits Rex and Reza of 900 -1400g body weight. The design used was factorial (2x4) based on Completely Randomized Design (CRD) with 5 replications. Combinations treatment consisted of factors, namely the level of protein factor A: A1 = 14% protein and A2 = 18% protein and factor B the addition of additives (enzymes + Organic Acids) consisting of: B1 = Ration Basal; B2 = Ration Basal + Feed Enzymes; B3 = Feed Enzymes and propionic acid; B4 = Feed Enzymes and butyric acid. Variables measured were Feed Consumption, Daily Body Weight Gain, and Feed Conversion. Feed consumption in this research were 74.95 to 86.59 g/ head/ day. Analysis of variance showed that there were no significant effects of treatments on feed consumption (P> 0.05). Daily body weight gain of rabbits ranged from 11.73 to 16.74 g/head/day. There was a significant effect of treatment interaction on average daily body weight gain (P <0.05). Tukey test showed that Average Daily Gain (ADG) of rabbits fed  A2B3 16.74 g/ head/day (18% protein with the addition of enzyme and propionic acid) was significantly higher than the rabbits fed A1B3 11.73 g/head/day (14 % protein with the addition of enzymes and organic acids). The feed conversion in this research is about 4.93 to 6.60 g/head/day. There were significant difference among treatment on feed conversion (P> 0.05). It can be concluded that there is no need of additive supplement when the ration has fulfilled nutrient requirement on 14 % and 18 % protein.
