EFFECT OF PELLET CONTAINING CASSAVA LEAVES MEAL AT VARIOUS PARTICLE SIZE ON BROILER

Abstract

The addition of cassava leaves meal (CLM) in broiler rations in the form of  pellets require specific and uniform size because it will determine the characteristics of the material, especially the particle size plays an important role during the process of making ration (mixing and pelleting process).  Research has been conducted from March to October 2013 in the Laboratory of the Department of Animal Husbandry. The study aims to look at the characteristics of the pellet that containing cassava leaves meal by using a variety of screen sizes as well as its influence on metabolizable energy, nutrient digestibility, histology of the digestive tract and broiler performance. Research using a completely randomized design (CRD), with three treatments and seven replicates and each experimental unit consisted of nine broilers. The treatment applied is T1 = CLM  milled using screen of 2 mm, T2 = CLM milled using screen of 3 mm, and T3 = CLM milled using screen of 5 mm. Observations included physical characteristics of the pellets, nutrients digestibility, metabolizable energy, histology of ileum and broiler production performance. The data obtained were tested by analysis of variance and a further test usingDuncan's multiple range test. The results showed that CLM milled using 2 mm screen to produce a compact pellet characteristics and performance of broiler production is better than the screen size 3 and 5 mm and the pellet with CLM milled using a screen 2, 3, and 5 mm produce normal ileal tissue in broiler.
