EFFECT OF TREATED BARLEY STRAW BY BACTERIA (Cellulomonas Cellulases) AND CONDENSED MOLASSES SOLUBLE ON GROWTH PERFORMANCE OF BARKI LAMBS

Abstract

This study aims to investigate the ability of using Cellulomonas cellulases, with or without the addition of condensed molasses soluble (CMS), to improve the palatability and nutritional value of barley straw by studying the change in the chemical composition and fiber fraction, and then studying the effect of feeding treated barley straw with bacteria and CMS on the performance of Barki sheep. This study is divided into two experiments:

1. The first experiment (digestion or evaluation trail) The digestibility trial was carried out using twelve Barki rams aged 3-4 years with 43.57±0.58 kg average body weight. The animals were fed individually in metabolic cages. The digestibility trail lasted for 42 days, 35 days as an adaptation period and 7 days as a collection period for feces and urine nutrients digestibility, nutritive values, nitrogen balance, sodium and potassium balance, some blood serum metabolites, some rumen parameters were determined animals in this trail. Animals were divided randomly into three groups (four animals per group) as follows: Control: 50% CFM + 50% clover hay (CH) T1: 50%CFM + 50%treated barley straw (TBS) T2: 50%CFM + 33% treated barley straw + 17% CMS. The results obtained can be summarized as follow: a. Chemical composition for barley straw The bacterial treatment of barley straw (TBS) increased CP, EE, NFE, ash, GE, Na and K content as compared to untreated barley
