The effect of using molassed-treaded dried brewer's spent grain in some productive and metabolic indicators of mountains goat kids

Abstract

the research was carried out at ''Era'' Research station for improving mountain goat breed in of General Commission for Scientific Agriculture Research in sweida (As-Suwayda) Governorate for the year 2021, with the aim of studying the effect of molasses-treated dried brewers' spent grain in some productive and metabolic indicators when introduced into the diets for fattening mountain goat kids.

The fatting experiment was conducted on randomly selected weight-homogeneous 18 mountain goat kids divided equally into three group, with 6 kids for each group . At a specific percentage for each group ( 0-20-30% , respectively) within the experiment duration, molasses- treated dried brewers' spent grain was introduced regularly into the provided concentrated diets for fatting . After weighing the remaining diet and calculating the consumed quantity  , and weighing the lambs every 15 days until the end of the experiment, a significant difference was observed in the amount of consumed feed, filled feed, live weight and daily growth rate between the comparison groups, noting the superiority of these indicators in favor of the experimental groups, especially the third group (p<0.05), and there was no significant difference in the feed conversion factor and the percentage of protein needed to produce 1 kg live weight (p>0.05) between the previous groups with the extent of these two indicators in favor of the experimental groups.  Therefore, the result indicate the efficiency of introducing molasses- treated dried brewers' spent grain into diets for fattening mountain goats, and thus its positive effect on the consumed feed and live weight.
