Abstract
Fifty-one Angora goats were randomly assigned to two treatment groups, drylot and pasture, with three feed regimes per treatment to study the effect of encapsulated methionine (EM) on mohair production and quality traits. In the drylot group the goats were continuously maintained in drylot with feed provided daily to each of the three pens as follows: (1) 3.63 kg ground oats plus 72 g EM, (2) 2.90 kg ground oats plus .73 kg cottonseed meal (CSM) and (3) 3.63 kg ground oats. Each pen was also fed approximately 9.00 kg sudangrass hay per day. In the pasture group the goats were relegated to native pasture. The goats were penned at night and divided into three pens with feed provided daily to each of the three pens as follows: (4) 1.81 kg ground oats plus 72 g EM, (5) 1.45 kg ground oats plus .36 kg CSM and (6) 1.81 kg ground oats. Drylot goats were heavier (P<.01) than pasture goats during the first shearing period (112 days) but not during the second shearing period (168 days). There were no significant differences in body weight between the three feed regimes within the drylot and pasture groups for the initial and first shearing periods. During the second shearing period goats in the drylot group receiving oats plus EM were heavier (P,.01) than goats receiving either of the other two feed regimes. Within the pasture group goats receiving oats were the heaviest (P<.01).
