Abstract
The objective of this experiment was to determine effects of substituting concentrate mixture (CM) with water hyacinth (Eichhornia crassipes) leaves (WHL) at different inclusion levels of feed and nutrient intake, digestibility, and growth performance of Washera sheep. Twenty yearlings intact male sheep with initial body weight of 24.1 ± 1.68kg (mean ± SD) were used in both 90days of feeding and 7days of digestibility trials. The experimental animals were arranged into four blocks of five animals based on their initial body weight. The dietary treatments used in the experiment were 100% concentrate mix (0WHL-T1), 50% WHL and 50% CM (50WHL-T2), 75% WHL and 25% concentrate mix (75WHL-T3), and 100% WHL (100WHL-T4). Rice straw was given ad libitum. The crude protein (CP) content of water hyacinth leaf is 14.4%. Dry matter digestibility was greater (p < 0.001) for 0WHL and 50WHL followed by 75WHL. The average daily weight gain was higher for 100% concentrate mix followed by 50 and 75% water hyacinth leave supplemented sheep. Therefore, wilted water hyacinth leave can safely substitute concentrate mix up to 75% and result in the optimum growth of Washera sheep from the feeding regime employed in this study.
