Abstract

Thai Greenstem kenaf (Hibiscus sabdariffa) was grown locally and harvested to determine the chemical composition of plant components and the nutritional value of the leaf meal. Dry kenaf leaves analyzed 25.7% crude protein, 11.4% crude fiber, 3.3% ether extract, 49.1% nitrogen free extract and 10.6% ash. Kenaf supplementation to a ration containing 39.5% rice straw and 10% corn cobs was compared with dehydrated alfalfa meal supplementation. An estimate of digestibility, energy balance and nitrogen balance indicated that the digestibility of all nutrients except ether extract was significantly higher in wethers fed the kenaf ration. In contrast, nitrogen retention was significantly greater in wethers fed the alfalfa supplement (3.32 vs 2.05 g/day). Soluble protein in the kenaf and alfalfa rations was 29.4 and 23.7% of their total protein, respectively.
