Feed flavor was added to whole milk and to calf starter to determine the effect of feed flavor on the starter consumption and growth of calves. Twenty four calves aged 4 days old were arranged randomized completely to 4 treatments and 6 calves per treatment. Calves received whole milk from birth to weaning at 46 days. Starter was offered ad libitum from day 12 to 46. Feed flavor was added to whole milk ar 120㎎/㎏ and starter at 0.1% Cowmilk Feednectar, 0.05% Sugarmate Feednectar and 0.05% Cowmilk Feednectar + 0.05% Sugamate Feednectar, and the results were summarized as follow: 1. Average birth weight of 24 calves was 42.77㎏ and the growth rate from birth to 46 days old was 0.353㎏ in average. 2. Average daily starter consumption from day 12 to 46 after birth was 310g in control group, 320g in Cowmilk Feednectar, 306g in Sugarmate Feednectar and 319g in Cowmilk Feednectar + Sugarmate Feednectar, respectively. 3. Average dally growth rate of calves from 12 to 46 days old was 417g in control group, 4918 in Cowmilk Feednectar, 4348 in Sugarmate Feednectar and 4378 in Cowmillc Feednectar + Sugamate Feednectar, respectively. Calves received feed flavor in starter gained more weight than those not fed feed flavor. 4. Addition of feed flavor in whole milk encouraged slightly to eat more starter which also contained same feed flavor.

The most effective chemicals on a weight basis in increasing in vitro dry matter digestibility of barley straw were NaOH followed by KOH and N₂CO₃, and Ca(OH)₂ or NH₄OH was least effective. The in vitro dry matter digestibility of barley straw increased with increasing concentration of chemicals, but the response of Ca(OH)₂ and NH₄OH treatment were very small extent. Increasing temperature increased significantly the digestibility of barley straw except Ca(OH)₂ which slightly decreased the digestibility of barley straw. The solubility of barley straw increased and cell wall constituent of barley straw decreased by increasing concentration of NaOH, but acid detergent fiber, cellulose and lignin content of barley straw were not changed The moisture content of barley straw which was treated with 5 % NaOH markedly influenced on the solubility and digestibility of barley straw. The solubility and in vitro dry matter digestibility of barley straw increased by increasing moisture content.
