The experiment was conducted to study the effects of feeding different ratio of concentrate and roughage to growing-fattening Korean native steers with 1 S heads. The treatment were composed of 3 groups of T₁ (concentrate to roughage ratio, 80:20), T₂ (concentrate to roughage ratio, 70:30) and T₃ (concentrate to roughage ratio, 60:40). The results obtained were summarized as follows: 1. Average daily weight gain of T₁, T₂ and T₃ for period 1, period 2 and period 3 were 0.78, 0.84, 0.76; 0.92, 0.92, 0.93; and 0.83, 0.87, 0.78; respectively. The daily gain of T₂ group was significantly higher than that of T₃ group for total period. 2. The digestibility of crude protein and NFE of different groups showed little variation, however, and that of crude fiber decreased significantly as the ratio of concentrates increased for all 3 periods. 3. The daily TDN intake of T₁, T₂ and T₃ groups far total period were 5.15, 5.56 and 5.53 ㎏, respectively, indicating more consumption for T₂ group. 4. The TDN requirement of T₁, T₂ and T₃ groups for total period were 6.11, 6.35 and 6.48, respectively. 5. The dressing percentage and edible; parts percentage of T₁, T₂ and T₃ groups were 61.2, 51.0; 61.5, 50.0 and 58.9, 48.6, respectively, showing lower percentage for higher roughage group.

A digestion trial with four wether lambs and a feeding trial with sixteen Holstein cows of late lactation were conducted to evaluate nutritive value of soyhull and its feeding value to lactating cows. Digestibility of dry matter, crude protein and crude fiber were 78.0, 69.9 and 74.0%, respectively and total digestible nutrient content of soyhull was about 68.8%. When soyhull was included in dairy concentrates for replacement of the same amount of corn at the levels of 5.5, 11.0 and 16.5% of concentrates (fed about 7㎏ a day), milk production gradually decreased but milk fat content was increased. When milk production per unit concentrate or total feed consumed was calculated soyhull was as efficient as corn in providing energy for milk production but the energy content of soyhull was lower than that of corn, which caused slightly lower milk production in cows fed a limited amount of concentrates containing soyhull.

In order to study the effects influencing the digestibility of crude fiber as an index for improving the consumption and availability of rice straw according to the quality and quantity of concentrate the feeding and digestion trial was carried out employing Japanese castrated goats at the grow ing stage. 1. Japanese native goats were fed 100g concentrate per day which contained 6.4, 11.7, 12.0 and 17.0% DCP in experiment 1. There were no significant difference in rice straw intakes of goats treated. However, the significant difference in digestibility of crude fiber (P$lt;0.05) was found. The digestibility of crude protein increased as the level of crude protein increased (P$lt;0.01). 2. The consumption of rice straw decreased according to increasing consumption of concentrate (P$lt;0.01) in experiment 2 designed for varying the supply of concentrate which contained 11.7 DCP in the levels of 500, 375, and 250g per day. The digestibility of nutrients except the crude fiber increased as the consumption of concentrate increased. However, the digestibility of crude fiber showed reverse effect compared to the nutrients (P$lt;0.01). 3. The multiple regression was studied between the dry matter digestibility and DCP intake, TDN intake, rice straw intake and DM intake: Y=40.1265+1.076TDN-0.472DCP-0.065RSIN* The multiple regression between the crude fiber digestibility and those above mentioned as follows: Y=26.7905-3.684TDN+38.316DCP**-0.138RSIN**+0.382DMIN. And that between digestibility of crude fiber and those were as follows: Y=38.886-4.356TDN**+26.545DCP**+0.0038RSIN-0.0297DMIN. 4. The linear regression between TDN consumption per ㎏ body weight and digestibility of crude fiber was established as follows: Y=68.33-1.142X The optimum TDN consumption per ㎏ body weight was estimated as 14g for digestion of crude fiber. 5. Between DCP consumption per ㎏ body weight and digestibility of crude fiber the following equation was found: Y=60.82-6.408N The optimum DCP consumption per ㎏ body weight eras found as 1.2g for digestion of crude fiber.
