China is the country with more people and more land, faced with the pressure of population growth and land decrement. The potential of developing animal husbandry by increasing feed grain per capita is less and less. "Planting forage to feed livestock" is a sustainable industry with grain-saying, high efficiency, good quality and safety, accorded with the conditions of China. First, the natural, social and economical condition in southern area of China was analyzed, and the characteristics of production and utilization of forage were introduced in this paper. The natural condition in southern area of China was well suited for forage production. Forage was mainly planted on famland. Main herbage cultivars were annual or hibernal annual. Most of forage was directly utilized by herbivorous animal and fish. Second, The present situation, developmental trend and existing problems of forage industrialization were reviewed. The level of forage industrialization was low with a bright future. At present, the chief existing problems were lack of herbage cultivars of good quality, backward equipment, lagged techniques and low level of mechanization in forage processing with a short time and so on. Finally, the situation of production and utilization of forage was summarized.

This study was designed to estimate effect of wood vinegar on meat quality in old Layer which was low production and low economic value. The old layer chickens were used to resource for income increase of layer farm and protein supply. Two hundred forty Isa Brown chickens were assigned with control(Broiler feed), Treatment 1 (Broiler feed with addition of domestic wood vinegar $0.8\%$) and Treatment 2(Broiler feed with addition of foreign wood vinegar $0.4\%$). Feed intake of control group was lower 3g than other treatments. This is the reason of result that what organic acid in wood vinegar of treatment groups affect to feed digestibility, The different of chicken production was depended on ingredient and included value of wood vinegar in domestic and foreign. Foreign wood vinegar have organic acids which that functionally act sexual Pheromone so that promote endocrine matter. This is reason that old Layer chicken increase to egg production rate. Treatment 2 group effect to thigh meat rather than breast meat and improve to value of crude fat and meat color. The Meat quality and sensory test of thigh meat of foreign wood vinegar was better appraise rather than that of domestic wood vinegar. Because foreign wood vinegar make to fine of meat tissue and to decline cooking loss and also to increase juiciness and tenderness on sensory test.

This study was conducted from 2013 to 2014 to explore the feasibility of the cultivation of warm-season grass as an annual Korean forage crop, while concurrently evaluating the characteristics and forage production of warm-season grass in Korea. The experimental design was a randomized block design (RBD) with three replications. Five bermudagrass [Cynodon dactylon (L.) Pers.] cultivars, two teffgrass (Paspalum notatum Flugge) cultivars, and a Kleingrass [Panicum coloratum L.] cultivar were compared for forage production and quality in the middle region of Korea. After seeding, the numbers of days until seedling emergence for bermudagrass and kleingrass were observed at approximately day 11 and day 12, respectively. The heading dates of teffgrass and kleingrass were on July 12 and July 26, respectively. The dry matter (DM) yield of bermudagrass Tifton 85 was usually greater than the other entries. The crude protein content (CPC) and total digestibility nutrient (TDN) for the teffgrass cultivars were usually greater than the other entries at all study sites. The acid detergent fiber (ADF) and in vitro DM digestibility (IVDMD) were similar across all cultivars.

This study was designed to investigate the effects of pyroligneous liquor on lipid metaboilsm in serum of SPF/VAF Cri/Bgi CD rats. Male CD rats were fed basic diet prepared in our Lab., and PL-0 (control), PL-1, PL-25, PL-50, PL-75 groups were prepared with pyroligneous liquor (35% of Choa Co. Ltd.) of 0%, 1%, 25%, 50% and 75% in purified water per day for 8 weeks. Body weights and food intakes almost did not change in these five groups, and triglyceride (TG) levels were significantly decreased (20.5% and 19.5%, respectively) in these PL-25 and PL-50 groups compared with control group. Total and LDL-cholesterol levels were markedly decreased (20.7%, 16.3% and 20.3%, 116.9%, respectively) in these PL-25 and PL-50% groups, but HDL-cholesterol levels were significantly increased about 36.4% and 25.5% in serum of PL-25 and PL-50 groups compared with control group. Atherogenic indices were also remarkedly decreased (63.0%, and 50%, respectively) in these PL-25 and PL-50 groups compared with control group. These results suggest that long term administration orally of pyroligneous liquor in 25 to 50% may inhibit chronic degenerative disease through improving of lipid metabolism of lower TG & LDL-cholesterol and higher HDL-cholesterol, and lower AJ.

This experiment was carried out to investigate the effects of the fist harvesting times (vegetative, stem elongation and heading stage) and regrowth periods (20, 30 and 40 days) after the first harvest on dry matter (DM) productivity, crude protein (CP), CP yield and cell wall constituents of gasses during 1987 and 1988. Although the dry matter productivity of grasses at the first was decreased with earlier cutting, the regrowth DM productivity after the first harvest was increased significantly with earlier cutting (p < 0.05). Also the 30 days of regrowth periods was contributed greatly to the DM productivity p <0.05). The percentage of leaf in the leaf: stem ratio was increased with earlier initial harvest and shorter regrowth period after first harvest. The nutritive value of grasses was increased with earlier initial harvest and the 30 days of regrowth period after fist harvest. Based on the results, it is suggested that good grass DM productivity and nutritive value could be achieved by the earlier harvest at first and the regrowth period of 30 days after first harvest in spring.

Using modified Lincoln solution, hydroponic system was developed to compare simultaneously a range of pasture species in terms of relative growth rate(RGR), rate of roots to shoots, and relative root volume and root area. Modified Lincoln solution achieved optimum growth of nineteen forage species tested, and was proved to be a good method for studying plant root characteristics. RGR was measured sucesshlly showing reasonably consistant values over time. There was a much differences in rootkhoot ratio between species within groups as between groups. Root tissue density was lower in grasses than legume or herb group. Root area index was very high for grasses and herbs, and this index should be useful for evaluating the comparative root system of different species.

The objective of this study was to determine the growth characteristics of cool ($C_1$) and warm season grasses ($C_2$) in pastures mixed with $C_1$ and $C_2$ suitable for grazing horses and effect of pastures mixed with tall and short grasses on the intake characteristics of horses. $C_1$ used in this study was Kentucky bluegrass, Redtop (short type grass) and tall type grasses were orchardgrass and tall fescue, respectively. The short type grass used as $C_2$ was Bermudagrass. This study had the following four treatment groups: 1) Treatment 1 (Bermudagrass + Kentucky bluegrass + Redtop) 2) Treatment 2 (Bermudagrass + tall fescue + orchardgrass) 3) Treatment 3 (Kentucky bluegrass + Redtop) 4) Treatment 4 (tall fescue + orchardgrass). There was no winterkilling or lodging problem at an altitude of 200 m. Plant heights in mixed pasture of Treatment 1, 2, 3, and 4 were 53.9, 58.2, 57.5, and 78.1 cm, respectively. Plant height was the highest in Treatment 4. Dry matter yield was in the following order : Treatment 4 > Treatment 3 > Treatment 2 > Treatment 1. In the first investigation regarding vegetation distribution, Bermudagrass ratios among grasses in Treatment 1 and Treatment 2 were 70% and 66.7%, respectively. Overall, other grasses showed poor growth. In the second investigation of vegetation distribution, Bermudagrass ratios among grasses in Treatment 1 and Treatment 2 were 80% and 60.7%, respectively. Crude protein content, neutral detergent fiber content, acid detergent fiber content, digestibility value, and nutritive values were the lowest in Treatment 4, followed by those in Treatment 1, Treatment 2 and Treatment 3.
