Two grazing systems-continuous and rotational-were compared on herbage utility and body weight gain in a timothy parture at the Taekwanryung area by the 13 Korean native heifer from 1978 to 1979. The results obtained were summarized as follows: 1. In dry matter yield per ha, non significant differences (P$gt;0.05) was found between two systems, however, the rotational grazing tended to be clearly increased compared to continuous grazing. 2. In total haerbage consumption per ha, the rotational grazing was significantly increased by 17% (P$gt;0. 05) compared to continuous grazing, whereas, and average herbage consumption per head, per day was highered in continuous grazing. 3. In utilization ratio of herbage, the rotational grazing was increased by 8.4 compared to continuous grazing. 4. In liveweight gain per ha, the rotational grazing was significantly increased by 13% (P$lt;0.05) compared to continuous grazing, whereas, the liveweight gain per hear, per day was slightly increased in continuous grazing. 5. In sward composition of ladino clover in timothy pasture, the continuous grazing was slightly increased than rotational grazing and also it tended to be increasing as grazing year advanced.

Seasonal changes in chemical composition. in vitro dry matter digestibilitv(IVDMD), dry matter(DM) yields and DM intake of browse(leaves of trees and shrubs) by four sika deer(Cervus nippon) bucks were studied from 1988 to 1989 under deforested slope mountain in northern part of Korea. the contents of moisture, crude protein(CP), crude fiber(CF), neutral detergent fiber(NDF) and IVDMD of mixed browse were 54.1-61.0%, 17.0-19.0%, 48.7-56.0%, and 52.3-64.6% on a dry matter basis, respectively. The contents of moisture, CP and IVDMD of mixed browse were decreased, while CF and NDF were increased as the season progressed. Robinta pseudo-acacia generally had high levels of CP and Pinus densiflora had a high levels of CF and NDF, but Pueraria thunbergiana had high levela, of IVDMD in all browse species. the leaves of Iegumes had higher levels of CP and IVDMD but lower levels of CF and NDF than other browse species. T he DM yields of mixed browse per ha was 1,607,0kg. The DM intake of browse per head and per metabolic body size were 1,252.68g, 50.03g in spring, 1,264.3g, 47.71g in summer, and 1,115.7g, 44.90g in autumn, respectively.

Distillers sweet potato and naked barley were studied for analyzing the chemical nutrients and measuring the metabolizable energy using chicks. Test materials were obtained 1) by sieve or filter press (7, 100 or 250 mesh) from distillers waste solution, and 2) by ground surface where the distillers waste solution were damped and part of liquid portion was leached down. The test materials were used in chemical analysis and metabolic energy test after dried in a draft oven at 60-70℃. Approximate analysis were conducted by the A.O.A.C. method. The cations were determined by the atomic absorption method and phosphorus was measured by colorimetry. Metabolizable energy content was observed by indicator method using the commercia diet which was replaced by the distillers sweet potato (40%). The crude protein contents of distillers sweet potato were 12.23% at air dry basis and those were increased as the finer sieves were used. No big differences were noticed on the contents of ether extract and ash. However, nitrogen-free extract increased and crude fiber decreased as the mesh of sieve or filter press increased. The changing trend of proximate analysis in distillers naked barley was similar to that in distillers sweet potato. However, the contents of crude protein, ether extract and nitrogen-free extract in distillers naked barley were higher and those of crude fiber and ash were lower than in distillers sweet potato. The high content of iron in distillers solids were noticed especially. It was thought that the reason might be drived from many steel facilities in distillers factory. The metabolizable energy content in distillers sweet potato from 100 mesh sieve was 2,250 ㎉/g and it was higher than those in some brans and similar to those in some seed meals.

A study was conducted to determine the herbage productivity and availability upon the flat, slope and forest type of grassland using Korean native cattle and sheep under 4 year old grassland established by intensive and semi-intensive sowing methods in Daecheon, from 1987 to 1988. The results obtained are summarized as follows ; 1. Orchardgrass made up the major plant species of the diets on all grassland types, especially the proportion of orchardgrass was 81-92% of the diets on the forest grassland. The proportions of tall fescue and ladino clover of the diets slightly increased on the flat and slope grassland in summer(July and August). Plant height and leaf area indes (LAI) on the flat, slope and forest grassland were 23.9cm-3.46, 23.1 cm-3.27 and 21.3cm-2.91 in average, respectively. Total dry matter(DM) yield per ha on the flat, slope and forest grassland was 10,286kg, 9,563kg and 6,341kg, respectively. The seasonal distribution of DM yield on all grassland types was 64∼70% in spring (April, May and June). Crop growth rate (CGR) on the flat, slope and forest grassland were 44.4kg, 41.4kg and 27.3kg, respectively. 2. Contents of crude protein (CP) and in vitro DM digestibility(IVDMD) of collected herbage samples were high in spring, while contents of crude fiber(CF) and neutral detergent fiber(NDF) were high in summer on all grassland types. The order of the contents of CP and IVDMD was flat$gt;slope$gt;forest grassland. The DM and organic matter(OM) intake per unit metabolic body size(g/w^75kg) were high on the flat, grassland, but those on the forest grassland, were low, digestible DM intake(DDMI) and DOMI showed a same tendency. Significantly positive correlations was found between DMI and CP(p$lt;0.05), and IVDMD(p$lt;0.01), but significantly negative correlation(p$lt;0.05) was found between DMI and NDF on all grassland types. The order of the DMI was spring$gt;summer$gt;autumn. 3. The percentage of herbage utilization on the flat, slope and forest grassland was 76.2%, 75.2% and 74.8%, respectively. The order of diet preference based on the relative intake index(RII) and touch number was flat$gt;slope$gt;forest grassland. Grazing capacity on the flat, slope and forest grassland was 542,496 and 323 cow-day/ha in average, respectively. The calculated value of grazing area per cattle(AU) on the flat, slope and forest grassland was 0.67ha, 0.74ha and 1.13ha, respectively. 4. Grazing and ruminating time were not different among the grassland types, but those were slightly increased on the forest grassland. Resting and loafing time were slightly increased on the flat grassland. Walking time was increased on the slope grassland. The number of rumination, chews per bolus and urination were slightly increased on the forest grassland, but defecation number was increased on the flat grassland. The number of drinks, total drinking water consumption and walking distance were slightly increased on the slope grassland. 5. Animal distance and occupied area per cattle on the flat, slope and forest grassland were 4.34m-11.7㎡, 3.97m-12.6㎡ and 3.76m-16.8㎡, respectively. Subgroup formation on those grassland was 3.9head, 4.4 head and 4.2 head per group respectively. The order of grazing movement was similar to the pear-shaped grazing formation, but the relation of dominance between first grazer and last grazer upon different grassland types was not clear. 6. Eating, ruminating and chewing time on the flat grassland were slightly less than on the other grassland. The order of eating rate, ruminating and chewing efficiency was flat) slope) forest grassland. 7. Live weight gain per day on the flat, slope and forest grassland during the grazing and feeding was 0.586-0.923kg, 0.565-0.882kg and 0.470-0.826kg, respectively. The order of feed efficiency was flat$gt; slope$gt;forest$gt;grassland. 8. The cost value of grasses per ha which was not included the rent was 650.1 thousand won on the flat, 650.1 thousand won on the slope and 5

In order to investigate the food habits of the sika deer, 21 spring, summer and autumn browse(leaves of trees and shrubs) species in northern part of Korea were evaluated by using four sika deer(Cervus nippon) bucks from 1988 to 1989. The most frequently chosen food item in all browse species sampled during spring, summer and autumn were Pueraria thunbergiana, Quercus dentata and Lespedeza spp. respectively. Prunus sargentii, Robinia pseudo-acacia, Morus bombycis. Castanea crenata, Quercus serrata, Ampelopsis brevipedunculata, Corylus heterophylla and Acer-pseudo sieboldianum were also the important browse species and frequently eaten by sika deer throughout the season, but the selection and preference ranking of browse species differed by season. Sika deer diets consisted of 61.3% browse, 29.7% forbs and 9.0% grasses in average. Three daily peaks of eating time were noted.
