        Ths study was carried out to investigate the profitability for livestock farming in Cheju Island. Farm types of Breed were breeding cow, beef cow, dairy cow, layer and broiler farming. Annual gross receipts per farm were 77,903, 30,023, 28,482, 16,041, 3,998 and 2.510 thousand won for the beef cow, hog, dairy, broiler, breeding cow and layer farming in order, respectively. Net incomes per farm were 56,823, 13,969 and 664 thousand won for the beef cow, hog and broiler farming in order, respectively. But for the breeding cow, dairy and layer farm suffered a loss in net income. Annual gross receipts per animal head were 421,000, 1,166,000, 890,000, 43,000, 642, and 355 won for the breeding cow, beef cattle, dairy, hog, layer, and broiler, respectively. Net incomes per animal head were 851,000, 20,000 and 15 won for the beef cattle, hog, broiler farming, respectively, but breeding cow, dairy and layer farm showed a loss in net income. As a whole it is suggested that the fitness of animal size over the utilities invested should be reappriased by farming type and that raising management levels and the items of cost and in-come be also reviewed for the reasonable mamaging, especialy in the breeding cow, dairy and layer farm.

      • 제주지역 우유생산의 효율성 분석

        강태숙 제주대학교 농과대학 제주도축산문제연구소 1989 畜産論叢 Vol.4 No.1

        From a policy point of view, con -arisons of actual individual produation and cost estimates with individual dairy farmers' best production and minimum cost provide useful insights into the farm level production technology. The objective of this study is (i) to imstigate farm level economic performance in Cheju area milk production, (ii) to examine what mnagement factors simificantly affect technical and allmtive efficiencies, and (iii) to make camparisom of emunic efficiency anorg Kyungki, Chungcheong, and Cheju regions. The cross section milk production and related price records were collected during the 1985 production year. The samples consist of 72 dairy farm from the three regions : 33 from Cheju, 20 from Kyungki, and 19 from Chungcheong area. A Cobb-Douglas ( C- D ) frontier production functicn was specified in term of the number of cows, concentrate, roughage, and labor hours, and it ws estimated by Fletcher - Powell-David non - linear optimization algorithm. The dual cost function was numerically de-rived, using the producation function parameter estimates. The technical efficiency indices of Cheju dairy farms ranged from 0.6523 to 0.7207 with mean 0.6925, while the allocative efficiency showed a range of 0.4231-4.6113 with man 0.4796. The quantifiable management factors which can affect farm- level economic efficiency were age, education. and dairy farming experience. Of this, manager's dairy experience was the most important variable which had sieificantly psitive effect on higer tecfnical efficiency. In terms of regional comparisas of technical and allocative efficiencies Cheju had no significant differentials amom the three areas. Only there exists a little difference in technical as well as allocative efficiencies beetween Cheju and Churgchmg areas. The above suggests (i) that, in order to improve the overall dairy economic efficiency in Cheju, more integrated extension program should be created for the dairy farms below average technial and allocative efficiemies,under the local goverment initiatives,and (ii) that, since manager's dairy experience in the most important factor which can affect technical effiaency, dairy experience should be the first consideration of the dairy development polices.

        강태숙,김동철 제주대학교 농과대학 제주도축산문제연구소 1986 畜産論叢 Vol.1 No.1

        Studies were carried out on 60 imported beef cattle to investigate the relationship between carcass weights and selling prices of Angus, Charolais, Hereford, Angus × Hereford, charolais × Hereford and Charolais × Angus. 1. The average live weight of Charolais (476.5kg) before slaughter was considerably heavier than any other pure breeds. In crossbreds the live weight, before slaughter, of Charolais × Angus(497.1 kg) was heavier than any other crosses. There were significant differences at 1% level betwpen breeds. 2. The greater the live weight was the heavier thecarcass (P< 0.01) but no statistical significant difference were found between dressing out percentage of different breeds. 3. There was m significant difference in average carcass unit price(6,129.9±26.5 won) between breeds. However there was significant differences at 5 % level between the two abattoirs. 4. Carcass selling price between breeds was highly significant but there was no differences in selling price between abattoirs. The selling price of by-products was not significantly different between breeds but was highly significant between abattoirs. 5. The total selling price rose as the live weight of different breeds and carcass unit price increased but there were slight differences between the two abattoirs investigated. 6. The carcass unit price was not related live and carcass weight, however, there was no correlations coefficient between carcass unit price and live or carcass weight. 7. Carcass selling price and total selling price were correlated in the treatments but the by-products selling price bore no correlation to carcass perccctage and carcass unit price.

This survey was carried out to analyze the dairy farm management and structure on 25 dairy farms in Juju Do. The results of economical analysis are as follows. 1. The total number of dairy cattle was 417 which consisted of 291 cows. (250 milking cows, 41 dry cows and 126 follows.) The average livestock unit per farm was 13.41 L.U. 2. The average forage crop area per farm was 3.56 ha (0.31 ha/head). Average forage crop area plus pasture per head was 1.28 ha. 3. Cattle shelter per farm was 185.1㎡ (15.9㎡ per cow) ; storage was 139.2㎡ (3.3㎡per cow) and silo was 6.7 ?/? per cow. 4. The annual investment per cow was 6,770 thousand won, in the proportion of 55.9% land, 23.8% dairy cow ; 9.1% building ; 6.8% recurrent and 4.3% equipment. 5. Average milk production cost per cow was 1,677,346 won, 71.9% (1,205,694 won) was operational expenditure and feeding cost amounting to 37.0% of the total cost. 6.

      • 제주낙농업의 현황과 문제점

        강태숙,김창섭 제주대학교 농과대학 제주도축산문제연구소 1987 畜産論叢 Vol.2 No.1

        The present study was conducted to analyze the present condition and fundamentals of dairy farming, and to offer proper imformation to Cheju dairy farmers and authorities concerned in order t o develop the dairy business in Cheju province. The percentage of cattle kept in Chelu province was 1.9 compared to those of the nation as whole: however, the percentage of dairy cattle was 0.5. This indicates that Cheju dairy farmlng is behind other provinces in its development. Keeping dairy cattle was more profitable than keeping other domestic animals, and the milk supply is short of the demand in Cheju province. Therefore. it is considered desirable to increase dairy cattle kept in Cheju province. The number of dairy cattle imported from foreign countries was 1,536, and 420. from the mainland. The dairy cattle imported were from Japan, Australia and America. The average number of dairy cattle per household was 14.2 in cow units, and number of cows, 12.3. The percentage of cows was somewhat high. 86.8%. The number of calves, heifers and bred heifers was smaller as the herd size became smaller. The average farm was 39,898 pyeong in area. Among them, rented area occupied 7.953 pyeongor 20%. The average farmland per head was 2,738 pyeong. Among them, fodder fields and cultivated pasture occupied 938 pyeong and 1.508 pyeong, respectively. Shelters secured per head averaged 3.95 pyeong. and silos 6.8 M/T. There were no significant differ-ences observed between herd sizes. The average labor-hour per head was 369.5, and the group of less than 10 head showed the most hours, 475.8. The percentage of self-supplying labor was 51.5. As the herd size became larger the labor-hours per head trended to become less.

        For the improvement of livestock farming in Cheju province, to study the management of the uillage cooperative ranches, A survey on 30 full time cattle farms and 10 side job cattle farms were carried out for one month. The results analysed areas follows: 1.The pasture area of the 30 cooperative ranches was 8.3% of the total pasture area in Cheju. However, those 30 cooperative ranches wet·e raising 22% of the total number of all the cattle in Cheju. 2.The pasture area of the total cooperativeranches in Cheju was 35% of the total pasture area and the village cooperative ranches had 60% of the total Ri in Cheju. 3.The average size of the cooperative ranches was 163 ha and pasture area per head was 0.4ha, and per farm was 1 ha. Cattle raising farms was 67% of the total farms and the average herd size per farm was 2.5. 4.The number of beef Cattle in Cheju was 72% of Korea and the area of the improved range in Cheju was 40% of the total area in Korea. 5.Foully four percent of the feeding bull was Brahmans and 74% of those seeking the service of bulls premiered Brahmans. 6.Twenty six percent of the cooperative ranches had silos in their respective vilages, but only 5.3% of raising cattle household in the village that had silos used them to store silage. 7.Eighty five percent of the farms wanted to put fire on their pastures. Their main reason is to graze early and to control tick problem.

      • 酪農經營에 있어서 新規와 旣存酪農農家의 經營成果에 關한 分析

        This study was conducted to analyze the actual condition and the management results of 291 cows on 25 dairy farms of which 14 ( advanced farms ) were established more than three years ago and 11 (new farms) were built up within three years from now. The results obtained were as follows; 1. The average cow numbers per the new dairy farm were 7.8 and the average heads per the advanced farm were 14.6. The average livestock unit of the new and the advanced farm were 8.4 and 17.3 respectively. 2. The size of land for forage crops, pasture and natural pasture was 1.51 ha per cow of the new farm and 1.68 ha per cow of the advanced farm. 3. The new dairy farm had an average size of 15.8㎡ for the cattle shelter and 23.14㎡ for the storage room while the advanced farm 15.8㎡ for the cattle shelter and 32.17㎡ for the storage room. 4. The annual labor days per dairy farm were 668 and the daily working time was found to be 9.7 hour. The annual labor time consumed for a cow were 422 hours of which 210 hours were from the family labor and 212 hours from the hired labor. 5. The new farm put ₩6,312,000 of the dairy investment per cow, the total investment being w49,351,000. On the other hand the advanced farm laid out ₩6,962,000 of the dairy investment per cow, the total investment being ₩101,957,000 and twice higher than the new farm's capital investment. 6. The new farm made ₩1,671,000 of the annual gross receipts per cow which was equivalent to ₩13,066,000 of the total gross receipts per household while the advanced farm got ₩1,977,000 of the annual gross receipts per cow ₩28,962,000 of the total gross receipts per household. 7. The feed cost occupied 51.9% of the total expenditure and the depreciation 11.7% in the new farm. Similarly the advanced farm paid 51.2% of the total cost for the new feed and 11.1% for the depreciation. The percentage of hired labor cost was 5.1 on the new farm but 11.8 on the advanced farm 8. The cost of milk production per kg was less than ₩200 when the milk yield per cow was highest and labor cost lowest. Most of the new farm, 36% of the total farms surveyed, spent more than ₩301 to produce one kg of milk and gave the lowest milk production. 9. The total annual income of the new farm about ₩3,918,000 which meant ₩308,000 of the annual income per cow. The advanced farm, however, could obtain ₩11,089,000 of the total annual income and ₩757,000 of the annual income per cow. The results indicated that the new dairy farm showed a deficit of ₩25,000 per cow and consequently a tatal deficit of ₩202,000 annualy while the advanced farm obtained a net return of 308,000 per cow and a tatal net return of ₩4,523,000 per household.
