To investigate the condition of improved grassland after 2-15 years establishment, six co-operative village farms were surveyed during Spring, Summer and Autumn. The results obtained were as follows. 1. The average daily weight gain of cross bred cattle was investigated and gains were found to be closely related to pasture yields. Yield declined as pastures got older. 2. Despite it being 15 years older, Ohra grassland, because of correct annual fertilizer application, compared favoriously with other farms. 3. The average botanical composition of the selected six farms was; 16% grass (tall fescue, orchardgrass, and ryegrass.), 9% legume (ladino clover), and 24% others (native grasses and weeds). Haweon farm after 2-5 years establishment had a weed composition of 8% compared with an average of 25% for other farms. 4. The chemical composition of surveyed improved pasture was 19.25% crude protein, 13.38% crude fiber, 8.85% Ash and 2.88% ether extract. 5. The percentage crude protein decreased as season advanced as follows: Spring 26.03%, summer 17.62% and Autumn; 14.4%. There was also a significant relationship between crude protein and daily weight gain.

제주한우의 사양관리와 번식상황이 격년분만에 미치는 영향 3 . 제주한우의 사료급여 수준이 번식상황에 미치는 영향

This investigation was conducted to find the effect of different levels of supplementary feeding on reproductive performance and calving disorders. Six hundred Cheju native and Cheju crossbred cows were divided into three groups (A, B and C) and fed different levels of supplementary feed. 1. The age of first insemination of heifer in group A (fed over 1 ㎏/day of various brans) was 2-7 months earlier than those of group B (less than 1 ㎏/day of various brans) and group C (hay only). 2. The first calving age in groups (A and B) was 6-7 months earlier than cows in group C. 3. The calving interval in groups A and B was reduced by 3 months and the recurence of estrus after parturition was 20 days earlier than cows in group C. There was, however, no significant difference in estrus cycle and gestation period when cows were fed different nutritional levels.

舍飼期間中 濟州韓牛의 飼料給與狀態가 體重變化, 繁殖狀況 및 隔年分娩牛에 미치는 影響을 調査하기 爲하여 濟州道內 六個部落에서 飼育되고 있는 供試畜 400餘頭를 調査한 結果는 다음과 같다. 冬期間 飼料給與狀態에서는 各部落別 큰 差異는 없었고 補充飼料를 1kg以上 給與하는 戶數는 全體의 4.8%로 매우 낮았으며 糠類飼料(單用)을 每日 若干씩 주고 있는 農家는 46.6%로 過去보다 增加르 보였으나 乾草만으로 飼育하는 農家는 48.6%로서 漸次減少 現象을 보이고 있다. 冬期間 月別體重變化는 大部分 一月에서 四月까지는 大體로 20∼30kg 減少 趨勢를 보이다가 放牧場에 入殖된 五月에는 約 10∼20kg 增加되는 傾向을 보였으며 濟州韓牛와 交雜種間의 比較에서는 Brahman 交雜種이 體重變化가 가장 적은 反面 韓牛와 Santa 交雜種은 體重 減少幅이 極甚하였다. 未經産牛에서 初分娩月齡은 가장 빠른 地域이 38.2個月이 었고 늦은 地域은 40.5個月로 2個月差異가 있었으며 經産牛의 分娩後 初發情 再歸日에에서 隔年分娩牛를 除外했을 때는 平均 90.4日이고 地域別 10-20日差가 있었는데 反하여 隔年分娩牛를 包含시켰을때에는 平均 174.2日로 상당히 길었으며 地域別 差異도 甚하였음을 보여 주었다. 隔年 分娩牛의 發生率은 地域別로 볼 때 平均 13%에서 23%의 差異를 나타내고 있었으나 年度別로 比較할 때는 1980年度 9.5%, 1981年度 33.5%, 1982年度 11.9%로 隔差가 甚하였다. To investigate the effect of giving different feeds, during the winter, on body weight changes, reproductive performence and alternate year calving cows. 400 Jeju native and cross bred cows and heifers housed in villages were studied. Results showed no appreciable difference amongst the 6 villages feeding different foods during the winter period. Percentage of farms feeding various brans, over 1kg per day, was 4.8% ; a small quantity(0.5kg) of various brans was fed daily to 46.6% and those feeding only natural hay, 48.6%. The number of villages feeding various brans is increasing and those feeding hay decreasing. Cattle weights decreased by 20-30kg monthly per head during the winter feeding period(January-April) but by May increased in the range of 10-20kg per head with arrival of the new grass. Comparison of monthly body weight changes of Jeiu native cows and cross breds, Brahman cross breds showed the least body weight changes during winter while Native and Santa cross bred cows the weight changes were considerable. The average age at first calving, in the regional groups, varied by two months and when averaged out was 38.2 and 40.5 months in the early and late regions respectively. There was an average of 90.4 days from calving to first estrus excluding alternative year calving cows which had an avarage of 174.2 days from calving to first estrus. The alternate year calving percentages averaged from 13% to 23% in regional groups, and were 9.5% in 1980, 33.5% in 1981 and 11.9% in 1982.

濟州地域 部落共同 牧場의 草地狀態 및 氣象現況이 飼育中인 家畜의 增體에 미치는 영향을 究明하기 위해 6個部落 共同牧場(영남,해안,회천,용강,오라,하원)에서 成牝年 415두의 體重과 그 牧場의 草地狀態를 調査한 結果는 다음과 같다. 1. 試驗이 實施되는 部落共同牧場의 草地面積 197.8ha중 改良草地比率은 66%이며 頭當面積은 0.9ha였다. 2. 名 牧場 共히 牧草 보다 野草의 乾物收量이 높으며 2回 收穫 中 牧草는 初期收量(1734㎏/ha>1459㎏/ha)이 높았고 野草는 後期收量이 (2025kg/ha<4734kg/ha)높았다. 3. 野草의 粗蛋白質 含量은 施肥草地(12.05%)가 無肥草地(7.87%) 보다 높았으나 牧草는 施肥에 關係없이 비슷한 傾向이였으며 粗纖維含量은 無肥草地가 높았다. 4. 月平均 增體量은 6月 347.0kg, 7月 358.5kg, 8月 384.5kg, 9月 414.2kg, 10月 421.8kg로서 放牧期間中 頭當 總 增體量은 74.8kg이며 月別 1日 增體幅은 9月에 頭當 1.05㎏으로서 本 試驗期間中에 가장 크다. 5. 日當 平均 增體量은 하원 0.89kg, 해안 0.81kg 영남 0.71kg, 회천 0.60kg, 용강 0.58kg과 오라 0.15kg 順位였으며 全體平均 日當增體量은 0.61kg이였다. The study was carried out to investigate the effect of grass quality and climate on weight gain. Six co-operative village farms were surveged which reared Korean native and Korean cross-bred cows. The results obtained were as follows; 1. The farms examined had 66% improved pasture and a stocking rate of 0.9ha per head. 2. On all the farms, the total dry matter content of native pasture was more than that of the improved pasture. 3. In the case of native pasture the crude protein content when fertilized(12.05% cp compared to 7.87%). On the other hand, there was no difference in crude protein content between fertilized improved pasture and non-fertilized. The crude fibre content of improved and unimproved pasture decreases when fertilized. 4. Body weights during June, July, August, September and October were 347.0kg, 358.5kg, 384.5kg, 414.2kg and 421.8kg respectively. 5. The average daily weight gain on each farm was 0.89kg on Hawoen, 0.81kg on Yeong Nam, 0.71kg on Hoicheon, 0.60kg on Young Kang and 0.15kg on Oh Ra: The total weight gain of all the cows on all the farms was 76.8kg with an average daily weight gain of 0.6kg per cow.
