During the experimental period, the average total milk yield in JB, JS, and HS cows was 486.0kg, 1,724.0kg and 4,859.2kg, respectively. JB and JS cows had peak lactation at 2-3 wk PP, whereas in HS cows daily milk yield reached a peak at 7-8wk PP. In milk contents of colostrum, little differences in milk fat (%) were observed among the breeds. Regardless of breeds, the colostrum on parturition day was composed of higher milk protein (%) and lower lactose (%), as compared with the milk composition thereafter. After 2 wk PP, milk fat significantly differed among the breeds : JB>JS>HS. After 8 days PP, the change in milk protein was similar to the trend in milk fat. No significant differences in lactose were found between JB and JS cows. These beef cows tended to have higher lactose than HS cows till 10 wk PP, thereafter there were no differences in lactose among the breeds. These results suggest that JB and JS cows have peaks of milk production at earlier stages of lactation than HS cows, and that milk composition differs among the breeds as lactation progressed.

分娩日から後6ヶ月 (26週) に至る乳量, 乳成分の変化を調査した。分娩後6ヶ月間の黒毛和種, 日本短角種及びホルスタイン種雌牛の機械搾乳による平均総乳量は, それぞれ486.Okg, 1, 724.Okg, 4, 859.2㎏であった。泌乳ピークは黒毛和種及び日本短角種とも分娩後2－3週にみられ, 前者は10週以降, 後者はピーク到達後漸減した。一方, ホルスタイン種の泌乳ピークは分娩後7－8週に認められた。初乳中の乳脂肪率は品種間で大きな違いは認められなかった。分娩日の乳蛋白質率は分娩日以降の乳蛋白質率に比べて極めて高くなったが, 乳糖率は逆に低くなり, これら結果は全ての品種で認められた。常乳の乳脂肪率は分娩後2週以降黒毛和種, 日本短角種, ホルスタイン種の順に低くなった。乳蛋白質率は分娩後8日以降乳脂肪率と同様な傾向を示した。乳糖率の変化は黒毛和種, 日本短角種で類似し, 分娩後10週までホルスタイン種よりも高くなる傾向が認められたが, それ以降は品種による違いはみられなかった。以上の結果から, 黒毛和種及び日本短角種ではホルスタイン種よりも早く泌乳ピークに到達すること, 泌乳期の進行に伴う乳成分の変化は品種間で異なることが明らかとなった。\n","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24514/00001155","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"独立行政法人
