Abstract

フリーストール飼養1農場 (24頭) および繋ぎ飼養3農場 (38頭) のホルスタイン種搾乳牛を農家ごとに産次と分娩月を一致させた2頭を1組として2群に分け, 一方を削蹄群として分娩前1~2カ月および分娩後4~5カ月に四肢蹄の削蹄を行い, 他方を非削蹄群として無処置とした. フリーストール飼養牛の削蹄群および非削蹄群の各2頭に蹄病が発生したが, 他の疾病の発生はなかった. 削蹄群と非削蹄群の1乳期の泌乳量はフリーストール飼養牛 (それぞれ6, 935および6, 456kg) および繋ぎ飼養牛 (10, 331および10, 095kg) のいずれも削蹄群で多かったが, 有意差は認められなかった. いずれの農場もよい飼養管理環境であったので削蹄による快適性や生理的泌乳能力の増加がもたらされなかったことがその理由と考えられた.

Twenty-four Holstein cows housed in cubicles on one farm and 38 cows housed in three-tie stall on another were divided into 2 groups (P and NP) according to matching parity and calving month. The hoofs of the cows in group P were trimmed from 1 to 2 months before and from 4 to 5 months after calving. The hooves of the cows in group NP went untrimmed. Per-lactation milk production of the two groups was compared for animals accommodated in both housing systems. Among animals housed in cubicles, foot disease appeared in two animals in each group. Otherwise no foot diseases developed throughout the experimental period. Although animals in group P produced more milk than those in group NP (cubicle-housed P: 6, 935 and NP: 6, 456 kg; tiestall housed P: 10, 331 and NP: 10, 095 kg), the differences were not significant. Perhaps the comfort and psychological impact of hoof trimming had no effect on milk production because management conditions at both farms were good.
