Abstract
To promote utilization of Jersey cow's meat, we investigated the feeding situation and the ment producing characteristics of the Jersey breed in Hiruzen province. The results obtained were as follows: (1) Jersey meat is processed and sold by hiruzen Dairy Co-operation Association at Hiruzen. Most of the meat is occupied from steers, and cow meat comprises only 10%. (2) Fattening-feed performance was observed on non-delivered cows and delivered ones which were less than 5 years old. Dressing yield of the non-delivered cows was higher than that of delivered ones. (3) A linear correlation between body and carcass weight was found. Therefore, it was recommended that large cow production would bring profits in terms of economic gain. (4) The fat contents of longissimus muscle of the Jersey breed were higher than those of Holsteins, so it was considered they would probably have high marbling characteristics.

ジャージー種雌牛の食肉利用を推進する観点から、蒜山地域で行われている利用の状況ならびに食肉資源としての特性について検討した。その結果は次のとおりである。(1)蒜山酪農農業協同組合で飼育されているジャージー種のうち、酪農組合で食肉として処理、販売されるのは主としてさく去勢牛で、雌牛については1割程度しか利用されていなかった。(2)未経産牛と5歳齢以下の経産牛では、肥育飼養されていると推察された。(3)出荷体重と枝肉重の間に正の相関関係が認められ、出荷体重が大きいほど産肉牛が多かった。(4)ジャージー種はホルスタイン種よりも胸最長筋の脂肪含量が高く、脂肪交雑の入りやすい特性があると推察された。
