Evaluation of Similarity in Growth and Carcass Characteristics of Somatic Cell d Beef Cattle Shinichi YAMADA, Atsushi NISHIYAMA, Tadashi KAWAMURA, Yuji GOTO, Toshihiro NADE, Toshiaki OKUMURA and Kenji YAMAUCHI National Livestock Breeding Center Tokachi Station, Otofuke-cho, Hokkaido *2**/1,, Japan National Livestock Breeding Center, Nishigo-mura, Fukushima-ken 302/, Japan Corresponding : Shinichi YAMADA (fax : 2 (*) //..,,/, e-mail : s*yamada@nlbc.go.jp) Somatic cell cloned cattle of Japanese Black were fattened under the same condition, and similarity in growth and carcass characteristics were examined. Four somatic cell cloned steers and two somatic cell cloned heifers which were born at almost the same period were fattened according to similar fattening method of the donor. The clones of respective groups were compared with one another and with their donor on growth, feed intake, carcass characteristics and the physiological chemistry analysis of the M. longissimus thoracis. In each item, high similarity was recognized in the cloned steer, while di#erences in growth and meat quantity traits were recognized in the cloned heifer due to illness. Between the clones and the donor, there was an environmental factor by the di#erence in fattened time and place which caused the di#erence in the growth. On the other hand, similarity was suggested in BMS No. and ether extract of M. longissimus thoracis. High similarity was recognized among fattened somatic cell clones, although growth and meat quality traits might be a#ected by the condition of the clones. Nihon Chikusan Gakkaiho, 1/ (,) :0/11,,**.
