Two Japanese black breed (one 7 1/2 year-old cow and one 14 month-old steer) and two shorthorn grade (both 26 month-old) were fed fattening rations for 158 days (Japanese black breed) and 141 days (shorthorn grade). The fattening rations consisted of grass or hay, potatoes and dried beet pulp, and concentrates mixture, in proportion of about 1 : 0. 2 : 0.8 (1st period), 1 : 0.5 : 1.4 (2nd period) and 1 : 1.75 : 2 (3rd and 4th period), in airdried basis. Results are as follows : [table] In all 4 cattle, fairly good fattening results were obtained. In the shorthorn grade, more daily gain, lower feed coats per unit of gain and lower dressing yield than in the Japanese black breed were notable.
