Description

<p>Digitgrass Transvala （TR） hay was estimated the dry matter intake （DMI） and crude protein intake （CPI） by breeding Japanese black cattle comparing with Oat hay. The feeding ratio of TR or Oat hay was 50％ in a total feeding amount. The DMIs of TR and Oat hay were 3.63±0.17 kg DM /day and 3.66±0.09 kg DM /day respectively. The CPI of TR hay （0.23±0.01 kg DM /day） was significant higher （P < 0.01） that of an Oat hay （0.17±0.00 kg DM /day）. The fluctuation of body weight, withers height and chest girth in breeding Japanese Black cows were no significant difference between TR and Oat hay. These results showed that TR hay was satisfactorily to use as the basal diet for breeding Japanese Black cows.</p>
