This study was carried out with the aim of understanding the milk production of Friesian X Bunaji cow, their behaviour with regards to grazing time shared with other activities such as walking and standing by means of visual observation. A total of twenty (20) healthy dairy cows comprising of 50:50 Friesian X Bunaji crosses (10 cows) and 75:25 Friesian x Bunaji crosses (10 cows) were used for the study. These crosses were in their second parity. Data were collected for grazing time, walking and standing time, and milk yields. The results obtained showed significant (p˂0.05) differences between the two genotypes in the time spent for grazing and milk yield. Positive phenotypic correlations were obtained and ranged from 0.50 – 0.79 while significant but negative correlation (rp = -0.84) was obtained for walking against grazing. Therefore, it can be concluded that the grazing time be increased for the animals and selection on high milk yielding animals be done using those positively correlated traits as indicators.
