	abstract = {The present study was carried out in order to measure the effects of  
once daily milking on somatic cell count (SCC) of cows which had either low 
SCS  
or high SCC at the start of the experiment in late lactation.  Thirty six cows  
were used, 18 with low SCC and 18 with higher SCC.  Nine cows from each  
group were randomly allocated to once or twice daily milking for the four week  
experimental period in March.  The yields of milk, fat, protein and lactose were  
significantly reduced by once daily milking (P<0.01) in both groups.  However,  
the effects of once daily milking on yields was larger for high SCC cows  
(interaction P<0.01).  Once daily milking significantly increased the  
concentration of protein (P<0.001) in both groups and fat (P<0.01) in only the  
low SCC group.  Once daily milking significantly reduced the concentration of  
lactose, the effect being larger in the high SCC group (interaction P<0.001).   
SCC (per ml) was increased by once daily milking, but the effect was  
significant only in the high SCC group (interaction P<0.10).  The total number  
of cells produced per day were not affected by once daily milking. 
 
These results show that SCC can be used with confidence to identify  
subclinically infected cows in later lactation milked once or twice a day.  The  
results also show that cows with a low incidence of subclinical mastitis can be  
milked once daily in later lactation, with much less effect on yield of milk and  
its constituents than would be expected in cows with a higher incidence of  
infection. },
