accuracy, samples be drawn during four successive days at any time between 

 the third and eighth months (inclusive) after the cow has calved. Should 

 disturbing factors supervene, samples should be drawn and tested for six 

 consecutive days. No samples should, however, be taken for six weeks after 

 the cows go on to the pasture from the house, nor during the first three 

 weeks after the cows have come into the house from the pasture. The 

 result is more reliable if the period of sampling be limited ; and when this 

 is confined to the fifth and sixth months of the lactation period, the possibility 

 of error is reduced to a minimum.
