Balance in favour of October Calver .,825 



These estimated results appear to show that the 

 balances to be obtained by winter milk production as 

 compared with milk produced mostly during the 

 summer months of the year, are approximately the 

 same. In arriving at these results, it has been assumed 

 that a spring calver gives the same amount of milk as 

 an autumn calver, but is this so ? The following results 

 will shed light on this point. 



In some trials carried out by the Irish Department of 

 Agriculture, Mr Adams gives the following interesting 

 comparisons of November and April calvers. There 

 were five cows in each lot, records being kept in the 

 case of the November calver for the twelve months, 

 Nov. 1907 to Nov. 1908. In the same way the records 

 of April calvers were kept from April 1908 to April 

 1909. A few results selected from the report are as 

 follows :
