AVERAGE YIELD OF MILK AND PER CENT OF FAT OF ALL Cows, 

 ACCORDING TO AGE, WHICH HAVE COMPLETED THEIR LACTATIONS, 

 IN THE AYRSHIRE CATTLE MILK RECORD SOCIETIES UP TO THE 

 END OF 1907. 



A cow yielding 600 gals, at a lactation is said to leave 100 gals, 

 available as profit after paying for food and all expenses; a cow 

 giving 700 gals, could be kept on almost the same food and would 

 give twice as much profit. If this is so and there is every reason 

 to believe that it is with cows which yield 600 to 700 gals, it is 

 not difficult to realise what profits might be reached if cows could 

 be bred to yield 800, 1000 or 1200 gals.
