SCIENTIFIC REPORTS OF THE AGRICULTURAL RESEARCH 



the half English blood in the half-bred bull is sufficient to 

 produce the same English characters as regards appearance 

 and build as the full English and it will be of interest to 

 see if this holds good when tested at the pail. 



The double cross-breds are in all points similar to half- 

 breds and do equally well. The first lot of three-quarter- 

 bred crosses which went through the December inoculation 

 had a pretty stiff time which pulled them back a lot; but 

 they are now doing well. 



Experiments with half-bred bulls and country cows are 

 now in progress, and this should enable us to collect data 



which will probably confirm results arrived at with the 



Ayrshire x Montgomery and pure Montgomery cross. 



The undoubted milking powers possessed by Montgomery 



cows being liable to mask any possible improvement in milk 



yield introduced by half-bred bulls which would probably 



show clearly in stock got from an ordinary country cow of 



a poor milking breed. 



The full lactation yields for the six half-bred cows 



from Mossgeil Titanic were as follows and fully bear out 



the remarks made about them in last year's report : —

The yield of the last two cows was considerably 

 reduced, by udder trouble in the first case while Biddy is 

 shy of a teat. 



These cows have now calved again and are, with the 

 exception of the last two noted above, milking excellently. 



Six Lessnessock Wildfire heifers have calved and are 

 now giving an average of 18-20 lb. per day. 



One Carston Royal Scotch heifer calved on 7th March, 

 1919, and is now milking well. The remarkable evenness 

 of yield shown by all these heifers whether got from cows
