In these ex])eriineut& again 

 results have been obtained in feeding separated milk and fat substitutes. 



Each lot of calves also received linseed cake as soon as they would 

 eat it, in small quantities at first, but gradually increas.d, so that at 

 the time of weaning they had 1 lb. per head daily. 



The Deipartment of Agriculture for Ireland were so satisfied 

 with the results of feeding with this meal that they now recommend 

 it to Irish farmers as a standard milk-fat substitute. 



The following experimental results were obtained by the N.E. of 

 Scotland Agricultural College at Aberdeen from 1908-1911, with 

 three series of experiments on forty-four calves in all, divided into three 

 lots. The object here being to compare the value of cotton seed oil 

 with cod liver oil, as the latter has very much increased in price, while 

 the former was obtained at 2s. 7d. per gallon.
