EXPERIMENT STATION. 



[Jan. 



it is shown that the addition of the blood produced a more rapid 

 and healthy development of the body and tended to increase the 

 proportion of lean meat. 



The Kansas station^ has found a teaspoonfnl of soluble blood 

 flour added to each feeding of milk to be quite efficacious in 

 checking mild cases of scours in calves. 



Ohservations at the Massachusetts Station ivith Blood Meal. 



The station procured a quantity of Armour's blood meal and 

 made the following observations: (1) comi^osition; (2) digest- 

 ibility; (3) its value as a source of protein in place of cotton- 

 seed meal. 



(1) Composition {Per Cent.). 



The small percentage of fiber in the American brand was 

 due evidently to scattered splinters or to sacking. It resembles 

 closely the foreign article, except that the latter contains more 

 fat. Blood meal is the highest grade protein concentrate suit- 

 able for animal feeding. 



(2) Digestibility. 

 The detailed data of this experiment have been already pub- 

 lished.- The blood was fed to two sheep in combination with 

 hay and corn meal. The sheep digested 95.14 per cent, of the 

 dry matter of the blood. The protein appeared to have been less 

 thoroughly digested, namely, 84 per cent. It is probable that 

 the protein digestibility was somewhat depressed by the mcta-
