EXPERHIENTAL FARMS 



5 GEORGE v., A. 1915 



The results show a slightly increased production during the period in which was 

 fed Molascuit as compared with the average of the two Molassine meal periods. 

 ]\[ola3Cuit being lower in cost than Molassine, the cost of production for period -t is 

 still further lowered.

Here the results are in favour of the Caldwell's molasses meal, milk production 

 being slightly higher, and cost to produce lessened accordingly, the lower price of the 

 latter meal still further reducing the cost. 



SUMM.ARY. 



The feeding periods with the meal mixture pltis Molascuit, meal mixture plus 

 Caldwell's molasses meal, and meal mixture less molasses, all show increased produc- 

 tion over the average of a preceding and following Molassine meal feeding period. 

 The lower price of the three former meal mixtures, combined with the above fact,, 

 quite appreciably lessens the cost to produce. 



COMPARING MOLASSES MEALS FROM A CALDWELL S MEAL STANDARD. 



At the expiration of the foregoing experiment, the test was continued on the 

 above indicated basis. A number of high-cla.ss Holstein and Ayrshire grades having 

 been purchased, and several individuals of the herd having freshened, eleven cows 

 were available, all at a stage of lactation where production wotild likely be affected by 

 change in diet. 



Except for the change in the basis of comparison, experiment 6 was practically a 

 replica of experiment 5. The results being tabulated as in experimeatt 5, no further 

 explanation should be required.
