Calf Rearing Experiments. 



During the second summer {i.e. in 1902) the batch of calves 

 which had received cod liver oil in the rearing period showed 

 the largest increase. Next come Lots IV. and II., whilst Lot I. 

 did not thrive so well as the remaining three lots, though they 

 did better than the latter in the rearing period and in the 

 winter 190 1-2.

In November, 1902, the cattle were sold, but the feeding
