PLATE 32 



A-B. — A cow (No. 648) and her calf, showing the effect in 1915 of a ration of wheat 

 grain, wheat straw, and alfalfa hay. With half of the roughage as alfalfa hay repro- 

 duction in the first gestation period was successful . The calf was normal and strong, 

 and the cow was apparently healthy and vigorous. 



C-D. — The same cow (No. 648), showing the effect in 1916 of the second gestation 

 on the same ration, wheat grain, wheat straw, and alfalfa hay. This calf was carried 

 to full time, but was weak and at first was fed from the bottle. It grew strong, but the 

 fore legs were so weak that it stood for the first few days of its life on the first joints. 

 This calf was blind. The mother remained in apparently good condition. This 

 again illustrates the cumulative effect of wheat toxicity. 



E. — A cow (No. 662) and her calf, showing the effect of a ration of com meal, starch, 

 wheat embryo, and com stover. Successful reproduction in the presence of the 

 embryo. At least for the first gestation the "antidotal" properties of com meal and 

 com stover were sufficient to overcome the toxic effects of the wheat embryo. With- 

 out the com meal and with only wheat embryo, starch, and com stover in the ration 

 reproduction -vfrould have been premature and the calf either dead or markedly under- 

 sized. (See PI. 30, D.)
