1121 - Digestibility of Very Young Veal (i). — i,an*gworthy, c. r. and holmes, a, d. in

The sale of calves aged less than 3 to 6 days is prohibited in the United 

 vStates b\^ Federal and State laws. Yet in regions where the dairy indus- 

 try is highly developed, milk is such an important product that it is not 

 thought profitable to rear calves beyond the period when the mother's 

 milk becomes saleable, and so, even though they cannot be marketed as 

 butcher's meat they are often slaughtered at 3 to 6 da^'^s old. 



The prejudice against young veal is inspired chiefly by a belief that 

 it is indigestible and ma}' cause physiological disturbances. In order to 

 determine how far this belief is founded on fact, various investigators have 

 compared the meat of very young calves with that of more mature calves, 

 both in respect to their chemical composition and their digestibility. On 

 the whole the balance of evidence goes to prove that very yoimg veal is 

 not unsuited to use as human food. As very little information, however, 

 is available as regards the co-eificient of digestibility of very young veal, 

 a series of experiments was undertaken, to determine the completeness 

 of digestion of this material by the hum.an subject in normal health. 



Five active 3'oung men were selected as the subjects of the experiments. 

 An average of 237 gms. of meat (from calves not more than 5 days old), 

 furnishing 78 gms. of protein or 75 per cent of the total protein of the diet, 

 was eaten daily by each man. The results showed that the digestibility 

 of total protein and that of the meat protein alone were practically iden- 

 tical (92.9 and 92.7 per cent). 



The experiments were repeated with the same subjects, but using 

 market veal in the place of the very young veal. The digestibility of the 

 protein in the total diet was again 92.9 while that of the meat was 92.8. In 

 other words ver^' yoimg veal and market \'eal were found to be eqtialh' 

 digestible. No phj'siological disturbance of any kind were experienced 

 by the subjects either during the ex]:>eri mental period or afterwards. 



1 122 - Disadvantage of SelMng Cotton in the Seed. — Cressuell, c. !■ . United states De-

The practice of selling cotton in the seed, though less prevalent than 

 formerly, is still fairly common in the United States. In regions where 

 the crop is not grown in sufficient quantities to attract regular buyers, the 

 producer is thereby enabled to raise cash on his harvest more quickly than 

 he would by the sale of ginned cotton. As a matter of fact , the advan- 

 tage is a small one and onh^ amounts to the saving of the time he s])ends 

 in waiting his turn at the gins. Baled cotton being saleable directly to 

 merchants and liable to make the farmer independent of the middleman, 

 ginners do not encourage the sale of ginned cotton, more especially as in
