tween the adequacy of the family dietary and the income level, the home 

 production of foods, and the location of home (farm, village, city). 

 Tabulations and analysis of the results are now under way. (Alice A I.

Varieties of Fruits and Vegetables 

 For Home Preservation 



Fifteen varieties of fresh strawberries were judged for quality of 

 texture, color, shape, and flavor. Of these, Ambrosia, Narcissa, Dresden, 

 Shelton, Tupper, Pathfinder, and Fairfax rated highest. Strawberry 

 preserves were prepared from eight varieties of strawberries. The fol- 

 lowing varieties gave good-quality preserves: Dresden, Pathfinder, Am- 

 brosia, and Shelton. 



There was little difference in the suitability of either the Yellow 

 Spanish or Gov. Wood varieties of light sweet cherries for home freez- 

 ing or canning. For freezing, the Aiontmorency cherry was superior to 

 the Early Richmond. Bing, Schmidt, and Black Tartarian, varieties of 

 the dark, sweet cherry, were all suitable for freezing. In each case the 

 unpitted cherries ranked higher than the pitted. 



Among the raspberries tested for freezing, Indian Summer ranked 

 highest in quality. The fruits used in this study were provided by the 

 horticulture department. (Wilma D. Brewer) 



Nutrition Studies with Dairy Cattle 



The study of the protein and of the energy requirements for growth 

 of dairy heifers includes ten complete balances of the ingo and of the 

 outgo of matter and of energy on animals up to about 33 months of age. 

 A series of basal metabolism experiments on calves from birth up to four 

 months of age, which are now under way, will complete the study of the 

 growth phase of this project. 



The result of primary interest at this particular time brought out by 

 these studies relates to possible economies that can be made in feeding. 

 Although the amount of protein actually consumed was from 20 to 30 

 per cent below the amount which standards in general use provide for, 

 the nitrogen balances showed a retention of this substance indicating 

 protein deposits amounting to over 100 grams per day. This corresponds 

 closely to the actual average daily increase of 1.4 pounds recorded for the 



period. 



In addition to a good quality of early cut hay (native mixed grasses), 

 a simplified concentrate mixture Mas given. The ingredients used were 

 •cornmeal, ground oats, ground barley, and wheat bran, fortified with one 

 part of either linseed meal or cottonseed meal to nine parts of the former. 

 By using the cornmeal, ground oats, and barley in different combinations 

 (under paired feeding conditions) it was found that, as indicated by the 

 nitrogen and energy balances, ground oats and ground barley gave ap- 

 proximately the same results, and both were somewhat superior to corn- 

 meal. 



The project is being continued in a revised form to study the protein 

 and the energy requirements for lactation. (E. G. Ritzman, X. F.
