the bran and gluten ration being superior by 13.2 per cent total solids and 14 

 per cent total butter fat. 



Brief notes are also given regarding an additional test which was discon- 

 tinued. The composition and digestibility of molasses, the value of molasses 

 feeds, and other related questions are discussed, some of the data summarized 

 having been noted from an earlier publication (E. S. R., 10, p. 2G4). 



Grains to supplement skim m.ilk for calves, J. R. Fain and ]M. P. Jarnagin 

 {Virfrhiia Sta. Bui. 172, pp. Sl-U'i, fig. 1). — Shelled corn alone and with bran 

 4:1, corn meal and bran 4:1, and cracked barley and bran 4:1 were compared 

 as supplements to skim milk in calf feeding. The system of feeding gave satis- 

 factory results, according to the authors, and was as follows: 



" Ten lbs. of milk for the first 100 lbs, of live weight, 5 lbs. of milk for the 

 second 100 lbs. of live weight, and 2.5 lbs. of milk for the third 100 lbs. of live 

 weight. Until the calf was 3 months old 1 lb. of grain to 10 lbs. of milk was 

 fed. From 3 to 6 months old 1 lb. of grain to 5 lbs. of milk was fed." 



All the calves had access to hay from the start, the amount consumed daily, 

 as shown by a test with calves kept in box stalls for several days at a time, 

 being approximately 1 lb. per each 100 lbs. live weight. The lots were fed 

 from 87 to 115 days, the gains ranging from 1.42 lbs. per head per day on corn 

 meal and bran to 1.6 lbs, on shelled corn alone, and the cost of feed per pound 

 of gain from 3.65 cts. with the last mentioned lot to 4 cts, with the lot fed 

 cracked barley and bran. 



When 4 beef calves were fed for 82 days shelled corn and bran 4 : 1 with 

 skim milk and hay an average daily gain of 1.06 lbs. per head was noted at a 

 cost of 5.45 cts. 



A similar lot fed whole milk with shelled corn, bran, and blood meal 20:4:1 

 with hay in addition gained on an average 2 lbs. per head per day for 91 days 

 at an estimated cost of a little over 10 cts. per pound of gain. 



According to the authors, " the importance of hay for young calves can not 

 be emphasized too strongly; they should have access to good, clean hay at all 

 times. . . . 



" The best results were obtained from shelled corn. The calves did not con- 

 sume as much corn meal per day as shelled corn, nor did they make as large a 

 rate of gain. It did not require as much shelled corn as corn meal per pound 

 of gaiu, . , . 



" Bran was used to great advantage in teaching the calves to eat grain, but 

 no advantage was secured from adding bran to a ration of shelled corn to 

 supplement the skim milk, either in rate of gain or the appearance of the 

 calf. . . . 



" Barley was found to be an excellent grain to supplement skim milk, but 

 owing to its high market price as compared with corn it did not show as good 

 returns financially. However, it must be borne in mind that barley can be 

 produced pound for pound as cheaply as the corn. . . . 



" The group of calves fed whole milk made the largest gain, but at the 

 highest cost per day and per pound of gain. They presented a better appear- 

 ance before weaning, but at 8 mouths of age there was little difference either 

 in weight or appearance between those developed on whole milk and those on 

 skim milk," 



In cases of scours calves were treated with formaldehyde with satisfactory 

 results not only in the tests but also, according to the authors, in a large 

 number of other cases.
