at 1 per cent less cost for feed. The cows receiving the hirgor amount of jrrani 

 ate 2.4 lbs. less alfalfa per day. 



In a second experiment, cows on pasture receiving a daily grain food of 2 lbs. 

 of cotton-seed meal and 1 lb. of bran produced 3 per cent more milk and 5 per 

 cent more milk fat than cows receiving only the 2 lbs. of cotton-sood meal. 

 Several of the cows were off feed considerable of the time when fed cotton-seed 

 meal alone, but ate their feed more regularly when fed bran with the meal. 

 When fed cotton-seed meal alone the cows produced milk at a cost for feed, 

 Including a pasture charge of $2.50 per month, of 0.72 ct. per pound, and milk 

 fat at 17.5 cts. per pound. When fed 1 lb. of bran daily with the cotton-seed 

 meal they produced milk at O.Sl ct. per pound and milk fat at 19.2 cts. per pound. 

 Cows on the bran ration gained 235 lbs. more in body weight than when on the 

 cotton-seed meal alone. The cows which went off feed on the cotton-seed meal 

 alone usually lost considerable weight, as well as falling off in milk. 



In a third experiment chopped alfalfa was compared with bran as a filler in 

 a grain ration. Each mixture was fed at the rate of 1 lb. for 5 lbs. of milk. 

 The mixture consisting of bran, cotton-seed meal, and ground Kafir corn 2:1:3, 

 produced milk at a cost, for feed, of 0.665 ct. per pound and milk fat at 15.4 cts. 

 per pound. The mixture consisting of alfalfa, cotton-seed meal, and ground 

 Kafir corn 2:1:8 produced milk at 0.578 ct. and milk fat at 14.1 cts. The mix- 

 ture composed of cotton-seed meal and ground Kafir corn 1 : 3, without any filler, 

 produced milk at 0.635 ct. and milk fat at 16 cts. 



On the bran ration the cows gained 202 lbs. in weight and on the alfalfa 

 ration 238 lbs., while on the cotton-seed meal and Kafir corn meal alone they 

 lost 28 lbs. 



In an experiment to determine the value of silage in the ration it was found 

 that cows fed a daily ration of 15 lbs. of alfalfa, 30 lbs. of silage, and 1 lb. of 

 grain for each 5 lbs. of milk, produced $121.38 worth of milk from feed costing 

 $69.72. Cows fed all the alfalfa they would clean up, amounting to 35 lbs. per 

 day, and grain at the rate of 1 lb. for each 5 lbs. of milk, produced $119.34 

 worth of milk from feed costing $88.87. The silage ration produced milk at a 

 feed cost of 0.931 ct. per pound and milk fat at 19.6 cts. per pound. The ration 

 without silage produced milk at 1.178 cts. per pound and milk fat at 25.5 cts. 

 per pound. Crediting all of the profit to the alfalfa used, the silage-fed cows 

 returned $28.32 worth of milk for each ton of alfalfa, and the cows receiving 

 no silage, $14.64 worth of milk for each ton of alfalfa. 



Black and white Ayrshires, A. H. Kuhlman (Jour. Heredity/, 6 (1915), No. 

 7. pp. 3Vf-322, figs. 4). — The author comments on the probable origin of the 

 Ayrshire and its purity of breed. The black and white colors are said to be as 

 old as the breed. A comparison of the registration in 1886 and in 1913 showed 

 a decrease of about 10 per cent in the number of white and brown cows. In 

 1913 there was shown to be a remarkable similarity in the percentage of cows 

 and bulls of the different colors, which was not the case in 1886. In 1913 there 

 were only about one-half as many black and white cows as either red or white. 



There is at present a tendency to select sires with much white. Of almost 

 1,000 bulls registered in volume 36 of the Ayrshire Herd Book, published in 

 1913, 34 per cent were brown and white, 41.93 per cent were white and brown, 

 and 12.64 per cent had the brown restricted to the head and neck. 



On the inheritance of an aural abnormality in the Ayrshire cattle, J. 

 Yamane (Jour. Col. Agr. Tolxoku Imp. Univ., 6 (1915), No. 7, pp. 168-170. pi. 1, 

 figg^ S). — The author gives an account of the abnormal peculiarity, nicked or 

 notched ears, frequently found in some families of the Ayrshire breed of cattle. 

 This peculiarity is said to have originated in Scotland over 50 years ago, and
