866 EXPEKIMENT STATIOX RECORD, [Vol. 37 



Live stock feeding experiments (Dept. Agr. and Tech. Instr. Ireland Jour., 

 JG {1916), No. 3, pp. J,18-.'f30). — The report deals with experiments carried out 

 during two years, 1913-1915, under the supervision of agricultural instructors 

 in almost every county in Ireland. The following conclusions are drawn : 



In pig feeding raw meal showed a saving in fuel and labor. Cooking failed 

 to give returns either in amount of feed consumed, length of fattening period, 

 or quality of the pork. 



In calf feeding maize meal with separated milk showed practically as good 

 results as a calf meal made up of 1 part ground flaxseed, 2 parts maize meal, 

 and 2 parts oatmeal. 



With cattle the feeding of a mixture of 2 parts uudecorticated cotton cake 

 and 1 part maize meal on second-rate pasture did not give a profitable increase 

 in live w-eight. Indirectly it might give a profit by earlier maturity or better 

 appearance at marketing. 



With stall-fed cattle the extent to which turnips should be used is deemed a 

 question for each farmer to decide. In most cases it seemed sound economy to 

 grow them extensively and feed liberally. Cattle can be fattened successfully 

 with 3 stone (42 lbs.) of turnips per head daily. 



Almost similar results were obtained with two rations, one with 84 lbs. of 

 roots and a moderate amount of concentrate<l food, and one of 42 lbs. of roots 

 and an extra allowance (3 lbs.) of concentrated food. 



Color inheritance in mammals, S. Wright (Jour. Hcrcdily. S (1917), Xo. .5, 

 vv. 22^-235. fiffs. 2). — An attempt is here made to relate the biochemical find- 

 ings in regard to melanin with color relations that have come to light in 

 genetic work. A scheme Is proposed for showing the interrelations of the dif- 

 ferent mammalian coat colors, and a classification of color factors is .suggestetl. 



The value of good sires, .T. K. Wright (Mi.^80uri Bd. Afir. Mo. RuL, H 

 (1016), No. 9, pp. 5-S6, flg». 5S). — This bulletin reviews in a general way the 

 principles of heredity, environment, and variation, and shows by citation of a 

 few great herds and from experimental data from other sources the value of 

 good sires in the improvement of horses, asses, cattle, sheep, and swine. 



The heredity of dual-purpose cattle, H. F. Euren (Noncich, [England]: 

 .A. I). Eurcn. 1911, pp. 96). — A brief history is given of the origin and develop- 

 ment of the dual-purpose Red Polled breed of cattle, including an account of 

 the work of John Reeve, of Wheycurd Hall Farm, Wighton. England, and 

 others in the development of the breetl. 



For the study of the heredity of the Rod Tolled, as evidenced by its milk 

 production and its beef production, the author has prepnred from tlie British 

 and American Herd Books the extended pedigree of 29 cows in the Unitefl King- 

 dom and of 11 in the United States. In each of the pedigrees has been worktxl 

 out the percentage of blood of polled " home-bred " cattle of Norfolk, polled 

 Suffolk, and the Reeve blood-red breed. 



Details are given of the breeding of noteworthy bulls that have been used i,n 

 developing the Red Polled dual purpose cattle, together with data on the cost 

 of feeding for milk and beef. Transcripts are al.so given from the British and 

 American Herd Books showing the butter production and beef-making qualities 

 of some of the leading strains and families of Red Polled cattle. 



Sheep breeding and feeding, J. M. .Tones (Texas St a. Rul. 205 (1917). pp. 

 3-24, fiffS- 5). — The object of this test was to determine which of the most com- 

 mon mutton breeds of rams when crossed with fine-wooled ewes would produce 

 the most thrifty and desirable lambs grown and fatteneil under Texas con- 

 ditions. 



Good Rambouillet range ewes of uniform type and breeding were used, 148 

 ewes being divided into six lots and bred to rams as follows : Lot 1, Rambouil-
