ANIMAL PKODUCTION. 73 



271). — ^A revision of a compilation of the composition, digestibility, and fer- 

 tilizing ingredents of feeding stuffs made at the Massachusetts College and 

 Station and its predecessors. 1S6S-1910, previously noted (E. S. R., 18, p. 278). 



Coefficients of digestibility of American fodder articles. — Experiments 

 made in the United States, J. B. Lindsey and P. H. Smith (Massachusetts 8ta. 

 Rpt. 1910, pf. 1, pp. 273-303). — This revision of a compilation previously noted 

 (E. S. R., 18, p. 261) includes digestion coefficients resulting from expei'iments 

 made in the United States, intended to be complete to December, 1910. A 

 bibliography of publications of the state stations consulted in compiling these 

 tables is appended. 



Scale of points for Friesian cattle (Agr. Jour. Union So. Africa, 1 (1911), 

 No. 5, pp. 690, 691). — This contains the scale of points of an ideal form of 

 Friesian cattle, as stated in the Friesian herd book (Friesch Rundvee Stam- 

 boek). It is stated that there is no official scale for judging South African 

 Friesian cattle, but that good judges of the breed adopt either those of the 

 Friesian herd book or the American Holstein-Friesian herd book, placing 

 emphasis upon particular points applicable to South African conditions. 



The blue breed of the north, R. Dumont (Jour. Agr. Prat., n. ser., 22 (1911), 

 No. 36, pp. 304, 305, pi. 1). — X description of this popular dual-purpose breed of 

 cattle of France. It is stated that the breed is the result of a cross of the 

 native Belgian with the Durham and Hollandaise. Suggestions are given for 

 the improvement of the breed, and it is urged that improvement be toward the 

 milking type. 



Alfalfa and corn for fattening lambs, H. H. Simpson (New Mexico Sta. 

 Bui. 79, pp. 18, figs. 7, dgm. 1). — These experiments were undertaken to show a 

 comparison of the cost of gain in feeding lambs varying amounts of corn in 

 connection with alfalfa. 



In 1909, 100 wether lambs were divided into 4 lots and fed a period of 73 

 days rations consisting of all the alfalfa wanted and different amounts of corn. 

 The lot fed i lb. shelled corn each daily made a gain of 0.24 lb. daily at a cost 

 of '5.7 ets. per pound of gain ; those fed * lb. .shelled corn made 0.23 lb. gain at a 

 cost of 6.6 cts. per pound gain ; those fed | lb. shelled corn gained 0.28 lb. at a 

 cost of 6.3 cts. per pound ; those fed 1 lb. shelled corn made a gain of 0.31 lb. 

 at a cost of 6.6 cts. per pound; the feeds being valued at $8.50 per ton for 

 alfalfa and $32 per ton for the corn. These results are compared with results 

 obtained with lambs fed alfalfa, corn and Kafir com stovers, and corn in 1901-2. 

 (E. S. R., 16, p. 189.) 



The author states that with local markets which do not make a distinction 

 between finished and unfinished lambs it is more profitable to feed a light grain 

 ration, especially where grains are high priced, selling the lambs just before the 

 final finish period. 



Coyote-proof inclosures in connection with range lambing grounds, J. T. 

 Jabdine (U. 8. Dept. Agr., Forest Serv. Bui. 97, pp. 32, pis. 2, figs. 3). — This 

 reports a continuation of the work (B. S. R., 23, p. 575) on the advantages to 

 be gained through the use of coyote-proof pastures in handling sheep. 



A justification of the results previously reported has been obtained by a 

 private individual who inclosed 500 acres with coyote-proof fence, and in this 

 inclosure 1.000 ewes were lambed. With the services of only one man 100 

 lambs were saved for each 100 ewes. It is stated that this number would have 

 been higher but for the fact that some animal, presumably a coyote, was 

 fenced in the inclosure and preyed upon the lambs. Just outside this inclosure 

 it required the services of 3 men and a pack of hounds to care for 1,000 ewes, 

 and only 95 lambs per 100 ewes were saved. This fence, which is approximately
