270 EXPERIMENT STATION RECORD. 



mals will be registered as foundatiou stocli until the end of 1918 under the 

 following conditions : Animals imported from England, though not recorded, 

 that can be shown on sworn testimony to be descended from not fewer than 

 four generations of recorded Shorthorn sires in the case of females and five 

 in the case of males, and that measure up to the requirements called for; 

 animals bred in America that can measure up to the standard called for in 

 the case of unrecorded imported Shorthorns. Before the progeny of recorded 

 animals can be recorded they must be the progeny of recorded dams that have 

 weighed not less than 1,200 lbs. at 30 months old, or not less than 1,400 lbs. at 

 the age of 36 months ; of heifers with their first calf that have produced not less 

 than 3,000 lbs. of milk during the first 6 months of lactation, or not less than 

 4,500 lbs. during the first year ; and of cows at 4 years or over that have pro- 

 duced not less than 6,000 lbs. of milk in a year. 



Milch goats, G. H. True {California Sta. Rpt. 1915, p. 56).— Three milch 

 goats completed a year's record as follows: A 2-year-old pure Toggenburg, 

 2,158 lbs. of milk and 72.8 lbs. of milk fat ; a 2-year-old Toggenburg, 1,118 lbs. 

 of milk and 40.7 lbs. of milk fat; and a yearling-grade Toggenburg, 1.283 lbs. 

 of milk and 49.73 lbs. of milk fat. The feed cost of 1 lb. of milk from these 

 goats was approximately 90 per cent that of 1 lb. of milk of a similar average 

 fat content produced by a group of 5 cows in the university dairy herd. 



The American milch goat record {Dayton, Ohio: American Milch Goat 

 Record Assoc., l',>14, vol. 1, pp. 86). — This is the first volume of this record 

 and contains 900 pedigrees, with an Index to owners. 



Profit and pleasure in goat keeping, F. C. LouNSBxnjv {Plainfield, N. J.: 

 Author, 1915, pp. 43, figs. 23). — A description of the principal breeds of goats, 

 together with instructions on their feeding, care, and management. 



The quantity and quality of milk secreted from the four quarters of the 

 udder, E. Goluoni {Atti Soc. Nat. e Mat. Moden<t, 5. ser., 1 {1914), PP- 69-S6). — 

 The author in his tests of a number of cows found very little difference in the 

 relative quality of milk from the four quarters of the cow's udder, but the qual- 

 ity varied with the individual. However, with all the cows the hind quarters 

 showed a slightly larger yield. 



A bibliography of references is included. 



The action of pituitrin on the secretion of milk, A. L. I. Maxwell and 

 A. C. H. RoTHERA {Jour. Physiol., 49 {1915), No. 6, pp. 483-491).— The authors 

 found in their studies that '* pituitrin " injections cause a gradual rise of milk 

 pressure. This increase of pressure was maintained for at least 17.5 minutes 

 in a goat and at least 40 minutes in a cow. In the goat pituitrin causes extra 

 milk to be available to the milker for a considerable time. If the effects were 

 due to muscular contraction, it is thought that they would rapidly reach a 

 maximum and then decline. In cats about GO per cent of the milk is preformeil 

 in the gland after G to 7 hours' interval and about 40 per cent is secreted 

 during suckling, indicating that suckling causes a true secretion. The effect 

 of suckling is, so far as has been investigated, the same as that of pituitrin, 

 and it is concluded that pituitrin also causes a true secretion. 



On the composition of milk as affected by increase of the amount of 

 calcium phosphate in the rations of cows, A. Lattdbib and T. W. Fagan {Proc. 

 Roy. Soc. Edinb., 35 {1914-15), No. 2, pp. 195-202) .—Two lots of three dairy 

 Shorthorn cows each were fed turnips, cotton-seed cake, bran, hay, and straw, 

 the mineral matter in this ration, exclusive of the straw, containing about 

 0.5 lb. of calcium phosphate per cow per day. On this ration the percentage 

 of phosphoric acid and mineral matter in the milk of each cow was relatively 

 constant. Lot 1 was kept on this ration throughout, while lot 2 was fed in addi- 

 tion for five weeks calcium phosphate in the following quantities : For the first
