74 EXPERIMENT STATION RECORD. 



The production of brown or tinted eggs (Jour. Bd. Agv. [LoHf/O)?!, 12 

 (J006), A'o. 10, pp. G11-G13). — Since brown-slielled eggs are preferred in the 

 British niarljet and bring a higher price their production is discussed. Lang- 

 shans. Cochins, Plymouth Rocks, Orpingtons. Game. Wyandottes. Brahnias. 

 Faverolles, and Coucous de ^Maliues produce eggs of the desired color. A 

 innnber of satisfactory crosses are also suggested. " In crossing two breeds 

 producing respectively white and tinted eggs, it is necessary to depend chiefly 

 upon the females for conservation of tlie tinted characteristic, and it is 

 advisable that in such crossing the m;ile only should be selected from the white 

 egg-producing races." 



Egg production of virgin fowls, J. Nelson {New Jersey Stas. Rpt. IDO.'), pp. 

 393- 'lOO). — The presence <if the male bird on egg production was studied, but the 

 results obtained up to the present time are not regarded as sufficient for general 

 deductions. In general, more broody hens were noted in the lot having the 

 male bird, but the differences were not very great. 



DAIRY FARMING DAIRYING. 



Feeding experiments, G. A. Billings {Neir Jersey Stas. Rpf. /.Ory.T, pp. 

 336-349). — The feeding experiments reported in 2 recent bulletins of the station 

 (E. S. R., 17, p. 000) are summarized and an account is given of a comparative 

 test of 2 grain rations, one consisting of 5 lbs. of dried distillers' grains and .1 

 !l)s. of wheat bran, and the other of 4.5 lbs. of dried brewers" grains, 4.5 lbs. of 

 wheat bran, and 1 lb. of cotton-seed meal. The test was made with 4 cows and 

 lasted 30 days. The first ration mentioned, as compared with the second, 

 increased the average daily yield of milk 5 lbs. per cow and the fat content 0.07 

 per cent and decre;ised the cost of production 11.4 cts. per 100 lbs. of milk and 

 1..32 cts. ])cr ponnd of l>utter. 



Experiments with the dairy herd, G. A. Billings (Neir Jersey Stas. Rpl. 

 1905, pp. 376-390, pis. 6). — The improvement of dairy herds is briefly discussed 

 and an experiment in breeding a pure-bred Guernsey sire upon common stock is 

 reported. The records of 1 dam and 4 heifers are given. In every instance the 

 fat content of the milk of the offspring was higher than that of the mother. 

 This practice is recommended not only for increasing the fat content of the milk 

 but for giving the milk a higher color. 



Notes are given on the construction of concrete mangers for cattle and on 

 improvements in the milk room at the station, including the laying of a con- 

 crete floor. 



The value of keeping milk records is illustrated by the records of the colU^ge 

 herd. The data obtained during 9 years on the cost of producing and handling 

 milk indicate that cows producing yearly less than 5,000 lbs. of milk containing 

 4 per cent of fat are unprofitable. With milk at 3 cts. per quart the records 

 show that 30 cows have returned profit over and above the value of manure, 

 while 11 were unprofitable. With butter at 20 cts. per pound only 13 out of 44 

 cows showed any profit above the manure after deducting for feed, labor, 

 interest on the cai)ital invested, and depreciation of the herd. 



Dairying, J. J. Vernon (A'e/r Mexieo Sta. Rpt. 190), pp. 28, 29). — In experi- 

 ments with 8 cows, feeding bran with alfalfa hay was compared with feeding 

 alfalfa hay alone. In 12 weeks 4 cows consumed 11,207 lbs. of alfalfa hay and 

 2,700 lbs. of bran and produced 5.r)43 lbs. of milk, while 4 cows fed alfalfa alone 

 consumed 11,378 lbs. of hay and produced 4.028 lbs. of milk. 



Tests of Guernsey cows for advanced registry {Connecticut State St a. Rpt. 

 1905, pt. U. I). 3)3). — Nine cows were tested during the year, the records of 3 

 being given.
