The decrease in the milk production of the 3 cows for the entire period of 101 days 

 was, respectively, 35.55, 24.11, and 29.03 per cent; wdule during the same time the 

 average decrease in the milk production of 10 other cows of the station herd was 

 37.5 per cent. 



Milk investigations at Garforth, 1903, C. Ckowther {Trans. Higldand and 

 Aijv. Soc. Scotland, 5. ,svr., IG {1904), pp. 268-325, dgms. 6). — This is in continuation 

 of work reported by Ingle (E. S. R., 14, p. 1113), the object of which was to deter- 

 mine the chief factors influencing the yield and quality of milk. The present inves- 

 tigations were made with 18 cows and lasted 52 days, the object being to determine 

 if the variations in yield and quality of milk due to milking at imeciual intervals 

 could be lessened by the method of feeding. 



The cows were divided into 4 groups. Group 1 was fed a grain ration consisting 

 of 2 lbs. of undecorticated cotton-seed cake, 2 lbs. of decorticated cotton-seed meal, 

 and 1 lb. of wheat meal, divided equally between the morning and evening feeding. 

 Group 2 was fed 1 lb. of undecorticated cotton-seed cake and 1 lb. of corn meal in 

 the morning, and 1 lb. of cotton-seed cake and 2 lbs. of corn meal in the evening. 

 Group 3 was fed grain only in the morning, the ration consisting of 2 lbs. of unde- 

 corticated cotton-seed cake and 3 lbs. of corn meal. Group 4 was fed grain only in 

 the evening, the ration being the same as for group 3. All the cows were fed the 

 same as group 1 for several weeks previous to the experiment. 



The results are presented in detail and discussed at considerable length. It was 

 foimd that changing from a narrow to a wide nutritive ratio increased the yield of 

 milk but decreased the fat content, the change being more pronounced in the morn- 

 ing's than in the evening's milk; and also that feeding all the grain ration in the 

 morning tended to increase the fat content of the morning's milk, which latter result 

 confirms the conclusion previously drawn by Ingle. Feeding all the grain in the 

 evening also tended to increase the fat content of the morning's milk, but had appar- 

 ently little or no effect on the evening's milk. These changes persisted for a num- 

 ber of weeks after the conclusion of the experiment proi)er. 



While milking at equal intervals is believed to be the best method of preventing 

 the fat content of the morning's milk from falling below the legal standard of 3 per 

 cent, and should be adopted wherever possible, the results nevertheless show that 

 the fat content of the morning's milk may be increased ))y feeding a liberal supply 

 of highly nitrogenous feeding stuffs in the morning. During the summer months 

 the average fat content of the morning's milk of the herd under investigation was on
