DAIRY FARMING DAIRYING. 1005 



author's opinion the last year has been a very successful one for the local poultry 

 industry. 



How frequently does the setting- hen turn her eggs? II. V. Prince (Cornell 

 Countryman, 3 I 1906), No. 6, p. lS9,fig. 1).— From observatione made with a Dumber 

 of hens it was found thai in every instance the eggs were moved every day and did 

 not remain in t he same pari of the nest for more than •"» days. "The thorough man- 

 ner in which the hen turns tin* eggs may well furnish OS a clue t" the -t natural 



and proper treatment of tin- eggs when under the artificial condition- of the 

 incubator." 



DAIRY FARMING DAIRYING. 



Dairy investigations in the northeast of England, I >. A. <in< BTBI8T and ( !. B. 

 Jones I Trans. Highland and Agr. Soc. Scot., 5. ser., 18 I 1906), pp. 68 '. i I. Studii a of 

 variations in the com posit ion of milk and their probable causes have been in progress 

 for a number of years, some of the results of which having already been reported 



l S. It., 15, p. 906). 



The experiments in 1904-6 Bhowed mat when cows were milked at 6 a. m. and 6 

 j». m., the morning milk contained on an average I per cent of fa1 and tin- evening 

 milk .'!.<'» per cent, but when the cow- woe milked at 6 a. m. and 4 p. m., the per- 

 centages were respectively 3.6 and 4.3. The average daily yield of milk was some- 

 what greater when the intervals between milkings woe equal. Some creaming tests 



are also reported. 



Milk investigations at Garforth, 1905, ( '. Crowtheb (Trans. Highland <m<l 

 Agr. Soc. Scot., ■'>. ser., IS' {1900), pp. 1W-14-). — Feeding grain to cows on pasture was 

 studied experimentally with 2 lots of 5 animals each, in periods lasting from July 18 

 to October 9. Commencing with a daily ration of 2 lbs. of undecorticated cotton- 

 seed cake and - lbs. of decorticated cake, the amount of the latter was increased 

 to 4 lhs. and later to 6 lbs. Dnder the conditions of the experiment the smaller 

 ration proved insufficienl for maximum production and the most liberal feeding was 

 far from economical. 



Milk records, J. Speik (Trans. Highland <t,i<l Agr. Soc. Scot, 5. ser., is \ 1906 ./•/>. 

 /.;; 280). Tests woe made of 815 COWS belonging to 30 herds. Two milk-record 

 societies were represented. The tests of IS herds were made every L'l days during 1 

 year and of the remaining herds every It days for .".1 weeks. 



Calculated t<> a basis of milk containing 3 percent of fat, the average production 

 of cows tested Eor the entire year was 875 gal. The average production of io per 



cent of the best cows of these herds was 1, 170 gal. of '■'> per cent milk, and of 10 per 

 cent of the poorest cows, 677 gal. Ten per cent of the best cows in the remaining 

 herds produced, on an average in :\\ week-. 826 gal. of ,", per cent milk, and 10 pel- 

 cent of the pooresl cows. 526 gal. Tables are also given showing the milk produc- 

 tion according to the age of the cows. 



Influence of asparagin on milk production, T. Pfeiffeb (Abs. in Centbl. Agr. 

 CIkiii., .!■'> (1906), No. J, pp. 48-61). — In experiments with goats, the substitution of 



asparagin for a pari of the proteids in the ration produced a marked decrease in tin- 

 fat content of the milk without materially lowering the yield, and was unfavorable 

 to the growth of the animals. 



Feeding- dairy cows, ( '. I>. Smith (Michigan Sta. />'"/. .'■'•',, /'/>• 86-109). — This is 

 essentially an abridged form of bulletin 149 of the station (E.S. R., '•'. p. 1081). 



Is the passage of food fat into milk demonstrable by the Winternitz 

 method of feeding iodized fat? S. (iOGrriDSE (Ztschr. Biol., 4") (1906), \<>. .',, 

 />/>. 476-486). — This is a critical review of the literature of this subject with a bibli- 

 ography. The method, as broughl forth by K. Winternitz, consists in feeding the 

 animal iodized fat and examining the milk for the presence of iodin. The author's
