 reference to farm animals, I'. Tangl Landw. Jahrb., 84 I 1905 I, No. 1, pp. . 

 The investigations, which are being carried onal the experiment station in Budapest 

 for the study of animal physiology, are briefly outlined.

Calf rearing, W. T. Lawren< e [Jour. Bd. Agr. [ London], ii I 1905), No. 12, pp. 

 The Bj stem of feeding calves practiced by a successful feeder in the 

 north of England is described, the data being based on observations extending over 

 a period of 9 years. 



After 2 weeks whole milk is gradually replaced by skim milk and cream substi- 

 tutes, those which have given the most satisfactory results being boiled linseed, 

 ground linseed, and cod-liver oil. The scalded ground linseed is considered the 

 most satisfactory. Two sorts of calf meal of domestic manufacture are spoken of. and 

 rations suggested in which they are used. 



Regarding the use of cotton-seed meal, the following statements are made: 



"Loss among calves is often attributed to the useof cotton cake with the cows, 

 hut at this farm the cows when housed get in the regular way 4 lbs. of decorticated 

 cake each per day, and for the latter half of the summer 2 lbs., ami yet. with the 

 exception of [5 calves which died from other causes], there have been no losses in 9 

 years out of a total of 180 calves born. It should, however, be stated that when a 

 cow's milk falls to 5 qts. a day cake is entirely discontinued, as she does not pay for 



it and can be kept in g 1 condition without it, so that practically no cow gets 



cotton cake for at least 2 months previous to calving, nor does she get cake in the 

 week following; but after the first week of its life a calf is fed with the milk of any 

 cow, or with the milk of several, that are receiving the usual allowance of cotton 

 cake." 



Calf feeding experiments, .1. Mahon (Queensland Agr. Jour., i~> (1905), No. .'. 

 pp. 825, 826). — In a test covering 6 weeks it was found that the average daily gain 

 of 4 calves fed l' oz. of cod-liver oil and 8 gal. of skim milk was 1.88 lbs., as com- 

 pared with 1.66 lbs. in the case of calves fed a ration of 10 oz. of pollard, 3 oz. lin- 

 seed meal, 2 oz. molasses, and 3 gal. skim milk. "The use of cod-liver oil facilitates 

 the feeding of calves, and also lessens the danger of scouring which frequently occurs 

 w heii improperly prepared or unsuitable food is fed to calves." 



Raising calves on skim milk and pasture, J. S. Moore I Mississippi Sta. Rpt. 

 1904, />. .'.'). — Calves wen- put on a skim-milk ration when 5 'lays old and fed grain 

 and hay in addition as soon as they would eat it. In 391 days, the average weight 

 was 496 lbs., and the total cost of the feed $11.47 per head. 



How four hundred calves were wintered on ensilage, II. Jones (Prairii 

 Warmer, 71 (1905), No. ft?, p. l,fig. 1). — Calves were fed corn and soy-bean silage ad 

 libitum (25 to 30 lbs. per day), with clover, alfalfa, and oat hay. The -rain ration 

 consisted of 1 to "J lhs. of cotton-seed meal, and for the last 6 weeks 5 lbs. corn-and- 

 jbob meal also. The average daily gain in the 5 months of the test was 1.78 lbs. per 



head, and the cost of a pound of gain 3.6 cts. 



Experiment in beef production, \Y. J. Kennedy bt ai.. | Iowa Sta. Bui. 81, pp. 

 .—Using - Jersey and 2 Fiolstein steer- as representatives of the 

 dairy breeds, and 2 Angus and a like number of high-grade Hereford steers a- rep- 

 resentatives of the heef type, a feeding test covering a year was made. 



Both lots received the same ration of mixed mains and mixed hay with sorghum 

 during July and August The rations varied from month to month, the amount of 

 corn being increased as the feeding period progressed. The average gain per steer in 

 the case of the beef type was 606 lhs.; the average amount of dry matter required
