The Argentine live stock show, 1902 {An. Soc. Rural Argentina, 1903, Spec. 

 No., pp. 132, pis. 10, fi(ji>. 50, dgin. 1). — In tliis bulletin, which is edited by A. Ben-

The animal industry of Argentina, F. W. Bicknell ( U. S. Dept. Agr., Bureau 

 of Animal Indastvij Bid. 4S, pp. 7:2, ph. 16). — With the object of showing the possi- 

 bilities of Argentina as a market for pure-bred American live stock, the author dis-

Experiments in cattle feeding, J. N. Price {Rpt. Missouri State Bd. Agr., 3-5 

 {190;?), pp. 361-367). — Summarizing data obtained in experiments at the Missouri 

 Station, the relative merits of different methods of cattle feeding are discussed. 

 Information was secured from a large number of cattle feeders in Missouri, Iowa, 

 and Illinois regarding the gains made on full feed in winter and summer. On an 

 average the winter gain reported was 2.2 lbs. per steer per day as compared with 

 2.85 lbs. in summer. 



Fattening- steers; using cotton seed, cotton-seed meal, wheat meal, wheat 

 straw, and hay {OHahonia Sta. Bid. 58, pp. 47). — Conditions and results, F. ('. Burtis 

 (pp. 1-38, 42-45). — Methods of feeding cotton-seed mixtures and the length of time 

 they should be fed were studied with 5 lots of 5 steers each, the test covering 105 

 days in the winter. The lots were all fed in j-ards with sheds open to the south, and 

 in every case the rations selected were made up in such away that at a minimum cost 

 they supplied as nearly as possible the nutrients called for by the feeding standards. 



Lot 1, on cotton seed and cotton-seed meal, 4 : 1, with wheat straw and i^rairie hay, 

 gained on an average 1.77 lbs. per head per day, the cost of a pound of gain being 

 8.8 cts. On wheat meal and cotton-seed meal in about the proportion of 3 : 1, fed with 

 the same coarse fodder as above, lot 2 made an average daily gain per head of 2.62 

 lbs., the cost of a pound of gain being 8.5 cts. Lot 3 on cotton seed and wheat meal 

 in about the proportion of 2 : 1, with the same coarse fodder, gained 2.07 lbs. per 

 steer per day at a cost of 8.1 cts. AVhen cotton-seed meal and wheat straw 1 : 2 were 

 fed, as in the case of lot 4, one-half the straw being cut and mixed with the meal, 

 the average daily gain was 1.76 lbs. per head and the cost of a jsound of gain 9.3 cts. 

 In the case of lot 5, cotton seed was fed with practically an equal amount of coarse 

 fodder (wheat straw and prairie hay), the average daily gain being 1.25 lbs. per 

 head and the cost of a pound of gain 10.5 cts. 



The grained consumed per pound of gain ranged from 5.75 lbs. in the case of lot 2 

 (fed the wheat meal and cotton-seed meal) to 7.32 lbs. in the case of lot 1 (cotton 

 seed and cotton-se^d meal). The amount of coarse fodder eaten per pound of gain 

 ranged from 3.82 lbs. with lot 3 (cotton seed and wheat meal) to 10.67 lbs. with lot 

 5 (cotton seed with wheat straw and prairie hay). 



The steers were sold and slaughtered, the net returns per lot ranging from $24.25 with 

 lot 5 to !?47.57 with lot 3. The dressed weight ranged from 53.2 per cent with lot 1
