Swine, N. Athanassof (Eseola Ayr. " Luiz de Queiro~,'' J'iraeicalxi, Brazil, 

 Bol. 1 (1910), pp. 75, pis. 2, figs. 22).— This is an account of tlie swine industry 

 in Brazil, and deals with breeds, breeding, feeding, fattening, and questions 

 of hygiene. Three native breeds are recognized, the Canastrao (large), the 

 Canastra (medium-sized), and the Tatil (.small and apparently of Asiatic 

 origin). Berlvshires, Large Blacks, Poland-Chinas, and Duroc-Jerseys have 

 been imported and used for crossing. 



The effect of certain grain rations on the growth of the White Leghorn 

 chick and their influence on subsequent egg-production, G. D. Buckner, 

 A. M. Peter, R. H. Wilkins,, and J. J. Hooper {Kentnekij Sla. Bui. 220 (1919), 

 pp. 3-20, pis. Jf). — This bulletin gives data as to (1) the growth in weight of 8 

 variously treated lots of White Leghorn chicks during the first 28 weeks of life, 

 (2) the mortality during that period, and (3) the average egg production of 15 

 pullets from each lot. The work was mainly a continuation of a study of the 

 importance of lysin in chick feeds reported in Bulletin 197 (B. S. R., 34, p. 871). 



One lot (lot 4) were hatched and brooded by hens and had access to a blue 

 grass pasture until the sixth week ; the others were incubator chicks and were 

 confined to a brooder house until 6 weeks old. The methods of feeding lots 1. 

 2, and 3 and the growth records of these lots were presented and discussed in a 

 paper by Buckner and collaborators previously noted (E. S. R., 41, p. 75). Two 

 other types of rations were tested with the remaining lots. Lot 5 were fed a 

 dry mash of rolled oats, ground barley, rice bran, beef scrap, and bone meal 

 (3:3:3:3:1), a scratch feed of "hominy," steeled oats, and rice (2:1:2) 

 and once a day some of the ma.sh moistened with skim milk. This ration was 

 high in lysin of animal origin. Lots 6 and 8 were given a mash of wheat 

 bran, sunflower seed, distillers' dried grains, and cottonseed meal (3:7:1:1) 

 and a grain mixture of wheat, corn, and soy beans (2:2:7), the lysin content 

 of the ration being high. Lot 8 had access to skim milk continuously, while the 

 only animal feed given lot 6 was protein-free milk once a day with the wet 

 mash. All lots received shredded cabbage and sprouted oats, and it is thought 

 that the vitamin supply was ample in all cases. Any deficiency in a ration is 

 therefore attributed to lack of necessary amino acids. The other experimental 

 details and the main results may be summarized thus : 



Influence of amount and source of lysin in feed and the feeding of skim milk on 

 the growth and reproduction of chicks.
