gY2 EXPEEIMENT STATION RECOED. 



but it required 3.5 per cent more feed to make 100 lbs. of gain with Tamworths 

 than with Duroc-Jerseys. In prolificacy both breeds stood high, the Tamworths 

 averaging in 15 litters 3.S pigs to the litter and the Duroc-Jerseys in 21 lit- 

 ters 9.1 pigs per litter. 



The general av«-age of the several lots of the four experiments shows that 

 alfalfa "hay constituted 31.9 per cent of the feed eaten. The quantity ranged 

 from 11.4 per cent with a heavy concentrate ration to 51 per cent with a ration 

 of skim milk. In general, the percentage was high with a light or medium 

 concentrate ration and lower with the heavier concentrate rations. 



The use of the paunch contents of freshly slaughtered cattle as a pig 

 feed {Dent. Landio. Fresse, ^2 (1915), No. 12, pp. 90, 91).— The paunch contents 

 of freshly slaughtered animals is being used as a pig feed in Germany, 100 lbs. 

 of this ruaterial being mixed with 10 liters of blood, 20 lbs. of molasses peat 

 meal, 3^ lbs. of salt, and a little whiting. This has about one-fourth the feed- 

 ing value of an equal quantity of potatoes. 



The Large White Yorkshire pig, S. Heaton {Jour. Roy. Agr. Soc. England, 

 75 {191Ji), pp. 40-50, pi. 1, fig. 1). — A discussion of the breeding, feeding, care, 

 and management of the Large White Yorkshire breed of hogs. 



Poultry, A. F. Eolf and L. F. Payne {OkJalwma Sta. Bui. 106 {19U), pp. 

 SI, pi. 1, figs. 8). — Part 1 of this bulletin deals with breeds and breeding, 

 poultry diseases, and farm poultry housing. Part 2 discusses incubation, brood- 

 ing, and feeding. 



Telling the sex of day-old chicks, W. F. Fry {Rel. Poultry Jour., 22 {1915), 

 No. 5, pp. 593-595, 629, figs. 4)-— It is said that the sex of day-old Barred 

 Plymouth Rock chicks can be determined without difficulty. The male charac- 

 teristics are the coarser appearance of the chick's head, the greater admixture 

 of white with black in the plumage, which gives a lighter-gray effect, and the 

 clear yellow color of leg and beak. The female characteristics are a neater 

 head, stronger-black coloring, and dark beak and legs. 



Third annual international egg-laying contest, W. F. Kirkpatrick and 

 L. E. Card {Connecticut Storrs Sta. Bui. 82 {1915), pp. 57-99, figs. 21).— In 

 experimental pens in connection with this contest it was demonstrated that milk 

 may be substituted for green feed or for meat but not for both when the reg- 

 ular contest ration was fed. Birds supplied with a prepared feed for which 

 they did not have to scratch did not do so well as those receiving the ordinary 

 contest ration. 



It was found that the weight of eggs from the different breeds varied con- 

 siderably. The Leghorn eggs averaged about 1.5 lbs. to the dozen, the Wyan- 

 dotte eggs 1.483 lbs., the Plymouth Rock eggs 1.588 lbs., and the Rhode Island 

 Reds 1.602 lbs. The average for all breeds was 1.537 lbs. 



The highest percentage of broody birds was found in the Rhode Island Reds 

 and the lowest in the Leghorns, the average number of days lost for all breeds 

 being 20.9 days per hen per year, while each broody hen lost 56 days. The 

 average for the heavy breeds was 34.3 days. 



At the close of the contest the Leghorns averaged in weight 3.51 lbs. per bird, 

 the Wyandottes and Rliode Island Reds 5.45 and 5.59 lbs., and the Plymouth 

 Rocks 5.94 lbs. The Plymouth Rocks, Wyandottes, Rhode Island Reds, and the 

 miscellaneous group all reached their highest production in the month of April, 

 while for the Leghorns May was the best month. The cost of feed to produce 

 a dozen of eggs was in the case of the Plymouth Rocks 16.1 cts.. the Wyandottes 

 14.3 cts., the Rhode Island Reds 15.8 cts, and the Leghorns 12.4 cts. 

 Yield data, etc., are also Included.
