99G EXPERIMENT STATION KECORD. 



the greatest gain, averaging 2.49 lbs. per sheep per week, was made on a pasture 

 which had been inanured with 0.5 ton basic slag in 1900 and nothing since. The 

 smallest gain, 1.35 lbs. per head per week, was made by sheep pastured on an 

 unmanured plat. 



Three types of market sheep, W. L. C.vrlyle ( Wisconsin Sta. Rpt. 1903, pp. 

 7'2-74, pi. 1). — On the basis of data derived from an examination of the carcasses of 

 2 sheep of good type fed generously and 1 fed ]ioorly, marked advantages are pointed 

 out for the former method. 



The comparative value and effect upon the lambs of feeding- various grain 

 rations to pregnant ewes, W. L. Carlyle and T. F. McConnell ( Wisconsin Sta. 

 Rpt. 1902, pp. 02-71). — The effect of different grain rations on ewes and their young 

 was studied, dried brewers' grains l>eing found the cheapest, with bran, shelled 

 corn, and oats following in the order named, all the grains being fed at the rate of 

 0.5 lb. per head per day. 



The authors' conclusions were in effect as follows: Any of the grain rations when 

 fed in connection with 2.5 lbs. of corn silage and 2 lbs. mixed hay per ewe per day 

 was quite satisfactory so far as the physical condition of the ewes was concerned. 

 The results would seem to indicate that the ewes fed the rations containing the 

 largest amount of protein drank the largest amount of water. 



When the milk supply of the ewes at parturition is considered, it ajipears that the 

 dried brewers' grains produced by far the best results. Taking into consideration 

 the size and strength of the lambs at birth, it appears that the ration of whole oats 

 and that of dried brewers' grains produced the strongest and heaviest lambs, with 

 the results slightly in favor of the former. 



Corn silage in connection with hay continues to meet with approval as a coarse 

 fodder ration for pregnant ewes in winter. To arrive at more definite results along 

 this line it would be better to have the experimental feeding period extend over a 

 greater portif)n of the time that the young lamb is dependent upon its dam for 

 existence. 



Some observations on sheep breeding from the experiment station flock 

 records, \V. L. Carlyle and T. F. INIcCoxxell ( Wisconsin Sta. Rpt. 1902, pp. 42-61, 

 chart i).— Noted from another puldication (E. S. E., 14, p. 685). 



Experiments in sheep breeding, T. Winter [Bd. Agr. [Londoii'], Rpt. Agr. 

 Education and Research, 1901-2, j>P- 53-56). — In the first of 2 tests made at the 

 University College of North Wales, 3 lots containing respectively 30, 20, and 25 

 small mountain ewes, were bred respectively with a Wiltshire, Shropshire, and 

 Southdown ram. Twenty-nine living lambs were dropped by the ewes in the first 

 lot, 18 by those in the second lot, and 25 l)y those in the third. Part of these were 

 sold for slaughter when 4 or 5 months old, the remainder a month later, the average 

 weight of the lambs in the 3 lots when sold being 68, 68, and 67 lbs., respectively. 



In the second test 4 lots of 15 ewes each and 1 of 21 ewes, in every case large 

 animals, were used. These lots were bred respectively with Border-Leicester, 

 Shropshire, Oxford, Wiltshire, and Suffolk rams, the lambs dropped being 21, 28, 

 19, 20, and 30, respectively. The lambs were sold when ready for market. Taking 

 into account the number of early and late sales and other data, the conclusion was 

 drawn that the Suffolk cross gave the best results. 



Grazing and feeding experiments with pigs, J. F. Duggar {Alabama College 

 Sta. Bid. 122, pp. 48). — The principal object of these tests, which extended over 4 

 years, was to ascertain the relative pork producing value of some of the hog crops of 

 special imiiortance in the South and to study their effect on the quality of flesh and 

 lard, that portion of the investigation, which treated of forage crops being a contin- 

 uation of work previously reported (E. S. R., 10, p. 577). 



To study the relative gains made before and after weaning, a sow and litter of 7 

 pigs about 1 month old were hurdled on vetch and turf oats and fed some corn in
