ANIMAL PRODUCTION. 77 



"Cotton-seed meal gave the l)etter results when comhined with corn meal in the 

 proportion of 1 lb. of the l\)rmer to 1^ lbs. of the latter than wlien fed alone. . . . 



"The results of this experiment favor the use of a ration of corn stover, cowpea- 

 vine hay, and corn meal in preference to one of shredded stover, cotton-seed bran, 

 and cotton-seed meal." 



Salt for fattening cattle, J. G. Haney (Industrialisl, 21 {1901), No. 20, pp.

 a mm.lier of grade calves. 



The comparative feeding- value of corn fodder, corn silage, roots and hay, 

 for feeding- breeding ewes in winter, A. L. Carlylk ( Wiscontiiii. t^tn. Rpt. 1900, pp. 

 2S-o'J). — Using 3 lots of 12 and 1 of 11 ewes, a number of rations were compared for 

 winter feeding, with especial reference to the value of corn fodder and silage. Lota 

 1 and 2 were fed corn fodder with bran and oats (1:1), lot 2 receiving corn silage in 

 addition; lots 3 and 4 were fed hay, with bran and oats (1:1), the former receiving 

 corn silage and the latter roots in addition. The ewes in lots 1, 2, and 3 were given 

 I lb. of grain per head daily, and those in lot 4, | lb. In 10 weeks the lots gained 

 197, 122, 154, and 159 ll)s., respectively.. Data are recorded concerning the produc- 

 tion of lambs by the different lots, also the weight and condition at l)irth. "There 

 was not very much difference in the average length of time that the ewes of the 

 different lots carried their laml)s. . . . Nothing of any importance can be gleaned 

 from these slight differences in this respect, and the same may be said of a comparison 

 of the number of days in pregnancy of the ewes of different breeds on this experi- 

 ment. There is also very little that is noteworthy in a comparison of the number or 

 the condition of the lambs produced by the different lots, except the uniformity of 

 increase and general vigor of the lambs from all the flock, irrespective of the kinds 

 of feed given the ewes. . . . 



" Well-cured corn fodder, of which al)out 65 per cent has had the ear corn removed, 

 was a satisfactory feeding stuff. . . . 



" Corn silage fed in conjunction with either corn fodder or mixed hay and the 

 same ration of bran and oats is a very satisfactory and very cheap ration for winter 

 breeding ewes that are pregnant. This experiment w'ould also seem to indicate that 

 hay and roots make a very exi)ensive feed ration for wintering breeding ewes and that 

 they do not give any better results than the other and cheaper rations fed. It would 

 appear also that corn fodder containing a large proportion of ears shovdd not be fed 

 largely to breeding ewes until the ear corn had been removed, as w^ell cured and 

 unhusked corn fodder may have fully 50 per cent of its weight in the ear corn, and 

 the ewes might readily get too niucli ear corn and 1)ecome too fat.'' 



Pig feeding experiments: Fattening value of certain foods grazed by pigs; 

 feeding experiments to harden soft pork, R. L. Bennett {Arkansas Sta. Bui. 65, 

 pp. 57--? -?C).— Tests of the value of forage crops for pigs (E. S. R.,10, p. 1065) have 

 shown that i)ork produced by grazing on such foods as soy beans, peanuts, and 

 chufas lacked the hardness of corn-fed pigs. A test was therefore undertaken to 

 learn what quantity of corn was required, and how long it was necessary to feed it 

 after grazing in order to secure carcasses of the desired quality. A lot of 10 mixed 

 grade pigs averaging 116.7 lbs. in weight was pastured for 60 days on peanuts and 

 chufas planted three rows of the former to one of the latter. The average daily gain 

 per ])ig was 1.6 lbs. A similar lot of 10 jiigs averaging 116.2 lbs. each at the 

 beginning of the test was pastured 60 days on peanuts. At the close of the period 

 the pigs in lioth lots were put on full corn fodder for 8 weeks, the amount of corn 

 eaten being recorded. At intervals of 2 weeks the 2 fattest pigs were slaughtered 

 and the melting point of samples of fat tested. 



For puqwses of comparison, three lots were pastured during the wiioli^ test on pea- 

 nuts and <'hufas alone and cond)ined. Four i)igs weighing an average of 115.5 lbs. 

 each when pastured on chufas for 60 days made an average gain of 1.38 lbs. Two
