ANIMAL PRODUCTION. 73 



iiiid Uien the sluirls, l)i(i(i(l meal, cotton-seed meal, and lukewarm water are 

 added. At the end of 10 days the calves received twice daily, in addition to a 

 pint of milk, soup from 4 oz. of navy beans, 3 oz. shorts, 1 oz. blood meal, and 

 about half the time 3 oz. of cotton-seed meal. "The calf receives this ration 

 until it is (j weeks of age, when the milk is discontinued and the same amount 

 of the substitute fed as before until the calf is 4 months old, when it is weaned, 

 that is. put on dry feed entirely." 



O'cservations on sheep breeding from records of the University flock, C C. 

 IIiMPHKEY and F. Kleinheinz {WiscoiiKin .S7«. Rpt. 1901, pp. 25-40). — From 

 the station records, which have been kept for 240 ewes and which cover a 

 period of H years in continuation cf i)revious work (E. S. It., 14. j). GSf)), the fol- 

 lowing conclusions were drawn : 



"The normal period of gestation, or the time from which a normal ewe is 

 bred to the time of lambing, ranges from 145 to 151 days, and the greatest per- 

 centage of ewes will lamb 147 days after service. 



'• The gestation period appears to be somewhat longer for the male than for 

 the female. 



•' The percentage of males born is practically the same as that of females. 



" The larger percentage of lambs born on or before the 147th day of preg- 

 nancy is strong, and after this time the number of weak and dead lambs is 

 greatly increased. 



"The number of days a lamb is carried in utero does not seem to have any 

 effect on its size. 



" The largest percentage of increase is due to twin lambs, and there is no 

 appreciable difference in the percentage of twins of the different breeds. 



" The production of twin and triplet laml)s is detrimental to the strength and 

 vitality of lambs at birth. 



" Shropshire ewes appear to be more prolitic than any other breed. 



" Ewes () years old produce the largest ])ercentage of increase, while young 

 ewes have the greater percentage of single lambs. The percentage of ram lambs 

 increases and the iiercentage of ewe lambs decreases as the age of the ewe 

 advances. 



"A ram is at his best at 2 and 3 years of age. 



" The age of the ram does not have any eft'ect ou the sex of the offspring. 



"Ram lambs average about one-half pound heavier at birth than ewe lambs. 



" The lai'ger the ewe the greater the pei'centage of increase, while the ram 

 has no effect on the lambs in this respect. 



" The size of the ewe and not the size of the ram determines the size of the 

 lamb." 



Notes on goat keeping, V. Nauckiioff {Mcdilcl. K. Lundtbr. ^Sti/r. [Kircdcn], 

 turn, Ao. in (129), pp. 2S, pi. 1). — The data reported were collected on a trip 

 to Schleswig-Holstein and North Germany. 



The value of different kinds of green forage for hogs, H. J. Waters 

 {Missouri Hta. Bui. 79, ///>. 3-12, pgs. 6). — Corn meal with rape, alfalfa, red 

 clover, and blue grass was fed in comparison with corn meal and shii) stuff 

 3 : 2, and corn meal and skim milk 1 : 3 in a test made with 6 lots of G pigs, 

 weighing about 50 lbs. each. The test covered 102 days. The lots were kept 

 in separate pens with a shetl for protection and the green forage was given 

 twice daily in a separate trough immediately after cutting. 



" It was not expected that in ordinary farm practice the green material would 

 be cut and fed to the hogs in this manner. At the time the experiment was 

 undertaken, however, it was not feasible to fence oft" areas of <?ach of these 

 forage crops and graze thyiu,"
