670 . EXPERIMENT STATION EECOKD. 



The results are summarized as follows: 



" Clover hay and grain proved more efficient as a ration for breeding ewes 

 than timothy hay and grain. Clover hay alone was sufficient to maintain 

 pregnant breeding ewes up to lambing time. After lambing, the addition of 

 grain to the ration proved advisjible. 



" Corn sil;ige when fed with clover hay, with grain, and with both clover 

 hay and grain, ])roved a slightly better roughage than corn stover fed with the 

 Siinie combination of grain and clover hay. Moldy or extremely sour corn 

 silage is a dangerous feed for sheep. Eleven ewes were lost in this experi- 

 ment in one week from accidentally feeding moldy silage. A ration of corn 

 silage, clover hay, and grain proved to be the most efficient means of utilizing 

 silage. 



"A ration of grain and corn stover gave very satisfactoiy results when suffi- 

 cient and pi'oi)er kinds of concentrates were used. Corn stover, clover hay, and 

 grain jirovod to be the most satisfactory method of utilizing stover. Corn 

 silage and stover both proved to bo bettor roughages than timothy hay when 

 fed with grain."

A survey of sheep and lamb production in 1914, R. M. Murphy {Tennessee 

 Sta. Bui. 110 {I'.n.',), pp. P48-26Jf, figs. 2).— This bulletin is a general discussion 

 of the sheep industry in Tennessee and includes sections on the extent of the 

 industry, causes of increase and subsequent decline, kinds of sheep and sources 

 of supply, system of management, marketing the crop, clipping and marketing 

 wool, lamb and wool clubs, dogs, needs of the sheep industry, and a suggested 

 dog law. 



Silag'e for horses and mules, E. A. Trowbridge (Missouri Sta. Circ. 72 (1914), 

 pp. 29-32, fig. 1). — ^Ten yearling mules, weighing approximately 650 lbs. each, 

 were fed for 90 days an average daily ration of 6.5 lbs. of ear corn, 8.6 lbs. of 

 mixed hay, and 4 lbs. of corn silage. The mules made a gain of only 4.8 lbs. 

 during the period. No ill results w^ere seen from the use of the silage but the 

 mules did not consume large quantities of it. This it is thought may have 

 been due to the fact that the silage was made from rather immature corn. 



Successful experiments in feeding silage to horses and mules, conducted at 

 the North Cai'olina and Pennsylvania stations ( E. S. R., 15, p. 901 ; 28, p. 172 ; 

 29, p. 773) are cited. It is advised that corn silage should always be fed in 

 combination with other feeds, and that under no circumstances should spoiled 

 silage, either moldy or rotten, be fed to horses and mules. 



Studies on the physiology of reproduction in the domestic fowl. — VIII, On 

 some physiological effects of ligation, section, or removal of the oviduct, 

 R. Pearl and Maynie R. Curtis (Jour. Expt. Zoo?., i7 (ifli.}), iYo. 3, pp. 395- 

 Jf24)- — The authors summarize the results of their studies as follows: 



" Neither the ligation, section, nor entire removal of the oviduct causes the 

 degeneration or prevents the further growth of the ovary. The pressure of the 

 inclosing funnel is evidently not necessary to ovulation since yolks are ovulated 

 into the body cavity after the ostium is sewed or ligated or after the entire duct 

 is removed. Internal pressure due to continued yolk formation is probably the 

 most important factor in the normal rupture of the follicle, since closing the 

 funnel or removing the duct apparently does not greatly delay ovulation. There 

 are cases of unoperated birds with normally functioning ovaries, and oviducts 

 apparently capable of functioning which do not produce eggs because of some 

 anatomical or physiological condition of the mouth of the oviduct which prevents 

 the entrance of the yolk.
