In order to learn the proportion of grain which passed through the 

 pigs undigested the whole grains in three samples (weighing 5 oz. each) 

 from the feces of each lot of pigs were counted. On an average the 5 

 oz. of manure from the lot fed corn contained 7 whole grains; from the 

 lot fed dry wheat 1,107 grains; from the lot fed corn and wheat G85 

 kernels of corn and 12 of wheat, and from the lot fed soaked wheat 

 1,003 grains. The conclusion is drawn that wheat should be crushed or 

 broken before feeding. A trial showed that 4 per cent of the wheat 

 kernels from the feces of the lot fed dry wheat germinated. [None of 

 the undigested grains from the lot fed soaked wheat germinated. 



A test was made of the strength of the bones of the pigs in each lot. 



" Generally .speaking, the result of these tests shows that the hones of the corn-fed 

 lot crushed most readily, while those of the soaked-wheat lot crushed least readily. 

 The principal feature of interest was that the hones of the corn-fed pigs seemed 

 appreciably softer than those of the other three lots." 



The organs and flesh of the different lots were weighed and examined, 

 but no marked differences were observed. 



Montana swine feeding, F. Beach {Montana Sta.Bul. 14, pp. 19-33, 

 pis. 2). — A test was made with pigs to learn the value of alfalfa and of 

 stubble fields for pasture and to compare barley with different mixtures 

 of barley, wheat, and peas. On August 22, 9 brood sows (averaging 

 272.3 lbs.) and 41 pigs (averaging 57.1 lbs.) were turned on an alfalfa 

 pasture of 4£ acres. The pigs were from 2 to 5 months old. They re- 

 ceived 1 lb. of cracked barley per head daily, and were fed in a pen 

 which was so arranged that they could pass in and out. The sows 

 could not enter the pen and received no food in addition to the pasture. 

 At the end of G weeks the sows on an average had gained 5 lbs. in 

 weight. In 2 weeks the pigs made an average gain of 4.5 lbs. per week. 

 Three pigs (boars) were then removed. In the 5 weeks following the 

 remaining pigs made an average gain of 0.42 lb. per head daily. They 

 were then turned into barley, wheat, and pea stubble fields of IS acres, 

 10.44 acres, and 10.73 acres, respectively. They were not fed grain in 

 addition to what they could find in the fields, except on stormy days, the 

 grain thus fed amounting to 24.1 lbs. in 5 weeks. During this time the 

 pigs made a gain of 22.8 lbs. per head, or 17.5 lbs. deducting the amount
