In the present experiment 16 pigs averaging 142.9 lbs. were fed for 70 

 days with the following results :

The rations containing corn and com meal with tankage and buttermilk 

 proved profitable. There was little difference in the cost of the first three 

 rations, and a choice should depend upon the price of these feeds in the 

 locality and upon the conditions existing on the individual farm. There was 

 no gain in grinding corn for pigs when the price was below 50 cts. per bushel. 

 Either buttermilk or tankage was a cheaper source of protein for the pigs 

 than wheat middlings. 



Report on pig feeding experiments conducted at the college farm, Kil- 

 marnock, in 1914 and 1915, W. G. R. Paterson and L. Robe {West of Scot. 

 Agr. Col. Bui. 15 (1916), pp. 12). — The experiment was made to compare the 

 feeding of a grain ration (1) raw and dry, (2) soaked in whey and fed moist, 

 and (3) scalded with water and fed moist. The experiments were carried on 

 through two periods of 16 weeks, each using 48 pigs divided into tb^-ee lots. 



The pigs fed the grain dry made the greatest progress and most economical 

 gains. They also showed the best general appearance. The average weekly 

 gains for the pigs fed the dry ration were 7 lbs., soaked in whey 6.66 lbs., and 

 scalded 6.6 lbs., with a cost per pound of 3.3d., 4.3d., and 3.5d., respectively. In 

 a second experiment one lot was fed dry grain with one-eighth part of the grain 

 substituted by fish meal. The pigs on the dry ration gained 8.8 lbs. weekly, dry 

 ration with one-eighth fish meal 9.5 lbs., and scalded 8.3 lbs. The cost per pound 

 of gain was 3.5d., 3.3d., and 3.7d., respectively. 



Report on experiment on the feeding of pigs carried out at Calderwood 

 Estate, East Kilbride, J. Wyllie {West of Scot. Agr. Col. Bui. 77 {1916), pp. 

 79-98). — The experiment was made to test the efficacy of palm-nut cake or 

 meal in the ration for fattening pigs. 



Thirty-two pigs, one-half males and one-half females, were divided into four 

 lots. Lots 1 and 3 were fed a mixture of meals dry. Lots 2 and 4 were fed the 

 same mixture but with 4 parts of palm-nut cake added to 10 parts of the mix- 

 ture. At the end of 95 days, 8 pigs were slaughtered, and at intervals of fi-om 

 one to two weeks 8 more were killed. Lots 1 and 3 made an average daily gain 

 per head of 1.19 lbs., requiring 4.48 lbs. of grain per pound of gain. Lots 2 and 

 4 gained a daily average of 1.26 lbs. per head, using 4.62 lbs. of the feed per 

 pound of gain. The average cost of the ration per pound of gain was with lots 

 1 and 3, 4.41d., and with lots 3 and 4, 4.79d. 



Comparing lots 1 and 2 (barrows) with lots 3 and 4 (sows), the gains cost 

 5.09d and 4.11d. respectively. However, in the dressed weights the percentages 

 were enough higher with the barrows to nearly equalize the costs. 



No difficulty was found in getting the pigs to eat the palm-nut cake.
