596 Feeds and Feeding. 



cent sugar were fed against fodder beets containing 19.86 per cent, 

 dry matter and 13.8 per cent sugar, or against barley. The 

 experiment included 25 pigs averaging 79 pounds each, and 

 lasted 70 days. 



The indications were that for pigs one pound of barley had a 

 feeding value equal to six to eight pounds of mangels, or four to 

 eight pounds of fodder beets. 



In experiments 1 during 1891-92, lots including 204 pigs were 

 fed four kinds of roots in addition to dairy refuse and grain. The 

 roots used were: (1) Eckendorf mangels, containing 11 per cent 

 dry matter and 6.7 per cent sugar; (2) Elvetham mangels, con- 

 taining 13.6 per cent dry matter and 8.9 per cent sugar ; (3) fod- 

 der sugar beets, containing 16.5 per cent dry matter and 10.9 

 per cent sugar; (4) sugar beets, containing 21.2 per cent, dry 

 matter and 14 per cent sugar. The lots fed barley only, made 

 the largest gain, closely followed by those half of whose grain 

 was replaced by roots in the following ratio: For 1 pound of 

 barley was substituted 7.5 pounds of Eckendorf mangels, 6.5 

 pounds of Elvetham mangels, 5 pounds of fodder beets and 4 

 pounds of sugar beets. These quantities of the different kinds of 

 roots proved nearly equivalent in feeding value. The authorities 

 conclude that about 40 per cent of the daily ration of the pig 

 may be advantageously made up of roots. The data secured at 

 slaughtering time led to the conclusion that the feeding of roots 

 to the extent practiced in these experiments produced pork of 

 a quality fully equal to that resulting from grain feeding. (320) 



900. Carrots compared with mangels. In 1892-94, 2 experi- 

 ments were conducted on nine different estates with 893 pigs, 

 divided into 175 lots. It was found in the comparative trials 

 that carrots and mangels containing equal quantities of dry mat- 

 ter had similar values in pig feeding; in other words, the amount 

 of dry matter in roots is of importance rather than the total 

 weight or the quantity of sugar contained. (317) 



901. Turnips compared with whey. When feeding barley and 

 whey to pigs, turnips were substituted for part of the whey. In 

 two experiments 3 with 30 animals, barley and whey gave an in-
