The cost of producing' beef in winter, K. .7. .T. .Mackknzik (Jour. fill. Ar/i: 

 [I.ondon], 15 (t'JOS), No. //, pp. 2od-260). — A discussiou of results previously 

 noted (E. S. R., 10, p. 773; IS, y,. (JOG). 



Feeding experiments with mature oxen and sheep (Landw. Wchtischr. 

 Sdcliurn, 10 {190S), No. 38, pp. 3,i2, 33S). — A ration low in protein fed to 8 oxen 

 for 3 months showed a total gain of 900 lbs., as compared to a similar gain of 

 72() lbs. on a ration high in protein. In the latter ration there was an actual 

 loss of GO lbs. during the last 20 days of the experiment. When similar I'ations 

 were fed to sheep, however, there was a total gain of 1,014 lbs. at a cost of 

 s.O cts. per pound on the ration poor in protein, and a similar gain of 1,2G8 

 lbs. at a cost of 7.8 cts. per pound on the ration rich in protein. 



Breeding sheep for mutton, G. M. McKkown (Affi: (la:;. N. »S. Wales, 19 

 (1908), No. 6, pp. 489-^96, figs. 6). — Various crosses have been tried to ascertain 

 the most profitable sheep for the small land owner in New South Wales. A 

 lamb that can be sold at 4 or 5 months of age is desired, and so far the best 

 results have been obtained from a Shroi)shire ram and a Lincoln-merino ewe. 

 The author discusses the best crojjs for nnitton production. 



Sheep raising for the production of wool in western Africa, Y. Hknry (Agr. 

 Prat. Pays Chauds, 8 (1908), No. U(J, pp. 182-192, figs. £?).— Methods of raising 

 sheep and marketing wool as practiced in the Soudan are described. 



Goats (Jour. Jamaica Agr. Soc, 12 (1908), Nos. 4, pp. 102-10-',; 10, pp. 337- 

 S'lO). — The tyi^es of goats kept on the island are the Maltese, Anglo-Nubian, and 

 Swls.s-Toggenburg for milk, the common Jamaica goat for nuitton, and the 

 Angora f<n' mutton and hair. The keejting of pedigreed animals for milk and 

 mutton is advocated. The subjects of breeding and management are discussetl. 



The value of potatoes for pig feeding in rations with different protein 

 content, O. Kellner et al. (Bericht des Drutschrn Landivirtschaftsrats an 

 das licichsamt dcs Innern bctreffend Mdstungsrcrsuclte tnit Hchweincti iibcr die 

 Vcnccrtung dcr Kartoffcln hei Verschiedcner Eiweisszufuhr. A. AUgemcinvr 

 lirricht, pp. 32; li. lierichte iihrr die Einzelnrn Vcrsuchc, ,tiK 2I'>. Berlin, 

 190S). — That potatoes are the best home-grown substance for ]iig feeding 

 is rejiortt'd as the result of a cooperativi' series of experiments carried on 

 at 17 different stations under the direction of the (Jerman Agricultural Society 

 til estimate the value (»f potatoes when fed in varying i»roporti(»n with sup- 

 lilemeutary jirotein fewls. Skim milk, meat meal, tish meal, bran of grains, 

 husks of fruits, and oil cake were the su|)plements used. Tlie normal ration 

 liropo.sed was G.2 kg. i)rotein per 1,000 kg. live weight for pigs weighing 20 kg., 

 but tlie proi)ortion of jtrotein was decrea.sed as the animals grew older, so that 

 when animals had reached l.'JO kg. in weight they would receive for the normal 

 ration rmly 2.4 kg. jtrotein iier 1,(MM) kg. live weight. 



'I'lie experiments showed that steamed potatoes were au excellent food for 

 fattening swine, this agreeing with practical exp«'rience. It is staled that po- 

 tatoes can compose HO to GO per cent of the digestible carbohydrates of the 

 ration and in .some cases even more. An increa.se of |)rotein above tfie normal 

 amount was found to l)e of no advantage, a large increase iiroducing lameness. 

 .\ dtH-rease of 1") to 20 iwr cent of normal i)rotein diminished the live weight 

 and increaswl the amount of carbohydrates consumed, yet where a slow fatten- 

 ing with clieaii f I^* if< desire<l it is l)elieved tliat a slight (Um rease in protein 



may be allowed.
