ANIMAL PRODUCTION. 663 



rations for the different classes of farm animals. There is included a table 

 giving the composition of farm feeding stuffs as determined by American, Eng- 

 lish, and South African analyses. 



Tomato seeds for fodder (8ci. Amer., 110 {1914), No. 15, p. 805).— "The 

 Chamber of French Connnerce at Milan announces successful attempts to pro- 

 duce a valuable cattle fodder from the tomato seeds which are a by-product 

 of the canneries. The seeds are desiccated in drying furnaces and then sifted 

 to sepai'ate them from the woody fiber of the debris. They are then crushed 

 by heated millstones and the oil which they contain in considerable quantities 

 is separated by a hydraulic press. The residue is pressed into loaves, each 

 about 2 kg. in weight. According to tests at the agricultural station at Por- 

 tici, they contain an abundance of proteids and carbohydrates." 



Commercial feeding stuffs. — Concerning feeding' practice (Vermont Sta. 

 Bui. 180 {1914), PP- iS7-252).— Analyses are reported by J. L. Hills, C. H. 

 Jones, C. G. Williamson, and G. Anderson of cottton-seed meal, linseed meal, 

 gluten feed, distillers' dried grains, brewers' dried grains, hominy feeds, buck- 

 wheat bran and middlings, rye middlings, ground oats, rj-e meal, fish scrap,- 

 meat scrap, corn meal, wheat bran, middlings, red dog floui-, alfalfa meal, 

 dried beet pulp, and various mixed and proprietary feeds. 



Genei'al instructions on balancing rations and feeding practice by A. A. Bor- 

 land and E. H. Loveland are appended. 



Inspection of feeding' stuffs {Ncic York State Sta. Bui. 386 {1914), pp. 

 315-385). — Analyses are reported of the following feeding stuffs: Cotton-seed 

 meal and feed, linseed meal, malt sprouts, distillers' dried grains, dried brewers' 

 grains, tankage, bone meal, gluten feed, gluten meal, hominy feed, alfalfa 

 meal, wheat bran, middlings, dried beet pulp, screenings, buckwheat meal, corn 

 bran, corn meal, buckwheat bran, barley middlings, beef scrap, meat meal, 

 fish scrap, pul]). screenings, buckwheat meal, and various mixed and proprietary 

 feeds. 



The testing of calculations according to Kellner's starch values in prac- 

 tical feeding in Germany, A. Sttjtzer (Internat. Inst. Agr. [Rome], Mo. Bui. 

 Agr. Intel, and Plant Diseases, 5 {1914), No. 2, pp. 155-158). — The author 

 reviews the development of the principle of starch values and comments on 

 its importance in practical feeding operations. 



In reviewing fattening experiments with oxen and pigs it is stated that 

 without exception the rations " determined according to Kellner's starch values 

 were correct, and that this method of reckoning the amount of feed required 

 was preferable to all other systems." " With regard to the feeding of milch 

 cows, there is still a difference of opinion as to what proportion of the starch 

 values must be given in the form of digestible protein." 



The mineral balance of animals, M. Hespel {Ann. Qemhloux, 24 {1914), 

 No. 4. PP- 190-213). — The author discusses the importance of calcium, phos- 

 phorus, magnesium, sulphur, sodium, potassium, and silicon to the animal body 

 and the part each plays in the various body processes. 



Metabolism during pregnancy and the lactation period, L. Dienes {Bio- 

 chem. Ztschr., 55 {1913), No. 1-2, pp. 124-133; abs. Ui Internat. Inst. Agr. 

 IRome'], Mo. Bui. Agr. Intel, and Plant Diseases, 5 {1914), No. 2, p. 231). — 

 The results of experiments are reported on the metabolism taking place in a 

 bitch during pregnancy and before and after the lactation iieriod. 



" The metabolism appears to decrease slightly in the middle of the term of 

 pregnancy, while It increases considerably during the second half of the time. 

 During lactation it is much more active than during pregnancy. During the 

 lactation period the mother and young expend the same amount of energy
