Palmnut kernel cake, J. A. Murkay {Jour. lid. Aijr. ILondon], 21 (1914), 

 No. 8, pp. 697-701}. — Metliod.s of iiiauufacturing this product are described aud 

 its composltiou aud utility value for feetling purposes discussed. It is said 

 that for feeding railch cows, palmuut kernel cake is a very good substitute 

 for liuseed cake. Cows may receive up to 5 lbs. per bead per day. 



Prolificacy of [the Guernsey] breed {Guernsey Breeders'' Jour., n. aer., 7 

 {1015), No. 2, p. 17). — It is stated that of over 3.5<X> j-early official records that 

 have been made by cows of the (iuernsey breed, 30.G per cent were made by 

 heifers with their first calves, the average production being 8.G41.91 lbs. of 

 milk and 432.28 lbs. of milk fat, with an average percentage of fat of over 5. 

 It was found that 310 cows had produced over .aGU lbs. of milk fat, and 63 

 over 700 lbs. The greater proi>ortion of these records were made after the 

 cows had carried their calves four or five mouths, which fact is brought for- 

 ward to refute any claims made against the breed regarding the fecundity of 

 the high producers. 



Comparative investigations into the performance of the breeds of cattle 

 kept in the Province of Saxony, Prussia, H. Ebbinghaus (Deut. Lundic. 

 Tierzucht, 17 {1913), Nos. JfO, pp. //7J-//76'; ///, pp. J,90-J,93; ahs. in Internat. Innt. 

 Agr. [Rome], J/o. Bui. Ayr. Intel, and Plant Discafics, 5 {191Jf), No. 1, pp. 

 99-101). — In comparing the ►Simmental with the Lowland breeds of cattle it 

 was found that with the former the live weight and gain in weight at the 

 same age are the greater, that the yearly yield of milk is lower than in the 

 Black- and Red-spotted Lowland cattle, but higher than in the Harz and cross- 

 bred animals, that the fat content and the quantity of fat produced are greater 

 than in the other breeds, and that the food consumption if expressed in Kell- 

 ner's starch-values is essentially the same as in the other breeds. The relative 

 milk yield is lower, but the milk-fat yield and increase of live weight are 

 greater than in the other breeds. 



Profitable and unprofitable cows, G. E. AVolcott {Maryland Sta. Bui. 187 

 {1914), pp. 115-13Jf. figs. 10). — From records kept for the past three yeiirs of 

 three Maryland cow-testing associations comprising more than 1.100 cows it is 

 found that " the first year's records show that there was a wide variation in 

 production between the individuals of the herd ; some made large yields, 

 while others were kept at a loss or barely paid for their feed. The records 

 for the second year prove that by disposing of low producing cows, the average 

 production of the herd was increased. In a number of herds iucrease<l pro- 

 duction was brought about by feeding the individuals of the herd according to 

 their ability to produce milk and fat. This was the case in herds where no 

 abnormally low proilucers were found. 



" The high producing cows were the most profitable. . . . 



" When the production of the individuals in the herd was known, the mem- 

 bers of the associations were able to save the heifer calves fi*om the best 

 cows. One year's record work is not sufficient. When the herd has reached 

 a high average of production constant selection is necessary to maintain this 

 average. 



" The association in Harford County .'shows a higher average production of 

 butter fat than the other associations. This is due to the fact that several large 

 herds of pure-bre<l cattle have been kept in the county for many years, and 

 the ]iure-bred bulls from those herds have been used freely." 



Testing and handling of milk and cream. R. McCann {Colorado Sta. Bui.
