period they received the late-cut silage they produced 0.75 Ih. more raillc 

 containing 0.025 It), more butter fat per day per cow than when fed the early- 

 cut silage. ... It is impossible to draw definite and guiding conclusions 

 as to the proper stage of maturity for cutting sunflowers from this one experi- 

 ment." 



Six cows were used in a comparison of chopped green sunflowers and chopped 

 green corn as supplements to pasture through two 28-day periods. During sun- 

 flower feeding the cows maintained their weight better than during corn feed- 

 ing (when one cow went ofl' feed), consiuned somewhat more feed, and gave 

 slightly more milk, and it is concluded that " chopped green sunflowers 30 to 

 40 per cent in bloom were equal to chopped green corn in the roasting ear 

 stage as a soiling crop for dairy cows." 



A comparison of sunflower silage and alfalfa hay in the winter ration of 

 breeding ewes and a similar comparison (preliminary) with brood sows indi- 

 cated in both cases that 2.5 lbs. of the silage is equivalent to 1 lb. of the hay. 

 The approximate daily ration of a pregnant ewe during sunflower feeding 

 consisted of 3 lbs. of alfalfa hay, 2.2 lbs. of the silage, and 0.2 lb. of oats. 

 " No unfavorable results were obtained from feeding the silage to breeding 

 ewes either before, during, or after lambing." 



Four samples of sunflower silage taken at different depths had the follow- 

 ing percentage composition : Crude protein 2.1, ether extract 0.5, crude fiber 

 6.8, other nitrogen-free extract 10.4, and ash 1.6. A digestion trial by W. B. 

 Joseph and M. .T. Blish (to be reported in detail later) indicated 1.24 lbs. 

 digestible protein, 0.37 lb. digestible fat, and 10.13 lbs. digestible carbohydrate 

 (including fiber), in 100 lbs. of the silage.

 (New Jersey Stas. Bui. 336 {1919), pp. 5-60).— The report is made on 840 

 samples of feeding stuffs collected under the State law in 1919. Data as to 

 the moisture, protein, fat and fiber content of the following products are given : 

 Alfalfa meal, brewers' dried grains, yeast dried grains, malt sprouts, barley 

 mixed feed, barley flour, buckwheat feed, buckwheat middlings, buckwheat offal, 

 coconut oil meal, cottonseed feed, cottonseed meal, corn feed meal, corn gluten 

 feed, corn gluten meal, corn and cob meal, hominy feed, corn and oats, dried 

 beet pulp, linseed meal, peanut oil meal, rye bran, rye middlings, wheat bran, 

 wheat feeding flour, wheat mixed feed, wheat middlings, wheat and rye mid- 

 dlings, and various proprietary mixed feeds, calf meals, and poultry feeds. The 

 moisture, protein, fat, and phosphoric acid in samples of meat .scrap, crack- 

 lings, and digester tankage are also reported. The prices of 17 feeding stuffs 

 in 1919 and in the three preceding years are tabulated.
