cured into hay, they are said to furnish a feed fully equal in feeding 

 value, although not in palatability, to meadow hay (or similar to 

 grain hay or stock hay). Potato vines may also be made into silage 

 by being placed in a silo or a trench in the field, as in the case of 

 beet tops. Such silage makes a more palatable feed for stock than 

 the dried tops. 



Orchard Products.^ Apples, grapes, oranges, and other orchard 

 fruits are frequently fed to stock, especially swine, in fruit-growing 

 sections. Broadly speaking, their feeding value varies from one- 

 fourth to one-sixth of that of common grain feeds. The by-products 

 obtained in the manufacture of apple cider, wine, olive oil, etc., have 

 a distinct feeding value, as indicated by the analyses given in the 

 table, and should be utilized for stock feeding, if possible, being 

 especially adapted for feeding market hogs. Raisins that are not 

 marketable will make an excellent feed for fattening hogs if they do 

 not make up over one-half of the grain ration ; fed more heavily, they 

 arc- likely to cause scouring and will produce unsatisfactory gains. 

 According to experiments conducted at the University Farm, raisins 

 fed as stated possess a similar feeding value as barley, pound for 

 pound. The same holds true in the case of carob pods, the fruit of 

 the carob tree. This grows readily in the southern part of the state, 

 giving annually when fully established a crop of pods which are 

 greatly relished by stock on account of their high sugar content. 

 Rolled pods are especially valuable as a component of grain mixtures 

 for calves. Almond hulls are only of value for feeding hogs and 

 sheep on account of the nuts present therein. If the huller has done 

 poor work, hogs will gain weight on rooting over a pile of almond 

 hulls. Otherwise, this will not furnish sufficient nutriment to main- 

 tain the animals at an even body weight. 



Acorns are used in parts of the state as a feed for fattening hogs. 

 According to the testimony of packers and butchers, the quality of 

 acorn-fed pork is, however, very inferior, and their use cannot be 

 recommended except when fed with at least an equal amount of grain. 

 The quality of the pork produced is soft and undesirable from both 

 the packer's and consumer's standpoint, even if grain (barley) is 

 fed for several weeks prior to slaughter. 



Spineless cactus is included in the preceding list of feeds, mainly 

 because of the interest which has been created regarding it through 

 occasional favorable newspaper reports. A single trial with cows in 

 the University dairy herd showed it to have no more merit than sug-
