228 BETTER DAIRY FARMING 



should have a somewhat greater feeding value than oat feed, they 

 must be classed with the poorer roughages. 



411. Ground barley. — The barley kernel is covered with a 

 hull which constitutes some 15 per cent of the entire seed, in 

 comparison to the oat kernel where the hull makes up 30 per cent 

 of the whole. Barley is a rather bulky, highly digestible, low 

 protein feed, which may be used more or less interchangeably with 

 corn and oats, if it is available on the farm. It is believed that 

 for all classes of daily animals, crushed or ground barley is pref- 

 erable to whole. For milk production, tests indicate that ground 

 barley is equal to corn meal, while for feeding pigs it is also a close 

 competitor of corn. Ground barley is a useful feed for calves and 

 young stock. 



412. Feed barley. — In general barley will be found more ex- 

 pensive to purchase than a mill feed of equal value as regards total 

 digestible nutrients, such as hominy. Where barley is purchased 

 one must be careful to secure a good product since varying amounts 

 of foreign material may be present. Bylaw, ground barley must be 

 made from grain containing not less than 90 per cent pure barley. 

 "Mixed feed barley" is a term used to cover a product containing 

 not less than 75 per cent of pure barley, while "feed barley"' 

 is a name under which barley screenings may be sold. These terms 

 are very confusing, particularly as they must be distinguished 

 from barley feed and barley mixed feed, to be described later. 

 However, the only way to be sure of not being cheated is to know 

 what these various terms mean. 



413. Brewers' dried grains.— The malting of barley furnishes 

 two by-products for feed, malt sprouts and brewers' grains. The 

 latter has about 25 per cent of protein. It is bulky and its high 

 fiber content must be balanced off by using with it other feeds, low 

 in fiber. On the basis of digestible nutrients furnished, it ranks 

 somewhat above wheat bran but considerably below gluten feed. 



414. Malt sprouts. — This by-product is also a bulky feed 

 having as much digestible protein as brewers' grains, though of a 

 poorer quality. The feeding value is less than that of brewers' 

 dried grains.
