32 Grain Screenings. 



Lot V, fed pulverized black seeds, refused their ration almost 

 entirely for five weeks, and at the conclusion of the experiment 

 were consuming about half the quantity fed, which portion disap- 

 peared only after very apparent effort and dislike. 



Lot VI, on equal portions of pulverized black seeds and molasses 

 meal, consumed their ration cleanly from the start, showing a strong 

 liking for it, the molasses mea apparently quite effectually neutral- 

 izing the undesirable flavour and nature of the black seeds 



Texture of Pulverized Screenings. — The nature of this by-product, 

 aside from flavour, in all its grades, was such as to render it unpala- 

 table' to sheep, the screenings being so finely pulverized as to be of 

 a dust-like consistency. This fine pulverization was necessary 

 to guard against possible spread of noxious weed seeds. No toxic 

 effect was noticed from the use of the by-product in any of its grades, 

 in fact the health of the lambs was excellent throughout, barring; 

 of course, a few isolated cases of scours, not necessarily due to the 

 nature of the ration, and easily controlled by simple remedies. 



Deductions from Experiment No. 1. — A comparison from tha 

 standpoint of greatest gains gives the following result: — 

 First. — Lot II — (Screenings; standard meal; — equal parts.) 

 Second. — Lot 1 — (Standa,rd meal.) 

 Third. — Lot IV — (Screenings, black seeds removed.) 

 Fourth. — Lot V — (Black seeds.) 

 Fifth. — Lot III — (Pulverized screenings complete.) 

 Sixth. — Lot VI — (Black seeds; molasses meal; — equal parts.) 



The order of lots as to cheapness to produce 1 pound gain is as 

 follows — 



First. — Lot V — (Black seeds.) 



Second. — Lot IV — (Screenings, black seeds removed.) 



Third. — Lot II — (Standard meal; screenings; — equal parts.) 



Fourth. — Lot III — (Complete pulverized screenings.) 



Fifth. — Lot VI — (Black seeds; molasses meal; — equal parts.) 



Sixth. — Lot I — (Standard meal) 



First. — Comparing standard meal. Lot I, with Lot II, it is seen 

 that with the valuation of other feeds in this mixture, 691 pounds 

 of complete elevator screenings has a value equal to 851 pounds 

 meal, 259 pounds hay, and 1025 pounds roots, or: $39 per ton. 



Second. — Comparing Lot I and Lot III, it is seen that 1,442 pounds 

 standard meal equal 1,248 pounds screenings, 735 pounds hay, 

 and 1500 pounds roots, at valuation of $£8 per ton. 



rnvd.— Comparing Lot I and Lot IV, it is seen that 1,298 pounds 

 screenings, black seeds removed, is equivalent to 1,442 pounds meal; 

 105 pounds hay, and 2516 pounds roots, or $36 per ton. 



Note. — From these deductions where complete screeriings are 

 shown to be worth $26 and screenings, black seeds removed, worth 

 $36, the value of the removal of black seeds is apparent. 



FoMr^A.— Comparing Lots III and IV it is seen that 1,298 pounds 

 screenings with black seeds removed is equivalent to 1,248 pounds
