34 Gkain Screenings. 



Deductions from Experiment No. II. — In reviewing the results of 

 this experiment the deductions afforded by Experiment I should be 

 remembered. The order of the lots from standpoint of total gains is 

 as follows : — 



First.— Lot V— (Black Seeds.) 



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



Third. — Lots III— (Complete screenings.) 



Fourth. — Lot I — (Standard ration.) 



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



Sixth. — Lot II^-(Screenings; regular meal; ee[ual parts.) 



Lots V, VI, and III, receiving black seeds in Experiment No. I 

 in various percentages, apparently reached their limit of production 

 on a roughage diet supplemented by inferior meal, and in consequence, 

 were able to show marked gains on a superior ration. The lambs of 

 Lot I having grown and improved in condition generally, during the 

 regular experiment, were also in a position to make fair gains during 

 the finishing period, while the lambs in Lots IV and II which had 

 received the most desirable screenings rations previously, now stand 

 fifth and sixth respectively. 



This period, therefore, while primarily intended to give a uniform 

 fiELish to the lambs, further bears witness to the fact that the lambs 

 fed black seeds were held back during the experiment, as 

 evidenced by their very rapid comparative gains during the fin- 

 ishing period. In spite of the fact that many of the lambs dur- 

 ing Experiment No. I were fed meal rations known to be unpala- 

 table, and probably actually harmful, yet, due to the finishing period,' 

 these lambs in April sold for top price on the Toronto market. 



SUMMARY OF FEEDING EXPERIMENTS. 



Black seeds. — 1. In all experiments the black seeds were pulver- 

 ized finely. This was a costly operation and may have detracted 

 from the acceptableness for sheep, but was absolutely necessary to 

 prevent the distribution of weeds through the manure. Any possible 

 food value of black seeds is overcome by the cost of grincnng. 



2. Black seeds for sheep are very unpalatable whether fed alone 

 or in the complete screenings. 



3. Black seeds, however fed, are detrimental. "When made pala- 

 table with an addition of molasses it is clearly proven that the 

 greater the quantities consumed, the less gain and profits result, 



4. Black seeds for swine are very unpalatable, however fed. In 

 all experiments they showed little or no food value and often detracted 

 from the value of the other constituents in the ration. Palatability 

 is the secret of pig feeding, and black seeds will spoil a tasty ration. 



5. Black seeds for dairy cows are very unpalatable whether fed 

 alone or in the complete screenings. When compelled to eat a small 

 quantity, the cows fall off in milk. It is safe to say that cows will 

 produce more on two-thirds of their regular meal than when they 

 receive the full quantity of meal, composed of one-third black seeds.
