available, for it does away with the necessity of sorting into many groups, 

 with the consequent falling off in the reliability of the averages obtained." 



The analysis of the data on fattening baby beef animals indicates that " for 

 the herds considered, the cost of producing the calves and carrying them until 

 weaning time was by far the most important factor in determining the profit. 

 There was no connection between the cost at weaning time and any of the 

 other factors, for the calves which were produced cheaply were seemingly just 

 as good feeders and brought just as good a price per pound as the more 

 expensive ones. The weight at which the calves were sold and the date of sale 

 had very little effect on the profit, except for the fact that in the two years 

 of the records the price was higher in the latter part of the summer, at the 

 time when the heavier calves were put on the market. The calves which con- 

 sumed the heaviest ration sold at higher prices than the others, but did not 

 return a correspondingly greater profit, as the advanced price scarcely offset 

 the extra value of feed consumed."

[Feeding experiments with pigs in Minnesota] (Minnesota Sta. Rpt. 1916, 

 pp. 45, 72). — In a comparison of hand feeding with self feeding, 100 pigs in 

 ten lots were fed solely on grain rations consisting of various mixtures of 

 shelled corn, shorts, tankage, ground barley, and linseed meal. In every case 

 the self-fed pigs made larger daily gains than those fed twice daily by hand. 



Rape pasture supplemented with 2, 3. and 4 per cent shelled-corn rations 

 gave average daily gains per pig of 0.fil, 0.81, and 0.93 lbs., respectively. Valu- 

 ing corn at 75 cts. a bushel, and pasture at $10 an acre, the actual feed cost per 

 pound of gain was 4.6, 4.46, and 4.81 cts., respectively. 



Results at the Crookston substation are noted on page 268 and below. 



The fall litter of pigs, W. Dietrich (ilinne.^ota Sta., Rpt. CrookMon Substa., 

 1910-1916, pp. 93-95; .Minnesota Sta. Rpt. 1916, p. 72). — Suggestions are given 

 for the successful raising of fall pigs under northern Minnesota conditions. 



Twelve pigs born about September 1, 1915, were weaned and put on feed 

 November 22 and fed until the follo\\ing May. The rations consisted of barley, 

 oats, and tankage, to which corn was added at the beginning of the eleventh 

 week, and a little rye during the last week of the test. 



In addition to the above feeds and water these pigs had a small quantity of 

 a 1 per cent solution of concentrated lye, and were also given access to ground 

 limestone and bone meal. At eight months these pigs averaged 255 lbs. each. 

 They required 5.42 lbs. of feed per pound of gain. 



[Clover pasture for hogs] (Minnesota Sta., Rpt. Duluth Substa., 1915, pp. 

 S, 6). — In a feeding test with three sows during July and Augiist, It was 

 found that dry brood sows may be maintained on good clover pasture with 

 practically no grain if they are mature, but that a light grain ration is desir- 

 able if they are growing.
