[On the sheep-carrying capacity of the Boseworthy Agricultural College 

 farm], A. J. Perkins (Jour. Dept. Agr. So. Aust., 17 (1913), No. S, pp. S64-390, 

 figs. 4), — This article reports work covering a period of 7 years. The total 

 average acreage of grazing crops on this farm was 149.1 acres and of ordinary 

 pasture 312.2 acres, making a total of 461.3 acres in pasture; and under culti- 

 vation 1,072.9 acres, making a total of 1,534.2 acres in total arable-grazing land. 

 The yearly average number of sheep raised was 1,370 or 0.89 sheep per acre 

 of arable-grazing land, and 2.97 sheep per grazing acre. 



The feeding stuffs fed to 1,254 head of sheep during 1912-13 (a period largely 

 of hand-feeding) were as follows: Bran 2,766 bu., crushed com 5,550 lbs., pol- 

 lard 24 bu., hay chaff 11% tons, straw chaff 19i tons, baled straw 1,500 lbs., 

 molasses 500 Ibs.^ costing in all £279 5d., or about $1.11 per head. 



The sheep-carrying capacity for the ordinary pasture (fields temporarily out 

 of cultivation) averaged 1.51 head per acre; for stubble fields during 4 months, 

 December to March, 1.55; for fallow grazing, September to December, 0.66; 

 and for the forage crops: Rape, June to January, 2.79; kale, September to 

 January, 5.87; turnips, September to December, 7.27; vetch, September to De- 

 cember, 6.74; peas, September to March, 4.03; lucern, 12 months, 1.35; and 

 sown grasses, consisting of rye grass, cocksfoot, Kentucky blue grass, prairie 

 grass, and sulla, 1.55 head per acre. 



The growing and fattening of hogs in the dry lot and on forage crops, 

 E. S. Good (Kentucky Sta. Bui. 175 (1918), pp. Sll-356, figs. 10).— The results 

 of experiments reported in part 1, which treats of the growing and fattening 

 of hogs in the dry lot, demonstrated that with one lot of 39-lb. pigs a gain of 

 but 25 lbs. per head in 196 days was secured on corn alone in a dry lot and at 

 a cost of 17.8 cts. per pound, whereas the same pigs were made to gain 212 lbs. 

 per head in the next 155 days by supplementing the corn meal with shipstufif, 

 green alfalfa, and alfalfa hay at a cost of 5.3 cts. per pound. Forty-pound pigs 

 gained 263 lbs. per head in 223 days at a cost of 5.9 cts. per pound gain by the 

 feeding of middlings, with a small amount of tankage and oil meal for the first 

 75 days, when the oil meal and tankage were discontinued and com meal intro- 

 duced and fed in increasing amounts until at 195 days the pigs were receiving 

 corn meal and middlings 1 : 1, with corn meal alone for the final 4 weeks. Ship- 

 stuff and middlings compared favorably when fed with corn meal to pigs. 



Four lots of pigs weighing approximately 64 lbs., fed during a 125-day feed- 

 ing period as follows: Lot 1 corn meal, lot 2 corn meal, green alfalfa, and al- 

 falfa hay, lot 3 corn meal and soy-bean meal 7 : 1, and lot 4 corn meal and tank- 

 age 7 : 1, made 86, 142, 139, and 159 lbs. gain per head, costing 6.39, 5.3, 4.79, 

 and 4.8 cts. per pound of gain. 



Three lots of 10 hogs each, weighing about 143 lbs. each, and fed 56 days as 

 follows : Lot 1 corn meal alone, lot 2 corn meal and soy-bean meal 10 : 1, lot 3 

 corn meal and tankage 14 : 1, made 76, 84, and 93 lbs. gain per head, costing 

 5.82, 5.42, and 5.07 cts. per pound of gain, respectively. Comparing the 39-, 64-, 

 and 143-lb. pigs fed corn meal alone it is noted that this becomes a more 

 balanced and economical feed for a hog as he matures, but that in all cases the 

 addition of a nitrogenous supplement such as green alfalfa, alfalfa hay, and 

 soy beans increases the economy of gains. 



The average gain made per bushel by all lots of hogs receiving corn meal 

 alone in these dry lot experiments was 8.3 lbs. and by lots receiving a nitroge- 

 nous supplement 12.92 lbs. 



Runts fed a balanced ration made economical, but small gains. The greatest 

 drawback in the feeding of runts proved to be their slow growing qualities. 



Ground wheat, used as a sole ration for pigs averaging 61 lbs. and fed 125 

 days produced 40 per cent larger gains than corn meal alone fed to a similar lot.
