ANIMAL PBODUCTION. 569 



Swine investigations, F. C. Minki.kk (Xciv Jcrsfi/ sia. Rpt. 1913, pp. Itil- 

 199, pis. 5; Circ. 40 {W14), pp. 3-21, pis. 5).— This treats of the breeding, feed- 

 ing, care, and nianagomeuv of swine under New Jersey conditions. 



In trials to determine the adaptability of alfalfa for pasturing and growing 

 swine, it was found that 2i acres of alfalfa, not in average condition, furnished 

 forage for 10 head of brood sows and 79 pigs from May 1 to October 1. The 

 sows suckling pigs were fed in addition a ration made up as follows: Corn 

 meal, 100 lbs.; tankage, 12; wheat bran. 10; and oil meal. 4. The pigs were fed 

 limited quantities of skim milk and started on a grain mixture of I'ed dog 

 flour. 100 lbs.; crushed oats. 100; and tankage, 10. with a small quantity of 

 soaked shelled corn. The sows gained slightly in total weight during the sea- 

 son, while the pigs aA'eraged gains of 1.12 lbs. per day from birth until removed 

 to the fattening i)ens. Without allowing for tlie hay harvested, the mainte- 

 nance of the 10 brood sows, and deducting the cost of grain and value of the 

 milk fed, the alfalfa was responsible for approximately 460 lbs. of pork per 

 acre. 



Two lots of 7 14S-lb. fall shouts each were fed for 30 days beginning May 1 

 as follows: Lot 1. corn meal and steamed kidney-bean meal, with alfalfa pas- 

 ture; lot 2, corn meal and bean meal, with skim milk. Lot 1 made an average 

 daily gain per head of 1.63 lbs., lot 2, 1.14. The cost per pound of gain was. 

 for lot 1, 4.3 cts., for lot 2, 7.1 cts. Ou this basis the forage value of the 

 alfalfa eaten was estimateil to be $21 per acre per month. The alfalfa-fed 

 pigs, which were in a later experiment confined in a dry pen, continued to 

 make more rapid gains than those of lot 2. 



Ten 112-lb. pigs were turned into a half-acre of corn to hog down. They 

 cleaned up the plat in 16 days, making an average daily gain per head of 2.27 

 lbs. Kape and red clover had previously been seeded in the corn and furnished 

 forage for the iJigs. On this basis the corn was estimated to be worth $68.20 

 per acre. 



Six lots of 2 pigs each, weighing approximately 200 lbs., were selected for 

 use in an exiieriment to determine the palatability and feed value of the refuse 

 product known as garbage tankage. They were fed for 40 days as follows : 

 Lot 1, corn meal and skim milk, 10:25; lot 2, corn meal, molasses, and skim 

 milk, 6:5:25; lot 3, corn meal, molasses, and garbage tankage. 4:2:9; lot 4, 

 corn meal, garbage tankage, and skim jnilk, 4 : 9 : IS; lot 5, corn meal, molasses, 

 garbage tankage, and skim milk, 4 : 2 : 9 : 18 ; and lot 6, corn meal, garbage tank- 

 age, and molas.ses, 4:8:3. It was necessary to neutralize the acid condition 

 found in the garbage tankage by means of bicarbonate of soda or lime water. 

 The average daily gains per head for the respective lots were 1,72 and 1.5, 

 1.37 and 1.57, 1.37 and 1.57, 1.1 and 2, 1.4 and 1.72. and 1.65 and 1.64 lbs. ; the 

 cost per pound of gain, 7.7, 7.5, 4.2, 5.7, 5.6, and 3.5 cts. The garbage tankage 

 product analyzed as follows: Moisture. 61 per cent, protein. 8.13; carbohydrates. 

 25.00; and ash, 5.S1. Eations for swine are suggested. 



Swine-feeding experiments with heated and unheated skim milk and with 

 dried yeast, Klein {ililchw. Zenlbl, J,3 {WW, No. U, pp. 3St-38.',) .—In these 

 experiments with 7-week-old pigs it was demonstrated that heated skim milk 

 fed in addition to potato flakes and barley bran slightly increased the daily 

 gains during a 12-week period over pigs feil unheated milk, while with pigs 

 fed a similar ration, but in which a portion of the unheated milk was replaced 

 by dried yeast, the daily gains were materially lower. 



Fattening pigs on cassava, A. GoriN and P. Andouard {BiiI. Soc. Nat. Agr. 

 France, llf (191^), No. 4, pp. 481-483). — It was demonstrated that in the case 

 of pigs fed milk in addition to cassava it took only 3 lbs. of cassava to produce
