This lot of succotash was foraged off by sixteen young pigs turned in on June 

 20th, at a weight of 1,208 pounds; they foraged on the lot thirty-two days, receiv- 

 ing at the same time some supplementary grain food. Illustration No. 3 shows 

 some of the pigs foraging. As this was the first of a series of experiments with 

 three different classes of hogs, the detailed results will be given later. Where 

 this crop was grazed off, the rape plants were bitten off so close to the ground 

 that they failed to grow again. On another lot, however, grown in exactly the 

 same way but cut and used as a soiling crop for dairy cows, the rape made a 

 second growth which some six or eight weeks later was about knee high. This 

 mixture proved to be an excellent one for dairy cows; the small amount of rape 

 present in first cutting, did not appear to effect the milk at all, while the peas 

 furnished considerable of the much needed protein. 



Through the courtesy of F. W. Robison, Station Chemist, we received the fol- 

 lowing results of the analysis of the 1904 succotash mixture with the results ex- 

 pressed on "dry air" samples as follows, viz.. 



Moisture 8.30% 



Ash 10 . 35% 



Protein (total nitrogen) 15.09% 



Proteids (true) 14.30% 



Amido bodies 79% 



Ether extract 5 . 45% 



Crude fiber 27.01% 



Carbohydrates (not fiber) 33.8% 



The sample analyzed consisted of the remixed materials shown in the Illustration 

 No. 2. 



Peas and Oats as Forage for Sivine, 1003 and 190.'/. — In some localities peas are 

 quite commonly grown until they nearly reach maturity, when hogs are turned 

 in to feed upon the grain and such of the forage as they may desire. Our tests 

 of 1903 and 1904, to determine the feeding value of this forage crop for hogs, 

 gave the following results, viz.: 



Test of 1!)03. — On May 9th, 1903, lot 3 Fig. 12 was sown to a mixture consisting 

 of peas three parts, and oats one part, by measure, at the rate of 2% bushels per 

 acre, a seed drill being used. Oats were used along with the peas to hold them 

 up off the ground and prevent mildew. On August 14, 1903, when the peas were 

 just past the cooking stage, seven pigs weighing 780 pounds were turned in the 

 lot to forage. By September 10th, the peas, most of the oats and some forage, 

 had been consumed and the pigs had received no other food though water was 

 regularly supplied. On this date the hogs were removed at a weight of 850 pounds. 

 This one-third acre of peas and oats, therefore maintained 780 pounds live hogs 

 27 days and produced a gain of 70 pounds. At this rate one acre would maintaim 

 2,340 pounds live hogs 27 days and produce 210 pounds pork. 



Test of 100. 'i. — In a manner like unto that just described, peas and oats were 

 grown in lot 2 Fig 12, in 1904, which had produced succotash in 1903. The mixture 

 ■was sown May 7, 1904, and seven hogs weighing 1,321 pounds were turned ia 

 August 4th with the grains at about the same stage as the preceding year. On 

 August 17th, after thirteen days, these hogs were removed weighing 1.376 5 pounds, 

 making a gain of 55.5 pounds. This one-third acre of peas and oats, therefore, 

 maintained 1,321 pounds of live hogs thirteen days and produced a gain of 55.5 

 pounds. At this rate one acre would maintain 3,963 pounds live hogs thirteea 

 days and produce 166.5 pounds gain. 



These two tests were conducted under exactly the same conditions. Both years 

 the growth of pea vines was excessively heavy at the expense of grain production, 

 due, largely, to the exceeding richness of the soil on which the crop was grown, 

 and the very wet season. Some of the oats were apparently smothered but suf- 

 ficint grew to hold the peas up fairly well; these oats matured and were not quite 

 all gleaned by the pigs as shown by the appearance of a vigorous volunteer crop 

 later in the season. No peas were left, however. These results in pounds of 

 pork are considerably less than we should expect from an acre of peas, proriucina: 

 twenty bushels of gi'ain and the small gain is no doubt due to the soil and 

 climatic conditions which stimulated vine and leaf growth at the expense of the 

 grain.
