44 64 Pen No. 1, a pure bred Suffolk; age, 4 months. Pig No. 10 was the same as No. 12 of the experiments of 1870. These pigs (Nos. 10, 14, and 16) in the experiment of 1870, "did not fatten, but made their increase in weight in bone and muscle." "At the termination of the experiment (1870), as they were only in fair store condition, they were turned out of the pens, and kept for experiment when they were a year older." Pigs Nos. 7 and 9 were purchased with the same lot as Nos. 10, 14, and 16. They were all large-framed, coarse hogs, with a cross apparently of Chester White. Pigs Nos. 11, 4, 6, 8 were finer boned and better formed, with less heads and legs. They were apparently a grade of Suffolk, or some other small variety. As in the previous experiments, the pigs were weighed at the beginning of each week, before feeding, and their ration of unbolted corn meal (their exclusive feed) was weighed out at the time of feeding. Care was also taken to give each pig all the meal it would readily consume, the amount of each feed being regulated by the appetite of the animal, so that no waste could take place by leaving a portion of the ration in the trough." The weight of each pig, at the beginning of the experiment and at the close of each week, together with the total gain and total gain per cent., is given in Table No. 1. The weights in all of the Tables are given in pounds and decimals of a pound. TABLE NO. 1.

In Table No. 3 is given the average weight of each pig for each week of the experiment. TABLE No. 3. Average Weight of cach Pig for each Week of the Experiment. The relation of feed consumed to the weight of the animal is shown in Table No. 4, which gives the amount of feed con sumed per week in each pen for each 100 pounds of live weight. TABLE No. 4. Meal Consumed per Week for each 100 pounds of Live Weight. The gain in live weight made in each pen for each week of the experiment is shown in Table No. 5. A loss in weight is indicated by the minus sign. 18.16 15.40 14.12 17.43 14.69 17.94 15 66 17.04 16.80 16.44 16.80 14.89 17.08 14.76 11.73 16.24 12.47 16.28 10.42 15.56 13.40 15.71 15.25 7.50 15.45 12.70 13.71 11.71 |
