Book Description
Excerpt from A Study of the Forms of Nitrogen in Growing Pigs With Special Reference to the Influence of the Quantity of Protein Consumed The average amounts of feeds, nutrients, and energy consumed per 100 pounds live weight are given in Table 1. Effect of Rations. - The experiment lasted 174 days. During this time the differences in the general physical condition and appearance of the pigs became very noticeable. Briefly, the findings were as follows: The pigs of Lot I, the low-protein group, developed slowly, remained small, and appeared to be unthrifty and undernourished. As the experiment progressed, they became sluggish, and, toward the end of the experiment, walked with difficulty. Pig 2 became so ill that it was removed on the forty-first day and given the ration of the Station herd. It died a week later. Two of the three remaining pigs in this lot died before the close of the experiment. The kidneys of these pigs were small and in a pathological condition, showing a chronic state of parenchymatous nephritis. The remaining pig, N 0. 1, which at the beginning of the experiment was considered to be the most thrifty of the animals selected, made fair gains, averaging pound per day. However, the kidneys of this animal were found to be small and in the same pathological condition as those of the other two. The livers were small, but otherwise normal. Early in the experiment, when Pig 2 died, one pig was removed from each of Lots II and III in order to make the three lots directly comparable from the standpoint of merit of the animals, number of animals, and area per head in each pen.
