PLEASE HELP!! You are raising hogs for market, and your veterinarian recommends that you switch the type of feed given to the mature hogs. The vet is concerned that the present feed is too high in protein. While a high protein diet is recommended for young, growing hogs, food too high in protein can cause kidney problems in the adult animals. You switch feed and notice that the weights of your mature animals drop. You want healthy animals with maximum weight, but you do not know how to solve the problem. You design an experiment that would help you solve this problem. You think that the higher protein ration is the best way to maintain your weight gain. You have 40 hogs and you divide them into two groups. To one group, you feed the high protein feed, to the other, you feed the lower protein ration. All 40 hogs were farrowed within 10 days of each other. They are all about the same weight when you begin this experiment. Each group of 20 hogs is in the same size pen in the same barn. You weigh all hogs before the experiment, place them on feed for 3 weeks and weigh the hogs again.
