The Effect of Thyroprotein Supplementation of the Ration Upon the Performance of Early-Weaned Pigs.
Twenty-four early-weaned pigs were fed three different rations, with and without the addition of 16 mg. iodinated casein/lb. feed. In general, supplementation did not result in any change in liveweight gain, feed intake or feed efficiency, but brought about a noticeable, though not statistically significant, increase in the apparent digestibility of dry matter, gross energy, crude protein, ether extract, and total carbohydrates. An examination of the results of supplementing individual rations revealed that in one case iodinated casein had adversely affected liveweight gain, feed intake and efficiency of feed conversion. This particular ration, in comparison with the other two feeds, contained a high level of soybean oilmeal and a low level of feed of animal origin.
