英文摘要 | For determining more economical and efficient hog raising parctices, the study on the optimum protein level of growing swine ration is necessary. This experiment was designed for the purpose mentioned above. In this experiment, thirty-two pigs were used and divied into four treated lots. The crude protein levels of mixed feed were varied with live boby weight of (I) wearing-50 kg and (II) 50-80 kg within each treatment. The (I) and (II) contented the respective crude protein levels of 18% and 16% in lot 1, 17% and 15% in lot 2, 16% and 14% in lot 3, 15% and 13% in lot 4. The results were summarized as follows: (1) From a economical point of view, mixed-feed was cost highest in lot 1, and least expensive in lot 4. This is good evidenes that the lower the protein content of mixed-feed, the lower the price is. (2) With respect to the growth rate, the mean daily gain was 0.513 kg for lot 4, 0.505 kg for lot 2, 0.500 kg for lot 3, and 0.488 kg for lot 1 respectively. The pigs in lot 1 had a greater growth rate than the other groups, but no statistical significance was observed among the treated groups. (3) In feed efficiency, although in lot 2 had a better feed utilization, only 4.759 kg of feed was needed for one kg of body weight gained, but as compared to the feeding expense, the lot 4 is most economical, at a cost of NT$15.26 for one kg weight gained. |
