为研究不同硒水平对淮南麻鸭生长性能及屠体性状的影响,选择144只1日龄健康且体质量相近的淮南麻鸭,随机分为4组,每组6个重复,每个重复6只鸭。Ⅰ组为对照组,饲喂基础饲粮;Ⅱ、Ⅲ、Ⅳ组为试验组,分别饲喂添加0.1、0.2、0.3 mg /kg亚硒酸钠的基础饲粮,试验期9周。结果表明:与Ⅰ组相比,Ⅱ、Ⅲ、Ⅳ组9周龄淮南麻鸭的体质量分别极显著提高了6.39%、12.21%、7.34%,Ⅱ、Ⅲ、Ⅳ组的日增质量比Ⅰ组极显著提高了6.41%、12.23%、7.35%,但Ⅱ组与Ⅳ组之间差异不显著;与Ⅰ组相比,Ⅱ、Ⅲ、Ⅳ组的料重比分别极显著降低了5.97%、11.64%、6.92%,且Ⅲ组料重比最低;Ⅱ、Ⅲ、Ⅳ组的采食量与Ⅰ组之间差异不显著;Ⅱ、Ⅲ...

Researches on selenium influnce upon the growth of rice and its accumulation of selenium have been made by means of the combination of soil cultured and hydrophically grown in pots with selenium provided at different levels in the form of Na2SeO3. The results are as follows. The proper application of selenium in moderate amounts to rice advances its growth,strengthens the reduction of the roots, promotes the tillering, increases the yield and raises the selenium content of the seeds. The resistance to selenium of rice is related to its grow...
