本试验研究了腐植酸对产蛋鸡采食量、产蛋量、饲料转化率、蛋重及蛋内外品质的影响。本试验共使用180只（海塞克斯褐）蛋鸡（36周龄）。试验设1个对照组和2个试验组，每组60只母鸡，4个亚组。实验期为16周。试验结束时，添加腐植酸对饲料消耗量和饲料效率有显著影响。当腐植酸添加量为30 g/t和60 g/t时，产蛋量分别提高了91.70%和91.32%。蛋壳厚度、蛋壳破裂强度、蛋黄指数、蛋白指数和哈夫单位在各组间差异不显著。因此，可以得出结论，在日粮中添加30和60 g/t饲料的腐植酸可以用于提高产蛋量、蛋重和饲料效率。
The effects of humic acid on feed consumption, egg production, feed efficiency, egg weight and external and internal egg quality of laying hens were studied during feeding periods. A total of 180 (Hysex Brown) layers (36 weeks of age) were used in this experiment. There was one control and two experimental groups, each containing 60 hens and 4 subgroups. The experimental period lasted 16 weeks. At the end of the experiment, the supplementation of humic acid had a significant effect on feed consumption and feed efficiency. An increase in egg production was determined when humic acid was added to the diets at 30 g/t of feeds (91.70%) and 60 g/t of feeds (91.32%). There were no significant differences between the groups in egg shell thickness, egg shell breaking strength, yolk index, albumen index and Haugh unit. It can be therefore concluded that the dietary supplementation of humic acid at doses of 30 and 60 g/t feed can be used to improve egg production, egg weight and feed efficiency.
