Abstract:

This article aims to study the effect of lucid Ganoderma on the performance, egg quality, and NH3 and H2S released from feces of laying hens. Three hundred 35-week-old laying hens with good health condition and similar performance were divided into three groups randomly. There were five repetitions per group and twenty hens per repetition. The control group was fed with basic diet, and experimental groups were fed with lucid Ganoderma of a certain ratio as 0.3% and 0.6% into the basic diet. The experiment went on for 8 weeks. The results showed that: (1) the egg production rate in the 0.3% experimental group and the 0.6% experimental group was significantly higher than that in the control group (P<0.05), and the ratio of feed to egg was significantly lower than that in the control group (P<0.05), and there was no significant difference between the experimental groups (P>0.05); (2) the Haugh units in the 0.6% experimental group were significantly higher than those in the control group (P<0.05), but not significantly different from those in the 0.3% experimental group (P>0.05); the relative weight of eggshells in the 0.3% experimental group and the 0.6% experimental group were significantly higher than that in the control group (P<0.05), and the thickness of eggshells in the 0.6% experimental group was significantly higher than that in the control group and the 0.3% experimental group (P<0.05); (3) the release of NH3 from feces of the 0.3% experimental group and the 0.6% experimental group was significantly lower than that of the control group (P<0.05), which respectively decreased by 23.69% and 26.50%; the release of H2S from feces of the 0.6% experimental group was significantly lower than that of the control group (P<0.05) by 27.51%. Adding Ganoderma lucidum powder into the diet can significantly enhance the production performance of laying hens, reduce the ratio of feed to egg, improve the quality of eggs, and reduce the release of NH3 and H2S from feces.

Key words: ganoderma lucidum, laying hens, production performance, egg quality, NH3, H2S
