The present study was conducted to investigate the comparative effects of organic and inorganic forms of sulfur, methyl sulfonyl methane (MSM) and sodium sulfate (SS), on laying performance, egg quality, ileal morphology, ileal volatile fatty acids, and antioxidant and stress markers in various biological samples in aged laying hens. A total of 144, 73-week-old Lohman Brown-Lite laying hens were randomly assigned to one of three experimental diets: basal diet (CONT), CONT + 0.2% MSM (MSM), and CONT + 0.3% SS (SS). The trial lasted for 12 weeks. MSM and SS diets contained 0.07% of sulfur, either organic or inorganic. Dietary MSM did not affect egg production or feed conversion ratio at 12 weeks compared with the CONT group. Dietary sulfur did not affect egg quality except for the Haugh unit at 4 weeks, which was lowered (p < 0.05) in the SS group. Compared with the CONT group, a higher (p < 0.05) villus height to crypt depth ratio was observed in the SS group. Dietary sulfur did not affect the percentages of short-chain fatty acids in the ileum. Total antioxidant capacity of the liver increased (p < 0.05) in laying hens fed MSM- and SS-added diets compared with the CONT group. The MSM and SS groups were found to have lowered (p < 0.05) malondialdehyde (MDA) concentration in serum samples compared with CONT. Finally, dietary MSM had the lowest (p < 0.05) MDA concentrations in yolk samples. Taken together, our study showed that dietary organic and inorganic sulfur have positive effects on ileal morphology and antioxidant capacity in laying hens. However, SS-mediated inhibition in laying performance needs to be clarified.

To study on influences of organic selenium on laying performance, Se absorption and utilization, immunity and antioxidant activity, 400（laying rates 85%）hens during the period of 43-week were randomly allocated to 1 of 4 homogeneous treatments： (control treatment，no added Se feed; Na selenite, 0.3 mg Se/kg; yeast selenium, 0.3 mg Se/kg and DL-methionine selenium 0.3 mg Se/kg). Every treatment had 10 replicates, every replicate had 5 hencoops and every hencoop had 2 hens. We hypothesized that organic selenium was better than inorganic selenium, and DL-selenium had advantages over them of yeast selenium in some ways for laying hens. The experiment lasted for 77 d, with the first 7 d for adaptation. Egg production, laying rates and dry matter intake were recorded every day. And Se contents of serum, whole eggs, heart and liver, blood antioxidant and immunity index were analyzed in the 78th d of the study. The results showed Se sources had no significant effects on laying performance and eggs qualities （ P ＞ 0.05 ）, except for the groups of organic selenium increased egg mass or had trends of increasing laying rates compared with the groups of control and inorganic selenium in the tenth week significantly respectively（P﹤0.05 or P=0.07, P=0.06 and P=0.08）. The groups of organic selenium had increased the contents of Se in serum, whole eggs, heart and liver very significantly（P﹤0.01）；and increased glutathione peroxidase activity and antioxidant capacity significantly（P﹤0.05）. At same time, the groups of organic selenium had increased significantly or had trends to increase the immunoglobulin G in serum（P ﹤0.05 or P=0.05）. In a word, adding organic selenium in diets could improve laying performance, strengthen Se absorption and utilizations, antioxidant capacity and immunity of laying hens to the extent in a longer experiment. And the effects of DL-selenium had advantages over them of yeast selenium in some ways. It implicated that DL-selenium was benefited to production of laying hens and selenium-enriched eggs. Key words： Selenium；Laying performance; Absorption and utilization；Antioxidant activity; Immunity Summary text: Selenium is an essential mineral not only for animal nutrition, but also for humans’ nutrition. Organic selenium had more advantages in improvement of laying performance, Se absorption and utilizations, antioxidant capacity and immunity of laying hens. Especially, DL-selenium was a valuable product, which was benefits to improve production of laying hens and develop functional food, selenium-enriched eggs.

Laying Performance

Two hundred and forty laying hens were fed diets supplemented with vitamin C and selenium (Se). Vitamin C was added at 0 or 200 mg/kg, and Se was added as sodium selenite or selenized yeast at 0.3&nbsp;mg/kg. The feed intake and egg production were measured, and egg quality parameters were determined. Supplementation of the basal diet with Se significantly increased the laying performance; however, vitamin C significantly decreased feed intake and egg production. Vitamin C increased vitamin E concentration in the yolk. Both selenite and Se-enriched yeast increased the vitamin E concentration in the yolk and the Se concentration in the yolk and albumen. The oxidative stability of yolk lipids was improved in hens fed diets supplemented with sodium selenite, but not in those fed diets supplemented with Se-yeast. After 28 days of storage, however, the beneficial effect of selenite on lipid stability ceased. The supplementation of the basal diet with vitamin C significantly worsened the oxidative stability of yolk lipids, indicating that vitamin C acted as a pro-oxidant. Thus, vitamin C increased the laying performance and influenced some traits of egg quality. The combined supplementation of vitamin C and Se did not prove to be successful.
