“…Dikmen [ 29 ] showed that the addition of amino acid compound Zn and Mn in the diets of laying hens could significantly improve the egg weight and egg yield. Liu et al [ 30 ] observed Se levels (0.3 and 0.5 mg/kg) and sources (Yeast selenium and sodium selenite) had no difference in egg weight and feed conversion, but ADFI was improved by 0.3 mg/kg Se of yeast selenium, and an interaction of Se sources and levels was in ADFI. Our results exhibited that different sources of trace elements (Zn, Fe, Cu, Mn, and Se) had a significant influence on average egg weight of laying hens, and the organic forms of trace elements showed a higher laying performance.…”

This study was conducted to investigate the effects of different patterns and sources of Zn, Fe, Cu, Mn, and Se on performance, mineral deposition (liver, kidney, pancreas, spleen, pectorals muscle, and tibia), and excretion of laying hens, then to find an optimal dietary supplemental pattern of trace elements in laying hens. A total of 864 healthy laying hens with similar laying rate (Roman, 26-week-old) were randomly divided into nine treatments, with six replications of 16 birds per replication, including a control treatment and four patterns with different element sources (inorganic or organic): (1) Control treatment (basic diet without added extra trace minerals, CT); pattern 1, NRC (1994) recommended level (NRC-L): (2) inorganic minerals of NRC-L pattern (IN), (3) organic minerals of NRC-L pattern (ON); pattern 2, NY/T 33-2004 recommended level (NY/T-L): (4) inorganic minerals of NY/T-L pattern (IY), (5) organic minerals of NY/T-L pattern (OY); pattern 3, 50% NRC (1994) recommended level (50% NRC-L): (6) inorganic minerals of 50% NRC-L pattern (IHN), (7) organic minerals of 50% NRC-L pattern (OHN); pattern 4, the ratio of minerals in blood of laying hens was taken as the supplement proportion of trace elements, and Zn was supplemented depended on NRC recommended level (TLB): (8) inorganic minerals of TLB pattern (IB), (9) organic minerals of TLB pattern (OB). Two weeks were allowed for adjustment to the conditions and then measurements were made over eight weeks. Supplementation of trace elements led to increased daily egg weight (p < 0.05). Patterns of minerals in diets affected the content of liver Mn, pancreas Mn, tibia Mn, and the tissues Se (p < 0.05). Sources of minerals had positive effects on daily egg weight (p < 0.05), the concentrations of liver Fe, kidney Cu, tissues Se (except spleen), and fecal Se (p < 0.05). In conclusion, diet supplemented with the organic trace minerals of 50% NRC-L pattern (OHN) in laying hens promoted optimum laying performance, mineral deposition, and reduced mineral excretion.

“…Related studies have shown that dietary special substances may have effect on the physiology of laying hens (Celebi 2019;Demir and Kaya 2020), and thus also may effect the quality and the nutritional components of eggs (Wahab et al 2019;Aydin and Bolukbasi 2020;Liu et al 2020;Mahfuz et al 2020). TP can improve health of the body, so it is widely used in livestock and poultry feed.…”

Effect of dietary tea polyphenol (TP) on the content of epigallocatechin gallate (EGCG), catechin (C) in egg yolk, and impact on egg quality and production was investigated. For this purpose, 315 healthy Gallus domestiaus aged 42 weeks were selected and randomly divided into 7 groups. The experimental group added 0.02, 0.05, 0.09, 0.14, 0.19 and 0.24% TP to the basic diet. The control group (CK) was fed basal diet. After 10, 20 and 30 days, 15 eggs were randomly selected from each group for egg quality testing, and 20 eggs were selected for EGCG and C content test in the yolk. The results showed that in the 0.24% TP group, the content of EGCG in egg yolk was significantly higher than that of CK group and the 0.02, 0.05, 0.09 and 0.14% TP groups (P < 0.05), and reached the highest on the 30th day (19.171μg/g). The content of C in egg yolk was significantly higher than that in CK group and the 0.02, 0.05, 0.09 and 0.14% TP groups (P < 0.05); and reached the highest on 30th day (7.071 μg/g). The egg weight of the 0.14% TP group on the 10th day and of the 0.19% TP group on the 20th day were significantly lower than that of the CK group (P < 0.05); the egg yolk weight of 0.14% TP on the 10th and 20th days were significantly lower than that of the CK group (P < 0.05). On the 30th day, compared with the control group, the egg weight of the 0.14% TP group was significantly reduced (P < 0.05), the egg yolk color of 0.05 and 0.14% TP groups was significantly increased (P < 0.05). During the whole experiment, the egg production of 0.24% TP group was significantly higher than that of control group (P < 0.05). In conclusion, adding high concentrations of TP can increase the content of EGCG and C in the yolk; however, it has a certain impact on egg weight, yolk color and eggshell thickness. Adding high concentrations of TP may increase egg production. © 2021 Friends Science Publishers

“…The e cacy of the organic form of selenium was due to its greater utilization and absorption compared to other selenite sources (Utterback et al 2005;Delezie et al 2014;Han et al 2017). Liu et al (2020c) reported that the addition of 0.5 mg/kg SY increases egg yolk Se compare to 0.3 and 0.5 mg/kg SS and 0.3 mg/kg SY. Furthermore, hens fed nano-Se and Se-yeast had a signi cant Se deposition in their egg, liver, and kidney (Meng et al 2020).…”

“…Many studies have shown that supplementing the diet of laying hens with Se improves their antioxidant capacity (glutathione peroxidase, superoxide dismutase, and catalase) (Han et al 2017;Sun et al 2020). Supplementation with Se improves immune and antioxidant status (Sun et al 2020), increases the content of selenium in eggs (Liu et al 2020b), and prevents clinical problems due to de ciency of Se (Nabi et al 2020). Mineral utilization is primarily determined by their bioaccumulation and retention (Li et al 2018).…”

This study compares the effects of sodium selenite, selenium yeast, and enriched bacterial organic selenium protein on antioxidant enzyme activity, serum biochemical profiles, and egg yolk, serum, and tissue selenium concentration in laying hens. In a 112-d experiment, 144 Lohman Brown Classic hens, 23-wks old were divided into four equal groups, each has six replicates. They were assigned to 4 treatments: 1) a basal diet (Con), 2) Con plus 0.3 mg/kg feed sodium selenite (SS); 3) Con plus 0.3 mg/kg feed Se-yeast (SY): 4) Con plus 0.3 mg/kg feed bacterial enriched organic Se protein (ADS18) from Stenotrophomonas maltophilia bacteria. On d 116, hens were euthanized (slaughtered) to obtain blood (serum), liver organ, and breast tissue to measure antioxidant enzyme activity, biochemical profiles, and selenium concentration. The results show that antioxidant enzyme activity of hens was increased when fed bacterial organic Se (ADS18), resulting in a significant (P < 0.05) increase in serum GSH-Px, SOD, and CAT activity compared to other treatment groups. However, ADS18 and SY supplementation increase (P < 0.05) hepatic TAC, GSH-Px, and CAT activity, unlike the SS and Con group. Similarly, dietary Se treatment reduced total cholesterol and serum triglycerides concentrations significantly (P < 0.05) compared to the Con group. At 16 and 18 weeks, selenium concentration in hen egg yolks supplemented with dietary Se was higher (P < 0.05) than in Con, with similar patterns in breast tissue and serum. Supplementation with bacterial organic Se (ADS18) improved antioxidant enzyme activity, decreased total serum cholesterol and serum lipids, and increased Se deposition in egg yolk, tissue, and serum. Hence, organic Se may be considered a viable source of Se in laying hens.
