“…Khoshbin, Vakili, and Tahmasbi [14] found that feeding late-lay hens a 50/50 or 25/75 ratio of MnSO 4 and AAC Mn increased hen day egg production and egg mass compared to feeding 100% inorganic Mn. Overall, the results of this experiment agree with several previous studies in late-phase laying hens in which feeding AAC or sulfated minerals did not affect egg production [15][16][17][18][19].…”

“…Although some of the diets contained some Zn or Mn from both sources, there were no differences in egg shell quality between treatments. Kim et al [16] found no effect of mineral source on egg shell mineral content. Furthermore, Zhang et al [19] found no change in egg shell mineral content from late-phase laying hens fed any combination of AAC and sulfated trace minerals compared to those fed only sulfated minerals.…”

“…In this experiment, however, egg shell quality as measured by shell weight, specific gravity, Haugh units, breaking strength, and shell thickness did not differ by treatment in any of the three time points. Other researchers found no differences in egg quality in layers fed minerals complexed with amino acid ion or sulfates [16,[21][22][23].…”

Dietary inclusion of copper (Cu), manganese (Mn), and zinc (Zn) can improve egg shell quality through changing the membrane structure. This study aimed to compare the responses of egg shell to different mineral sources. In this study, 60-week-old laying hens (n = 378) were assigned to one of seven treatments with 18 replicates each in an RCBD. Treatments included the following: control (basal + sulfated minerals (CuSO4, MnSO4, and ZnSO4)), and basal + amino acid complexed (AAC) minerals (AAC Cu, AAC Mn, AAC Zn, AAC Cu + Mn, AAC Mn + Zn, AAC Zn + Cu). Trace minerals were added to a basal diet containing 20 ppm MnSO4 and 20 ppm ZnSO4 to achieve overall target concentrations of 20 ppm Cu, 60 ppm Mn, and 60 ppm Zn. The hens were fed the treatment diet for 15 weeks, and egg production and egg quality were assessed during weeks 5, 10, and 15 of the experiment. Egg shells, egg contents, and excreta were analyzed for Cu, Mn, Zn, Ca, and P during weeks 10 and 15. No treatment differences (p > 0.05) were observed for production or egg quality. Differences between excreta mineral content were observed. The mineral content of egg shells and egg contents did not differ (p > 0.05) at any time point. The mineral source did not affect egg mineral deposition and egg quality measures (p > 0.05). Some AAC trace minerals enhanced retention of zinc, calcium, and manganese, although AAC Cu increased Cu excretion. Taken together, feeding AAC trace minerals does not significantly affect egg production or egg quality during the late-lay period. More research is needed to demonstrate whether Cu excretion is increased when feeding AAC Cu due to increased bioavailability or other factors.

Background and Aim: An increase in the productivity of broiler chickens is possible when creating an optimal food base that provides birds with all of the nutrients and biologically active substances required for the fullest realization of their genetic potential. In this regard, we examined the effects of the addition of a water-based probiotic and a chelated form of chromium (Cr) to the diet of birds. Materials and Methods: Sixty 14-day-old male Arbor Acres broilers were used in this study. The birds were assigned to two groups of 30 birds according to their body weights. The control broilers received distilled water with the basal diet, and the experimental group received a probiotic preparation in drinking water and Cr methionine chelate (Cr-Met) in the diet. The feeding period lasted 28 days. Growth performance indices were measured throughout the experiment. At the end of the experiment, blood sampling was performed to assess blood biochemical parameters, antioxidant system indicators, and trace elements. Results: We found that the introduction of a probiotic preparation and a chelated form of Cr into the diet of broiler chickens had a positive effect on meat productivity, which was characterized by a 17% increase in the average daily gain of birds (p = 0.05) and a 14% increase in body weight (p = 0.01). Consequently, the yield of the slaughtered carcass increased by 5.8% (p = 0.05). Against the background of the consumption of the developed diet, broiler chickens exhibited a 14% decrease in feed conversion accompanied by an increase in the level of digestibility of dietary nutrients. In addition, glucose levels were decreased by 20% (p = 0.03) against the background of a 76% increase in the total protein concentration (p = 0.01). Superoxide dismutase and glutathione peroxidase activities were increased by 13% (p = 0.02) and 7.5% (p = 0.03), respectively. Elemental analysis of blood serum revealed a 99% decrease in the Fe level versus the control (p = 0.02) and a 31% increase in the Zn level (p = 0.02). Conclusion: We conclude that feeding broiler chickens is a multicomponent probiotic supplement combined with Cr-Met promotes growth and nutrient absorption, and optimizes metabolic processes. Keywords: antioxidant, broiler chickens, chromium, distilled water.

With the advancement in the egg industry sector, egg quality has assumed great significance in certain countries. Enhancements in the nutritional value of eggs may have direct affirmative consequences for daily nutrient intake and therefore for human health. Thus, affirmative improvement in egg quality boosts consumer preferences for eggs. Also, the improvement in eggshell quality can avoid the disposal of broken eggs and consequently economic losses. Therefore, poultry nutrition and mineral supplements have a significant impact on egg quality. Minerals are crucial in poultry feed for a number of biological processes, including catalytic, physiologic, and structural processes. For instance, they contribute to the biological processes necessary for forming and developing eggshells. To produce high-quality eggs for sale, diets must therefore contain the right amount of minerals. This review aims to highlight the role of both organic and inorganic minerals in improving egg quality, in addition to reviewing the interactions of mineral supplements with intestinal microbiota and subsequent effects on the egg quality.
