“…The similar trend observed on the eggshell weight showing a slight improvement with dietary inclusion of COLM could therefore be an indication that calcium absorption and utilization, rather than being compromised in the laying hens, was improved with dietary COLM inclusion. These findings corroborated with earlier studies that the herbs included did not affect the egg quality in laying hens (Aro et al, 2009;Dilawar et al, 2021;Adli, 2021).…”

An experiment was conducted to evaluate the effect of graded levels of Chromolaena odorata leaf meal (COLM) on production performance, egg quality characteristics, and serum biochemical parameters on Brahma laying hens. A total of forty-five local laying hens aged 4 to 5 months were weighed and assigned to three treatment groups in a completely randomized design. COLM was used as a supplement and incorporated into the diets at 0, 1, and 2% in diets T0, T1, and T2 respectively. Data were collected on production performance, egg quality characteristics, and serum biochemistry. Results from the study indicate that body weight gain, average weight, and egg volume were low (p<0.05) with treatment T2 compared to control (T0) and the best was obtained with treatment T1. The Haugh unit and percentage hen day production were not negatively affected by the treatment levels of COLM. There were significant (p<0.05) differences in triglyceride, total cholesterol, and urea. Results obtained from this study revealed that the inclusion of 1% of COLM improved the egg quality as well as the health status of the birds without having any detrimental effect on the birds.

“…Therefore, the nutrients absorption enhancement mainly promoted the egg production elevation without affecting the weight and the quality of eggs. Similar situation have been observed by dietary supplementation Mentha arvensis and Geranium thunbergii , which improve egg production and keep egg quality as normal ( Dilawar et al, 2021 ). Furthermore, based on numerous components belong to phytoestrogen, E. ulmoides is a rich source of estrogen receptor modulators ( Yao et al, 2007 ).…”

Since numerous natural components in Eucommia ulmoides belong to phytoestrogen, its effect on hens production deserve more attention. To investigate the potential of E. ulmoides extract used as a feed additive, laying performance, egg quality, yolk cholesterol, yolk fatty acids, yolk fatty, yolk volatile components, albumen amino acids, plasma biochemical parameters, intestinal histology, and gut microbiota of hens (n = 120) were determined between basal diet ( A ) and dietary supplementation low ( B ), middle ( C ), and high ( D ) level E. ulmoides extract for 11 wk. When compared to A group, 2 percentage points elevation in laying rate was observed of D group. Significant up-regulation of immunoglobulin indexes and down-regulation of lipid related indexes in D group were also found if comparison with A group, suggesting that supplementation E. ulmoides extract at a relative high content benefited in immunity enhancing and blood-fat depressing. Meanwhile, obvious variation in albumen amino acids and yolk volatile compounds were inspected as dietary supplementation E. ulmoides extract, especially in D group, implied that the flavor of egg would change under high-level E. ulmoides extract treatment. Besides, villus height and villus height to crypt depth ratio of duodenum, jejunum, and ileum in D group were also significantly higher than that of in A group, indicating high-level E. ulmoides extract contributed to nutrient adsorption via intestinal histology changing. Moreover, the richness, diversity, and composition of gut microbiota in D group also significantly altered with a comparison of A group. These variation caused gut microbiota in D group major enriched in the KEGG pathway of insulin signing pathway, systemic lupus erythematosus, and bacterial invasion of epithelial cells, which were conducive to egg production elevation via facilitating nutrient adsorption, inflammation relieving, blood lipid amelioration, and insulin resistance alleviation. These results indicated that dietary supplementation E. ulmoides extract at high content could serve as a feed additive in the hens industry.

“…Understanding the baseline and evolution of gut microbiota in laying hens throughout the course of their lives was crucial to obtaining optimal performance and gut health. According to new research, supplementing natural plant extracts enhances laying hen performance and egg quality while also modifying the gut microbiome (Kim et al, 2018;Abad et al, 2020;Dilawar et al, 2021).…”

The purpose of this study was to investigate the effects of dietary Bopu powder supplementation on the serum antioxidant capacity, serum biochemical indices, egg quality, and intestinal microbiota. Six hundred and forty-eight 33-week-old Lohmann Brown commercial laying hens were randomly allocated into six groups and fed a basal diet supplemented with 0, 25, 50, 100, 200, and 400 mg/kg Bopu powder for 8 weeks, denoted BP0, BP25, BP50, BP100, BP200, and BP400, respectively. The results showed that dietary Bopu powder supplementation reduced serum cholesterol concentrations (linear, p < 0.01) while increasing serum globulin and albumin concentrations (linear, p < 0.05). Furthermore, the BP50 and BP100 groups had greater serum catalase and glutathione peroxidase activity (p < 0.05). The egg Haugh Units were considerably higher in BP25 and BP50 (p < 0.05), and eggshell thickness was higher in BP25, BP200, and BP400 (p < 0.05) when compared to BP0. Dietary treatment with Bopu powder at doses ranging from 25–100 mg/kg improved glutathione peroxidase and catalase activities while decreasing malondialdehyde concentrations in the yolk (p < 0.05). The addition of Bopu powder increased the diversity of microbiota and the relative abundance of Bacteroidota in the gut. For instance, dietary Bopu powder supplementation of 25–50 mg/kg significantly raised the relative abundance of Enterococcus, Bacteroides, and Fusobacterium in the foregut. Supplementing the diet with 50–100 mg/kg of Bopu powder improved the relative abundance of Lactobacillus in the hindgut. In conclusion, dietary Bopu powder supplementation enhanced the abundance of beneficial bacteria in the foregut of laying hens and improved egg quality and antioxidant capacity. Furthermore, in the laying hen diet, the optimal dosage of Bopu powder additive was 25–50 mg/kg.
