“…The positive effect of tributyrin on egg weight and feed efficiency could be attributed to enhanced breeders’ intestinal health and improved gastrointestinal functionality. Similarly, Feng et al. (2021) also shown that supplementation of monobutyrin at 250 mg/kg level increased egg weight, but had no effect on egg production rate and feed conversion rate in broiler breeders.…”

“…It is also indicated that butyrate and its derivatives (butyric acid, sodium or calcium butyrate, and butyrate glycerides) were found to exert antioxidant effect in animals’ models in vivo or in vitro ( Lin et al., 2014 ; Wu et al., 2016 ; Memon et al., 2019 ; Guo et al., 2020 ). On the same time, lots of studies have demonstrated that sodium butyrate and butyrate glycerides (such as tributyrin and monobutyrin) could improve intestinal health and have beneficial effects on performance of broilers, laying hens and breeders ( Czerwinski, et al., 2012 ; Jahanianand Golshadi, 2015 ; Kaczmarek et al., 2016 ; Bedford et al., 2017 ; Bedford and Gong, 2018 ; Yang et al., 2018 ; Zhao et al., 2019 ; Lan et al., 2020 ; Feng et al., 2021 ). However, the response of broiler breeders with different reproduction performance to tributyrin on ovarian antioxidant capacity and function in is not clear.…”

The objective of this experiment was to investigate the influence of dietary tributyrin on reproduction performance and ovary function of broiler breeders with different egg laying rate. Two hundred fifty-six AA broiler breeders (48-wk-old) were allocated to 4 treatment in a 2 × 2 factorial arrangement with the main effects of tributyrin supplementation (0 and 1,000 mg/kg tributyrin [ TRI ]) and 2 egg laying rate levels (average [ AR , 81.01 ± 0.79%] and low [ LR , 70.98 ± 0.95%]). The results shown that the LR breeders presented higher egg weight, but lower egg laying rate, qualified egg rate and feed efficiency than the AR breeders ( P (laying) < 0.05). Also, the superoxidase dismutase ( SOD ) activity in magnum was lower while malondialdehyde ( MDA ) was higher in ovary and magnum of LR breeders than that in the AR breeders ( P (laying) < 0.05). Dietary supplementation with tributyrin significantly enhanced egg weight ( P (TRI) < 0.05), increased albumen height as well as Haugh unit ( HU ) in AR breeders ( P (interaction) < 0.05), and also had higher total antioxidant capacity ( T-AOC ) and lower MDA in ovary ( P (TRI) < 0.05). The cell apoptosis rate and proapoptosis related gene expression ( caspase 8, 9 and Bax ) in the ovary of LR breeders was higher, while anti-apoptosis related gene ( Bcl-2 ) expression were lower in LR breeders when compared with the AR breeders ( P (laying) < 0.05). Dietary supplementation with tributyrin decreased the cell apoptosis rate and downregulated caspase 9 expression in LR breeders ( P (Interaction) < 0.05), up-regulated the Bcl-2 expression in both 2 breeders ( P (TRI) < 0.05). These findings suggest that the breeders with lower egg laying rate also characterized by deteriorate ovary function indicated by lower antioxidant capacity and higher cell apoptosis rate. Dietary supplementation with tributyrin increased egg albumen quality, decreased ovarian proapoptosis related gene expression to improve reproductive tract function; and the positive effect on egg albumen quality is more pronounced in average reproductive breeders.

The objective of this study was to explore the effects of adding essential oils (EO) to diets on egg quality, biochemical parameters and intestinal flora of late laying hens. The number of 252 Dawu Golden Phoenix laying hens (55 weeks old) were randomly sorted into two groups: the control group (CG) fed a basal diet and the EO group fed a basal diet with 300 mg/kg of essential oils. The average egg weight, feed-to-egg ratio, and egg production rate were determined every week. The trial started at week 55 and lasted for 8 weeks. During the experiment’s last week, 36 eggs out of each group were chosen at random to test. In our study, dietary supplementation with EO considerably decreased the egg breaking rate (p = 0.01) and increased the shell-breaking strength (p = 0.04). The treatment group’s alanine aminotransferase (ALT) levels were considerably lower than those of the control group (p = 0.03). The EO group had substantially higher total antioxidant capacity (T-AOC) and total superoxide dismutase (T-SOD) (p = 0.04 and p =0.03, respectively). However, there were no differences in alpha diversity indicators between the two groups. It is worth noting that Firmicutes were increased considerably (p < 0.05), while Spirochaetota and Proteobacteria were significantly reduced in the EO group. At genus levels, the EO supplementation increased the relative abundance of Intestinimonas (p < 0.05) and Megamonas (p < 0.01). In conclusion, a dietary supplementation of 300 mg/kg EO can improve the production performance of laying hens and the egg quality. It can also regulate the abundance of cecal flora and serum biochemical indicators.

This experiment aimed to determine the effect of dietary supplementation with glycerol monobutyrate (GMB) on egg-laying performance, biochemical indicators, and gut microflora at the late stage of laying hens. A total of 252 healthy Dawu Golden Phoenix laying hens with no difference in body weight were selected and randomly divided into two groups: (1) control group (CG), corn-soybean meal diet, (2) 500 mg glycerol monobutyrate/kg added to the basal diet. Six replicates were set up for each treatment group, with 21 birds per replicate. The trial started at week 55 and lasted for 8 weeks. Compared to the control group, the supplementation with GMB increased egg weight (P = 0.03), shell thickness (P = 0.03) and decreased egg breaking rate (P = 0.04). There was no significant difference in egg production rate, feed-to-egg ratio, egg shape index, eggshell strength, and Haugh unit between the two groups. In addition, dietary GMB decreased the levels of aspartate aminotransferase (P = 0.03) and total bilirubin (P = 0.02) in serum, and increased total antioxidant capacity (P = 0.03) and total superoxide dismutase (P = 0.02). However, alpha diversity indices (Ace, Chao1, Shannon, Simpson, goods_coverage, and PD_whole tree) were not different between the two groups. Notably, dietary GMB significantly decreased the abundances of Proteobacteria at the phylum level and the abundances of Enterobacter at the genus level (P < 0.01), but there was no significant difference in the composition of other cecal microbiota. In summary, the present study revealed that supplementation with 500 mg/kg glycerol monobutyrate improved egg weight, eggshell quality, and antioxidant capacity in serum, but its effect on cecal microbiota composition was limited.
