“…In our study, these data implied that added Pal-Pro to the diet increased laying rate and decreased FCR. The results were corroborated by Chalvatzi et al (2016) and Zhang et al (2019), who reported that dietary supplements with 0.5% of modified Pal or 7.5 Â 10 8 CFU/kg Pro could improve production performance, decrease FCR and change the caecal microbiota composition of laying hens. Previous investigations have demonstrated that Pal or Pro not only gradually reduced the absorption of low-level mycotoxins and growth of pathogen in the intestine tract, but also increased the activities of digestive enzymes in the intestinal tract (Hosoi et al 2000;Xia et al 2004;Shannon et al 2017;Li et al 2018), thus increase the efficiency of absorbing nutrients and ultimately improve the laying performance of broiler breeders.…”

This experiment was conducted to investigate the effects of different supplementation levels of palygorskite and probiotics complex (Pal-Pro) on laying performance, hatching performance, egg quality, plasma antioxidative status, and immune response of broiler breeders. A total of 432 Xuefeng black-bone chickens (42-week-old) were randomly assigned into four treatments with six replicates of 18 hens. The broiler breeders were fed the basal diet supplemented with 0, 250, 500, and 750 mg/kg Pal-Pro for 8 weeks. The Pal-Pro supplementation linearly or quadratically increased (p < .05) laying rate, fertilisation rate, hatchability of fertile eggs, heath hatched chicks rate, eggshell thickness, yolk index, total antioxidant capacity, activities of total superoxide dismutase, catalase, glutathione peroxidase, and contents of immunoglobulins, interleukin-2, and tumour necrosis factor-a in plasma. With Pal-Pro supplementation increased, feed convention ratio during 5-8 and 1-8 week, embryo mortality, malondialdehyde linearly decreased (p < .05). This finding suggested that dietary supplementation with 750 mg/kg Pal-Pro administration could improve the antioxidative status and immunoglobulins contents in plasma of broiler breeders, which may contribute to an increase in broiler's laying rate, hatching performance, egg quality, such as eggshell thickness and yolk index. HIGHLIGHTS Dietary supplementation of Pal-Pro decreased the feed conversion ratio and embryo mortality of broiler breeders. Dietary supplementation of Pal-Pro improved the laying rate, fertility, hatchability of fertile eggs, and yolk index of broiler breeders. Dietary supplementation of Pal-Pro enhanced the antioxidant capacity and the level of immunoglobulins in the plasma.

“…The biomarkers selected in the control group were Eubacterium_ coprostanoligenes, Clostridiales and Megamonas , while the biomarkers screened in the treatment groups included Phascolarctobacterium , Acidaminococcaceae and Ruminococcaceae_UCG_002 . It was reported that the abundance of Eubacterium_coprostanoligenes of high‐yielding cows, meat ducks and laying hens was significantly higher than that of low‐yielding cows, meat ducks and laying hens (Dai et al., 2018; O’Donnell et al, 2013; Tong et al, 2018; Zhang(a) et al 2019). Clostridiales (50.7%) were the dominant bacteria among cecal microbiota in 21‐day‐old meat ducks at the order level (Dai et al., 2018).…”

The purpose of this study was to examine the effect of gaseous hydrogen sulphide on growth performance and cecal microbial diversity in weaning pigs. A total of 24 weaning pigs (Landrace × Yorkshire × Duroc; average body weight = 8.55 ± 0.68 kg；weaning at 28 days) were selected and randomly divided into four groups (six replicates in each group). The piglets were exposed to hydrogen sulphide (0, 5, 10 and 15 mg/m3) during the experiment period, which lasted 28 days in four controlled environmental chambers. The results showed that exposure to hydrogen sulphide reduced the average daily gain (ADG), average daily feed intake (ADFI), and increased the diarrhoea rate of piglets. Hydrogen sulphide could increase the abundance and diversity of intestinal microbiota. The abundance of Firmicutes and Proteobacteria increased and Bacteroides decreased in the treatment groups. Five biomarkers, such as Eubacterium_1coprostanoligenes, Clostridiales, Phascolarctobacterium, Acidaminococcaceae and Ruminococcaceae_UCG_002 were selected by Lefse analysis. Our results reveal that hydrogen sulphide damaged the growth performance and destroyed the microbial bacteria balance of weaning pigs. The concentrations of hydrogen sulphide should fall below 5 mg/m3.

“…Due to the reproductive hypofunction such as ovarian failure and lower oestrogen levels, the egg production and egg quality decrease rapidly in the late egg‐laying period compared with the peak period (Li et al., 2017; Zhang et al., 2019). The oxidative stress is deemed to be one of the dominating mechanisms of ovarian failure (Devine et al., 2012; Luderer, 2014).…”

Alpha‐lipoic acid improves the reproduction performance of breeder hens during the late egg‐laying period

Breeder hens in the late egg-laying period have lower reproductive performance, manifesting as degraded egg-laying rate, quality and hatching performance. The production performance of laying hens is influenced by breeder hens (Gong et al., 2019; Lang et al., 2019). The Qiling hen, used in the present study, is a Chinese native chicken. It is worth mentioning that, the reproductive performance of these local hens decreases rapidly in the late egg-laying period. Therefore, it is of great significance to find a solution to this problem from the perspective of nutritional regulation. In poultry, many factors are in connection with fertility.
