Dietary Purslane (Portulaca Oleracea L.) Promotes the Growth Performance of Broilers by Modulation of Gut Microbiota

Abstract

Purslane is a widespread wild vegetable with both medicinal and edible properties. It is highly appreciated for its high nutritional value and is also considered as a high-quality feed resource for livestock and poultry. In this study, Sanhuang broilers were used to investigate the effect of feeding purslane diets on the growth performance in broilers and their gut microbiota. A total of 48 birds with good growth and uniform weight were selected and randomly allocated to four treatment groups A (control), B, C and D. Dietary treatments were fed with basal diet without purslane and diets containing 1%, 2% and 3% purslane. The 16S rDNA was amplified by PCR and sequenced using the Illumina HiSeq platform to analyze the composition and diversity of gut microbiota in the four sets of samples. The results showed that dietary inclusion of 2% and 3% purslane could significantly improve the growth performance and reduce the feed conversion ratio. Microbial diversity analysis indicated that the composition of gut microbiota of Sanhuang broilers mainly included Gallibacterium, Bacteroides and Escherichia-Shigella, etc. As the content of purslane was increased, the abundance of Lactobacillus increased significantly, and Escherichia-Shigella decreased. LEfSe analysis revealed that Bacteroides_caecigallinarum, Lachnospiraceae, Lactobacillales and Firmicutes had significant differences compared with the control group. PICRUSt analysis revealed bacteria mainly enriched in carbohydrate metabolism pathway due to the additon of purslane in the diet. These results suggest that the addition of purslane to feed could increase the abundance of Lactobacillus in intestine, modulate the environment of gut microbiota and promote the metabolism of carbohydrates to improve its growth performance. This study indicates that the effect of purslane on the growth-promoting performance of broilers might depend on its modulation on gut microbiota, so as to provide a certain scientific basis for the application of purslane in the feed industry.

Impacts of Purslane (Portulaca oleracea) extract supplementation on growing Japanese quails' growth, carcass traits, blood indices, nutrients digestibility and gut microbiota

“…This reason results in an improvement in intestinal microecology. Also, Wang et al, (2021) found that the gut microbiota of Sanhuang broilers was largely consisted of Gallibacterium, Bacteroides, and Escherichia-Shigella , among other bacteria, according to microbial diversity study. Lactobacillus counts increased considerably as purslane concentration increased, whereas Escherichia-Shigella counts decreased.…”

Is Cost Stickiness a Bad Signal From Catur Marga Perspective?

“…A total of two articles were conceptual papers Guenther et al, 2014), and 24 articles did not discuss the determinants of cost stickiness but instead used them as independent variables. These articles have not been used because they discuss the effects of cost stickiness on, for example, the forecasting of earnings (Ciftci et al, 2016;Ciftci & Salama, 2018;Kaspereit & Lopatta, 2019;Lopatta et al, 2020;Lu et al, 2020;Tang et al, 2020;Weiss, 2010). Be cause our focus is the managers' behaviour, we have dropped 15 articles that discuss, for example, the effect of an auditor's choice, ac counting policies, changes in office address, CEO structure, and changes in the research sample on cost stickiness (Chae & Chung, 2015;Chae & Ryu, 2016;Chung et al, 2019;Ibrahim, 2018;Lee et al, 2019;Loy & Hartli eb, 2018;Shust & Weiss, 2014;Xue & Hong, 2016;Yang, 2015).…”

“…As users of cost account ing information, we need to understand the causes of the asymmetry of cost behaviour, especially cost stickiness. Studies have even shown that cost stickiness (CS) affects the company's stock performance (Ciftci et al, 2016;Ciftci & Salama, 2018;Kaspereit & Lopatta, 2019;Lopatta et al, 2020;Lu et al, 2020;Tang et al, 2020;Weiss, 2010). The asymmetry of cost behaviour is due to individual management considerations in ma king decisions.…”
