The experiment was performed to check the variations in intestine microbiota and metabolic standing of sows with totally different litter sizes on days 30 and 110 of gestation, and to uncover the connection between the composition of maternal intestine microbiota throughout gestation and sow reproductive efficiency. Twenty-six Giant White × Landrace crossbred multiparous sows (2nd parity) with comparable again fats thickness and physique weight had been assigned to 2 teams [high-reproductive performance group and low-reproductive performance group] in accordance with their litter sizes and fed a standard gestation food regimen.
Outcomes confirmed that in contrast with low-reproductive efficiency sows, high-reproductive efficiency sows had considerably decrease plasma ranges of triglyceride on gestation day 30, however had considerably greater plasma ranges of triglyceride, non-esterified fatty acid, tumor necrosis factor-α, and immunoglobulin M on gestation day 110. Constantly, high-reproductive efficiency sows revealed elevated alpha range and butyrate-producing genera, in addition to fecal butyrate focus, on gestation day 30; high-reproductive efficiency sows confirmed considerably totally different microbiota neighborhood construction with low-reproductive efficiency sows and had markedly greater abundance of Firmicutes (genera Christensenellaceae_R-7_group and Terrisporobacter) which had been positively associated with litter dimension on gestation day 110 than low-reproductive efficiency sows. As well as, plasma biochemical parameters, plasma cytokines, and fecal microbiota shifted dramatically from gestation day 30 to day 110.
Subsequently, our findings demonstrated that microbial abundances and neighborhood buildings differed considerably between sows with totally different litter sizes and gestation levels, which was related to adjustments in plasma biochemical parameters, inflammatory elements, and immunoglobulin. Furthermore, these findings revealed that there was a big correlation between litter dimension and intestine microbiota of sows, and supplied a microbial perspective to enhance sow reproductive efficiency in pig manufacturing.
