“…The inclusion of puerarin in the diet of aged laying hens has been shown to enhance egg production and improve laying performance [ 21 ]. Furthermore, a study conducted on rats found that oral administration of puerarin significantly reduced apoptosis, thereby ameliorating the decline in ovarian reserve function [ 20 ].…”

“…Puerarin (99%) was purchased from Yunnan BioBioPha Co., Ltd. (Kunming, Yunnan Province, China). The daily intake amount of puerarin was based on the relevant literature on mice [ 20 ] and laying hens [ 21 ]. Dietary composition ( Table 1 ) during gestation and lactation was in accordance with National Research Council (2012) recommendations [ 22 ] From gestation until 1 week prior to parturition, 2.4 kg of ration was provided per day (08:00 and 16:00).…”

Puerarin is an isoflavone extracted from Pueraria mirifica, a wildlife leguminous plant. It has been reported to possess antioxidant, anti-inflammatory, and anti-bacterial properties. However, the effects of directly adding puerarin to the diets of sows, in terms of reproductive performance and antioxidant properties, have not been reported. For this study, 240 sows with varying parities were selected and randomly divided into six treatment groups using a two × three experimental design. The six treatment groups consisted of two diets (control and puerarin) and three parities (zero, one, and two parities or more). The puerarin group was supplemented with 1 g/kg of puerarin. The experiment commenced with mating and continued until 21 days post-delivery. The sow reproductive performance was not affected by supplementing their diets with puerarin (p > 0.05). Dietary supplementation with puerarin significantly increased the daily body weight (BW) gain of piglets and their mean BW at weaning (p < 0.05). Compared with the control group, sows in the puerarin group had significantly higher glutathione peroxidase activity in serum and also significantly increased immunoglobulin A and G levels in serum, colostrum, and milk, but significantly lower malondialdehyde concentration in serum (p < 0.05). Thus, puerarin improved the immune response and antioxidant capacity of sows and increased the daily BW gain of their offspring.
