Milkvetch root feeds gut bacteria that protect sows around farrowing
A compound extracted from milkvetch (Astragalus membranaceus) acts as a prebiotic in sows, feeding gut bacteria that produce butyrate, which in turn reduces inflammation and metabolic stress around the time of birth. Supplementing sows with the extract improved piglet weaning weights, cut maternal fat loss, and shortened the interval before sows returned to reproductive cycling.
