Effects of Polyherbal Formulation As a Natural Replacer of Choline Chloride in Weaned Piglet Diets: Impacts on Performance and Blood Parameters

W eaning is arguably one of the most stressful events in the life of the pig (Campbell et al., 2013).During this critical phase, piglets are exposed to a host of stressors, including removal from the sow, transportation, interaction with unacquainted pigs, and the transition from sow milk to a less digestible diet (Pluske et al., 1997).This can result in intestinal and immune system dysfunctions that lead to reduced pig health, feed intake and growth performance (Cabrera et al., 2013;Pié et al., 2004).Likewise, piglets at the time of weaning have reduced digestive enzymatic activity (Hedemann et al., 2006).Pancreatic lipases, pivotal enzymes in the process of lipid digestion and absorption, undergo marked alterations following weaning ( Jensen et al., 1997).Consequently, the capacity for digesting and absorbing dietary lipids in weaned piglets experiences a significant decline (Qiu et al., 2021).
