Abstract This research investigated the impact of dietary beta-glucan-rich molasses yeast powder (MYP) supplementation on the antibody response to swine fever virus (Titer) and hematology of starter–grower pig. Sixteen cross pigs (30 kg body weight) were equally split into four groups; each group with four replicates and fed four dietary treatments that consisted of basal diets (control) and the basal diets added with 2.5, 5.0, and 7.5% MYP. Feed and water were consumed ad libitum for 44 days. Feed intake (FI), MYP intake (MYPI), beta-glucan intake (BGI), and Mannan-oligosaccharide intake (MOSI) were recorded daily. Titer was evaluated after 15 (Titer15) and 30 (Titer30) days after vaccination, while hematology was analyzed at the end of the experiment. The results indicated that it was unchangeable for ADFI (P > 0.05). No impacts were observed on hematological variables and Titer15 in MYP fed pigs (P > 0.05). However, supplementation with 7.5% MYP increased platelet count (PC) and Titer30 (P < 0.01), but decreased hematocrit (Hct) (P < 0.05). Titer 30 and titer 15 were linked to MYPI, BGI, and MOSI (P < 0.05). Based on the study, feeding starter–grower pigs diets supplemented with 7.5% MYP might enhance the antibody response to swine fever virus 30 days after vaccination, and it has a potential role in the application in prevention of swine fever virus disease.

Introduction Classical swine fever virus (CSF) or hog cholera disease is prevalent in many areas of Asia, as well as parts of Africa, Europe, and America. Due to its much wider regional range and higher overall financial effect, CSF is more essential worldwide in triggering pandemics on all continents (Arzt et al. 2010). Although CSF vaccines are accessible, additional prebiotic use in vaccine substitutes has been investigated (Wang et al. 2008b). Additionally, to improve feed efficiency and mortality and to replace antibiotic growth promoters, beta-glucan are generally added to feed

to enhance the immune status of the animal and increase resistance to microbial diseases (Li et al. 2005; Vetvicka et al. 2014). Immunity obtained from sow’s milk is restricted after weaning piglets, which leads to a decrease in their immune response (Bianchi et al. 1999; Salmon et al. 2009). Furthermore, post-weaning vaccination causes poor immune response in pigs. Supplementing yeast beta-glucan can boost animal immunity (Jin et al. 2018
