Affect of ASCOGEN® supplementing in feed to immune response of gestational sows after PRRS and CSF vaccination and sucking piglets

Abstract

The objective of this study was to evaluate the affect of ASCOGEN® supplementing in feed to the immune response of the gestational sows after PRRS and CSF vaccination and the sucking piglets. The studied results showed that the antibody content against hog cholera in the sows eating supplemented ASCOGEN® was (81.43 ± 9.22), higher than that of the control sows (80.77 ± 9.05) after 28 days of vaccination. In the time of before vaccination, there was a difference (P <0.05) of maternal derived antibody (MDA) in the sucking piglets feeding or un-feeding ASCOGEN® came from the sows feeding ASCOGEN® in comparison with the sucking piglets un-feeding ASCOGEN® came from the control sows; and MDA of the sucking piglets feeding ASCOGEN® from the control sows was significantly higher (P <0.05) than that of the sucking piglets un-feeding ASCOGEN®. After vaccination, the antibody content against PRRS in the sucking piglets feeding ASCOGEN® was higher than that of the sucking piglets unfeeding ASCOGEN® came from the same sows feeding ASCOGEN® (P<0.01) and the sucking piglets un-feeding ASCOGEN® came from the control sows (P<0.01). This difference was also expressed in the piglets feeding ASCOGEN® in comparison with those of un-feeding ASCOGEN® came from the control sows (P <0.05). There was a significant difference on the weight of the new-born piglets came from the sows feeding ASCOGEN® and the control sows (1.54 kg±0.23 versus 1.38 kg±0.26), respectively (P <0,05). Similarly the weight of the weaning piglets came from the experimental and control sow groups was 6.2 kg±0.99 versus 5.98 kg±1.09, respectively (P=0.060). The studied results showed that ASCOGEN® supplementing in feed was effective in improving the immune response of the gestational sows after vaccination and the sucking piglets as well as improving the piglet growth performance.
