Effects Of Dietary Selenium Supplementation On Reproductive Performance Of Sows

ABSTRACT

This study was conducted to investigate the effect of dietary selenium (se) supplementation

on the reproductive performance of sows, preweaning growth performance of their piglets,

haematological and antioxidant status of pigs. Twelve (12) crossbred sows (Landrace × Large

White) aged 1-2 years with an average body weight (BW) of 56.1 ± 5kg were randomly

allotted to four treatment groups of three sows per treatment in a completely randomised

design (CRD). The treatment groups comprised T0 (no Se supplementation), and T1, T2, T3

administered with 0.30 mg/Kg seleniummethionine during second trimester of gestation,

third trimester of gestation and lactation respectively. Selenium supplementation significantly

(P0.05) among treatments during the second trimester of gestation. However, Se
