Abstract
This study aimed to evaluate the effects of Saccharomyces cerevisiae var. boulardii (SB) for sows on their productive performance, colostrum and milk composition, and litter performance, in tropical humid climatic conditions. A total of 105 sows (Topigs Norsvin®) were allotted to a 5 × 3 completely randomized factorial design, with five diets (control diet; SBGL4 and SBGL8: 0.04 and 0.08% SB supplementation from the 90th day of gestation until 24th day of lactation; SBL4 and SBL8: 0.04 and 0.08% SB supplementation during lactation) and three parity order groups (PO: 1st and 2nd; 3rd and 4th; 5th to 7th), considering each sow and their litter as experimental unit. Sows above the 5th PO that fed control diet had a lower daily milk production (DMP), number of weaned piglets (NWP), and daily weight gain of litter (DWGL) than sows from 1st to 4th PO that fed the same diet (P < 0.05). Dietary supply of SBGL4 and SBGL8 to older sows provided a higher DMP, NWP, and DWGL when compared to sows of same PO that fed the control diet (P < 0.05). Dietary supply of SBGL4, SBGL8, SBL4, and SBL8 provided a higher dry matter and protein contents in sows' milk of 1st and 2nd PO when compared to sows from same PO that fed control diet (P < 0.05). Dietary supply of SB enhances milk yield of older sows and their litter performance, as well as the dry matter and protein content of younger sows' milk in tropical humid climatic conditions.
