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.
本研究旨在评估酿酒酵母 var. boulardii（SB）对母猪在热带湿润气候条件下生产性能、初乳和乳汁成分以及仔猪性能的影响。共有 105 头母猪（托佩克种猪）被分配到一个 5×3 完全随机因子设计中，有五种日粮（对照日粮；SBGL4 和 SBGL8：从妊娠第 90 天到哺乳期第 24 天，分别补充 0.04%和 0.08%的 SB；SBL4 和 SBL8：哺乳期分别补充 0.04%和 0.08%的 SB）和三个胎次组别（PO：1 胎和 2 胎；3 胎和 4 胎；5 胎到 7 胎），每个母猪及其仔猪为一个试验单位。第 5 胎次以上、饲喂对照日粮的母猪的日采食量（DMP）、断奶仔猪数（NWP）和仔猪日增重（DWGL）均低于同日粮的 1-4 胎次母猪（P<0.05）。与同胎次的饲喂对照日粮的母猪相比，老龄母猪饲喂 SBGL4 和 SBGL8 日粮可提高 DMP、NWP 和 DWGL（P<0.05）。与同胎次的饲喂对照日粮的母猪相比，饲喂 SBGL4、SBGL8、SBL4 和 SBL8 的母猪的初乳和 1-2 胎次母猪的乳汁中的干物质和蛋白质含量更高（P<0.05）。在热带湿润气候条件下，SB 的添加提高了老龄母猪及其仔猪的生产性能，以及年轻母猪乳汁的干物质和蛋白质含量。
