There were four treatment diets offered： basal diet （T0）, T0 ＋ 5% FTS （T1）, T0 ＋ 7.5% FTS （T2） and T0 ＋ 10% FTS （T3）. Supplementing sows with 5%-10% FTS increased daily feed intake at all stages and 10% FTS supplementation level performed the highest （P 〈 0.05） at all stages of pregnancy. Litter size increased 1-2 piglets/sow, piglets born alive increased 1.3-3 piglets/sow, piglet birth weight increased 10-160 g/piglet and weaned piglets increased 3.3-5.3 piglets/sow, while mortality was reduced of 18%-27% per sow. Inclusion of FTS at level of 10% in the diet of sows had the highest daily live weight gain of piglets during four suckling weeks （P 〈 0.05）. However, there was no significant difference （P 〈 0.05） among treatments on daily live weight gain of piglets at week 1-2. This study revealed that supplementing sows with FTS during estrus to lactation period improved sows＇ and piglets＇ performances, and reduced piglets＇ mortality up to 29% at weaning.展开更多

There were total 16 late starter local pigs fed with four treatment feeds based on block design with four pigs in each treatment. The four treatment feeds offered consisted of： commercial starter feeds Charoen Pokphand 552 （To）, basal feeds ＋ yeast 2% of daily feeds requirement （T0, basal feeds ＋ yeast 4% of daily feeds requirement （T2） and basal feeds ＋ yeast 6% of daily feeds requirement （T3）. Feed intake, daily weight gain, feed conversion efficiency, protein and crude fiber digestibility were evaluated in the study. The findings showed that supplementing S. cerevisiae into low quality local-based diet improved 0.9%-2.7% feeds＇ crude protein, 10%-19% feeds intake, 1%-6% daily weight gain, 3%-4% crude protein digestibility and 4%-5% crude fiber digestibility, but reduced feeds conversion efficiency by 0.3-0.4. The conclusion drawn is that supplementing S. cerevisiae （yeast） up to 6% improved performances of starter local pigs fed low quality feeds and performed the similar result with feeding commercial starter feeds Charoen Pokphand 552. Further research by widening the range and increasing the level of yeast supplementation could be done.展开更多
