Table 2 Microbial effects of resistant starch (RS) in pig studies
From: Resistant starch: Implications of dietary inclusion on gut health and growth in pigs: a review
Test animalsa | Types of RS | Microbial effectsb | References |
|---|---|---|---|
Nursery pigs | RPS (RS 14%) | Increased colonic lactobacilli and Bacteroides | [15] |
Nursery pigs | Purified corn starch (63% amylose) | Increased cecal and colonic Bifidobacterium Decreased Clostridium clusters IV and XIVa | [51] |
Nursery pigs | High amylose corn starch (85% amylose) | Increased proximal colonic Lactobacilli and Bifidobacteria | [47] |
Growing pigs | RS2 in corn, potato, barley, pea, tapioca | Increased fecal lactobacilli and bifidobacteria (meta-analysis) | [99] |
Growing pigs | High amylose corn and RPS (RS 11%) | No significant changes in microbial composition | [42] |
Growing pigs | Retrograded tapioca starch (RS 34%) | Increased colonic Ruminococcus bromii, and bacterial group Clostridium cluster IV, IX, XV, XVI, and XVII Decreased colonic Gammaproteobacteria | [54] |
Growing pigs | Retrograded tapioca starch (RS 33%) | Increased Lachnospiraceae- and Ruminococcus-affiliated phylotypes | [55] |
Cannulated growing pigs | Purified corn starch (63% amylose) | Increased fecal Bifidobacterium | [93] |
Growing-finishing pigs | Purified RPS (RS 13 to 15%) | Increased Coprococcus, Ruminococcus, and Turicibacter Decreased Sarcina and Clostridium | [43] |
Gestating and lactating sows | Pea starch (RS 5 to 9%) | Increased Bifidobacterium and ratio of Firmicutes to Bacteroidetes | [100] |
Pregnant sows | RPS (RS 5%) | Increased fecal Clostridia | [82] |
