Microbial population in the gastrointestinal tract plays a central role health and nutrient digestion. The objective of present study was to investigate relationships between microbiota apparent digestibility coefficients with respect age diet. Pigs from Large-White, Duroc or Pietrain breeds were raised under same housing conditions fed alternately low-fiber (LF) high-fiber diet (HF) during 4 successive 3-week periods. Data collection for measurements achieved last week each period. At end...
Abstract The present study aimed at investigating the impact of heat challenges on gut microbiota composition in growing pigs and its relationship with pigs’ performance thermoregulation responses. From a total 10 F1 sire families, 558 564 backcross Large White × Créole were raised phenotyped from 11 to 23 wk age temperate (TEMP) tropical (TROP) climates, respectively. In TEMP, all subjected an acute challenge (3 29 °C) 26 age. Feces samples collected both TEMP TROP climate (TEMP23 TROP23...
This study describes the fecal microbiota from piglets reared in different living environments during weaning transition, and presents characteristics of associated with good growth after weaning. Fecal samples were collected pre- (d26) post-weaning (d35) 288 male 16 conventional indoor commercial farms located West France. The changes one week on most abundant microbial families was roughly same all farms: alpha diversity increased, relative abundance Bacteroidaceae (-61%),...
The present study aimed at investigating the evolution of pigs’ fecal microbiota composition from post-weaning to finishing in a longitudinal analysis. experiment was conducted on 160 Pietrain × (Large White Landrace) castrated male and female pigs two replicates. Feces were collected 52, 99, 119, 140, 154 days age for further 16S rRNA sequencing analyze composition. Pig evolved strongly 52 99 with an increased abundance Streptococcaceae decreased Lactobacillaceae. During stage, kept...
Abstract The present study aimed at describing the impact of a deoxynivalenol (DON) - contaminated diet on microbiota composition. A total 147 (Large White x Landrace) Piétrain pigs from two replicates were affected to four different experimental treatments. Pigs in control group (CC) received 99 154 days age. Groups DC, CD, and DD given DON-contaminated (3.02 mg DON/kg feed) for 7 113, 134, 113 134 age, respectively. was formulated with naturally corn. body weight gain feed intake daily...
Abstract This study describes the response of piglet microbiota to weaning in various environments, and investigates whether composition is associated with robustness piglets. Faecal samples growth data were collected just before 7 days after 288 piglets from 16 commercial farms characterised by their pathogenic status antimicrobial use. The effect on most abundant microbial families faecal was roughly same all agreement previous findings. Four enterotypes, ubiquitous farms, identified, for...
Abstract The present study aimed at predicting feed efficiency (FE) based on fecal microbiota, using partial least square regression (PLSR), sparse PLSR, and random forest (RF). Fecal samples from 147 Pietrain x (Large White Landrace) pigs reared in two consecutive batches were collected 99 days of age. Daily live body weight intake individually measured fed ad libitum with a corn soybean diet. relative abundances operational taxonomic units (OTU) resulting 16S rRNA sequencing used to build...
