Abstract Objectives were to determine the effects of rapamycin on biomarkers of metabolism and inflammation during acute heat stress (HS) in growing pigs. Crossbred barrows (n=32; 63.5±0.8 BW) where blocked by BW and randomly assigned to 1 of 4 therapeutic-environmental treatments: 1) thermoneutral (TN) control (n=8; TNCtl), 2) TN and rapamycin (n=8; TNRapa), 3) HS control (n=8; HSCtl), or 4) HS and rapamycin (n=8; HSRapa). The trial consisted of 2 experimental periods (P). During P1 (10d), pigs were fed ad libitum and housed in TN conditions (21.3±0.01°C). During P2 (24h), HSCtl and HSRapa pigs were exposed to constant HS (35.5±0.1°C); while TNCtl and TNRapa remained in TN conditions. Rapamycin (0.15 mg/kg BW) was orally administered twice daily (0700 and 1800 h) during P1 and P2. HS increased rectal temperature, skin temperature, and respiration rate compared to TN counterparts (1.28°C, 8.68°C, and 87 bpm, respectively; P< 0.01). Feed intake (FI) markedly decreased in HS relative to TN treatments (64%; P< 0.01). Additionally, pigs exposed to HS lost BW (4 kg; P< 0.01), while TN pigs gained BW (0.7 kg; P< 0.01). Overall, circulating white blood cells decreased in HS compared to TN pigs (19%; P=0.01). Circulating neutrophils did not differ across treatments; however, lymphocytes, monocytes, and basophils decreased in HS relative to TN pigs (23, 33, and 38%, respectively; P≤0.07). Despite marked changes in phenotypic parameters, circulating glucose and blood urea nitrogen did not differ among treatments (P >0.10). However, insulin:FI increased in HS relative to TN treatments (P=0.04). Plasma non-esterified fatty acids (NEFA) increased in HS relative to TN treatments; although this difference was driven by increased NEFA in HSCtl compared to TN and HSRapa pigs (P< 0.01). In summary, pigs exposed to HS had altered phenotypic, metabolic, and leukocyte responses; however, rapamycin administration had little to no effect on any of the variables measured.

Abstract Two experiments were conducted to test the hypotheses that pentoses absorbed from the small intestine of pigs reduce energy utilization and that pentoses that reach the hindgut are fermented. In Exp. 1, 24 barrows (9.95 ± 0.51 kg) with a T-cannula in the distal ileum were allotted to a completely randomized design with 3 diets that contained 15% glucose, 15% xylose, or 15% arabinose. Ileal digesta, feces, and urine were collected from all pigs. Data were analyzed via ANOVA using the Proc Mixed Procedure of SAS. No differences among diets were observed for apparent total tract digestibility of GE or for DE, but ME in xylose and arabinose diets was reduced (P < 0.01) compared with the glucose diet (Table 1) indicating that xylose and arabinose that are absorbed from the small intestine are excreted in the urine. In Exp. 2, 21 barrows (18.02 ± 1.1 kg) were allotted to a completely randomized design with 3 treatments and 7 pigs per treatment. A diet based on corn starch, casein, and 15% glucose was fed for 11 d. On d 4 through 11, saline, xylose, or arabinose (3% of the daily feed) was infused into the cecum of pigs via an ileal cannula, and feces and urine were collected. Data were analyzed as in Exp. 1. Infused xylose or arabinose was not detected in feces of the pigs infused with pentoses indicating that pentoses are fully fermented in the hindgut (Table 1). In conclusion, dietary free pentoses are absorbed prior to the end of the small intestine, but partially excreted in the urine, and therefore may reduce energy utilization. If pentoses are liberated in the hindgut, they may contribute to the energy status of the pig by being fermented with a subsequent absorption of short chained fatty acids.
