Heat Stress
…from 28d to 49d. Optimal house temperatures were utilized until 43d, when heat stress was applied for 4h ranging from 34C to 36C. After heat stress, birds remained at optimal…
…the thermic effect of digestion, potentially increasing the pig’s susceptibility to heat stress (HS). Heat stress has damaging effects on feed intake and growth performance, costing the swine industry >$900…
…The objective was to measure HP of sows (n = 24) fed control (19.6% CP) or RCP (14.2% CP) under thermoneutral (TN, 21±1.5°C) or cycling heat stress (HS, 32±1.5°C daytime…
The aim of the present study was to investigate the effects of reduced dietary protein levels on metabolism and performance in growing-finishing broilers under thermoneutral temperature or thermal stress. Two…
…the heat stressed pigs, and the SID of arginine and histidine, as well as leucine, was also lower in heat stressed pigs. Neither the AID nor the SID of the…
…intestinal physiological function and promote intestinal health. Oxidative stress is linked to impaired nutrient absorption and growth performance. This study investigated the effects of high-fiber (HF, 6% crude fiber) and…

Inevitably, pigs will experience stressors that antagonize lean tissue accretion, appetite, and feed conversion. Depending on the production system and age of the pig, these stressors commonly include weaning transition,…
L-glutamine (GLN) supplementation improves intestinal integrity and immune function in dairy calves during controlled stress challenges. However, it is unknown whether supplementing milk replacer (MR) with GLN offers similar benefits…
…collected to measure immune and oxidative stress status. Jejunal tissues were used to measure morphology and crypt cells proliferation. In phase 2, xylanase increased (P < 0.05) the average daily…
