Heat stress (HS) jeopardizes human and animal health reduces agriculture productivity; however, its pathophysiology is not well understood. Study objectives were to evaluate the direct effects of HS on carbohydrate lipid metabolism. Female pigs (57 ± 5 kg body weight) subjected two experimental periods. During period 1, all remained in thermoneutral conditions (TN; 20°C) ad libitum fed. 2, exposed to: (1) constant (32°C) fed (n = 7), or (2) TN pair-fed (PFTN; n 10) minimize confounding...
Proper insulin homeostasis appears critical for adapting to and surviving a heat load. Further, stress (HS) induces phenotypic changes in livestock that suggest an increase action. The current study objective was evaluate the effects of HS on whole-body sensitivity. Female pigs (57 ± 4 kg body weight) were subjected two experimental periods. During period 1, all remained thermoneutral conditions (TN; 21°C) fed ad libitum. 2, exposed to: (i) constant (32°C) libitum (n = 6), or (ii) TN...
Inadequate feed consumption reduces intestinal barrier function in both ruminants and monogastrics. Objectives were to characterize how progressive restriction (FR) affects inflammation, metabolism, morphology, investigate if glucagon-like peptide 2 (GLP2) administration influences the aforementioned responses. Twenty-eight Holstein cows (157 ± 9 d milk) enrolled experimental periods. Period 1 [5 of ad libitum (AL) intake] served as baseline for period (5 d), during which received 6...
Activated immune cells become obligate glucose utilizers, and a large i.v. lipopolysaccharide (LPS) dose causes insulin resistance severe hypoglycemia. Therefore, study objectives were to quantify the amount of needed maintain euglycemia following an endotoxin challenge as proxy leukocyte requirements. Fifteen fasted crossbred gilts (30.3 ± 1.7 kg) bilaterally jugular catheterized assigned 1 2 bolus treatments: control (CON; 10 mL sterile saline; = 7) or LPS + euglycemic clamp (LPS-Eu;...
Heat stress (HS) jeopardizes animal productivity and health. The intestinal barrier is sensitive to HS heat-induced hyperpermeability plays a key role in its pathophysiology. However, the biology of recovery following less understood. Thus, study objectives were determine temporal pattern metabolic, inflammatory, histological parameters during recovery. Female pigs (n = 32; 19.5 ± 0.5 kg BW) sacrificed exposure 1 4 environmental treatments: 1) constant thermoneutral (TN) conditions (TNC;...
Infection and inflammation impede efficient animal productivity. The activated immune system ostensibly requires large amounts of energy nutrients otherwise destined for synthesis agriculturally relevant products. Accurately determining the system's in vivo needs is difficult, but a better understanding may facilitate developing nutritional strategies to maximize study objective was estimate glucose requirements following an i.v. lipopolysaccharide (LPS) challenge. Holstein steers (148 ± 9...
Heat stress (HS) negatively impacts several swine production variables, including carcass fat quality and quantity. Pigs reared in HS have more adipose tissue than energetically predicted, explainable, part, by HS-induced hyperinsulinemia. Study objectives were to evaluate insulin's role altering characteristics during via feeding insulin-sensitizing compounds. Forty crossbred barrows (113 ± 9 kg BW) randomly assigned one of five environment diet treatments: 1) thermoneutral (TN) fed ad...
Study objectives were to determine the effects of chromium (Cr) propionate (Cr 0.04%; 0.5 g/kg feed deliver 200 parts per billion Cr/d; KemTRACE Cr, Kemin Industries, Inc., Des Moines, IA) on growth performance, metabolism, and health biomarkers in heat-stressed nutrient-restricted pigs. Crossbred barrows (n = 96; 105 ± 1 kg BW) enlisted an experiment conducted two replicates, blocked by initial BW, randomly assigned one six dietary-environmental treatments: (i) thermoneutral (TN) fed ad...
Study objectives were to evaluate the effects of replacing 40 mg/kg dietary Zn from sulfate (ZS) with amino acid complex (ZA; Zinpro Corporation, Eden Prairie, MN) on inflammation and intestinal integrity in heat-stressed pair-fed (PF) ruminants. Forty Holstein steers (173.6 ± 4.9 kg) randomly assigned 1 5 dietary-environmental treatments: (1) thermoneutral (TN) ad libitum 75 dry matter (DM) ZS (ZSCON); (2) TN DM (ZSPF); (3) ZA 35 (ZAPF); (4) heat stress (HS) (ZSHS); (5) HS (ZAHS). Before...
High temperatures have detrimental effects on the performance and physiology of broiler chickens. Medicinal plants various biological activities may enhance heat resistance chickens during waves. Therefore, this study aimed to explore potential roles using specific local medicinal alleviate negative impacts stress (HS) in broilers. In study, 180 day-old chicks were used investigate HS dietary indigenous growth performance, antioxidant biomarkers, intestinal health. The assigned six groups...
Summary Butyrate modulates intestinal epithelial cell structure and function. Three hundred sixty Lohmann LSL ‐Classic layer cockerels were used to investigate the effect of butyrate on heat stress‐induced injury integrity. The experiment was conducted from day 85 105 age. birds divided randomly into three treatments: control, stress ( HS ), provided with HSB ) at a level 0.35 g/kg diet. control reared 21 ± 1 °C throughout experiment. treatments exposed cyclic (35 09:00 13:00 09:00)....
Heat stress (HS) has negative impacts on farm animals. Many studies have been conducted in order to ameliorate the effects of heat The current project investigated organic zinc supplementation under thermoneutral and conditions production, physiological, histological parameters broiler chickens. Three-hundred sixty chicks were assigned randomly six different treatments ( n=60 per treatment). (1) a basal diet containing 40 mg kg -1 Zn from an source rearing (TN) (Ctrl); (2) amount +50 % level...
