The objective of this study was to evaluate the effects supplementing a Saccharomyces cerevisiae fermentation product (SCFP) on body temperature indices, metabolism, acute phase protein response, and production variables during heat stress (HS). Twenty multiparous lactating Holstein cows (body weight = 675 ± 12 kg; days in milk 144 5; parity 2.3 0.1) were used an experiment conducted 2 replicates (10 cows/replicate). Cows randomly assigned 1 dietary treatments: control diet (CON; n 10) or...
Dairy farm profitability is linked to milk yield and reproductive efficiency. High prolactin levels during lactation can negatively impact fertility. Timed AI protocols like PG7G are used improve pregnancy rates. This study investigates the effects of extending voluntary waiting period (VWP) from 63 73 days after protocol on parameters, including progesterone levels, rates, losses, in lactating Holstein cows summer winter seasons. A total 2100 dairy were divided into groups assigned based...
Postruminal intestinal barrier dysfunction caused by excessive hindgut fermentation may be a source of peripheral inflammation in dairy cattle. Therefore, the study objectives were to evaluate effects isolated acidosis on metabolism, inflammation, and production lactating cows. Five rumen-cannulated Holstein cows (32.6 ± 7.2 kg/d milk yield, 242 108 d milk; 642 99 kg body weight; 1.8 1.0 parity) enrolled with 2 experimental periods (P). During P1 (4 d), fed ad libitum standard cow diet (26%...
Hindgut acidosis (HGA) may cause or contribute to the inflammatory state of transition dairy cows by compromising intestinal barrier. Previous experiments isolating effects HGA on metrics have generated inconsistent results, which be explained acclimation low- versus high-starch diets. Thus, study objectives were evaluate in acclimated a high-fiber diet. Ten rumen-cannulated Holstein (38 ± 5 kg/d milk yield; 243 62 d milk; 1.6 1.1 parity; 663 57 kg body weight) enrolled with 2 experimental...
Study objectives were to determine the effects of mitoquinol (MitoQ, a mitochondrial-targeted antioxidant) on biomarkers metabolism and inflammation during acute heat stress (HS). Crossbred barrows [n = 32; 59.0 ± 5.6 kg body weight (BW)] blocked by BW randomly assigned 1 4 environmental-therapeutic treatments: 1) thermoneutral (TN) control (n 8; TNCon), 2) TN MitoQ TNMitoQ), 3) HS HSCon), or 4) HSMitoQ). Pigs acclimated for 6 d individual pens before study initiation. The trial consisted...
Study objectives were to determine the effects of zinc (Zn) amino acid complex (Availa Zn, Zinpro Corporation, Eden Prairie, MN) on metabolism, biomarkers leaky gut, and inflammation during following heat stress (HS) nutrient restriction. Crossbred gilts (n = 50; 50 ± 2 kg BW) blocked by initial BW randomly assigned one five treatments: 1) thermoneutral (TN) ad libitum fed a control diet (TNCtl), 2) TN pair-fed (PFCtl), 3) Zn-supplemented (PFZn), 4) HS (HSCtl), 5) (HSZn). The study consisted...
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...
Heat-stress-induced inflammation may be ameliorated by antioxidant supplementation due to the purported effects of increased production reactive oxygen species or oxidative stress on gastrointestinal tract barrier. Thus, study objectives were evaluate whether [AGRADO Plus 2.0 (AP); EW Nutrition] affects metabolism and inflammatory biomarkers in heat-stressed lactating dairy cows. Thirty-two mid-lactation multiparous Holstein cows assigned 1 4 dietary-environmental treatments: (1)...
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...
Abstract Study objectives were to determine the effects of rapamycin (Rapa) on biomarkers metabolism and inflammation during acute heat stress (HS) in growing pigs. Crossbred barrows (n = 32; 63.5 ± 7.2 kg body weight [BW]) blocked by initial BW randomly assigned 1 4 environmental-therapeutic treatments: 1) thermoneutral (TN) control 8; TNCon), 2) TN Rapa TNRapa), 3) HS HSCon), or 4) HSRapa). Following 6 d acclimation individual pens, pigs enrolled two experimental periods (P). During P1 (10...
Abstract Study objectives were to determine the effects of dietary live yeast (Saccharomyces cerevisiae strain CNCM I-4407; ActisafHR+; 0.25g/kg feed; Phileo by Lesaffre, Milwaukee, WI) on growth performance and biomarkers metabolism inflammation in heat-stressed nutrient-restricted pigs. Crossbred barrows (n = 96; 79 ± 1 kg body weight [BW]) blocked initial BW randomly assigned one six dietary-environmental treatments: 1) thermoneutral (TN) fed ad libitum control diet (TNCon), 2) TN a...
Abstract. This study was conducted at the Agricultural Research Station of University Jordan in valley to evaluate effect supplementing rumen-protected methionine early lactating Shami goats on milk production, composition, fatty acid profile, and growth performance their kids. Twenty-four fresh were randomly assigned into three dietary treatment groups (eight each) a completely randomized design. Diets control with no supplements or supplemented either 2.5, 5.0 g/head/d rumenprotected...
