“…Hematocrit is a measure of the proportion of total blood volume that is red and white blood cells and is closely linked to dehydration (Pagana and Pagana, 2006 ). Tomczak et al (2018) orally drenched high-risk calves with water to rapidly address dehydration at feedlot arrival and observed potential for the practice to improve growth performance during the feedlot receiving period. Mean corpuscular volume was greater ( P < 0.01) in CON compared to other treatments (CST × CHR; P < 0.01).…”

The study objective was to determine the effects of Bacillus subtilis PB6 and/or chromium propionate supplementation on serum chemistry, complete blood count, and fecal Salmonella spp. count in high-risk beef cattle during a 56-d feedlot receiving period and the subsequent finishing period. Four truckload blocks of crossbred beef bulls (n=300) and steers (n=84; total n=384; average initial BW = 220 ± 16.2 kg) were sourced from regional auction markets and assigned randomly to treatments arranged in a 2 × 2 factorial. Blood samples were collected from two bulls nearest the median BW on arrival in each pen (n=96) and fecal samples were collected from cattle in block 3 (n=96). The generalized complete block design consisted of 12 pen replications per treatment with pen as the experimental unit. Treatments were: 1) negative control (CON); 2) 13 g/animal daily of prepared B. subtilis PB6 product (CST); 3) 450 ppb DM chromium propionate (CHR); and 4) 13 g/animal daily of prepared B. subtilis PB6 product and 450 ppb DM chromium propionate (CST+CHR). Treatments were top dressed in feed bunks daily using 0.45 kg/animal ground corn carrier immediately following feed delivery. Data were analyzed using mixed models with repeated measures. Day affected all serum chemistry variables (P ≤ 0.03) except total CO2 (P = 0.34) and all complete blood count variables during receiving (P ≤ 0.02) except percentage basophils (P ≥ 0.12). During the overall receiving period, serum calcium was decreased (P = 0.02) by CHR. Cattle fed CHR had greater total leukocyte count (P = 0.04) and neutrophil count (P = 0.02) during the overall receiving period. Fecal Salmonella spp. count was markedly reduced in cattle fed CST on day 28 (P = 0.01) and overall (P = 0.07). Overall, these data provide metabolic and hematologic insight into the unique challenges presented by lightweight, high-risk feeder cattle. Notably, CST was found to be effective in mitigating fecal enumeration and presumably replication of Salmonella spp. in the gastrointestinal tract.

“…All animal procedures associated with this study were approved by the West Texas A&M University Institutional Animal Care and Use Committee (#02-05-17). There were 3 truckload blocks of high-risk feeder steers and bulls transported 739 km from a central TX order buyer facility to the West Texas A&M University Research Feedlot between June 2017 and September 2017 to evaluate the impact of oral hydration therapy at feedlot arrival on subsequent performance and health (Tomczak et al, 2019). Before arrival, a subset from each block were randomly selected to be fitted with a rumination collar (Allflex Livestock Intelligence, Madison, WI) and a rumen pH and temperature data logging bolus (Well Cow Limited, Roslin, UK).…”

“…Cattle were housed in 6.1 m × 26.9 m soil surface pens providing at least 0.61 m per animal of linear bunk space. Initial processing, BRD case definition, diet (Table 1), and feed bunk management are described in Tomczak et al (2019). It is important to note all bulls were surgically castrated and administered a nonsteroidal anti-inflammatory drug (meloxicam, 1 mg/kg BW) at arrival and a pentavalent modified-live virus (MLV) vaccine (Titanium 5, Elanco, Greenfield, IN) was not administered until day 28.…”

“…Experimental treatments consisted of oral hydration therapy (H2O) or negative control (CON). Oral hydration therapy was administered using a modified drenching apparatus described by Tomczak et al (2019). The H2O treatment was offered 0.57 L water/45.4 kg of BW during initial processing.…”

“…Provision of an oral drench with water in dehydrated or newly received cattle may promote feed intake and improve performance (Stokes and Goff, 2001;Tomczak et al, 2019); however, the underlying mechanisms behind this response have yet to be elucidated. Therefore, the objective of this study was to quantify rumination time, activity, rumen temperature, and rumen pH in high-risk, newly received beef cattle relative to oral hydration therapy with water and clinical BRD incidence.…”

The study objectives were to determine the effect of oral hydration therapy and bovine respiratory disease (BRD) on rumination behavior, rumen pH, and rumen temperature. A random subset of high-risk, auction-sourced bulls from 3 truckload blocks (initial BW = 188.9 ± 19.1 kg) were fitted with a collar containing a 3-axis accelerometer to quantify rumination time and activity (n = 58) and administered a rumen pH and temperature data logging bolus (n = 33). At arrival, subset calves (n = 2 per pen) were balanced across treatment pens (n = 15 per treatment; n = 10 animals per pen) and randomized to receive 0.57 L water/45.4 kg BW from a modified oral drenching apparatus (H2O) or no water administration (CON). Standard arrival processing procedures were implemented including surgical castration. Modified-live virus respiratory vaccination was delayed until day 28. Technicians assigned a clinical illness score (CIS) daily; calves with CIS ≥ 2 and rectal temperature ≥ 40 °C were considered a BRD case (RCASE) and treated with an antimicrobial. The fixed effect of BRD cases vs. nontreated cohorts (RCON) was determined retrospectively using data from the accelerometer collar (n = 19 and 29) and rumen bolus (n = 12 and 21, for RCASE and RCON, respectively). Daily means and hourly means across days throughout the 56-d observation period were generated. Fixed effects were analyzed using the mixed model procedure with repeated measures. Daily rumen temperature was altered (P = 0.04) such that peak rumen temperature occurred earlier for H2O, whereas CON had increased (P ≤ 0.01) rumen temperature following delayed vaccination on day 28. Calves diagnosed with BRD had a transiently decreased (P = 0.04) active minutes between days 9 and 32, decreased (P < 0.01) active minutes between 0800 and 2000 h, decreased (P < 0.01) rumination time between 2000 and 0400 h, greater (P < 0.01) rumen temperature until delayed vaccination on day 28, and greater (P < 0.01) hourly rumen temperature between 0900 and 0300, and altered (P < 0.01) rumen pH. Earlier peak rumen temperature observed in H2O may indicate physiological modification enabling a more pronounced inflammatory response. Differences in rumination behavior and activity may be useful for early BRD detection.
