“…Serum lactate was greater in 18H steers off-truck ( Beenken et al, 2021 ), and non-active minutes were greater in 18H compared with 8H steers, indicating 18H steers may have been experiencing greater muscle fatigue. In a study assessing two transit durations (12 vs. 36 h) and four rest stop durations (0, 4, 8, and 12 h), calves had a similar percent laying time (58.8% to 61.9%), the day after arriving back to their pens regardless of transit duration or the time allowed to rest ( Meléndez et al, 2020 ).…”

“…Eating times were similar between treatments, though 8H steers had greater eating time at 24 h post-arrival back to the feedlot than 18H steers ( Figure 7D ; treatment × time: P < 0.01). Performance and blood parameter results are described by Beenken et al (2021) .…”

“…These experiments were secondary to primary studies by Deters (2020) and Beenken et al (2021) , and experimental designs were established to address the primary objectives of each study. The objectives of the secondary studies addressed here were to determine if steers display behavioral differences after being transported for 18 h or feed and water deprived for 18 h and if differences in behavior are displayed in steers transported 8 or 18 h. The hypotheses were that after being transported for 18 h, steers would prefer to lay down rather than compete for feed and steers that were transported for 18 h would lay down faster than 8 h steers.…”

“…This study investigated two continuous transit durations, 8 hours ( 8H) and 18 hours ( 18H ; 727 vs. 1,770 km, respectively). To prevent diurnal effects from influencing blood parameters relating to the main experiment ( Beenken et al, 2021 ), steers were stagger transported so the 8H and 18H groups both arrived back to the feedlot at approximately 0700 hours. Transportation was completed using a commercial livestock trailer (Silverstar PSDLC-402; Wilson Trailer Company).…”

“…The current study focused on behavior data collected from two previously conducted experiments designed to assess the effects of transit on feedlot performance and muscle and blood metabolites of beef steers ( Deters, 2020 ; Beenken et al, 2021 ). The objectives of this study were to determine if steers display differences in bunk displacements, latency to eat, drink, and lay down upon return to home pen, and rumination and active behaviors after exposure to different aspects of transit stress, including transit duration and feed and water deprivation.…”

The objective of these experiments was to assess the effects of food and water deprivation and transit duration on the behavior of beef feedlot steers. In Experiment 1, 36 Angus-cross steers (353 ± 10 kg) were stratified to six pens and assigned one of three treatments (n = 12 steers/treatment): control (CON; stayed in home pens with ad libitum access to feed and water), deprived (DEPR; stayed in home pens but deprived of feed and water for 18 h), or transported (TRANS; subjected to 18-h transit event and returned to home pens). In Experiment 2, 60 Angus-cross steers (398 ± 5 kg; 6 steers/pen) were transported either 8 (8H) or 18 (18H) h. Four 8H pens (n = 24 steers) and six 18H pens (n = 36 steers) were used for behavioral analysis. In both experiments, the time to eat, drink, and lay down was recorded for each steer upon return to home pens. Total pen displacements from the feed bunk were also assessed for the two hours following feed access in both experiments. Data were analyzed using Proc Mixed of SAS 9.4, with treatment as a fixed effect. Steer was the experimental unit for behavioral activities, while pen was the experimental unit for bunk displacements. Displacements were analyzed as repeated measures with the repeated variable of time. In Experiment 1, time to eat and drink was similar across treatments (P ≥ 0.17). However, TRANS laid down in 16.5 min while DEPR did not lay down until 70.5 min post-arrival to pen (P < 0.01). Deprived steers had greater bunk displacements in the first 70 min post-feed access than CON or TRANS, though displacements among treatments from 100 to 120 min post-feed access were similar (Treatment × Time: P = 0.02). In Experiment 2, both 8H and 18H steers laid down approximately 25 min post-home pen arrival (P = 0.14). There was no effect of transit duration or duration by time on bunk displacements (P ≥ 0.20), though displacements were greater from 0 to 20 min than from 20 to 30 min post-feed access (Time: P = 0.04). Steers that were deprived of feed and water were highly motivated to access those resources, while transported steers prioritized laying down. Producers should consider these priorities when preparing to receive cattle from a long transit event.

This study investigated the effects of injectable vitamin C (VC) at weaning and prior to transit on growth performance and immune function in early-weaned beef steers. On day 0, 91 Angus × Simmental steers (92 ± 4 kg) were weaned (65 ± 11 d of age), given vaccination boosters, blocked by age, and randomly assigned to weaning (WEAN) treatments: intramuscular injections (20 mL per steer) of VC (250-mg sodium ascorbate per mL; 5 g per steer) or saline (SAL). From days 0 to 48, steers were housed at the Dixon Springs Agricultural Center (Simpson, IL) in pens (six pens; N = 14 to 16 steers per pen) equipped with two to three Vytelle bunks to measure individual daily feed disappearance. On day 49, half of the steers in each WEAN treatment were randomly assigned to an additional injection treatment (20 mL per steer) of VC or SAL prior to transport (TRANS). After administering pretransit injections, all steers were loaded onto a commercial livestock trailer with equal representation of treatments across compartments. Steers were transported for 6 h (approximately 480 km) to the Illinois Beef and Sheep Field Laboratory (Urbana, IL). Upon arrival, steers were sorted into pens (six pens; N = 13 to 17 steers per pen) with 2 Vytelle bunks per pen. Steers were weighed on days 0, 1, 14, 48, 49, 64, 78, 106, and 107. Blood was collected (WEAN = 24 steers per treatment; TRANS = 12 steers per treatment) on days 0, 1, 2, 14, 49 (pre- and posttransit), 50, and 51. Data were analyzed using the MIXED procedure of SAS 9.4 with fixed effects of age block, WEAN, TRANS, and WEAN × TRANS. Plasma ascorbate concentrations were greater (WEAN × time P < 0.01) on days 1 and 2 for steers that received VC at weaning. Similarly, for steers that received VC on day 49 pretransit, ascorbate concentrations were greater (TRANS × time P = 0.04) on days 49 posttransit, 50, and 51. Treatments did not affect (P ≥ 0.13) body weight, average daily gain, or gain to feed throughout the trial. Serum Bovine Viral Diarrhea Virus type 1 and 2 antibody titers on days 14 and 51 were not affected (P ≥ 0.32) by treatment. Injectable VC administered to early-weaned beef steers at the time of weaning or pretransit increased plasma ascorbate concentrations but did not improve growth performance or antibody response to vaccination booster.

The study investigated the effects of 48-h water and feed deprivation on blood and performance of grazing Nellore (Bos indicus) heifers. Twenty-four Nellore heifers (initial body weight [BW] = 238 ± 10 kg; age = 16 ± 2 mo), were ranked by initial BW and age and randomly assigned to 1 of 2 treatments: 1) grazing animals with free access to pasture, water, and mineral-mix (CON; n = 12), or 2) the same grazing conditions but deprived of pasture, water, and mineral-mix for 48 hours (DPR; n = 12). The paddocks consisted of Urochloa brizantha cv. Marandu, using a continuous and fixed stocking rate. The experiment lasted 225 days, with the first 14 days considered as the adaptation period (d -14 to -1) and the subsequent 211 days as the evaluation period (d 0 to 211). From day 0 to day 2, treatments were applied by keeping the DPR heifers in pens and reintegrating them into the experimental area after a 48-hour water and feed deprivation. Individual full BW was recorded on days -14, -13, -1, before (day 0) and after (day 2) treatment application, and on days 6, 11, 12, 41, 42, 210, and 211. Blood samples were collected in the morning on days 0, 2, 6, 12, and 211. A treatment effect was detected (P < 0.001) for shrink BW from day 0 to 2, which was greater (P < 0.001) in DPR vs. CON heifers. Subsequently, DPR animals were lighter (P < 0.001) compared with CON heifers by the end of the deprivation period (d 2). From day 4 to 211, DPR was lighter (P < 0.001) compared with CON heifers after treatment application and for the entire experimental period. In the first 10 days after treatment application (days 2 to 12), DPR heifers showed a partial compensatory ADG (P < 0.001) compared with CON heifers, while no significant differences were observed in ADG between the treatments from days 12 to 42 and 42 to 211 (P > 0.420). Overall ADG (days 2 to 211) was greater (P < 0.001) for DPR vs. CON heifers. All serum variables, except AST, were higher (P < 0.001) in DPR than in CON heifers on day 2 after treatment application. Our study demonstrates that grazing Nellore heifers subjected to 48-hour water and feed deprivation experienced significant alterations in their blood metabolites and BW immediately after the stressful event. Although the deprived heifers partially compensated for their body weight loss in the early days post-deprivation, they remained 12 kg lighter than the non-deprived animals throughout the production cycle.
