“…This study used 10 replicate pens (20 pens total) of eight or nine steers per pen assigned to one of two dietary treatments in a randomized complete block (blocked by batch fraction) design ( Blom et al, 2020 ; Gentry et al, 2020 ). The dietary treatments were incorporated into the total mixed ration using a soybean hull pelleted supplement that was manufactured in October of 2019 (2 weeks prior to the initiation of the experiment) at the South Dakota State University Feed Mill in Brookings, SD, and stored under cover at ambient temperature at the research facility in galvanized bins.…”

“…All data were analyzed using a model appropriate for a randomized complete block design experiment blocked by batch fraction fed from the mixer according to Blom et al (2020) and Gentry et al (2020) using the GLIMMIX procedure of SAS 9.4 (SAS Inst. Inc., Cary, NC), considering dietary treatment and block as fixed effects; no random effects were included in the model.…”

The objective of this experiment was to evaluate the influence of an active live yeast direct-fed microbial (DFM) product on receiving and backgrounding period growth performance and efficiency of dietary net energy (NE) utilization in low health risk beef steers. Maine-Anjou × Angus steers (n = 199; body weight [BW] = 252 ± 32.1 kg) were received from two sources at the Ruminant Nutrition Center in Brookings, SD, in November 2019 and used in a 77-d feedlot receiving and backgrounding experiment. Steers were provided access to long-stem hay and ad libitum water upon arrival. Steers were weighed, vaccinated for respiratory pathogens (source 2 only): infectious bovine rhinotracheitis, bovine viral diarrhea types 1 and 2, parainfluenza-3 virus, and bovine respiratory syncytial virus (Bovi-Shield Gold 5, Zoetis, Parsippany, NJ) vaccinated for clostridial species (Ultrabac 7/Somubac, Zoetis) and pour-on moxidectin (Cydectin, Bayer, Shawnee Mission, KS). Steers (n = 176 steers; initial unshrunk BW = 235 ± 27.6 kg) were allotted to pens (n = 20 pens; 10 pens per treatment; eight or nine steers per pen). Diets were based upon corn silage, dry-rolled corn, and dried distillers grains; dietary treatments were 1) no DFM (CON) and 2) DFM (Levucell SC, Advantage Titan, CNCM l-1077), fed at 10 g/steer/d providing 8 × 109 CFU of active live yeast to each steer daily (DFM). Initial BW was the average of day −1 and day 1 BW (n = 176 steers; initial BW = 253 ± 27.6 kg). On day 21, steers received a 200-mg progesterone and 20-mg estradiol benzoate implant. Data were analyzed from day 1 to 47 (receiving period), day 48 to 77, and from day 1 to 77 as a randomized complete block design; pen served as the experimental unit for all analyses. On day 47 of the experiment, DFM had greater BW (P = 0.01) by 0.9% and average daily gain (ADG; P = 0.01) by 4.2% and gain-to-feed ratio (G:F) tended (P = 0.13) to be 2.8% greater. Day 77 BW did not differ (P = 0.60), cumulative (days 1–77): ADG (P = 0.47), dry matter intake (P = 0.66), and G:F (P = 0.56) were similar. Yeast inclusion had no appreciable influence on performance-based dietary NE utilization or the ratio of observed/expected dietary NE (P ≥ 0.59). In low health risk steers, DFM improved performance during the feedlot receiving period. However, no improvements for DFM were detected for cumulative performance from day 1 to 77. The confirmation of yeast counts indicated the CFU to be above the expected level at the start of the trial but was found below expected level at the end of the trial. This may explain differences during the initial 47 d compared to cumulative growth performance results.

“…No morbidity or mortality was noted in the 56-d receiving study. Blom et al (2020) fed oat hay, dampened oat hay (4 parts oat hay:1 part water), or oat silage across 2 yr to Angus and Angus crossbred steers fed soybean hull-based diets during 42-d receiving periods. No differences among treatments were noted for ADG.…”

Our objective was to review the literature related to the health and management of newly received cattle published since a previous review by Duff and Galyean (2007). Bovine respiratory disease (BRD) continues to be a major challenge for the beef industry. Depending on disease severity, animals treated for BRD have decreased performance and lowered carcass value. Diagnosis of BRD is less effective than desired, and progress on developing real-time, chute-side methods to diagnose BRD has been limited. Systems that combine lung auscultation with temperature and BW data show promise. Assessment of blood metabolites and behavior monitoring offer potential for early identification of morbid animals. Vaccination and metaphylaxis continue to be important tools for prevention and control of BRD, but antimicrobial resistance is a concern with antibiotic use. Dietary energy concentration and roughage source/level continue to be important topics. Mineral supplementation has received considerable attention, particularly the use of organic vs. inorganic sources and injectable minerals or drenches given on arrival. Use of probiotics and prebiotics for newly received cattle has shown variable results, but further research is warranted. Health and nutrition of newly received cattle will continue to be an important research area in the years to come.

“…Thus, there is the formation of ruminal digestion. The viability of calves is significantly influenced by the conditions of feeding and housing and age and associated morphological and physiological characteristics (Blom et al, 2020;Ferreira et al, 2020;Aragona et al, 2021;Salami et al, 2021).…”

The article presents the study results on using grain silage in the feeding ration of replacement heifers. Instead of corn silage, the experimental group of heifers was fed with vetch-barley grain silage in the amount of 3.6 kg per head per day. In the experimental groups of young cattle, the increase in live weight (average daily, absolute, relative) was studied, and the economic efficiency of using grain silage in the diets of heifers was also determined. The study results showed that the absolute gain in the groups of experimental calves was 62.1±2.1 kg, which was higher by 14.6% or 7.9±0.4 kg (p<0.05) than the total gain of the control group, where this indicator was 54.2±1.9 kg. The relative gain of the experimental group was 70.8±1.7%. The relative increase in growing stock from the control group was 61.4±1.5%, which turned out to be 15.31% lower than in the control group (p<0.01). The average daily gains in the experimental group were 690.0±32.1 g, which slightly exceeded the indicator of the control group by 14.6% or 87.8±3.1 g. In the experimental group, the profit was higher by 5924.0 rubles than in control, which ensured an economic effect per head in this group in the amount of 1184.8 rubles.
