“…1,40 studies have resulted in decreased retreatment or mortality, respectively. 18,32 Additional studies are needed to determine methods to reduce morbidity to reduce antimicrobial use. The increase in percentage of USDA Choice carcasses in the PRO treatment group was likely attributable due to decreased morbidity.…”

Saccharomyces cerevisiae boulardii CNCM I-1079 (live yeast; ProTernative®, Lallemand Animal Nutrition) was evaluated for effects on health and performance in high-risk feeder heifers. A total of 1,274 beef heifers (average body weight = 547 ± 28.7 lb; 248 ± 13.0 kg) were procured from auction markets in the southern United States. Heifers were randomly assigned to 1 of 2 treatments: 1) Control (CON; no yeast products) or 2) ProTernative® (PRO) fed at 1 gram/hd/day to provide 20 x 109 CFU/hd/day for the first 45 days-on-feed (8 pens/treatment). After 45 days-on-feed, PRO was removed from the diet and both the PRO and CON treatment groups were fed the same basal diets throughout the rest of finishing. Feeding PRO during the first 45 days decreased bovine respiratory disease first treatment 28.4% compared to CON (P=0.01), and improved average daily gain (P=0.05; +4.5%), feed:gain (P=0.02; -5.0%), cost of gain (P=0.04; -4.7%), percentage USDA quality grade Choice (P<0.01; +6.8%), and reduced A+ liver abscesses (P<0.01; -45.9%). Carcass weight and percentage USDA Choice carcasses decreased (P<0.01) concomitant with increased (P<0.01) percentage USDA Select carcasses as the number of times treated for bovine respiratory disease increased. Addition of PRO to the ration during the first 45 days improved health, performance, and carcass outcomes through closeout in high-risk feeder heifers.

“…2,3 also known as bovine respiratory disease (BRD). Research studies which used enrofloxacin as the first treatment for BRD after metaphylaxis in high-risk populations resulted in poorer treatment outcomes compared to the current study; 13,14 however, the low-risk populations represented in this study are a greater proportion of the feedlot industry. 15 Tenotryl was provided a biowaiver by the Food and Drug Administration since the active ingredient was the same concentration and dosage form as the pioneer product, and the antimicrobial contains no inactive ingredients which may significantly affect the bioavailability of the active ingredient.…”

The primary objective of this study was to compare the treatment effectiveness of generic enrofloxacin (Tenotryl™ (enrofloxacin) injectable solution; TEN) to pioneer enrofloxacin (Baytril® 100; BAY) for first treatment of naturally occurring bovine respiratory disease (BRD) on subsequent health outcomes in a commercial feedlot. Five hundred cattle identified with BRD by pen riders with rectal temperature ≥ 104.0°F (40°C) were randomized to TEN or the BAY in a 1:1 ratio within each lot. Cattle treated for BRD were returned to their home pen and monitored for 60 days to observe subsequent health outcomes. Cattle were categorized by type (dairy-beef cross or traditional beef breed). General and generalized linear mixed models were used for statistical analyses. There were no differences in first treatment success (64.29% vs 58.16%; P = 0.19) or case fatality risk (10.97% vs 10.65%; P = 0.91) comparing the TEN group to the BAY group respectively. Traditional beef breed cattle had greater body weight at time of enrollment (890.3 lb vs 749.1 lb; P < 0.01) and greater third treatment success (84.44% vs 41.67%; P < 0.01) compared to the dairy-beef cross cattle. There were no differences in health outcomes in cattle administered Tenotryl compared to Baytril 100 for first treatment of BRD in commercial feedlot cattle. From an efficacy perspective, practitioners should be able to use these products interchangeably based upon the results of the study. Additional research on general animal health outcomes of dairy-beef crosses is needed for the industry.

“…The intravenous administration of 60 mcg/kg/day of gonadorelin diacetate tetrahydrate to pregnant rats and rabbits during organogenesis did not cause embryotoxic or teratogenic effects. Further, CYSTORELIN did not cause irritation at the site of intramuscular administration in dogs with a dose of 72 mcg/kg/day administered for seven (7) days.…”

Systematic review and meta-analysis comparing arrival versus delayed vaccination of high-risk beef cattle with 5-way modified-live viral vaccines against BHV-1, BRSV, Pl3, and BVD types 1 and 2

Bovine respiratory disease (BRD) is a major economic and welfare concern of the beef cattle industry. Various approaches to vaccination against the major viral pathogens have been investigated, including timing. It is thought that beef cattle entering feedlots may not be able to adequately respond to vaccination due to the stresses of shipping and processing. A meta-analysis was performed to compare the effectiveness of on-arrival vaccination to vaccination delayed 7 or more days following arrival, using a modified-live viral (MLV) vaccine against bovine herpesvirus-1 (BHV-1 ), bovine respiratory syncytial virus (BRSV), parainfluenza-3 (PI3), and bovine viral diarrhea types 1 and 2 (BVD 1 and 2), on outcomes of BRO morbidity, retreatment risk, and mortality. Eight studies were identified comparing vaccination timing in feedlot cattle via literature search. Mantel-Haenzsel risk ratios were calculated for each outcome, and Forest plots were constructed. In the studies identified, there was no difference in BRD morbidity risk, retreatment risk, or BRD mortality between calves vaccinated at arrival or delayed. Based on the data from the studies analyzed, it would not appear that there is an advantage or disadvantage in terms or morbidity, retreatment risk, or mortality in delaying vaccination.
