Abstrakt:	The assessment of animal handling is commonly included in cattle care programs. The guidelines set in the National Cattlemen's Beef Association Beef Checkoff funded Beef Quality Assurance (BQA) program are often used for assessing handling on feedlot, stocker, and cow-calf operations. There is limited information about animal handling on cow-calf operations. Thus, the objectives of this study were to: (1) quantify handling outcomes on cow-calf operations and compare them to national BQA program thresholds, and (2) investigate factors associated with handling outcomes. Researchers visited 76 operations across the United States to observe the following outcomes, adapted from the BQA program, during the processing of cows or yearling heifers: Prod Use, Miscatch, Vocalization, Jump, Slip/Stumble, Fall and Run. One hundred cows or less (depending on herd size) were observed moving through a restraint system at each operation. Other information specific to the animal type, facilities, and management were also gathered to be explored as potential predictors of handling outcomes. Data were summarized using descriptive statistics on an operation basis and analyzed with multi-predictor ANOVA or Kruskal-Wallis tests to assess the relationship between outcomes and possible explanatory factors. Predictors included in the final analyses were: BQA certification (BQA), animal temperament (TEMP), region (REGION), chute style (CHUTE), and visual contact with humans (VISUAL). The 76 operations were sampled in 24 states (Central, n = 17; East, 30; West, 29), with herd sizes ranging from 10 animals to more than 5,000 animals. A total of 4,804 animals were observed. There were a substantial number of operations exceeding BQA thresholds for Prod Use (34.0%, 26), Miscatch (46.0%, 35), and Fall (31.6%, 24); the averages of these outcomes also exceeded the BQA thresholds (< 10%, 0%, and 2%, respectively). There was an association between Prod Use and several explanatory factors, including SIZE ( P = 0.072), TEMP ( P = 0.001), VISUAL ( P = 0.027), and BQA ( P = 0.104). Miscatch, Vocalization, and Fall all had single associated factors (REGION, P = 0.019; REGION, P = 0.002; VISUAL , P = 0.002, respectively). The VISUAL and TEMP factors had an association with the majority of outcomes. The findings suggest an opportunity for improving handling outcomes, which could be achieved through education and training support regarding the importance of animal handling on-farm. Future work should consider additional aspects of facilities and management that could impact cattle handling outcomes. (© The Author(s) 2022.
