Abstract
Effective use of certain teaser boar breeds in artificial insemination, a common assisted reproductive procedure, in swine production provides a surmountable outlet to increase farrowing rates, breeding outcomes, and economic gain within the swine industry. Previous studies have emphasized the importance of boar types in swine breeding outcomes; however, this study delves into the divergent characteristics of Meishan and Duroc boars and how their different attributes affect the farrowing rates of Yorkshire-landrace sows at two individual swine operations, a smaller independent facility, and a larger commercial facility. Data was garnered and contrasted for three-year (2015-2017) time spans from each operation. Statistical analysis was conducted utilizing a 95% confidence interval and a two-sample, two-tailed T-test of equal variances. Furthermore, statistical tests were run in Microsoft Excel 2022, version 2402. The smaller independent operation used Duroc teaser boars and had annual farrowing rates of 90, 93, and 97% in 2015, 2016, and 2017, respectively. Similarly, the larger commercial operation used Meishan teaser boars and had annual farrowing rates of 88, 87, and 87%, respectively in 2021, 2022, and 2023. A 95% confidence interval test yielded lower and upper confidence intervals of –4.01 and 15.67. The two-tailed T-test yielded a no difference (p>0.05) between the farms studied. Both statistical tests suggest no differences between the farrowing rates of each operation. To evaluate the true effects of teaser boar breeds on farrowing rates, more replicated studies comparing boar breeds are needed along with larger sample sizes and a broadened geographic scope for the operations included.
