Producing high-oleic acid beef and the impact of ground beef consumption on risk factors for cardiovascular disease: A review.

This review summarizes the effects of high-oleic acid oil and high-oleic acid ground beef interventions on risk factors for cardiovascular disease (CVD) in human trials, and also summarizes studies designed to increase the amount of oleic acid (18:1n-9) in beef. In three human trials, high-oleic acid oils and high-oleic acid ground beef increased plasma high-density lipoprotein cholesterol over baseline values or over high-carbohydrate diets. Neither low-oleic acid nor high-oleic acid ground beef increased risk factors for CVD, confirming earlier studies that used high-oleic acid oils.

Evaluation of an inactivated Neospora caninum vaccine in beef feedlot steers.

Objective: To evaluate effects of vaccination of feedlot steers against bovine neosporosis on weight gain, feed intake and efficiency (feed intake per gain), and carcass characteristics.

Design: Longitudinal observational study.

Animals: 60 weaned Brangus steers seronegative for Neospora caninum.
