VALUE OF SYSTEMATIC THORACIC ULTRASONOGRAPHY INFORMATION FOR DETECTING BOVINE RESPIRATORY DISEASE (BRD) RELATED LUNG DAMAGE IN CROSSBRED DAIRY CALVESEvan Bryant Long (10715370) 28 April 2021 (has links)
The purpose of this
study is to evaluate the value of systematic thoracic ultrasonography (TUS) for
detecting bovine respiratory disease (BRD) related lung damage in Holstein x
Angus crossbred calves. Because the dairy industry is known to operate on small
profit margins, it is important to assess the potential of this technology to
help prevent the main source of financial loss related to calf production that dairy
producers face. Studies have shown that BRD may impact nearly a fourth of all
dairy calves before weaning. In an industry that is currently growing and
evolving, it is important that producers have all the necessary resources to
operate efficiently. TUS is known to be a quick and accurate predictor of BRD
related lung damage, but this study focuses on the financial implications of BRD
related lung damage on calf growth and efficiency—average daily gain (ADG) and milk-to-gain
(M:G)—and the value of implementing TUS information to make sound management
decisions. TUS along with BRD diagnosis information give producers a unique
perspective on future growth and development of calves and could be part of the
solution to promote larger profit margins for dairy producers. We find that the
value associated with TUS and BRD diagnosis information is between $0.88/head
and $13.44/head and depends on BRD incidence rate, feed price, and feeder price.
Depending on the cost to the farm, it may be beneficial to implement this as a
way to manage BRD damage, which we know to influence calf growth and efficiency.
