Abstract

This thesis investigated the impact of dairy cow resting area on hygiene, lying behavior, and milk quality. The first cross-sectional study associated different bedding options (sand, straw, wood products, and recycled manure solids (RMS) and barn management practices with low bacterial count, improved cow hygiene, and milk quality. In that study it was demonstrated that elevated bacterial counts could be reported in any of the sampled used bedding types. At the cow level, factors associated with poor body hygiene for cows housed in free-stall barns were greater parity, while the opposite association was reported for cows housed in tie-stall barns. Regardless of housing system, cows in earlier stages of lactation were at higher risk of poor body hygiene when compared to later lactation cows. The second cross-sectional study aided in finding associations among barn management practices, lying behavior, and risk of elevated somatic cell count (eSCC). Lying duration was positively associated with deep-bedded stalls, negatively associated with cow body condition, and negatively associated with dirty stalls. Lameness prevalence was positively associated with dirty stalls. The last longitudinal, controlled study, investigated how the horizontal neck rail position in a free-stall was associated with stall cleanliness, cow hygiene, and the risk for intramamary infection (IMI) and lameness. Neck-rail position on the stall did not influence on SCC, nor in new cases of IMI. A greater percentage of cows had dirty udders when the neck-rail was positioned further from the stall during one of the treatment periods. Also, having a neck-rail positioned further from the curb tended to increase the risk for a new case of lameness in the second week of each treatment period. Finally, stalls were cleaner when bedding was added more frequently. Overall, this thesis provides evidence that bedding management can have a profound impact on cow milk quality, bacterial concentrations in the bedding substrates, and cow behavior, hygiene, and lameness risk. Funding for this research was provided by the Dairy Research Cluster II Initiative, funded by the Dairy Farmers of Canada (Ottawa, ON, Canada), Agriculture and Agri-Food Canada (Ottawa, ON, Canada), the Canadian Dairy Network (Guelph, ON, Canada), and the Canadian Dairy Commission (Ottawa, ON, Canada) through the Canadian Bovine Mastitis and Milk Quality Research Network (St. Hyacinthe, QC, Canada).

Abstract

Euthanasia of mature swine and cattle can be challenging. On-farm euthanasia should be used as a tool to eliminate pain and suffering. However, clear guidelines regarding making euthanasia decisions and alternative euthanasia techniques available for use is limited in the United States (US). In order to prevent prolonged suffering and pain in compromised animals, science-based recommendations are needed to ensure timely and humane euthanasia can be performed when needed on-farm. This presentation will focus on two euthanasia challenges currently faced in swine and dairy cattle systems in the US today: 1) Swine: Validating alternative euthanasia techniques for use in mature breeding stock and 2) Dairy Cattle: Identifying producer barriers preventing timely euthanasia decision-making using surveys and focus groups. The swine study evaluated the effectiveness of two penetrating captive bolt gun styles (cylinder or pistol) using a frontal, temporal and behind-the-ear placement. Four treatments were 100% effective in achieving cardiac arrest and death. The cylinder style captive bolt gun resulted in greater brain trauma and death compared to a pistol style gun and behind-the-ear and temporal placement showed promise as an alternative placement site for euthanizing mature pigs. In the dairy cattle study, dairy producers were recruited to participate in a survey and focus group. Survey results indicated that farm owners were most commonly responsible for on-farm euthanasia and most respondents would treat and monitor compromised cattle for a majority of health conditions, regardless of condition severity. Participants in focus groups focused primarily on animal welfare as the most important factor influencing the decision to euthanize and the desire to eliminate animal suffering by using euthanasia as a tool. This work highlights the complicated challenges that arise when euthanizing livestock and the importance of not only identifying appropriate techniques to humanely euthanize livestock but address the emotional and animal welfare factors that influence these decisions.
