Last year the Allen D. Leman Swine Conference was held online because that was the only way. This September 18-21, we are holding the industry’s premier health and production management conference as a hybrid event because it is the best way for you.Continue reading “Leman swine conference 2021: science-driven solutions your way”
Efficient and highly effective control of infectious diseases can be achieved by targeting interventions towards farms that are highly connected “super-spreaders” in animal movement networks. However, from an implementation standpoint, it is unclear how much movement data is required to gain an accurate picture of farm connectivity, nor how quickly movement networks change over time. For example, can movement data from last year be used to identify potential super-spreaders this year? How often do such analyses need to be updated? Answering these questions is key to moving from science to practice in terms of successful deployment of network-based targeted control strategies in swine production systems. In this study, Dr Dennis Makau and the VanderWaal lab aim to answer these questions for production systems in the United States.Continue reading “Temporal stability of swine movement networks in the U.S.”
Veterinary student, did you shadow a swine practitioner this summer or were involved in an interesting clinical case investigation? Did you work on your veterinary skills by designing a differential diagnosis list or working on a treatment plan? Did you investigate a problem by analyzing production records? Share your work at the Allen D. Leman Swine Conference to win the Morrison Swine Innovator Prize!Continue reading “The Morrison Swine Innovator Prize for DVM Students continues at the Allen D. Leman Swine Conference!”
Drs. Ventura and Zhitnitskiy, faculty members in the College of Food, Agricultural, and Natural Resources and the College of Veterinary Medicine at the University of Minnesota recently published a new article regarding the influence of point-source enrichment on the behavior of gestating sows housed in groups. The article is available in open-access on the Frontiers in Animal Science website.
- Most common observed behaviors were sows being inactive (73%), followed by sham-chewing (16%). Enrichment use made up only 1% of observations.
- Number of observed interactions with enrichment decreased sharply on the second day.
- Low-parity sows, moderately-lame sows, and sham-chewing sows interacted more with the enrichment.
- No increase in adverse effects (agonistic behaviors, sham-chewing) was observed.
This is our Friday rubric: every week a new Science Page from the Bob Morrison’s Swine Health Monitoring Project. The previous editions of the science page are available on our website.
This week, the Science Page is written by Dr. Galvis et al. from the Machado lab at North Carolina State University. They report their results with modeling PRRSv transmission in situations where vaccines can be used as mitigation tools.Continue reading “Modeling the transmission and vaccination strategy for PRRS virus”
