This week, the MSHMP team is sharing the yearly PRRS incidence rates in the 39 participating systems.
Continue reading “Yearly incidence rate of PRRS per MSHMP Participating Production System”
- The average incidence rate for all systems during the entire period described was 0.27 PRRS outbreaks per farm per year.
- The incidence rate of PRRS outbreaks within a system varies across years with some participants continuing to have lower incidences.
This week, the swine nutrition team at the University of Minnesota is presenting their latest publication on food waste and its nutritional value.
Continue reading “Energy, amino acid, and phosphorus digestibility and energy prediction of thermally processed food waste sources for swine”
- The digestibility of energy and nutrients of fish waste, supermarket waste, and vegetable waste was investigated.
- Both fish and supermarket waste were excellent sources of digestible energy, metabolizable energy, and digestible amino acids
- These food waste sources could be used to partially replace corn and soybean meal in swine diets to reduce environmental impact
This week, Dr. Guilherme Preis, graduate student at the University of Minnesota with Drs. Corzo and Vannucci is sharing an update on the prevalence of Senecavirus A in the United States.
Continue reading “Senecavirus A continues to be present in the United States swine herd”
- Senecavirus A continues to present in the US at low levels.
- Sow herds are more likely to test positive than growing pig herds.
- SVA positive herds tend to have a large number of positive samples.
This week, we are presenting a summary of an article published by faculty in the College of Food, Agricultural, and Natural resources Sciences regarding the impact of early-life indicators such as birth-weights on the life of a market pig.
Continue reading “Implications of early-life indicators for survival rate, subsequent growth performance, and carcass characteristics of commercial pigs”
- As litter size increases with the industry’s drive to increase pig production, the number of pigs with low birthweights increase too
- Preweaning growth rate is a critical indicator of a low birthweight pig’s likelihood to reach desired market weight on time
- High birthweight is associated with faster growth at all life stages, earlier marketing, and better carcass quality
This week, the MSHMP team is sharing results from a study looking at how related PRRSv ORF5 sequences from a same area are.
Continue reading “Understanding whether PRRS viruses in a neighborhood are closely related”
- 28 space-time clustering of PRRSv based on producers’ routine molecular surveillance were identified in the course of 2010-2019.
- Being inside or outside a space-time cluster significantly explains the genetic variability of most, but not all cases.
- Assessing space, time, and genetic relatedness relationships in PRRSV transmission is complex, and overall trends might miss important case information.
