摘要: This article involved a broad search of applied sciences for milestone technologies we deem to be the most significant innovations by North American pork industry, during past 10 12 years. Several shifted trajectory improvement or resolved production limitations. Each is being integrated into practice, with exception gene editing technology, which undergoing federal approval process. Advances in molecular genomics have been control porcine reproductive and respiratory syndrome identify piglet genome contributions from each parent. Post-cervical artificial insemination technology not novel, but this now used extensively accelerate rate genetic progress. A was achieved discovery that dietary essential fatty acids, lactation, were limiting reproduction. Their provision resulted dose-related response pregnancy, pregnancy maintenance litter size, especially maturing sows ultimately seasonal infertility. The benefit segregated early weaning (12 14 days age) realized specific pathogen removal nucleus multiplication. Application premature commercial as mortality morbidity increased. Early impairs intestinal barrier mucosal innate immune development, coincides diminished resilience pathogens viability later life. Two important milestones improve precision nutrition growing pigs. first updated publication National Research Council nutrient requirements pigs, collaboration between scientists America Canada. Precision advanced further when ingredient description, metabolically available amino acids net energy (by source plant), became private sector product. decade also led fortuitous discoveries health-improving components ingredients (xylanase, soybeans). Finally, two converged facilitate timely detection multiple population: oral fluids sampling polymerase chain reaction (PCR) analysis. Most critical diseases are routinely monitored fluid prepared analysis using PCR methods.
