Weaning is a stressful time in a piglet\u2019s life. They undergo social,\u00a0environmental and nutritional stressors at a time when their immune \u00a0system is not fully developed. Th is can precipitate the \u2018post-weaning\u00a0growth lag\u2019, which is characterized by animals going off feed, reduced\u00a0or negative growth rates and increased susceptibility to pathogens. These stresses can trigger an inflammatory reaction in some piglets.\u00a0Although a certain degree of an inflammatory response is beneficial,\u00a0an over-production of inflammatory cells may become detrimental\u00a0to the animals, leading to reduced muscle synthesis or even muscle\u00a0degradation, characteristic of the post-weaning growth lag. \u00a0Over the years, there has been a high degree of interest in nutritional\u00a0modulation aimed at helping piglets cope during this time period. \u00a0Omega 3 fatty acids have many potential health benefits, including\u00a0anti-inflammatory properties. Previous research however, has shown\u00a0conflicting data in terms of inflammatory responses and animal\u00a0performance when \u03c9-3\u2019s are fed. We hypothesize that different\u00a0concentrations of \u03c9-6 fatty acids in the diet among the different studies\u00a0may explain some of these contradictions. In fact, it has been suggested\u00a0that it may be more beneficial to reduce the dietary \u03c9-6 to \u03c9-3 FA ratio\u00a0when feeding pigs than to simply increase the \u03c9-3 amount, in order to\u00a0see benefits.<\/p>\n
