Use of O3 Trial Feed to Reduce Omega-6:3 Ratio in PRRS-Virus Challenged Nursery Pigs

A total of 1,056 pigs (PIC TR4 × (Fast LW PIC L02)), originating from an active PRRSV-positive sow farm, were used in a 46-d study to evaluate growth performance nursery fed diets containing increasing levels O3 Trial Feed, source omega-3 fatty acids (alpha-linolenic acid). At placement the nursery, pens randomly assigned 1 4 dietary treatments with 22 per pen and 12 replications treatment. Treatments arranged completely randomized design. Dietary included Feed (0, 0.75, 1.5, 3%) remaining on throughout phases over study. Overall, increased had (linear, P < 0.001) ADG ADFI improved F/G. Pigs also decreased = 0.027) removals mortalities. In summary, reduced mortality pigs.
