Effect of Rye for Transition Sows on the Level of Piglet Serum Immunoglobulin Immunocrit

A sustainable increase in livestock productivity cannot be achieved without the use of animal feed. Due to growing awareness long-term benefits sustainability, there is an increasing interest replacing traditional feed resources with most feedstuffs pig production. Rye production relatively compared wheat. This farm study investigated whether newborn body weight as well antibody transfer piglets (serum immunoglobulin immunocrit) are affected by feeding rye instead wheat grain transition sows. total 237 sows and their (n = 711) from three farms located northern Germany participated this study. During period, were fed either a wheat-based diet used control (CON) or 30% (RYE) for 7 days before calculated farrowing date. On day farrowing, piglet weights within 24 h post-natal (PN) recorded, blood samples taken lightest, medium, heaviest each litter determine quantification immunoglobulins piglets. Feeding rye-based diets showed no differences newborns (within h) CON group all categories, except on Farm C light medium piglets, where high BW observed group. The immunocrit ratio did not show any between both groups. relationship ratios RYE groups was only A. Overall, that including amounts up sows’ during period had negative effects therefore can considered adequate replacement (up 30%) However, future research needed higher proportion may used.
