During his PhD work, Takele Feyera researched on how high fiber in the diet for late gestating sows affect piglet survival early at farrowing until weaning. Moreover, Takele studied how the time between last feeding and the start of farrowing associated with piglet survival at farrowing. The result indicated that the high fiber included in the diet for late gestating sows significantly reduced the proportion of stillborn piglets and total preweaning mortality of the piglets in the litter. Moreover, the result highlighted the importance of the time between last feeding and start of farrowing on survival of the piglets at farrowing. The study showed that sows that started farrowing after 6 h of their last feeding before the start of farrowing had longer farrowing duration with more frequent farrowing assistance and high number of stillborn piglets in the litter. The time between last feeding and the start of farrowing has direct effect of sows’ energy status at the start of farrowing. This new knowledge  will contribute to the understanding on how sows should be fed in future for better production performance.

The PhD degree was completed at the Department of Animal Science (ANIS), Science and Technology, Aarhus University.
