Which factors are essential for sow feed intake? And how to help sows to get through the lactation phase better? Answers to these questions were provided in a recent webinar, which is now available for viewing on demand.
Broadcasted on Thursday, March 11, it featured Dr Mark Giesemann, swine technical manager for Adisseo in the United States.
The webinar was divided into 2 pieces. First, Dr Giesemann explained why the sows’ feed intake should be sufficient during lactation. He quoted recent research by Samuel Hawe and others of the Agro-Food Biosciences Institute (AFBI) in Northern Ireland, which clearly indicates that lower feed intake leads to less piglet weaning weight and lower productivity.
That means it is imperative to figure out which factors affect feed intake during lactation. He summed up factors like health, stage of lactation, parity, genetics and gestation feed intake. Also housing parameters make a difference, he said, as well as factors surrounding the feed.
Following up on this introduction, Dr Giesemann shared results of recent trials on how to increase feed intake of lactating sows. He shared information about the feed additive Krave AP. He showed data from for instance studies in Brazil, where it was observed that the feed additive had an impact on increasing sow feed intake. That in turn improves milk yield and litter weight gain, he said.
The feed additive Rovabio received attention as well. This enzyme based feed additive helps with sow feed digestibility, which translates for instance into less weight loss of sows during lactation. He also showed a meta-analysis with supporting evidence.
