A swine nutritionist with the University of Saskatchewan says, when adding fibre to the diets of gestating sows a mixture of soluble and insoluble fibre will offer the best results.
To avoid the problems associated with being too fat pregnant sows are limit fed but this leaves them feeling hungry and can lead to fighting over feed.
Researchers with the University of Saskatchewan, in partnership with Swine Innovation Porc, have been looking at the benefits of providing supplemental fibre to increase satiety among group housed sows.
Dr. Denise Beaulieu, an Assistant Professor Monogastric Nutrition with the University of Saskatchewan, says fibre comes in many forms.
Clip-Dr. Denise Beaulieu-University of Saskatchewan:
Primarily we divide fibre into soluble fibre what we call soluble and insoluble fibre.
Insoluble fibre is what most of us think about when we think about fibre.
That is fibre that, when you eat it you feel full.
That is good for a sow and It gives them a feeling of satiety just due to what we call gut fill.
However that may not last for a long period of time.
If you're just looking at things like straw, straw would be considered an insoluble fibre, even just wheat straw, oat straw, oat hulls, soy hulls or things like that.
Something like beat pulp, a little but more specialized.
Beat pulp would be a very soluble fibre.
Soluble fibre is fibre that will eventually be fermented and broken down in the large intestine of the pigs and these breakdown products, the short chain fatty acids, they actually feed back to the brain and can tell the sow that she's no longer hungry so this then is a longer term type of satiety.
What research has shown, by several groups around the world, that probably a mixture of soluble and insoluble is the best.
Dr. Beaulieu says, among sows provided supplemental fibre during gestation, feed intake was improved during lactation and the growth of their piglets also improved.
