The fluctuating prices of traditional feed ingredients for pigs such as barley, wheat and soybean meal have made alternative, cheaper feed sources interesting.
However, a number of these feed materials have a high fibre content, which makes them difficult for pigs to digest. The fibre in the feed can also lower the digestibility of other nutrients, particularly protein.
Scientists from Aarhus University have found a potential solution to the problem.
Fermentation and inclusion of enzymes are both in their own promising methods for improving the nutritional value of the fibre-rich liquid feed. In her PhD study in the Department of Animal Science, Aarhus University, Grethe Venås Jakobsen examined the effects of combining the two methods.
She found that digestibility was improved by combining fermentation with enzyme addition. This was true for several nutrients, but especially for phosphorus and fiber. If you want to know more about dried molasses feed browse http://www.kmuch.com/ .
Enzyme inclusion and fermentation each have their benefits and are complementary processes. Find all about natural animal feed through http://www.kmuch.com/ .
The principal advantage of fermenting the feed material was that it enhances the digestibility of phosphorus. The main benefit of enzyme addition was that the decrease in fibre content in the feed and increased fibre digestibility.
The studies included feedstuffs such as high moisture maize, peas, rapeseed cake and dried distillers grain with solubles.
For several of those materials the biggest challenge is the large amount of Non-starch polysaccharides and lignin that have a low digestibility in pigs and may have a negative impact on the digestibility of protein and other nutritional supplements.
