DuPont looks to improve amino acid digestibility for grower and finisher pigs

DuPont launched a product for swine, a combination of enzymes and Bacillus probiotics, at the World Pork Expo in Iowa, US earlier this month. 

We spoke to Aart Mateboer, business unit director, animal nutrition at DuPont on the sidelines of last week’s Nutreco run conference, Agrivision 2017, to hear about the benefits of that product, Syncra SWI, for the trade.

He claimed the combination product improves energy and amino acid digestibility for grower and finisher pigs, boosting growth and reducing feed costs.   

The company reported that 75% of pig trials with the product showed a feed conversion ratio (FCR) improvement of more than 3% - it added that when the product is applied to a corn/soy/DDGS-based diet for grower-finisher pigs, producers could achieve cost savings per short ton of $5.00 to $13.00.

“The enzyme is a protease that helps release proteins and amino acids out of a complex of fiber matrix that is typically in the diet. The probiotic also secretes protease enzymes while it is in the gut. It is the feed composition that triggers the probiotic to make those enzymes, and the composition of those enzymes depends on the feed, so it is a very flexible combination that sort of adjusts itself to get the optimal performance based on the feed composition that the animal is getting,”​ said Mateboer

“Our technical team will also work with the farmer to really fine tune the feed composition to optimize cost and performance,” ​he added.

He said the probiotic in Syncra SWI consists of spore-forming Bacillus strains that are highly stable to heat and processing, allowing unstable enzymes, which would not normally survive pelleting or the stomach, to be delivered safely to pig’s small intestine, where they are needed to break down substrate.

“We have a large library of bacterial strains. We went through our libraries, and we now have this combination of three strains that, in our experience, give the best performance.”

The multistrain probiotic, said the company, adapts its enzyme production profile to the available substrate in the pig’s small intestine, enabling the same additive to degrade substrate in many different feed ingredients, thus powering the protease component. This solution strengthens gut barrier and stimulates short-chain fatty acid production in the hind gut, contributing to enhanced gut health.  

Probiotics for poultry

On the poultry side, Mateboer said DuPont is now rolling out its three-strain Bacillus strain probiotic feed additiv, Enviva Pro, on the EU market. “It has been very successful in North America, and now registration has been secured for the EU-28,”​ he explained.

The company claimed the product, when used in poultry diets, could maintain a balanced gut microbiota from day one.

Spain is the first port of call for the European launch, France and Italy and other markets will then follow, he said.
