By increasing protein digestibility, the offered Enzyme Preparations minimize the amount of undigested protein that enters the hind GI tract and the amount of protein fermentation that occurs in the large intestine, resulting in improved gut health. Because of the enzyme's ability to extract more protein from the protein already present in the feed ration, including a protease to feed rations with low protein levels does not affect performance. The presence of Enzyme Preparations increases protein digestion, resulting in an elevated energy value for the meal overall. Because of the larger impacts of protease activity, it is possible to employ and include more locally accessible protein sources into the diet.
