Effects of Fermex 200 (fermented soybean meal) on growth performance and amino acid digestibility by weanling pigs

Soybean meal (SBM) is one of the most important protein sources in swine diets. However, SBM has high concentrations of non-digestible oligosaccharides, mainly stachyose, raffinose, and verbascose, which may increase diarrhea incidence and reduce nursery growth performance. Fermex 200 (Purina Animal Nutrition, Shoreview, MN, USA) is a new source of fermented SBM that may serve as an alternative to other protein sources in diets fed to pigs. However, there are at this point no data for effects of Fermex 200 on growth performance and amino acid (AA) digestibility when fed to weanling pigs.

Therefore, 2 experiments were conducted to test the hypothesis that the apparent ileal digestibility (AID) and standardized ileal digestibility (SID) of AA in Fermex 200 are greater than in conventional SBM. The second hypothesis was that Fermex 200 supports growth of weanling pigs as well as other protein sources.

Digestibility of phosphorus in enhanced torula yeast and fish meal fed to weanling pigs

An enhanced torula yeast was recently developed as a natural alternative protein source to fish meal and other animal proteins. This ingredient has a lower carbon footprint than other available yeast proteins because it is derived from forestry by-products. The enhanced torula yeast has an improved amino acid (AA) profile, a greater digestibility of AA than fish meal, and an energy value that is not different from that in fish meal. However, there are no data available about the digestibility values of P in this new ingredient. Therefore, an experiment was conducted to test the hypothesis that the values for apparent total tract digestibility (ATTD) and standardized total tract digestibility (STTD) of P in enhanced torula yeast are not different from those in fish meal.

Effects of copper hydroxychloride and distillers dried grains with solubles on intestinal microbial protein concentration and digestibility of energy, crude protein, and acid hydrolyzed ether extract by growing pigs

The requirement for Cu for normal metabolism by weanling pigs is 5 to 6 mg/kg, but it is common practice to include additional Cu in diets for pigs to enhance growth performance. Several modes of action for the improved growth performance have been proposed, and one proposed mode of action is the ability of Cu to alter microbial activity. The apparent total tract digestibility (ATTD) of acid hydrolyzed ether extract (AEE) is improved if Cu hydroxychloride is supplemented to high fiber diets. Therefore, an experiment was conducted to test the hypothesis that inclusion of 150 mg/kg of Cu from Cu hydroxychloride (IntelliBond CII; Micronutrients USA LLC; Indianapolis, IN) to diets fed to growing pigs improves apparent ileal digestibility (AID) and ATTD of AEE, and the AID of crude protein. The second objective was to test the hypothesis that supplementing diets with Cu hydroxychloride can reduce the concentration of microbial protein in the small intestine or in the large intestine by pigs fed a corn-soybean meal diet or a diet based on corn, soybean meal, and distillers dried grains with solubles (DDGS).
