Effect of increasing levels of Sylpro yeast on growth performance and blood characteristics of weanling pigs

Sylpro enhanced torula yeast is a high protein feed ingredient derived from forestry by-products, and results from digestibility experiments indicate that Sylpro yeast may be a valuable source of energy and digestible amino acids in diets fed to weanling pigs. As a consequence, it is believed that Sylpro yeast may be included in diets for weanling pigs at the expense of fish meal and other animal protein sources. Therefore, an experiment was conducted to test the hypothesis that increasing levels of Sylpro yeast improve growth performance and blood characteristics of weanling pigs.

Effects of copper hydroxychloride and dietary fiber on intestinal permeability, growth performance, and blood characteristics of nursery pigs

Most diets for weanling pigs contain highly digestible plant and animal proteins, but there is an increasing trend to include more fibrous co-products in diets for pigs due to reduced diet costs. However, feeding diets to nursery pigs with high concentration of dietary fiber may reduce nutrient digestibility, induce intestinal inflammation, and subsequently depress growth performance. Addition of 100 to 200 mg/kg of Cu from Cu hydroxychloride (IntelliBond CII; Micronutrients USA LLC; Indianapolis, IN) to diets improves feed efficiency and reduces post weaning diarrhea in pigs. However, there are at this point no data to demonstrate the effect of Cu hydroxychloride on intestinal barrier integrity of pigs fed low-fiber or high-fiber diets, and it is not known if Cu hydroxychloride influences immune responses of pigs. Therefore, 2 experiments were conducted to test the hypothesis that inclusion of 150 mg/kg of Cu from Cu hydroxychloride reduces intestinal permeability and subsequently improves growth performance of pigs fed diets without or with high concentration of dietary fiber.

Effects of copper hydroxychloride on growth performance and abundance of genes involved in lipid metabolism of growing pigs

Supplementing Cu to diets fed to pigs at 100 to 250 mg/kg may reduce post-weaning scouring and also improve ADG and ADFI. Addition of Cu at 250 mg/kg in diets for pigs containing 5% animal fat improved growth performance, and it was speculated that this is due to the ability of Cu to improve animal fat utilization and enzymatic activity. Inclusion of 45 mg/kg of dietary Cu in diets for rabbits improved body mass gain by upregulating mRNA transcription of fatty acid transport protein, fatty acid binding protein, and carnitine palmitoyl transferase 1, indicating that dietary Cu may influence post-absorptive metabolism of lipids. However, the effect of supplementing dietary Cu on post-absorptive lipid metabolism in pigs remains inconclusive. Therefore, an experiment was conducted to test the hypothesis that addition of 150 mg/kg Cu from Cu hydroxychloride (IntelliBond CII; Micronutrients USA LLC; Indianapolis, IN) to a diet based on corn, soybean meal (SBM), and distillers dried grains with solubles (DDGS) improves growth performance of pigs, and that dietary Cu influences mRNA abundance of genes involved in post-absorptive metabolism of lipids in pigs.

Phosphorus and energy digestibility of Fermex 200 (fermented soybean meal) fed to weanling pigs

Soybean meal (SBM) is one of the most important protein sources in swine diets. However, most P in SBM is bound to phytate, which increases inclusion of inorganic P in diets for pigs. Use of microbial phytase may hydrolyze phytate and subsequently improve P absorption. 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 adding phytase to diets containing Fermex 200 and no data for digestible energy (DE) and metabolizable energy (ME) concentrations of Fermex 200.

Therefore, 2 experiments were conducted to test the hypothesis that inclusion of 1,000 phytase units (FTU)/kg of microbial phytase improves the standardized total tract digestibility (STTD) of P in conventional SBM and Fermex 200. The second hypothesis was that the STTD of P, as well as concentrations of DE and ME in Fermex 200 are greater than in conventional SBM.

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.

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).

Nutritional value of high-lysine sorghum, red sorghum, white sorghum, and yellow dent corn fed to growing pigs

Sorghum is used as an alternative to corn due to its lower cost and wide availability. However, conventional sorghum contains high concentration of tannin and phytate, which act as antinutritional factors. Use of microbial phytase may hydrolyze phytate and subsequently improve P absorption. High-lysine sorghum is a new variety of sorghum which may be comparable to other cereal grains and may serve as alternative to corn for pigs. However, there are at this point no data for effects of adding phytase to diets containing sorghum and no data to demonstrate the nutritional value of high-lysine sorghum.

Therefore, 2 experiments were conducted to test the hypothesis that inclusion of 500 phytase units (FTU)/kg of microbial phytase improves the standardized total tract digestibility (STTD) of P in sorghum varieties. The second hypothesis was that the STTD of P, as well as concentrations of digestible energy (DE) and metabolizable energy (ME) in high-lysine sorghum is not different from that of corn and other sources of sorghum.
