Requirement for digestible calcium by 25 to 50 kg pigs at different dietary concentration of phosphorus by growth performance and bone ash concentration

An excess of calcium in swine diets may increase excretion of phosphorus due to formation of Ca-P complexes. Therefore, when formulating diets for pigs, it is important to consider the ratio of calcium to phosphorus. The proper ratio should ensure that both minerals are maximally utilized in the bodies of the pigs.

Effect of a 3 strain Bacillus-based direct-fed microbial on growth performance and intestinal concentrations of volatile fatty acids in nursery pigs fed low- or high-fiber diets

Increasing the inclusion of dietary fiber in nursery pig diets may stimulate beneficial gut microbiota and reduce post-weaning diarrhea. However, the digestibility of nutrients and energy is decreased in high fiber diets. Nursery pigs fed diets high in fiber have been shown to have reduced ADFI and G:F.

Bacillus-based direct-fed microbials (DFM) secrete a large amount and a wide variety of fiber degrading enzymes. It is thought that feeding DFM may offset some of the negative effects of a high fiber diet. Therefore, an experiment was conducted to test the hypothesis that addition of a Bacillus-based DFM will increase fermentation of dietary fiber and improve growth performance when fed to nursery pigs.

Effect of particle size of calcium carbonate on growth performance in growing pigs

In poultry, the particle size of inorganic calcium sources has been shown to affect calcium retention and eggshell quality. However, little is known about the effect of particle size of inorganic calcium fed to pigs. Results of a previous experiment conducted in the Stein Monogastric Nutrition Lab indicated that calcium digestibility and retention were not affected by the particle size of supplemental calcium carbonate. A follow-up study was conducted to test the hypothesis that calcium carbonate particle does not affect growth performance by weanling pigs.

Growth performance and bone mineralization in weanling pigs fed diets containing different levels of digestible calcium and digestible phosphorus

It is important to include calcium and phosphorus in the diets in the proper proportions because the excess or deficiency of one mineral may affect the utilization of the other. Calcium requirements in the 2012 NRC are based on a model, which used a 2.15 ratio of total calcium to standardized total tract digestible (STTD) phosphorus. An optimal ratio of STTD calcium to STTD phosphorus has not been reported because not enough data exist on the standardized total tract digestibility of calcium. However, recent studies conducted by the Stein Monogastric Nutrition Lab have determined values for STTD calcium for several calcium sources. With these data, it is possible to determine the requirement for STTD calcium. Therefore, an experiment was conducted to determine the requirement of STTD calcium to maximize growth performance and bone ash in 11 to 25 kg pigs.

Effects of antibiotic growth promoters in simple or complex diets fed to weanling pigs

Recently, the Food and Drug Administration announced that the number of antibiotic growth promoters that are available to be used by pigs will be reduced to reduce the risk of transferring antibiotic resistance from animals to humans. Only antibiotics that are not used in human medicine may be used as antibiotic growth promoters by animals in the future. To accommodate this change, it may be necessary to re-evaluate the use of antibiotic growth promoters in diets fed to pigs. It is possible that antibiotic growth promoters may be eliminated from swine diets if the complexity of the diets is increased. To test this hypothesis, an experiment was conducted to determine the effects of using an antibiotic growth promoter in diets formulated to vary in complexity.
