Comparative digestibility of energy and nutrients in diets fed to sows and growing pigs

Results of experiments in Europe have indicated that the apparent total tract digestibility (ATTD) of gross energy and nutrients, as well as the concentration of digestible (DE) and metabolizable (ME) energy, is greater in gestating sows fed close to their maintenance requirement than in growing pigs allowed ad libitum access to feed.

However, no data from North America for the comparative digestibility of energy and nutrients in sows and growing pigs have been reported. Therefore, an experiment was conducted to compare the digestibility of energy and nutrients in sows and growing pigs. A second objective was to develop equations to predict digestibility of energy and nutrients in sows from digestibility values obtained in growing pigs.

Amino acid digestibility in processed soybean products, rapeseed expellers, and a fermented mixture of co-products fed to weanling pigs

Soybean meal is the most common source of protein in swine diets in the United States. However, conventional soybean meal contains antinutritional factors such as antigenic proteins, oligosaccharides, lectins, and trypsin inhibitors that limit its use in diets fed to weanling pigs. Methods of processing soybean meal to remove antinutritional factors have been developed. These include enzyme treatment, fermentation, and the removal of soluble carbohydrates.

Like soybean meal, rapeseed products are usually not fed to weanling pigs due to the presence of glucosinolates and relatively high concentrations of fiber in these products. Previous research has shown that fermentation of soybean meal can reduce antinutritional factors and fiber concentrations. It is possible that fermentation can make 00-rapeseed meals and 00-rapeseed expellers suitable for feeding to weanling pigs, but no research has been conducted to confirm this hypothesis. An experiment was conducted to determine the standardized ileal digestibility (SID) by weanling pigs of crude protein and amino acids in four sources of processed soybean products, conventional soybean meal, conventional 00-rapeseed expellers, and in a fermented mixture of co-products including 00-rapeseed expellers, wheat bran, potato peel, and soy molasses.
