Ileal digestibility of amino acids and starch in hybrid rye compared with other cereal grains fed to pigs

Hybrid rye is grown in Europe, Canada, and the United States, and compared with conventional rye, it has increased yields and reduced risk of ergot contamination, making it an interesting ingredient in the feeding of pigs. However, there is limited information about the nutritional value of hybrid rye when fed to pigs. Therefore, the objective of the experiment was to determine the standardized ileal digestibility (SID) of crude protein and amino acids, as well as the apparent ileal digestibility (AID) of starch in hybrid rye compared with barley, wheat, and corn.

Digestibility of crude protein and amino acids in Dakota Gold distillers dried grains with solubles (DDGS) fed to pigs is greater than in conventional DDGS

Distillers dried grains with solubles (DDGS) is a co-product of ethanol production. In recent years, companies that produce DDGS have begun to remove some of the corn oil for use in biodiesel production. Conventional DDGS contains 10-12% fat, compared with 6-9% in low-oil DDGS.

Research has shown that adding fat to diets fed to pigs increases the digestibility of amino acids in the diets. However, there is limited information about how reduced oil concentration in DDGS influences the digestibility of protein when fed to pigs. An experiment was conducted to compare the standardized ileal digestibility (SID) of crude protein and amino acids in conventional DDGS and in the low-oil DDGS product Dakota Gold, which is produced using a process that does not involve heating.

Ileal digestibility of amino acids in low-oil DDGS fed to growing pigs

Distillers dried grains with solubles (DDGS) are fed to pigs as a source of energy and amino acids. In recent years, ethanol plants have begun recovering corn oil from DDGS to sell for biodiesel and other uses. Conventional corn DDGS contains 10-12 fat, compared with 5-9% fat in low oil DDGS. Previous research in our lab showed that amino acid digestibility was reduced in low oil DDGS compared with conventional DDGS, but that research used DDGS from only one supplier. An experiment was conducted to compare the digestibility of amino acids in low oil DDGS sourced from multiple different suppliers.

Digestibility of energy, and concentration of digestible and metabolizable energy, and ileal amino acid digestibility in conventional and high protein DDGS fed to growing pigs

Distillers dried grains with solubles, or DDGS, is a co-product from the dry-grind ethanol production. It is increasingly in demand for use in livestock feeding, including diets fed to pigs. Conventional DDGS (DDGS-CV) contains approximately 27% crude protein. A high protein DDGS (DDGS-HP) product, containing 38 to 40% crude protein, has recently been developed by Lincolnway Energy by using front end separation that allows for fractionation of the corn kernel before it is fermented. The nutritional value for pigs of the resulting DDGS-HP has, however, not yet been fully described.

Therefore, two experiments were conducted. The objective of the first experiment was to determine the concentrations of digestible energy (DE) and metabolizable energy (ME) and the apparent total tract digestibility (ATTD) of energy in DDGS-HP and DDGS-CV fed to growing pigs. In the second experiment, the standardized ileal digestibility (SID) of crude protein and amino acids in DDGS-CV and DDGS-HP were compared.

Standardized ileal digestibility of amino acids in wheat middlings and red dog fed to pigs

Wheat middlings and red dog are coproducts of the wheat milling process that are used as a source of energy and protein in animal feed. Wheat middlings are granular particles of the wheat endosperm, bran and germ. Red dog consists mainly of the aleurone layer that lies between the bran and the endosperm, along with small particles of bran, germ, and flour. It is often used in extrusion mixtures and as a pellet binder.

The digestibility of crude protein and amino acids in wheat coproducts produced in China has been reported, but there is limited information about the nutritional value of wheat middlings and red dog produced in the United States. In addition, because wheat coproducts vary in terms of the conditions under which they are produced, their nutritional value may vary as well. Therefore, the objective of this experiment was to determine the concentration and digestibility of crude protein and amino acids in ten sources of wheat middlings and in one source of red dog.
