Effects of isoquinoline alkaloids on apparent ileal digestibility of amino acids, acid hydrolyzed ether extract, and starch by young growing pigs fed corn-soybean meal diets

Sangrovit G is a phytogenic feed additive derived from Macleaya cordata composed of isoquinoline alkaloids (IQ), primarily sanguinarine, that are believed to benefit animal performance. Sanguinarine has anti-inflammatory, immuno-modulatory, and antimicrobial effects. As a result, inclusion of IQ in diets for pigs may reduce inflammation in the intestine and thereby increase absorption of essential nutrients.

However, there are no data published for the effects of IQ on digestibility of crude protein, amino acids, starch, and lipids in pigs. Therefore, the objective of the experiment was to test the hypothesis that the apparent ileal digestibility (AID) of crude protein, amino acids, acid hydrolyzed ether extract and starch in corn-soybean meal diets fed to young growing pigs increases as IQ is added to the diet.

Digestibility of energy and nutrients, and concentrations of DE and ME, in Dakota Gold DDGS fed to pigs

In recent years, companies that produce distillers dried grains with solubles (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.

There is limited information about how oil concentration in DDGS influences the digestibility of energy, fiber, and fat when fed to pigs. Therefore, an experiment was conducted to determine the apparent total tract digestibility (ATTD) of energy, neutral detergent fiber (NDF), acid detergent fiber (ADF), and acid hydrolyzed ether extract (AEE), as well as the concentrations of digestible energy (DE) and metabolizable energy (ME) in two sources of DDGS. One source was a conventional DDGS, and the other was Dakota Gold, a low-oil DDGS.

Effect of the form of dietary fat and the concentration of dietary fiber on digestibility of fat by growing pigs

To determine true digestibility of nutrients, endogenous losses from the digestive tract must be measured. Because consistent values for endogenous losses of fat (ELF) in pigs have yet to be determined, the calculation of fat digestibility has mostly been limited to apparent digestibility.

Endogenous losses of fat may be influenced by the form of fat – extracted or intact – and by the concentration of fiber in the diet. The objective of this experiment was to determine the effect of the form of dietary fat on ileal and total tract digestibility of fat in growing pigs. To do so, it was necessary to measure endogenous losses of fat and to correct for the difference in amounts of dietary fiber in diets containing extracted fat and diets containing intact fat.
