Digestibility of amino acids in high-oil corn product fed to growing pigs

Corn is a cereal grain that is commonly used as a feed ingredient for swine diets due to its excellent palatability, and it can easily be grown on a wide range of environmental conditions. Conventional breeding of corn has generated a new variety (i.e., high-oil corn; Byron Seeds LLC, Rockville, IN), which is believed to contain more oil and crude protein (CP) than conventional corn. It is, therefore, possible that this high-oil corn may be comparable to other cereal grains and may serve as alternative to corn for pigs. However, there are at this point no data to demonstrate the nutritional value of high-oil corn. Therefore, an experiment was conducted to test the hypothesis that the standardized ileal digestibility (SID) of amino acids (AA) in high-oil corn is greater than in conventional corn.

Amino acid digestibility in cheese co-product, in fish meal, and in HP 300 fed to weanling pigs

Whey, which is a co-product from dairy processing plants that extract fat and protein from milk to make cheese has been used in diets fed to weanling pigs as a source of lactose. Whey powder does not contain much protein because the majority of the milk protein ends up in the cheese during processing. However, cheese co-products, which contain 40 to 50% crude protein may be used in the feeding of pigs but there is limited information about the nutritional value of cheese co-products fed to pigs. Therefore, it was the objective of this experiment to measure the apparent ileal digestibility (AID) and the standardized ileal digestibility (SID) of amino acids (AA) by weanling pigs in a cheese co-product and compare values to those obtained in fish meal and in a source of enzyme treated soybean meal (HP 300).
