Effects of Calmin on energy, calcium, phosphorus, and nitrogen balance and on growth performance of weanling pigs

Calmin is a calcium supplement produced from sea minerals. It also contains 6% magnesium, which may increase calcium absorption. Calmin has been used as a rumen buffer in dairy cows, but limited data are available for pigs. Therefore, two experiments were conducted to test the effect of feeding diets containing Calmin on calcium, phosphorus, and nitrogen balance, energy balance, and growth performance of weanling pigs.

Effects of different levels of full fat or defatted rice bran on growth performance and carcass quality of pigs

Rice bran is the main coproduct of the production of white rice for human consumption, and is used in livestock diets around the world. Rice bran can be full fat (FFRB), with 14 to 25% fat, or defatted (DFRB), containing 3 to 5% fat.

The type of fat in the diet affects the quality of fat in the pig, because pigs deposit fatty acids in approximately the same proportions as they exist in the diet. A high consumption of unsaturated fat can inhibit the pig's own synthesis of fat, which tends to be more saturated. The amount of unsaturated fatty acids  in fat can be expressed using the iodine value (IV), where high IVs correspond to more unsaturated fat. Increased IV in pig fat can lead to softer bellies, which are less valuable due to reduced shelf life, increased susceptibility to oxidative damage, and reduced belly sliceability.

Effects of Dakota Gold distillers dried grains with solubles (DDGS) and conventional DDGS on growth performance and carcass quality of pigs fed diets as meal or as pellets

Dakota Gold is a low-oil source of distillers dried grains with solubles (DDGS) produced using a cold-fermentation process. Recent research conducted by the Stein Monogastric Nutrition Laboratory has demonstrated that the standardized ileal digestibility (SID) of amino acids is greater in Dakota Gold than in conventional DDGS, but Dakota Gold contains less metabolizable energy (ME) than conventional DDGS.

An experiment was conducted to determine effects on growth performance and carcass characteristics of feeding Dakota Gold or conventional DDGS to pigs from weaning to market. Because limited information exists about effects of pelleting on growth performance of pigs fed diets that contain DDGS, this research also tested the effects of feeding diets containing either Dakota Gold or conventional DDGS in a meal form or in a pelleted form.

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.

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.

Digestibility of NDF and concentration of DE and ME in low-oil DDGS fed to growing pigs

In recent years, ethanol plants have begun extracting more oil from the solubles left over after fermentation. The resulting low oil distillers dried grains with solubles (DDGS) contain less digestible energy (DE) and metabolizable energy (ME) than traditional DDGS.

The fat content of the diet affects the digestibility of energy and nutrients. Because the production of low oil DDGS is a relatively new development, it has not been established that digestibility values are the same across suppliers. Therefore, an experiment was conducted to measure the apparent total tract digestibility (ATTD) of neutral detergent fiber (NDF) and the concentration of DE and ME among DDGS samples from different suppliers.
