Effects of GraINzyme and AxtraPhy phytases in restoring performance and bone ash in pigs fed low-phosphorus and calcium diets

Last month's newsletter included a research report on research into a novel E. coli phytase expressed in corn, called GraINzyme. Results of that research indicated that adding GraINzyme phytase to diets fed to young growing pigs increased growth performance, digestibility of calcium and phosphorus, and bone mineralization. The comparative effects of GraINzyme and a commercial phytase was not tested in the previous study. Therefore, an experiment was conducted to compare effects of addition of GraINzyme phytase to the commercial phytase AxtraPhy in diets fed to growing pigs.

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.
