Up to 30% corn germ may be included in diets fed to growing-finishing pigs without affecting pig growth performance, carcass composition or pork fat quality

Corn germ is a co-product of the wet milling industry that is available for use in swine diets to partially replace the more expensive corn grain. Results of arecent experiment indicated that including 15% corn germ in diets containing 30% DDGS had no negative effects on pig growth performance, carcass composition, or pork fat quality. However, it is not known if greater quantities of corn germ may be included in diets fed to growing-finishing pigs. Therefore, we conducted an experiment to determine if greater levels of corn germ may be included in diets fed to growing-finishing pigs without negatively affecting growth performance, carcass characteristics, muscle and fat quality, or belly quality. The experiment also determined if the presence of DDGS in the diets influences the responses to the inclusion of corn germ.

Negative effects of distillers dried grains with solubles (DDGS) on fat quality of pigs are not ameliorated by addition of corn germ, tallow, palm kernel oil, or glycerol to finishing diets

Distillers dried grains with solubles (DDGS) can be fed in swine diets at an inclusion rate of up to 30% without negatively affecting pig growth performance. However, DDGS contains high levels of polyunsaturated fatty acids (PUFA), which may promote deposition of unsaturated dietary fatty acids in adipose tissue. Consequently, inclusion of DDGS at more than 20% has been shown to result in increased fat iodine values (IV) and soft belly production.  The disadvantages of this decrease in fat quality include reduced shelf life, increased susceptibility to oxidative damage, and reduced belly sliceability.

An experiment was performed to determine if the addition of different sources of saturated fat would improve belly fat quality in pigs fed a DDGS-based diet. In addition, the hypothesis that the iodine value product (IVP) of the diet can be used to predict backfat IV and belly fat IV of pigs fed diets containing DDGS was tested.

Digestibility of amino acids in corn, corn co-products, and bakery meal fed to growing pigs

Rising costs of traditional swine feeds are causing many producers to look for alternative feedstuffs to deliver nutritional value at a lower cost. The corn milling and fermentation industries, and the human food industry, create co-products which can be fed to livestock.  One of these, distillers dried grains with solubles (DDGS), has been found to be suitable for inclusion in swine diets up to 30%. Other co-products have not been as extensively studied. This experiment was performed to measure the apparent (AID) and standardized (SID) ileal digestibility of crude protein and amino acids in corn gluten meal, corn gluten feed, corn germ meal, hominy feed, and bakery meal in growing pigs and to compare these values to the values observed for DDGS and corn.

Reduced feed costs with use of DDGS

By Dr. Hans H. Stein

January, 2011

Although the cost of DDGS has increased during the last 6 months, there are still significant savings associated with the use of DDGS in swine diets. DDGS will replace corn, soybean meal, and inorganic phosphorus sources in diets fed to pigs. Because the costs of these ingredients have increased more than the cost of DDGS, it is a good idea to include DDGS in the diets to help reduce feed costs. With current prices for corn, soybean meal, and DDGS, costs of swine diets are reduced by 7 to 9 dollars per ton for each 10% DDGS that are included in the diets (Figure 1). In most cases, 30% DDGS can be included in diets fed to all categories of pigs if an average or above average quality of DDGS is used and if diets are properly balanced for all nutrients. If 30% DDGS is included in diets fed to sows, weanling pigs, and growing-finishing pigs, the total cost savings by using DDGS is approximately 10 dollars per market pig produced.

Digestibility of dietary fiber in distillers coproducts fed to growing pigs

Fiber digestibility is one factor in the efficiency of energy utilization in fibrous feed ingredients. Fiber can be digested via fermentation in the ileum or in the hindgut.

Fecal matter and ileal digesta from pigs fed one of 29 different diets were analyzed to measure the apparent ileal digestibility (AID) and the apparent total tract digestibility (ATTD) of dietary fiber in different sources of distillers dried grains with solubles (DDGS) and to calculate hindgut fermentation (HGF) of dietary fiber in DDGS fed to growing pigs.
