Amino acid digestibility in blood meal fed to weanling pigs

Dried blood meal is commonly used as a high-quality protein source in nursery pig diets. Growth studies have indicated that blood meal can be a better protein source than dried skim milk, fish meal, and soy protein concentrate.  However, the growth effects of blood meal vary across studies; this may be due to differences in protein quality.

Limited data exist on digestibility of crude protein and amino acids in blood meal produced from different species and with different drying methods.  Therefore, an experiment was conducted to measure apparent (AID) and standardized (SID) ileal digestibility of crude protein and amino acids in two sources of blood meal.

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.

Alternatives to fish meal in diets fed to weanling pigs

By Dr. Hans H. Stein

July, 2010

Increased global demand for fish meal has resulted in rapidly increased costs of fish meal during the last 6 month. The recent shutdown of many fish processing facilities in the Gulf area has exacerbated the situation and many producers are no longer able to secure fish meal for their pigs. It is, therefore necessary to look for alternatives to fish meal in diets fed to swine.

Digestibility of amino acids in novel soybean products

Raw soybeans contain antinutritional factors such as trypsin inhibitors (TI) and lectins.  The production of soybean meal involves a heating step, which reduces these anti-nutritional factors. However, conventional soybean meal contains compounds which can cause digestive disturbances in weanling pigs. Soybean meal is therefore limited in pig starter diets. Other protein sources, such as fish meal, casein, and soy protein isolate, are used for young pigs.

Two new soybean products were recently introduced to the U.S. feed market.  Fermented soybean meal (FSBM) and enzyme-treated soybean meal (ESBM) are believed to have a lower concentration of antinutritional factors and a higher concentration of crude protein and amino acids than conventional soybean meal.  They are also believed to be better tolerated by young pigs. However, not much is known about the digestibility of the protein in these two products.

This experiment was conducted to compare the digestibility of amino acids in weanling pigs of FSBM, ESBM, conventional de-hulled soybean meal, fish meal, casein, and soy protein isolate.
