Effects of dietary leucine and tryptophan supplementation on serotonin metabolism and growth performance of growing pigs

Tryptophan is an indispensable AA that is often limiting for growth in pigs fed corn-soybean meal-based diets. Tryptophan may act as a regulator of feed intake by enhancing serotonin signaling in the brain, because Trp is a precursor for serotonin. High Trp intake increases feed intake, and this is partly attributed to increased serotonin synthesis. Availability of dietary Trp in the brain is considered the rate-limiting step in hypothalamic serotonin synthesis. However, to be transported into the brain, Trp competes with other large neutral AA such as Val, Leu, Ile, Tyr, and Phe for a common transporter (L-type AA transporter 1) to cross the blood-brain barrier.

Digestibility of amino acids is greater in soybean expellers than in soybean meal when fed to growing pigs

When soybeans are crushed, the oil may be solvent extracted and the resulting defatted soybeans are known as soybean meal (SBM). However, the oil may also be mechanically expelled from the beans and the defatted soybeans resulting from this procedure is an ingredient known as soybean expellers. The expelling procedure is less efficient in removing oil from the beans and soybean expellers, therefore, contain more residual oil than SBM. Soybean expellers can be produced using different technologies, and a new procedure involving a patented high shear dry extrusion procedure was recently developed (Insta-Pro International, Des Moines, IA). There are however, no data for the digestibility of amino acids (AA) in the soybean expellers that are produced from this procedure. Therefore, the objective of this research was to test the hypothesis that the standardized ileal digestibility (SID) of crude protein (CP) and AAis greater in soybean expellers than in SBM when fed to growing pigs.

Digestibility of energy and phosphorus and concentration of metabolizable energy in a new source of high-protein distillers dried grains fed to growing pigs

Recently a high-protein distillers dried grains (HP-DDGS; ProCap DDGS, Marquis Energy, Hennepin, IL) was developed and the HP-DDGS has greater concentrations of CP and fat, but contains less fiber compared with conventional DDGS, which may affect the digestibility of energy and P and concentrations of DE and ME. There are, however, no data for the nutritional value of this new source of DDGS. Therefore, 2 experiments were conducted to test the hypothesis that concentrations of DE and ME, and standardized total tract digestibility (STTD) of P in HP-DDGS are greater than in conventional DDGS.
