Determination of net energy in U.S. soybean meal fed to group-housed growing pigs

Soybean meal (SBM) is the major source of amino acids in diets for swine throughout the world. However, in addition to providing indispensable amino acids to diets, SBM also provides energy to the diets. Diets are often formulated based on the net energy (NE) in each individual ingredient using a linear programming computer software. Therefore, the NE for each ingredient is important for the value the ingredient is assigned in the formulation. However, the NE for SBM that is used by most feed formulators was generated many years ago, but results of recent research indicate that current U.S. SBM may provide more NE than previously estimated, which potentially results in an increased estimation of the value of SBM in diets for pigs. There is, therefore, a need for confirming or updating the NE value for SBM. As a consequence, the objective of this experiment was to test the hypothesis that the NE in U.S. SBM fed to modern genotypes of pigs is greater than the value that is currently used in feed formulation.

Effect of sample preparation method and drying method on the concentration of energy in urine and the concentration of metabolizable energy in diets fed to pigs

To obtain accurate values for metabolizable energy (ME) in diets and ingredients, an accurate estimation of gross energy (GE) in urine is required. Urine samples are often prepared following the freeze-dried cotton-plastic bag method and GE is determined by the ignition of the sample in a bomb calorimeter. However, the concentration of GE in urine can also be determined by dripping urine on a cellulose pellet, which can then be ignited in a bomb calorimeter. Alternatively, energy in urine can be calculated from the concentration of N in urine assuming that all energy in urine originates from N. The latter 2 methods may be less expensive and less time consuming than using the freeze-dried cotton-plastic bag method. Likewise, oven drying instead of freeze drying of samples may reduce time and cost of the drying procedure. However, to our knowledge, no data comparing values for GE in urine and ME in diets among different sample preparation and drying methods are available. Therefore, the objective of this study was to test the hypothesis that there are no differences in GE of urine or ME values of diets among sample preparation methods (freeze-dried cotton-plastic bag, undried cellulose pellet, or N value method). The second hypothesis was that drying method (freeze drying or oven drying) of cotton-plastic bag urine samples from pigs do not influence analyzed the GE in urine or calculated ME in diets.

Digestibility of amino acids in high-oil corn product fed to growing pigs

Corn is a cereal grain that is commonly used as a feed ingredient for swine diets due to its excellent palatability, and it can easily be grown on a wide range of environmental conditions. Conventional breeding of corn has generated a new variety (i.e., high-oil corn; Byron Seeds LLC, Rockville, IN), which is believed to contain more oil and crude protein (CP) than conventional corn. It is, therefore, possible that this high-oil corn may be comparable to other cereal grains and may serve as alternative to corn for pigs. However, there are at this point no data to demonstrate the nutritional value of high-oil corn. Therefore, an experiment was conducted to test the hypothesis that the standardized ileal digestibility (SID) of amino acids (AA) in high-oil corn is greater than in conventional corn.

Amino acid digestibility in cheese co-product, in fish meal, and in HP 300 fed to weanling pigs

Whey, which is a co-product from dairy processing plants that extract fat and protein from milk to make cheese has been used in diets fed to weanling pigs as a source of lactose. Whey powder does not contain much protein because the majority of the milk protein ends up in the cheese during processing. However, cheese co-products, which contain 40 to 50% crude protein may be used in the feeding of pigs but there is limited information about the nutritional value of cheese co-products fed to pigs. Therefore, it was the objective of this experiment to measure the apparent ileal digestibility (AID) and the standardized ileal digestibility (SID) of amino acids (AA) by weanling pigs in a cheese co-product and compare values to those obtained in fish meal and in a source of enzyme treated soybean meal (HP 300).
