Amino acid digestibility in heat damaged sunflower meal and cottonseed meal fed to growing pigs

Sunflower meal and cottonseed meal can be used in place of soybean meal as protein sources for swine diets. The production of both involves heat treatment, to extract oil from sunflower seeds and cottonseeds and to reduce antinutritional factors. When heat is applied to feed ingredients in the presence of moisture, a series of chemical reactions known as the Maillard reaction may be initiated.  In the Maillard reaction, amino acids and reducing sugars combine to form indigestible compounds known as Amadori compounds. These amino acids are therefore not available to the pigs. Lysine is particularly susceptible to the Maillard reaction. It is important to know the extent of heat damage in feed ingredients so that diets may be formulated that supply the appropriate amounts of digestible amino acids to pigs.

Little information is available about the effects of heat processing on amino acid digestibility in sunflower meal and cottonseed meal. Furthermore, equations to predict the concentration of digestible amino acids in sunflower meal and cottonseed meal from the analyzed nutrient composition have not been reported. Two experiments were conducted to determine the standardized ileal digestibility (SID) of amino acids in sunflower meal and in cottonseed meal fed to growing pigs, and to test if regression equations could be developed to predict the concentration of SID lysine in sunflower meal and cottonseed meal.

Effects of using palm kernel expellers in phase 2 diets fed to weanling pigs

Palm kernel expellers is a coproduct of the production of palm kernel oil. Unlike palm kernel meal, which is produced after the oil is removed from the fruits of oil palms using solvent extraction, palm kernel expellers are produced via mechanical extraction. The lysine content of palm kernel expellers is low relative to soybean meal. Additionally, the high fiber content of palm kernel expellers means that it contains less digestible and metabolizable energy than soybean meal or corn. These factors limit the inclusion rate of palm kernel expellers in swine diets.  However, despite these limitations, palm kernel expellers can provide significant protein in swine diets and may be used to reduce feed costs.

An experiment was conducted to test the hypothesis that palm kernel expellers may replace some corn and soybean meal in phase 2 diets fed to weanling pigs without negatively affecting growth performance.

Concentration of digestible and metabolizable energy and digestibility of energy in high protein canola meal, conventional canola meal, and soybean meal fed to growing pigs

Canola meal is the defatted meal that remains after oil has been extracted from the seeds of the rapeseed plant, Brassica napus.  Canola meal is high in crude protein and amino acids relative to most plant protein sources, and the amino acids in canola meal are well digested by pigs. However, it is also relatively high in fiber, which reduces energy digestibility and digestible energy concentration. New varieties of Brassica napus with a thinner seed coat have been hybridized, which contain less fiber and more protein than conventional rapeseed. The meal produced from these varieties is known as high protein canola meal. No data exist for the digestibility of energy in this source of high protein canola mealwhen fed to pigs. Therefore, an experiment was conducted to determine the apparent total tract digestibility (ATTD) of energy and the concentrations of digestible and metabolizable energy in two sources of high protein canola meal (CM-HP1 and CM-HP2) fed to growing pigs, and to compare these values with values for conventional canola meal (CM-CV) and soybean meal (SBM).
