Effects of different particle sizes of corn on feed efficiency in weanling pigs

Grinding of feedstuffs to small particle sizes is a low-cost way to increase their energy and nutrient digestibility. Currently, nutritionists recommend feeding corn ground to an average particle size of 650 to 700 µm. However, it may be advisable to formulate diets containing corn ground to smaller particle sizes due to the greater metabolizable energy (ME) values of these diets. A previous experiment conducted by Rojas and Stein at the University of Illinois demonstrated that when diets are formulated to contain the same amount of metabolizable energy, feeding diets containing corn ground to different sizes to weanling pigs did not have a negative effect on growth performance.

An experiment was conducted to test the hypothesis that when diets are not adjusted to contain equivalent amounts of metabolizable energy, weanling pigs fed diets containing corn ground to smaller particles sizes will have an improved gain to feed ratio relative to pigs fed corn containing corn ground to larger particle sizes.

Effects of including conventional or high protein canola meals in diets for nursery pigs

Canola meal is a by-product of the canola oil industry. Conventional canola meal contains about 37% crude protein, and is a good protein source for swine diets. New varieties of canola with seeds that contain less fiber and more protein than conventional canola seeds have been hybridized. The meals produced from these new hybrids have a crude protein content similar to that of dehulled soybean meal (Table 1). No data exist on how feeding these high protein canola meals to weanling pigs affects growth performance. Inclusion levels also have not been established for the use of these products in nursery diets.

An experiment was conducted to determine the effect on growth performance of including conventional or high protein canola meals at different levels in diets fed to weanling pigs.

Energy and phosphorus digestibility by weanling pigs of Lemna Protein Concentrate, fish meal, and soybean meal

Lemna Protein Concentrate (LPC) is derived from the leaves of duckweed, one of several rapidly-growing aquatic plants of the genus Lemna. LPC is produced by de-oiling and de-hydrating leaves and stems of the duckweed plant. Duckweed has a number of advantages as a protein source. It is relatively inexpensive to produce and requires less growing area and fewer inputs than other plant protein sources such as soybean products. In addition, LPC has a favorable amino acid profile for use in swine diets. No published data exist on the nutritional value of LPC as fed to pigs. Therefore, two experiments were conducted to determine the concentration of digestible and metabolizable energy and the digestibility of phosphorus in Lemna Protein Concentrate.
