Research Reports

Energy concentration in canola, cottonseed, and sunflower products fed to growing pigs

Soybean meal is a high quality source of protein for swine diets. Due to the growth in global production of pigs and poultry, demand for soybeans is increasing rapidly, outpacing production. Therefore, other sources of plant protein are sometimes used in diets to supply indispensable AA to the animals.

The most abundant oilseeds produced in the world, aside from soybeans, are cottonseed, canola seed (rapeseed), and sunflower seed. These oilseeds may be fed as de-oiled meals, or the full fat seeds can be fed to increase the energy concentration of the diet.

There are no recent data on energy digestibility in canola, cotton, and sunflower products. Therefore, an experiment was conducted to measure the digestible energy (DE) and metabolizable energy (ME) in canola seeds (CS), canola meal (CM), cottonseed meal (CSM), sunflower seeds (SFS), sunflower meal (SFM), and dehulled sunflower meal (SFM-DH), and to compare these values to the DE and ME in soybean meal (SBM).

Digestible and metabolizable energy concentration in 4 sources of canola meal and in soybean meal fed to growing pigs

Due to the increasing demand for protein for livestock feeding, the interest in using canola meal in diets fed to swine is increasing. Canola meal is a product of the rapeseed plant, an abundant oilseed crop grown in Canada, the Northern United States, and parts of Europe. Recently, new varieties of canola that contain more protein and less fiber than conventional canola have been selected. The de-oiled meals of these varieties have a concentration of crude protein that is close to that of de-hulled soybean meal.

It has been speculated that changes in the traditional pre-press solvent extraction oil removal procedure may improve the quality of canola meal. The traditional procedure involves use of heat to desolventise the de-oiled meal, but a new procedure allows for production of canola meal using a low-temperature procedure.

There is no information about the digestibility of energy in high protein canola meal. There also is no data comparing the digestibility of energy in canola meal processed at low temperatures versus high temperatures. Therefore, an experiment was conducted to compare the concentrations of digestible energy (DE) and metabolizable energy (ME) in high protein, high-temperature-processed, low-temperature-processed, and commercial canola meals, and to compare these values with the DE and ME in corn and soybean meal.
