Guar Meal Can Partially Substitute Soybean Meal In Animal Ration
A high-protein feed stuff showcased by a local distributor at the recent Agrilink trade show can be used to partially substitute soybean meal as an ingredient in animal feed ration. Called processed guar meal, it widely used in other countries and in India where it originated but was introduced to the country only few years ago.
Guar meal is one of the byproducts of the milling of guar gum, says Ana Liza Cuyugan of Centrovet Marketing, Inc., which markets imported processed guar meal under the product name Guarcol.
As a primary product of a fodder plant called guar (Cyamopsis tetragonoloba), guar gum is extensively used as emulsifier, thickener, and stabilizer in food and oil industries. After the gum is extracted, guar meal is processed by toasting the guar seeds at high temperature to remove the natural trypsin inhibitor, thus enhancing its nutritive value and digestibility.
Cuyugan said that guar meal can also be used as a binding agent in feed formulation. It is characterized as free flowing, has light greenish color and coarse texture, 100% non-transgenic, and contains a minimum of 45% oil and albuminoid. More importantly, guar meal is free from salmonella, E. coli, and aflatoxin.
Data provided by Centrovet show that guar meal is comparable to soybean meal in terms of nutritional content. For instance, the minimum crude protein percentage of guar meal is rated at 50% compared to 48% of soy bean meal. Its crude fiber is at 6.8% maximum, while that of soybean meal is at 3%; It has a minimum crude fat content of 5% versus 1% of soybean meal, and has a higher protein solubility of 89% than soybean meal with 78%.
Analysis for amino acids also showed that guar meal has 3.22% lysine, 0.79% cystine, 1.94% threonine, 3.62% arginine, 3.7% leucine, 0.73% methionine, 1.51% meth+cystine, 0.68% tryptophan, 2.31% isoleucine, and 2.35% valine. It has metabolizable energy of 3,450 k/cal for swine and 2,520 k/cal for poultry.
When mixed with feed formulation, guar meal can be given at 5% to 7% of total feed production for layers. In broilers, the recommended inclusion rate is 5%-7% for starter feeds, and 5%-12% for grower feeds.
For swine, the following dosages are recommended: 5%-7% (pre-starter), 59% (starter), 5%-12% (grower/finisher), and 5%-10% (breeder).
Guar meal is also suitable for use in ruminant feeds at a rate of 5%-7%, and for aquaculture feeds at 10%-20%.
Cuyugan added that processed guar meal is also cheaper by P3-P4 per kilogram (kg) than soybean meal. At current market price, guar meal is sold at P23 per kilogram and comes in 50-kilogram packaging.
By the way, Centrovet also distributes soya milk protein concentrate and a high-grade fishmeal made from pure anchovy fish which are also high-protein sources for poultry, swine, and aquaculture.
