Abstract

Soybean is one of the best sources of plantbased proteins for animal feed production. The products that remain after soybean processing are used as food for humans and as raw materials for the food, chemical and pharmaceutical industries. Soybean production depends upon a number of factors including adequate soil, light, moisture and selected variety. Soybean is a good source of protein, oils, carbohydrates, minerals, vitamins and essential and non-essential amino acids.Antinutritional substances (thermolabile and thermostable) are also present in soybean seeds.These are not digestible and/or have a negative effect on digestion and cause slower growth of
animals. However, with appropriate technological processing, these substances can be partially and/or completely inactivated. Laboratory analysis can show whether processing has been adequately performed and whether the antinutrient values are within the appropriate range. Analysis of soybean seeds and soybean products in the Feed Analysis Laboratory, Poultry Centre, Croatian Veterinary Institute in Zagreb, Croatia showed certain variations in nutritional content. Variations were in respect to the origin of samples (data were not always provided with the sample) or were not in concordance with the declaration (if available) or with the data listed the table of chemical composition and nutritional values. Basic chemical parameters, including mineral content, were determined in all samples using standard analytical methods. Analysed parameters were moisture, ash, crude fat, crude fibre, crude protein, sugar, protein solubility in 0.2% potassium hydroxide, minerals (Ca, P, Na, Mn, Cu, Zn, Fe, Mg, and K), chlorides soluble in water, trypsin inhibitor and urease. The aim of this study was to compare the quality of soybeans and soybean products (nutritional content) from different sources that are available in Republic of Croatia and to evaluate their potential for use as animal feed.
