Abstract

Biofortification of Meat with Microelements by Biological Dietary Feed Supplements

In the present paper, zootechnical studies on fatteners fed with the new feed supplement formulation based on the soybean meal were undertaken. Soybean meal was enriched with the following microelements via biosorption process: Cu(II), Mn(II), Fe(II) and Zn(II). The concentration of which in the enriched biomass of soya was as follows: 11.7 ± 1.5; 11.9 ± 1 .5; 5.92 ± 0.77 and 9.06 ± 1.18, respectively. Porkers were divided into three groups: control group feed with fodder supplemented with microelement ions in inorganic form, and two experimental groups: E100% where animals were fed with the fodder supplemented with microelements in biological form of enriched soybean meal, that covered 100% demand for microelements, and E125% group where animals were fed with the fodder supplemented with microelements in biological form of enriched soybean meal, that covered 125% demand for microelements. Obtained results demonstrated that the use of biological microelement supplements increased the average daily gain of pigs, while reducing the consumption of feed. Also increased carcass weight and carcass yield compared to the control group was observed. Meat from the experimental groups was classified as class E, and studies of pH and EC confirmed that the meat was of good quality. Also, increased juiciness of the meat and red color component of meat were denoted in the experimental in comparison to the control group. Administration of pigs with biologicallybound microelements, resulted in an increased level of iron in the meat by about 10% at the recommended dosage, whereas at elevated dosages, the meat was richer in all microelements by 4.3 to 20.3%.
