Biochemical composition of high protein feeds from white lupine and the effect of antioxidant on their storage life

The paper presents data on the biochemical composition of seeds and the amino acid composition of leguminous crops, white lupine. It was found that the content of crude protein in white lupin grain is higher than in other leguminous crops. The fiber content averages 13.21%, and this indicator must be taken into account when using white lupine for poultry feed, since the fiber content in poultry feed should not exceed 10-11%. Lupin is inferior to soy in terms of fat content and, accordingly, linoleic acid in seeds, but surpasses other legumes. The biochemical composition was determined in concentrates obtained by various technological methods, according to the main zootechnical indicators, in addition, the amino acid content and carotene content were evaluated. The content of dry matter, crude fat, calcium and phosphorus increases in granular and extruded ESPC compared to white lupin grain. The crude fat content in the ESPA is significant, and its indicators for granular feed are 11.68%, and for extruded feed 14.21%. The results of the use of the antioxidant Agidol in the composition of manufactured feeds and its effect on its shelf life are described. The CSF values of the extruded feed were within the normal range both in the control and in the experimental samples with Agidol until the end of the shelf life. But if at the beginning of the experiment the lipid oxidation indices in the control and the prototype were almost equal – 5.0 and 4.75 mg / g KOH, then by the end of the fourth month the difference between the control and the variant with an antioxidant was more than 20%. In granular feeds, these indicators were higher. At the beginning of the experiment, in the control of CSF was 10.36 mg/g KOH, and in samples with Agidol – 10.19 mg/g KOH, then by the end of the shelf life 20.49 and 14.43 mg/g KOH respectively. The difference between the images of the feed without an antioxidant and with it was 30%.
