Dehulling effect of dietary administered white lupine seeds on the blood biochemistry of broilers

Abstract

The aim of the study was to assess the effect of the partial or complete dietary replacement of crude protein (CP) from soybean meal (SBM) with CP from the meal of whole (trial 1) or dehulled (trial 2) white lupine (WL) seeds on the blood plasma biochemical indicators in broilers. Chickens of the control (C) group were fed diets containing the SBM as the main protein source in the feed. It results from the findings that the complete and also partial replacement of CP from the SBM by CP from the meal of whole WL seeds in diets led to a decrease in the plasma cholesterol and triacylglycerides (TAG) levels (P < 0.001). Concerning the dietary administration of dehulled WL seeds, only the complete replacement of CP resulted in a decrease in the plasma glucose and TAG levels in 35-day-old broilers (P < 0.05). In addition, when including the dehulled WL seeds into the diet, an increase in the plasma aspartate aminotransferase activity was found in both the E1 and E2 groups (P < 0.01). Based on the results found, it can be stated that the use of meal from whole WL seeds seems to be a promising protein feed component which has beneficial effects on the health of broilers.
