<p>The study determined the effect of introducing 50% of protein from the protein feed pool derived from raw chickpea seeds (CPR) instead of 50% of soybean meal (SBM) in the rearing period from day 22 to 42 on the coefficients of nutrient digestibility, growth performance, selected carcass traits, the hematological and metabolic profile of blood, and the quality of femur bones in male Ross 308 broilers. The study was carried out on 200 22-day-old male Ross 308 broiler chicks (initial weight of 756 g) randomly assigned to two groups (n=100 in each group; 5 cages with 20 birds each). All birds were reared for 42 days. They were fed isonitrogenous and isoenergetic pre-experimental starter diet (day 1 to 21) in crumble form and experimental grower-finisher diets (day 22 to 42) in pelleted form. From rearing day 22, SBM male broilers (grower/finisher) were fed diets with 100% SBM as a protein source. In the diet for the CPR group (grower and finisher), the SBM protein was replaced with 50% of CPR-derived protein. During the grower and finisher stage and between days 22 and 42, the CPR group exhibited significant (P=0.032) reductions in feed intake (FI), higher (P=0.043) slaughter yields, high (P=0.044) % share of breast muscles, and reduced (P=0.003) abdominal fat content. The addition of CPR influenced some blood parameters. The level of total protein, urea, and Mg decreased, whereas the activity of alkaline phosphatase (ALP) and aspartate transaminase (ALT ) increased. In the CPR group, an increase in the physical, morphometric, and some strength parameters of the femur (maximum elastic strength – Wy, yielding deformation – dy, bone density index – BDI, and Young’s modulus) was observed. Therefore, CPR may be a promising partial substitute of SBM in broiler nutrition, as it enhances production performance and has a beneficial effect on bone quality.</p>
