Nigella sativa seed oil meal as a source of plant protein in broiler diets

Abstract: This work aims 10 evaluate the possibility of using Nigella seed oil meal (NSOM) as a source of protein in broiler diets. Ninety six, one-day old Arbor Acres broiler chicks were randomly distributed into 24 replicates of 4 chicks each. Nigella seed oil meal protein replaced soybean meal (SBM) protein at 0, 10, 20 , 30, 40 and 50%. 36 chicks were randomly distributed among 6 replicates of 5 birds each and were fed 2 treatment diets based on SBM and NSOM as main sources of protein in the diet.
Chemical analysis of NSOM indicated high percent of protein in, fat, minerals and amino acids. Apparent metabolizable energy (AME) was 3185 kcal/kg and true metabolizable energy (TME) was 3900 kcal/kg. The total protein efficiency suggested that it could be used as a main protein source. The true amino acid availability (TAAA) was higher than apparent amino acid availability (AAAA). Replacing SBM protein by NSOM protein up to 50% did not affect growth. Feed intake and feed conversion ratio (FCR). Dressing percentage, abdominal fat, liver, heart, gizzard and pancreas, intestinal length. WBC's, spleen and Bursa were not affected by NSOM' protein. Also, chemical and physical characteristics were not affected significantly by the level of lNSOM protein.
In conclusion, up to 50 of SBM protein could be replaced by NSOM protein without adverse effect on productive performance. meat quality and immune response of broiler chicks from 1-49 d of age. .
