The main objective of the present experiment was to determine the metabolizable energy of
Nigella sativa or cumin seed meal. 16 leghorn cockerels aged 31 weeks old were divided
into a completely randomized design with 4 treatments of 0, 10, 20 and 30 percentage of N.
sativa with 4 replicates (1 cockerel each). The birds were adapted to the new diets for 3 days
and then they were starved for 24 h. Cockerels were fed the experimental diets for 72 hours
and the excreta were collected and analysed for gross energy, crude protein, crude fibre …

Introduction The protein sources in poultry nutrition are the most expensive parts of rations.
Today, soybean meal is the major protein source that using in poultry nutrition. The cost of
soybean meal is expensive and search to find new source of protein for poultry diet is
important. Nigellasativa meal is a protein that could be used in poultry nutrition. The Nigella
sativa or cumin seed meal has an acceptable percentage of crude protein, crude fiber, ether
extract and metabolizable energy. The amino acid profile of nigella sativa meal is better than …
