The carcass and blood indices of 180 Japanese quails fed diet containing different nutrient quality were examined. The quails were randomly assigned to five treatment groups. Each treatment had two male and two female replicates consisting of nine birds each in a randomized complete block design (RCBD). The feed consisted of a normal diet (2600 Kcal/kg metabolizable energy, ME, 24% crude protein, 5% fat, 6% crude fibre) for treatment one (T1) which was the control while the other diets were deficient or high in one of the nutrients. At the end of the five weeks feed trial, two birds were randomly selected from each replicate for carcass analysis while the blood from the jugular vein was collected for serum studies. The result obtained showed that the diets significantly (P < 0.05) influenced the dressed weight, breast, neck, shank weight and shank length such that the weights were highest in the birds fed the high fat diet and similar to others except in the low energy group which had the poorest weights. The birds fed the high fibre diet had the highest gizzard weight. The birds fed the low energy diet had the lowest packed cell volume and haemoglobin level which was significantly (P < 0.05) different from the others but recorded the highest MCV. The serum total protein, albumin, uric acid, and creatinine were better in T1, T3 and T5 while these parameters were poor in the birds fed the low energy and low crude protein diets. The red blood cells, white blood cells, MCH, MCHC, serum glucose, AST, ALP and ALP were not affected across the treatment groups. It was therefore concluded that low energy and low crude protein diets should not be fed to quails as they were detrimental to the health and carcass production of the birds.
