albumin to globulin (alb/Glb) ratio similarly showed significant changes (P < 0.05) with the treatments although there was no particular trend. Total serum protein concentration
was not adversely affected by replacement level of up to 75% CSC for SBC protein in the diets.Beyond this replacement level a depression in the utilization of protein was observed. Reddy and Salunkhe(1984) reported decreases in total protein attributable to
inhibition of protein utilization in broilers. However, the 75% replacement of SBC protein with CSC is an indication of the efficient use of the protein in the diet, Chandra
et al. (1983) and Adejinmi et al. (2000) made similar observations even though their values were slightly lower.The Total protein, Albumin and Globulin values recorded in this study attest to the nutritional adequacy of CSC in meeting the protein needs of the birds except those in treatment 5. The candid observation from this work shows that 75% CSC protein can conveniently replace the same amount in SBC in a properly formulated
diet to meet the nutritional needs of the broiler birds.
Carcass analysis
Results of carcass characteristics are shown in Table 9.Significant (P < 0.05) differences in weight gain were observed at the end of the study. Live weight ranged from 1.60 to 2.10 kg. However, on the average treatments 2, 4and 1 (control) had higher weights than the other
treatments. The bled weight expressed as percentage of the live weight did not show any significant difference (P< 0.05). Values ranged from 96.88 to 98.97 %. The plucked weight expressed as percentage of live weight showed significant differences (P < 0.05) among treatments.Values for plucked weight ranged from 86.88 to 92.30 %. The dressed weight also expressed as a percentage of the live weight ranged from 65.63 to 73.33
%. The value for treatment 5 was significantly (P < 0.05) lower than all the others. The gastro-intestinal tract (GIT),liver, heart, gizzard and all other body parts measured
