Haematological and serum biochemical indices of broiler chickens fed raw sickle pod (Senna obtusifolia) seed meal
Abstract. A feeding trial was conducted for sixty three (63) days (9 weeks) to evaluate the effects of feeding raw Senna obtusifolia seed meal (RSOSM) on
haematological indices and serum biochemical parameters of broiler chickens. Six experimental diets were compounded for both the starter (23% crude
protein - CP) and finisher (20% CP) phases of growth. The diets were formulated to contain 0, 5, 10, 15, 20 and 25% level of raw Senna obtusifolia seed meal
replacing roasted soya bean weight for weight in T , T , T , T , T and T respectively. The 0% replacement level (T1) served as the control diet. The broiler 1 2 3 4 5 6,

chickens were managed on deep litter pens of 30 birds/2.22 m , weighed and randomly allotted to the six (6) dietary treatments in a randomized complete block
design (RCBD). Each treatment group consisted of thirty (30) broiler chicks replicated three times with ten (10) broiler chicks per replicate. Blood samples were
collected from the wing vein at the end of the experiment using standard procedure and were analysed for haematological and biochemical profile. The
outcome of this study revealed that the haematological indices were not significantly (P>0.05) affected by the dietary treatments. However, the blood chemistry
was significantly (P<0.05) affected by the experimental diets. The total protein, albumin, globulin, and some electrolytes components were observed to be
significantly (P<0.05) depressed as the level of RSOSM increased in the experimental diets. For instance, total protein was observed to reduce from 6.24g/dl in
T1 to 3.6g/dl in T6. Electrolyte constituents such as calcium were similarly observed to reduce from 6.01 mmol/l in T1 to 1.15 mmol/l in T6. The serum enzymes
and bilirubin were elevated as the level of RSOSM increases in the experimental diets. Aspartate amino transferase (AST) for instance increased from 8.27U/l
in T1 to 23.18 U/l in T6. It can be concluded that incorporation of RSOSM beyond 5% in the diets of broiler chickens has adverse effects on blood parameters
especially the biochemical parameters
