  Background and Objective: Meeting nutrient requirement of broiler chicks to supply animal protein requirement cannot be overemphasized. Therefore research was designed to determine gut morphometric and ecological response of broiler starter fed varied levels of protein. Materials and Methods: A total of 144 days-old-broiler chicks were used for the study. Broiler standard starter mash with varied protein percentages of 20, 23 and 26%, respectively for treatments 1, 2 and 3 were used. Data were analyzed using ANOVA at α0.05. Results: Except feed conversion ratio (FCR) other parameters measured were significantly different, 26% CP had most efficient FCR (2.85). Average feed intake, daily feed intake, cost per kg feed and cost per kg weight gain increase with increase in the levels of protein. Weight of gut sections of broiler differ significantly (p<0.05) across treatments except oesophagus, proventriculus, duodenum and large intestine. Coliform forming unit of total aerobic microbes (CFU g1) was higher than other identified microbes in the GIT of broiler chicks. Caecum total aerobic plate count and total anaerobic plate count were higher compare to other sections. Enterobacter aerogenes was found in all regions of broiler examined irrespective of dietary protein levels. Salmonella specie also present across the treatments and present in every section except intestinal of broilers fed 26% CP. Lactobacillus species was found common in caecum and intestine of broilers. Conclusion: There is need for broiler farmers to embark on phase feeding to allow fast growing of broilers and sound biosecurity to suppress the growth of the pathogenic microbes.

  A fifty-six (56) days feeding trial was conducted in a completely randomized design to determine the haematological and serum biochemical characteristics of Hacco cocks fed Cocoabean Shell (CBS) supplemented with vitamin E and beta-glucan. Forty (40) cockerels (aged twenty-five weeks) were used. Treatment diets comprised T1 (control) (i.e. 0% CBS); T2 (20% CBS); T3 (20% CBS + Vitamin E) and T4 (20% CBS + Beta-glucan). The haematological parameters determined were Packed Cell Volume (PCV), haemoglobin concentration (Hb), Red Blood Cell Count (RBC) and White Blood Cell Count (WBC). Others included the WBC differential counts-polymorphs, lymphocytes, monocytes and eosinophils. The serum biochemical parameters determined were serum enzyme activities namely Spartate Amino Transferase (AST), Alanine Amino Trasferase (ALT) and alkaline phosphatase. Other parameters were total protein albumin, globulin and cholesterol. Treatment had significant (p<0.05) effect on PCV, RBC, WBC and polymorphs, while Hb, lymphocytes, monocytes and eosinophils were not significantly (p>0.05) affected by the treatment. Cocks that were fed CBS and CBS + Beta-glucan had similar PCV, RBC and WBC and polymorphs with the control group, while those that were fed CBS + vitamin E had lower values for PCV, RBC and polymorphs than the control group. The groups fed CBS + vitamin E had higher (p<0.05) WBC values than other groups. All the serum parameters determined were not significantly affected by dietary treatment. It was concluded that 20% CBS in diets of cocks did not show adverse effect on the blood parameters of the cocks. When supplemented with β-glucan, there was no adverse effect either. However, when supplemented with vitamin E, some haematological parameters were adversely affected.

  An investigation was conducted in a 2 x 4 factorial experiment to evaluate the effect of Cottonseed Cake (CSC) with or without vitamin-E supplementation on the haematological parameters of pre-pubertal rabbit bucks. The experiment involved 8 treatment combinations comprising four CSC levels (0, 5, 10 and 15%) and two vitamin-E supplementation levels (0 and 30 mg/kg diet) denoted as minus (-) vitamin-E and plus (+) vitamin-E. A feeding trial lasted for eight weeks after which blood was collected from the animals and analyzed for Haemoglobin concentration (Hb), Packed Cell Volume (PCV), Red Blood Cell Count (RBC) and White Blood Cell Count (WBC). Analysis of variance showed that CSC had significant (p<0.05) depressing effect on Hb, while WBC values increased (p<0.05) with increasing level of CSC. The PCV and RBC were not significantly affected by CSC. Vitamin-E supplementation did not have significant (p>0.05) effect on the haematological parameters of the rabbit bucks. Interaction effect of CSC and vitamin-E did not affect (p>0.05) HB, PCV and RBC while only WBC was significantly (p<0.05) affected by the interaction effect. It was concluded that CSC had adverse effect on some haematological parameters and that vitamin-E showed a tendency to correct the adverse effect. Probably a higher dose of vitamin-E is required to elicit a greater ameliorative affect.
