Abstract

The study was conducted to assess the effects of sweet potato leaves, roselle calyces and beetroot tubers on body weight, selected hematological and biochemical parameters in broiler chickens. Eighty four (84) broiler chickens aged four weeks were randomly assigned into six groups of 14 chickens each. The first group (G0) remained as untreated control while the other groups were the treated groups which received 25% of ground sweet potato leaves (G1), rosella calyces (G2), beetroot tubers (G3) and their mixtures (G4 and G5) for 28 days. Following inclusion of these different vegetables, blood samples were collected and analyzed for selected hematological and biochemical parameters on day 0, 7, 14, 21 and 28. Results showed that consumption of the three vegetables caused significant decreases (p < 0.05) in body weight, serum glucose and cholesterol. On the other hand, hemoglobin concentration, packed cell volume (PCV) and total white blood cell (WBC) counts were shown to increase significantly (p < 0.05) compared to the control group. It is concluded that the hypoglycemic and hypocholesteremic effects in chickens following consumption of the three vegetables together with their positive effects on PCV and WBC counts are important qualities which can be utilized in the management of conditions such as obesity, diabetes mellitus, hyperlipidemia and cardiovascular diseases (atherosclerosis and coronary disease) in humans. Further studies in other animals are recommended.

Highlights

Haematological and biochemical parameters are important tools in diagnosing the structural and functional status of the animal’s body (Elagib and Ahmed, 2011)
Mean body weights of chickens in G0 and G1 increased gradually (p < 0.001) throughout the experimental period compared to other experimental groups
The current study assessed the effect of selected botanicals on the body weight, hematological and biochemical parameters in broiler chickens

Summary

Introduction

Haematological and biochemical parameters are important tools in diagnosing the structural and functional status of the animal’s body (Elagib and Ahmed, 2011). These parameters can be influenced by several factors including; nutritional factors (Etim et al, 2014), environmental factors (Vecerek et al, 2002); (Graczyk et al, 2003), diseases and age (Talebi et al, 2005). There are important plants with nutritive importance which are yet to be studied and utilized (Antia et al, 2006). Plants such as sweet potatoes (Ipomea batata), roselle (Hibiscus sabdariffa), beetroot (Beta vulgaris) and burn (Aloe vera) among others have been used for decade and claimed to possess several effects on body weight and blood parameters
