Tree Species Diversity and Structure of Illo-Kaoje Forest Reserve, Kebbi State, Nigeria

Abubakar Idris Zagga

ABSTRACT

This study was carried out to examine tree species diversity and structure of Illo-Kaoje Forest Reserve. Twenty sample plots (20m×25m) were laid at random within the forest reserve. In each plots, the number and type of tree species were identified and recorded. Diameter at breath height (dbh) and Tree height of each stand was also measured. A total of 568 tree species distributed in 13 families, 27 genera and 31 species were recorded. Vitaleria paradoxa had the highest number of trees (91) followed by Daniellia oliveri (76) while Strichnos spinosa and Nauclea diderrichii had 3 stand each. Shannon Wiener diversity index was 2.92; Species richness 1.30; Evenness 0.85 while Hmax and Density stood as 0.85 and 0.06 respectively. Illo-Kaoje Forest Reserve has a moderate diversity and therefore, the need to manage the existing forest resources for continual production of goods and services is hereby recommended.

ABSTRACT

Newcastle disease poses a serious threat to the poultry industry as it has economic and ecological impact on pet, free living as well as domestic birds. The aim of the study was to evaluate the effects of some antioxidants and Momordica balsamina on haematological parameters in broilers challenged with ND Kudu 113 Virus. Two-hundred-day-old broilers were procured from a hatchery in Ibadan. The chicks were brooded for 4 weeks then divided into 8 groups (1 ml/L) of 20 chicks each. Each group was housed in a pen on deep litter system with a floor space of 1.14 cm² /bird with the exception of G1 which was housed outside the faculty. All the experimental groups except G1 were challenged with NDV Kudu 113 strain but G1 was given 2 ml of distilled water at 5 weeks of age. Birds in G2 were challenged with NDV and not treated with any antioxidant but given 2 ml of water at 5 weeks of age. Birds in G3 were administered vitamin C600 mg tablets in 2L of water at the rate of 2 ml of water per bird orally. Birds in G4 were treated with vit. E 400 mg/ml and challenged. Birds in G5 were treated with selenium-vit Eat I ml/L in 2 L of water /bird orally. Birds in G6 were treated with ethanol extract of M. balsamina leaves 400 mg/ml in 2 L of water orally. Birds in G7 were administered ethanol extract of M. balsamina roots 200 mg/ml in 2 L of water orally. Birds in G7 were administered ethanol extract of M. balsamina roots 200 mg/ml
