5. INTRODUCTION contd....
Justification
• There is need to understand the socio economic characteristics and husbandry practices
of goat keepers to improve goat production.
• There is need for a detailed phenotypic characterization for conservation and genetic
improvement purposes for West African Dwarf Goats (WAD) in Nigeria.
• Limited reports on phenotypic characterization of WAD Goats are available in the
literature and thus, this will provide additional information. 5

6. INTRODUCTION contd....
Objectives of the Study are to:
• describe the socio economic characteristics of goat keepers in the
study area;
• identify the problems and constraints faced by goat keepers in the
study area and;
• Assess some phenotypic traits of West African Dwarf Goat under
village conditions. 6

7. MATERIALS AND METHODS.
•Study Area
The study was carried out in three villages namely; Ilawo, Araromi and
Isundurin in Ejigbo Local Government Area, Osun State, Nigeria.
• Design of Interview
This study was carried out with the use of structured Questionnaires:
Primary field data were collected through the use of structured
questionnaires with open and closed-ended questions.
• Collection of Data
The morphometric data collected include: Body length(BL), Height at
Rump(HR), Chest Girth(CG),Height at Wither(HW), Ear Length(EL),
Head Length(HL) , Tail Length(TL), Leg Length(LL) Body
Scores(BS) and Live Body Weight(LBW)

9. MATERIALS AND METHODS contd….
• Sampling Procedure
Eighty five (85) Goat keepers were selected from the study area (Ilawo,
Isundunrin, Araromi) based on goat production potentials and willingness
to participate in the study.
• Statistical Analysis
Data collected with questionnaire and through visual appraisal were
analyzed using SPSS (version 20.0) software package and Data from
morphometric measurements were analyzed using the multivariate
components of PAST software (Hammer et al.2008).

19. CONCLUSION
• It was discovered that goat is reared by all group of people irrespective
of Religion, Age, Sex, and Social status in goat production.
• It could be concluded from the results obtained in this study that the
morphometric traits that best describe the morphology of goats in
villages under study are Chest Girth(CG),Height at Wither(HW) and
Height at Rump(HR)

20. RECOMMENDATION
•I recommend that selection should be practiced in the
study area to ensure genetic improvement and
elimination of undesirable characters.
•More studies should be carried out on a larger scale to
obtain larger data . 20
