INTRODUCTION
• Between the third and second
centuries, migrators brought early
Iron Age communities into the
eastern parts of South Africa
• One group of the Iron Age people
came down the east coast to
Natal.
• Brought sheep and cattle which
are suspected to be the ancestors
of the Nguni breeds

INTRODUCTION
• The Nguni sheep of Zululand are
called Zulu sheep
• Swaziland: Swazi sheep
• Zulu sheep are found in the
communal areas of KwaZulu-
Natal
• Research flocks: Makhathini

INTRODUCTION
• For many decades, indigenous
genetic resources have been
perceived as unproductive and
inherently inferior to high
performance or improved breeds
• Consequently: subjected to cross-
breeding or even replacement
with exotic breeds
• Rapid decline in numbers of the
indigenous breeds

INTRODUCTION
Not enough information available on
characteristics of Zulu sheep
Need to document Zulu sheep
genetic and phenotypic resources
and to design and implement
strategies for their sustainable
conservation.
Traditional farmers in developing
countries manage their livestock
according to their indigenous
knowledge.

• Support for research on indigenous
knowledge and

INTRODUCTION
The objectives of the present study were:
• To obtain information on the utilization, socio-
economic and cultural values by the farmers
using the Zulu sheep breed;
• To preliminary characterise and estimate
phenotypic variation within the Zulu sheep
breed using six morphological characteristics;
• To estimate the live weight prediction
equations of the Zulu sheep breed using
some body linear measurements and;
• To assess the genetic variation within this
breed.

MATERIALS AND METHODS
1. Intra and inter- population
phenotypic and genetic
diversity was expressed as
dendograms using complete
linkage of Minitab (1998)
2. The regression and Pearson
coefficients procedures of
Minitab Inc. (1998) were used
for the analysis
3. ANOVA: GLM of Minitab
(1998)
RESULTS AND DISCUSSION
• 20% total income per annum:
generated from livestock
• 3.5 % of the total income from
livestock was obtained from
sheep sales
Use of sheep:
i) Source of food
ii) Sometimes given to relatives as
presents
iii) Payments of penalties
iv) Sales when there is need
