Morphometric and morphological analysis of indigenous Matabele goats of Zimbabwe

Abstract

This study aimed to characterize Matabele goats based on their qualitative and quantitative traits, to facilitate their genetic improvement and conservation. Data were collected from 120 goats over 12 months, comprising 20 males and 100 females using a stratified random sampling approach. Body weight and various body measurements were recorded. Five growth curve estimation models were employed to describe the growth pattern of Matabele goats. Descriptive statistics were computed for both qualitative and quantitative traits. Ttests were conducted to assess the impact of sex on morphometric measurements in different age groups. The results revealed an average body weight of 20.93 kg, with significant sex-related differences (p < 0.05) observed across all quantitative traits. Most goats displayed horned and bearded characteristics, while black and white coat colours were predominant. Among the growth curve models, the Gompertz model exhibited the highest R2 value (0.992). Notably, the study found relatively low average morphometric measurements and body weight for Matabele goats, emphasizing the urgent need for genetic improvement efforts and the development of comprehensive breeding standards for this breed.
