On-farm phenotypic characterization of indigenous Tswana sheep population in selected Districts of Southern Botswana

Majority of the Kargil sheep populations are indigenous. Very scanty information is available for morphological characterization of Purky sheep population. Therefore, the present study was undertaken with the objectives to study the morpho-metric characteristics and body measurements for phenotypic characterization of the local sheep. A stratified random sample survey was conducted on various parameters (horn size, tail size, chest girth, punch girth, body length, height at wither and body weight) in seven different age groups. Data were collected randomly from 510 sheep of either sex. The local sheep population of Kargil which was selected for the present investigation is named as ‘Purky’ by the name of the community that reared this breed. In Purky sheep white body colour was predominant in both the sexes. The sheep breed was of low to medium body weight. The chest girth, punch girth, height at withers of Purky sheep showed it to be medium sized. Sex had significant effect (P is less than 0.05) on height at wither only. For males the least squares means were higher for all the traits of all age groups baring few exceptions. The phenotypic correlations of age groups with different morpho-metric traits were very high. The phenotypic correlations of body weight with other body measurements like tail size, chest girth, paunch girth, body length and height at wither were very high. Further studies should be carried out to fully exploit their genetic potential and to register the breed and in-situ conservation of this population.

On Farm

Morphometric data was collected on 859 naturalized swine in Brazil (Piau, Tatu, Nilo, Caruncho, Casco de Burro, Moura, Monteiro and Rabo de Peixe), Colombia (Criolla Zungo, Sanpedreño and Casco de Mula) and Uruguay (Mamellado), both on farm and in published material. Information was collected on breed, sex and age, as well as various morphometric measurements. Analysis of variance was carried out using PROC MIXED of SAS ® on phenotypic data. The coefficients of variance varied between 11.50 and 83.81%, and the coefficient of determination was medium to high. Females were in general smaller for most measurements than males, showing sexual dimorphism. The Moura was the closest naturalized breed to the commercial breeds, followed by the Piau, while the Monteiro was the furtherest. The dendrogram obtained from morphological information showed a division of the pigs into three groups. Characterization was possible using morphological and morphometric data.
