Abstract

The objective of this study was to investigate morphometric variation of Minahasa horses. Body measurements and live-weight were taken on 195 mare and 310 stallion of Minahasa horse. A multivariate approach was adopted to provide description of both body shape and body size of four Minahasa local horse populations, i.e. Tomohon, Manado, South Minahasa, and Minahasa. Statistical methods employed in this study were general linear model, simple discriminant analysis, and principle component analysis were used to construct phylogenic trees. The results showed that Tomohon’s horse population had higher body weights and body measurements (P<0.05) than those from three other areas (Manado, South Minahasa, and Minahasa). The hip width is the most discriminant variable to determine the differences among Minahasa local horse population. The results support establishment of strategy to promote the use and the development of local adapted horse.

Abstract

Study was conducted in the regency of Minahasa to estimate horse live weight using its chest girth, body length and body volume formula (cylinder volume formula) represented by animal chest girth and body length dimensions, particularly focused in Minahasa local horses. Data on animal live weight (LW), body length (BL), chest girth (CG) and body volume were collected from 221 stallions kept by traditional household farmers. Animal body volume was calculated using cylinder volume formula with CG and BL as the components of its formula. Regression analysis was carried out for LW with all the linear body measurements. The data were classified on the basis of age. Age significantly (P < 0.05) influenced the body measurements except animal body length (P>0.05). Animal live weight was predicted by simple regression models using dependent variable (Y) of the animal live weight and independent variable (X) of the animal body measurement, either body length, chest girth, or body volume. The correlations between all pairs of measurements were highly significant (P < 0.01) for all age groups. Regression analysis showed that live weight could be predicted accurately from body volume (R2= 0.92) and chest girth (R2= 0.90). Simple regression model that can be recommended to predict horse live weight based on body volume with their age groups ranging from 3 to ≥10 years old was as follow: Live weight (kg)= 5.044 + 1.87088 body volume (liters). The analyses of data on horse chest girth, body length and body volume formula provided quantitative measure of body size and shape that were desirable, as they enable genetic parameters for these traits to be estimated and also included in breeding programs.
