Abstract
Background: Morphologic measurements such as body lenght, wither height, heart
girth, chest width, body leght, cannon-bone circumference is used to predict carcass
weight. For this purpose, estimating carcass weight with measurements of key bones
such as ankle bones, which play a significant role in the balance distribution of body
weight, seems possible.
Objectives: The aim of this study is to create new regression models for effective carcass weight estimation by using the morphometric data of the talus and calcaneus
bones of hair goats.
Methods: Study materials consisted of talus and calcaneus bones obtained from abattoir products of hair goat kids (12–18 months old, 20 female and 20 male) and adult hair
goats (36–48 months old, 20 female and 20 male). Morphometric measurements of the
talus and calcaneus of each animal were taken by a digital caliper. Using the morphometric measurements, an index and a factor were calculated for each bone. Regression
analysis and correlations were examined in IBM SPSS 21 programme.
Results: As a result, statistical analysis of GLc, GLt, Bd, Calfactor and Talfactor were
statistically significant on predicting carcass weight.
Conclusion: Specific anatomical structures, such as certain bone measurements, such
as talus and calnaneus could serve as indicators of growth performance and also
carcass weight performance. In addition new anatomical factors and indices may be
produced and new regression methods may be applied with these new parameters to
predict carcass weight.
