Predicting horse skin weight from carcass weight | Predicción del peso de la piel de caballo a cartir del peso de la canal

Parés Casanova, Pere-Miquel
A study was conducted to provide information on the skin weight of Pyrenean horses and to determine whether there is a measurement to predict this based on carcass weight. Hot carcass weight (HCW) and fresh skin weight (SW) were recorded for 58 horses aged 12 months entering a Catalan commercial slaughter facility between September 2009 and June 2010. Data on the breeder, age and coat characteristics were collected and subsequently collated for each animal. Prior to analysis, horses were subdivided into sex and coat groups. Data did not differ (P < 0.001) among these. The absence of differences in SW could be viewed as a reflection of limited nutritional differences between seasons. Regression procedures were used to develop equations to predict SW from HCW. Equations predicting SW had significant bias, 7.3-7.5 kg, and low R2 values. The coefficients of determination obtained for predicting skin weight were not satisfactory and therefore validation was not considered worthwhile.
