Chemical characterization of kid meat from Moxotó goat and Pardo Alpina x Moxotó crossbreeds

Abstract

The objective of this study was to evaluate chemical composition of kid meat of Moxotó (MOX), ¾ Pardo Alpina x ¼ Moxotó (3/4 PAMOX) and ½ Moxotó x ½ Pardo Alpina (1/2 PAMOX) crossbreed goats. Average age of kids at slaughter was 72 days. Kids were fed with cow milk and a protein supplement. Meat analysis showed average values ranging from 77.80% to 80.25% for moisture; from 15.90% to 19.08% for protein; from 1.12% to 1.21% for fat and from 1.29% to 2.03% for ash. For mineral composition, average values ranged from 5.62 mg/100 g to 8.21 mg/100 g for calcium; from 156.97 mg/100 g to 196.25 mg/100 g for phosphorus; from 0.26 mg/100 g to 0.48 mg/100 g for iron; from 16.25 mg/100 g to 23.72 mg/100 g for magnesium; from 59.20 mg/100 g to 78.79 mg/100 g for sodium and from 259.69 mg/100 g to 292.24 mg/100 g for potassium. Genetic groups showed significative differences for composition of moisture, protein and ash values and for mineral composition, in all measured elements. Fat content values did not show statistical differences between goat genetic groups.
