Anatomical Study of the Gastrointestinal Tract in Free-living Axis Deer (Axis axis)

Effect of Sex and Age on Nutritional Content in Wild Axis Deer (Axis axis Erx.) Meat

Simple Summary

Game meat is perceived as more nutritious than meat originating from domestic farm-ranged animal species. However, meat composition is affected by numerous factors, and differences between game species can be found. The aim of this study is to examine the effect of sex and age on the content of macro- and micro-nutrients in meat from axis deer. Sixteen animals were hunt-harvested and assigned to groups according to sex and age. Samples of m. longissumus thoracis were examined to determine proximate chemical, fatty acid, amino acid and mineral composition. Minor differences were found in the analysed traits between sex and age groups. Regardless of sex and age, axis deer meat is characterised as having a high protein and low-fat content, favourable fatty acid composition and ratios. It is a good source of essential amino acids and micro-minerals. As data regarding axis deer meat are limited, the results of this study are a valuable contribution to describing the quality and nutritional composition of meat of different deer species. Axis deer meat can be recommended as a healthier substitute to red meat.

Abstract

The aim of this study is to examine the effect of sex and age on proximate chemical, fatty acid, amino acid and mineral content of axis deer (Axis axis Erx.) meat. Sixteen (n = 16) animals were hunt-harvested and assigned to groups according sex and age (sub-adult and adult). All analyses were made on m. longissimus thoracis sampled between the 9th and 13th ribs. Minor differences in nutritional composition of axis deer meat were found between analysed sex and age groups. Axis deer meat has a high protein (22.8%) and low fat (1.39%) content. Saturated fatty acids accounted for 44.97% and polyunsaturated for 29.66% of the total fatty acids. Ratios of fatty acids were within the recommended values. Glutamic and aspartic acid were the most abundant non-essential, and lysine and leucine the most common essential amino acids. The ratio of essential to non-essential amino acids was <1. Potassium and phosphorous were the dominant macro-minerals, while iron and zinc were the dominant micro-minerals. The results of this study show that regardless of sex or age, axis deer meat can be considered a good source of basic macro- and micro-nutrients, and can be recommended as a substitute for red meat from domestic animals.
