Proximate, Mineral, Fatty Acid and Cholesterol Composition of Five Muscles of an Indigenous Swine Breed of North East India

Background: Ghungroo is the first registered indigenous pig breed of India bearing accession number INDIA_PIG_ 2100_ GHUNGROO_09001 reported from Western Assam and North Bengal. The present study determines nutritional content (proximate, mineral, fatty acid and cholesterol) of five muscles that are considered most valued cuts by customers. Methods: Thirty muscles were dissected from six reared Ghungroo pigs, each from shoulder (Triceps brachii, Latissimus dorsi) and from ham region (Biceps femoris, Gracilis, Tensor fasciae latae). Two months old piglets were reared from October, 2019 to May, 2020 and slaughtered. They were administered commercial diet i.e. starter, grower and finisher feed during different stages of growth. Result: The highest protein, fat and ash were found in tensor fasciae latae, gracilis and triceps brachii respectively (P<0.05). In 100 g of meat, potassium, sodium, magnesium and zinc was found highest in Tensor fasciae latae, Latissimus dorsi and Biceps femoris respectively (P<0.05). The total saturated (SFA's), monounsaturated (MUFA) and polyunsaturated (PUFA) fatty acids were found highest in Tensor fasciae latae and Latissimus dorsi respectively (P< 0.05), while trans-fatty acid and cholesterol were both found highest in Gracilis. The data shall be valuable for muscle specific improvement of meat quality and value addition for global markets.

Automated summary

This study investigated the nutritional content of five different muscles from Ghungroo pigs and found significant differences in protein, fat, ash, minerals, and fatty acid composition among different muscles. The findings provide valuable insights for improving meat quality and value addition.
