Abstract

The effects of dietary α-linolenic acid on growth performance, meat quality, fatty acid composition and liver relative enzyme mRNA expression of growing meat rabbits

Highlights

Numerous studies have illustrated that polyunsaturated fatty acids (PUFAs) have beneficial effects on normal health and chronic diseases, such as regulation of lipid levels, cardiovascular and immune functions
From a nutritional point of view, enrichment of rabbit meat with PUFA n-3 is more interesting (Dal Bosco et al, 2004; Bianchi et al, 2006, 2009; Kouba et al, 2008; Peiretti and Meineri, 2008). It has been con firmed that many enzymes synthesized in the liver and involved in fatty acid synthesis are affected by PUFA, such as acetyl-CoA carboxylase (ACC), fatty acid synthetase (FAS), carnitine palmitoyl transferase (CPT), and so on
added α-linolenic acid (ALA) concentrations had a significant influence on muscle colour of longissimus lumborum (LL), including L*, a* and b*

Summary

Introduction

Numerous studies have illustrated that polyunsaturated fatty acids (PUFAs) have beneficial effects on normal health and chronic diseases, such as regulation of lipid levels, cardiovascular and immune functions Another important action of n-3 fatty acids is that they can play a key role in the prevention and management of several diseases, including coronary heart disease, dyslipidaemia, type 2 diabetes, insulin resistance, hypertension. From a nutritional point of view, enrichment of rabbit meat with PUFA n-3 is more interesting (Dal Bosco et al, 2004; Bianchi et al, 2006, 2009; Kouba et al, 2008; Peiretti and Meineri, 2008) It has been con firmed that many enzymes synthesized in the liver and involved in fatty acid synthesis are affected by PUFA, such as acetyl-CoA carboxylase (ACC), fatty acid synthetase (FAS), carnitine palmitoyl transferase (CPT), and so on. Notwithstanding, reports about the influence of dietary PUFA on ACC, FAS, and CPT are scarce
