BACKGROUND:The high polyunsaturated fatty acids content of rabbit meat predisposes it to oxidative deterioration, which often results in reduced product quality and shelf life. This fact highlights the need to improve the antioxidant status of rabbit meat. This study investigated the effects of dietary supplementation of Allium cepa skin (ACS) on growth, carcass, intramuscular fat, muscle fatty acids, cholesterol content, meat quality, antioxidant status, and sensory attributes of hind leg muscle of rabbits. Sixty-three, 28-day-old, male New Zealand rabbits (654 ± 25 g) were randomly allocated into 21 pens of three rabbits. The pens were randomly assigned to one of three dietary treatments -ACS-0: basal diet (BD) only; ACS-25: BD + 25 g kg −1 ACS; and ACS-50: BD + 50 g kg −1 ACSfor 56 days and then euthanized. RESULTS: Dietary ACS did not affect growth performance and retail cuts of rabbits. Muscle cholesterol was lower (P < 0.05) in ACSsupplemented rabbits than in controls. Dietary ACS lowered (P < 0.05) dissectible fat, intramuscular fat content, C14:0, C16:0, C18:0, C18:2n−6, and C20:4n−6 levels and enhanced (P < 0.05) C18:3n−3, C20:5n−3, C22:6n−3, and C22:5n−3 concentration. Dietary ACS increased muscle catalase activity in rabbits. Sensory qualities, malondialdehyde and carbonyl contents, and physicochemical attributes of hind leg muscle of rabbits after chill storage were not influenced by dietary ACS supplementation. CONCLUSION: Supplementation with 50 g kg −1 ACS reduced intramuscular fat and cholesterol content and improved muscle n−3 fatty acids without impairing the physicochemical and sensory properties of rabbit meat.

The influence of dietary oil type (OT) and late feed restriction (FR) on growth, caeca bacteria count, carcass, separable fat depots, serum and muscle lipids, and meat quality in broilers is examined. In total, 224, 21-day-old female Arbor acres broilers are randomly allotted to either PN, Unrestricted+50 g kg −1 palm oil (PO); PR, 25%-FR+PO; SN, Unrestricted+50 g kg −1 soybean oil (SO); or SR, 25%-FR+SO for 21 d. The SN and PR birds have the heaviest and lightest body weight gain (BWG), respectively. Feed conversion ratio (FCR) is poorer in the PN birds. Feed-restricted birds have more caeca Lactobacillus and lower Salmonella, serum cholesterol, and triglycerides. Carcass yield is higher in SR birds and lower in PN birds. The FR-OT interaction is significant for muscle lipids and weight of fat depots. The PN birds deposit more abdominal, intramuscular, sartorial, mesentery and neck fats, muscle saturated fatty acids, and C18:1n-9 and lower C18:3n-3 and C20:5n-3 than other birds. Neither OT nor FR affects the pH, color, water holding capacity, and oxidative stability of breast meat. The changes elicited by 25%-FR on BWG, FCR, carcass yield, depot fats, and muscle lipids in female broilers are dependent on dietary OT. Practical Application: Fast growth rate and unrestricted access to feed can predispose broiler chickens to excessive fat accretion, which is counterproductive. Producing high-quality carcasses that meet consumers' expectation is crucial for sustainable and efficient broiler production. The possible interaction between dietary OT and late quantitative FR in mitigating excessive fat accretion and altering production indices in female broilers is explored. Late quantitative FR reduces BWG, FCR, serum lipids, caeca pH and Salmonella spp. and fat accretion in fat depots, and enhances carcass yield and caeca Lactobacillus spp. However, the impacts are more pronounced in the PO birds than the SO birds. Late FR improves the C18:3n-3 and C18:2n-6 contents in PO meat while reducing the C14:0 and C16:0 contents in SO meat. These findings explicate that dietary OT and late quantitative FR can be synergistically used to mitigate excessive fat accretion and alter growth, caeca microflora, and muscle lipids in broilers.The ORCID identification number(s) for the author(s) of this article can be found under

Sustainable meat production is important to providing safe and quality protein sources for humans worldwide. Intensive artificial selection and high energy input into the diet of many commercial animals for the last decade has significantly increased the daily gain of body weight and shortened the raising period, but unexpectedly decreased the meat quality. The gastrointestinal tract of animals harbors a diverse and complex microbial community that plays a vital role in the digestion and absorption of nutrients, immune system development, pathogen exclusion, and meat quality. Fatty acid composition and oxidative stress in adipose and muscle tissue influences meat quality in livestock and poultry. Recent studies showed that nutraceuticals are receiving increased attention, which could alter the intestinal microbiota and regulate the fat deposition and immunity of hosts to improve their meat quality. Understanding the microbiota composition, the functions of key bacteria, and the host-microbiota interaction is crucial for the development of knowledge-based strategies to improve both animal meat quality and host health. This paper reviews the microorganisms that affect the meat quality of livestock and poultry. A greater understanding of microbial changes that accompany beneficial dietary changes will lead to novel strategies to improve livestock and poultry meat product quality.
