This study compared organic pig meat production with conventional production with regard to carcass- and meat quality traits. 80 crossbred female and castrated male pigs were used [(Swedish Landrace × Swedish Yorkshire) × Hampshire] of which 40 were raised under organic conditions and the other 40 were raised in a conventional production system. The organic pigs were raised outdoors in one large group following the regulations for organic standards. The conventionally raised animals were kept indoors in groups of eight and were given a conventional feed mixture. It was found that meat of organically raised non-carriers of the RN(-) allele was of poorer quality (higher drip loss and increased shear force values) compared with meat from the other animals. The RN genotype had a relatively small effect on carcass and technological traits in this study. The sex of the animals affected carcass traits.

Reducing meat consumption is crucial for improving population and planetary health. Millions of students regularly eat at university cafeterias, which offer a unique opportunity to promote meat-free meals to new generations by addressing barriers such as accessibility, price, and cooking skills. This study aimed to analyse the individual characteristics associated with the proportion of vegetarian main dish choices in a university cafeteria and to determine whether this behaviour influenced the nutritional quality and environmental impact of student meals.

This study aimed to investigate the association between estimated dietary intake of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) and human sperm quality. This study cross-sectionally assessed the associations between estimated dietary intake of PCDD/Fs and sperm quality parameters in 200 participants aged 18-40 years from the Led-Fertyl study. Linear regression models, accounting for potential confounding variables, were employed to evaluate the relationships.

Thirty male Hu lambs (38.95 ± 3.87 kg; 6 months old) were randomly assigned to two groups: (1) SBM (a basal diet with soybean meal) and (2) FSM (a diet replacing 10 % soybean meal with 10 % flax seed meal) to evaluate their effects on Hu lamb production and slaughter performance, meat quality, muscle fatty acid composition, and antioxidant capacity.

This study aimed to identify mRNA isoforms that were expressed differently in the muscle tissue of Nellore cattle based on their intramuscular fatty acid profile. Forty-eight young bulls were used to quantify beef fatty acids (FA) and perform RNA sequencing analysis. The young bulls were divided into three different groups based on quantifying FA using k-means analysis.

Steak samples were collected from the longissimus lumborum muscles of beef carcasses (Canada AA, n = 1505; Canada AAA, n = 1363) over a 3-year period. Steaks were aged for 14 d, and tenderness was determined by slice shear force (SSF). Metabolomic profiling of beef samples was performed using rapid evaporative ionization mass spectrometry (REIMS) (N = 2853).
