Objective: The study aimed to determine the effect of giving concentrate protein from closed-house (CP-CH) broiler farm waste in rations on the meat quality (physical-chemical) and blood profile of landrace crossbreed pigs.
Materials And Methods: The study used a completely randomized design (CRD) with 3 treatments and 4 replications with 12 finisher-phase landrace pigs with an average body weight of 63.42 ± 2.39 kg. The treatments were: A (control): use of 0% CP-CH + 24% CP-152 concentrate; B: 12% CP-CH + 12% CP-152 concentrate; and C: 24% CP-CH + 0% CP-152 concentrate. The research parameters were meat quality (physical-chemical meat) and blood lipid profile [total cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL), and triglycerides (TGs)].
Results: The results showed that treatment group B obtained physical meat quality (pH, drip loss, cooking loss, and water holding capacity) and meat chemical quality (moisture, protein, fat, and ash content) that were almost the same as the control ( 0.05). By administering 24% CP-CH + 0% CP-152 (C) concentrate, there was a significant decrease in the physical and chemical quality of crossbreed landrace pigs ( < 0.05). Administration of CP-CH at 12%-24% did not affect total cholesterol, HDL, LDL, or blood TGs in landrace-crossbreed pigs.
Conclusion: Giving 12% CP-CH (B) obtained meat quality (physical and chemical) almost the same as the control group. Treatment group C significantly reduced the physical and chemical quality of the meat. Administration of CP-CH at 12%-24% did not affect the blood profile of landrace crosses.

Cultured meat technology represents an innovative food production approach that enables the large-scale cultivation of animal cells to obtain muscle, fat, and other tissues, which are then processed into meat products. Compared to traditional meat production methods, cell-cultured meat may significantly reduce energy consumption by 7% to 45%, greenhouse gas emissions by 78% to 96%, land use by 99%, and water use by 82% to 96%. This technology offers several advantages, including a shorter production cycle and enhanced environmental sustainability, resource efficiency, and overall sustainability.

This study evaluated the performance of a deep-learning-based model that predicted cooking loss in the semispinalis capitis (SC) muscle of pork butts using hyperspectral images captured 24 h postmortem. To overcome low-scale samples, 70 pork butts were used with pixel-based data augmentation. Principal component regression (PCR) and partial least squares regression (PLSR) models for predicting cooking loss in SC muscle showed higher R values with multiplicative signal correction, while the first derivative resulted in a lower root mean square error (RMSE).

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.
