The objective was to evaluate the performance, carcass and meat quality of 40 lambs classified by RFI (residual feed intake) and RIG (residual intake and gain). Dry matter intake (DMI) was recorded to calculate the RFI and RIG, classified as efficient, moderately or inefficient. After the confinement period, they were slaughtered and the carcass and meat quality were determined. The efficient animals had DMI scores of 0.700 RFI and 0.400 kg/d RIG, lower than the inefficient ones with similar weight gain. The RFI efficient animals showed greater shear force, without effect in the RIG classification. In general, the variables analyzed were not influenced by RFI or RIG. Efficiency measures do not affect the carcass and meat quality of sheep, but they do have the advantage of identifying animals with lower feed consumption, making the system more efficient. However, as the dataset is limited to fully assess the effects, this manuscript can be used as preliminary results for future studies.

The purpose of this study was to explore the effects of changing the digestible energy (DE) level of the diet on the growth performance, intestinal function, carcass traits, meat quality and blood biochemical indices of Ningxiang pigs, and to comprehensively identify the lipid molecules in the abdominal fat of Ningxiang pigs through lipidomics technology to evaluate the pork quality. The experiment selected 225 castrated Ningxiang pigs (47.64 ± 0.

The objective of this study was to evaluate the effect of dietary inclusion of different carrot forms on production results, carcass traits, meat quality, fatty acid (FA) composition, vitamin content, and feed costs in Cherry Valley broiler ducks. A total of 240 one-day-old males (initial body weight of 55.2 g) were allocated to 4 treatments (n = 60; 6 replicates of 10 birds): control (CD; 100 % commercial diet), CFL (CD + 2 % carrot flakes), RAWC (80 % CD + 20 % raw carrot), and CPOW (CD + 2 % carrot powder).

This study evaluated the effects of raising systems and diet types on growth performance, carcass characteristics, pH content, fatty acid profiles and meat quality in Japanese quail (Coturnix japonica). A total of 608 seven-day-old quail chicks were arranged in a 2 × 2 factorial design, with two raising systems (cage and free-range) and two diet types (conventional and organic). The experiment employed a completely randomized design with four treatments, four replicates per treatment, and 38 birds per replicate.

Human listeriosis is a severe food-borne illness, with fatality rates ranging from 20 to 30 %. In Brazil, despite being an underdiagnosed and underreported disease, the presence of the microorganism in food has been the subject of important studies. However, its occurrence in slaughterhouse environments has received little attention in recent years.

Alternatives to the use of chemical antimicrobials to treat meat and poultry carcasses during processing and food processing environments are of interest to consumers globally. The influence of bacterial cell concentration, membrane permeabilizing agents, and effect on macromolecules of the photosensitizer curcumin (PSC) on Salmonella inactivation in a medium model and on chicken skin and the inactivation of Listeria monocytogenes biofilms on stainless steel were determined. The addition of 30 mg/mL CaCl or higher significantly reduced the level of Salmonella compared to PSC treatment alone in a liquid media system.
