Carcass Yields and Meat Composition of Roosters of the Portuguese Autochthonous Poultry Breeds: "Branca", "Amarela", "Pedrês Portuguesa", and "Preta Lusitânica".

Poultry meat is an important part of the human diet, and the valorisation of autochthonous breeds is a determinant for the sustainability of the rural areas. The increasing demand for niche products demands for better knowledge of the carcass characteristics and meat quality of these local populations. The present study aims to characterise the roosters' meat from the "Branca" (BR), "Amarela" (AM), "Pedrês Portuguesa" (PP), and "Preta Lusitânica" (PL) breeds.

Epiphitic Microbiome of Alvarinho Wine Grapes from Different Geographic Regions in Portugal.

Geographic location and, particularly, soil and climate exert influence on the typicality of a wine from a specific region, which is often justified by the , and these factors also influence the epiphytic flora associated with the surface of the grape berries. In the present study, the microbiome associated with the surface of berries obtained from ten vineyards of the variety located in different geographical locations in mainland Portugal was determined and analyzed. The removal of microbial flora from the surface of the berries was carried out by washing and sonication, after which the extraction and purification of the respective DNA was carried out.

Evaluation of Antimicrobial Resistance of Different Phylogroups of Isolates from Feces of Breeding and Laying Hens.

Animal and food sources are seen as a potential transmission pathway of multi-drug resistance (MDR) micro-organisms to humans. is frequently used as an indicator of fecal contamination in the food industry and known as a reservoir of antimicrobial resistance genes (ARGs). Microbial contamination as a major outcome for the poultry and egg industry and is a serious public health problem.

Carcass and Meat Quality Traits of Males and Females of the "" Portuguese Autochthonous Chicken Breed.

The "Branca" breed is a dual-purpose Portuguese autochthonous chicken breed, produced in extensive systems and in small flocks, especially in the Entre Douro and Minho regions. A total of 40 birds (n = 20/sex) were slaughtered between 38 and 42 weeks (males) and 110 and 120 weeks (females), and carcass and meat quality parameters were evaluated. The results showed significantly higher weights and differences for males between sexes and pieces ( ≤ 0.

Chemical Composition of the "Galo de Barcelos" (Barcelos Rooster Raw Meat).

Ten roosters produced according to "Barcelos Confraria" rules and ten roosters of autochthonous "Amarela" breed, reared on a similar traditional production system, were analyzed, and the chemical profile of two of the most significant meat portions, breast and drumstick, was determined. The results demonstrated that the "Barcelos" rooster raw meat is rich in proteins (22.3%) and fat (4.
