“…The morphometric measurements show highly significant sexual dimorphism, due to hormonal growth effects [ 39 ], in accordance with several authors [ 17 , 18 , 19 , 20 , 22 , 24 , 40 , 41 , 42 , 43 , 44 ]. Breed had significant effect ( p ≤ 0.05) in males, with the superiority of the “Branca” roosters, being the heaviest, largest and with the highest shank diameter and the “Preta Lusitânica” roosters, the lightest, shortest and with the smallest chest circumference.…”

“…Morphological traits are essential to implement breeding programs and dimensions of certain morphological variables could make them suitable, from a productive point of view, for meat (breast measurement) or egg productions (body and dorsal lengths, head length) [19,22,24,27,37,51]. Autochthonous Portuguese hens present morphological traits which would made them more prone to meat production ("Branca"), although the dimensions of certain morphological variables could make them suitable for doublepurpose production ("Pedrês Portuguesa" and "Amarela") and is important to consider a breeding programs adjustment to underline their productive potential [36,44,46].…”

“…The sustainability of production is becoming an increasingly strong consumer argument for the choice of products and producers that are part of their diet [ 17 , 18 , 19 ]. The breeding system for indigenous species is balanced by the use of natural resources, land and water, making it environmentally “friendlier”, and particularly adjusted in less favored regions where these resources are scarce [ 16 , 20 , 21 , 22 , 23 , 24 ].…”

Promotion of the conservation and preservation of local breed’s biodiversity combined with the concept of sustainable agriculture and development of economically marginal areas are important policies to implement in modern society. The biometric characterization, contributing to maintain phenotypic traits, is a significant tool in breeding programs, which revaluate local breeds, allow the preservation of animal biodiversity and support consumer demands. This paper approaches the biometric characterization of the Portuguese poultry breeds through the study of sexual dimorphism and breed differentiation using six zoometric measures as differentiation criteria. A total of 429 fowl (66 males and 426 females) were studied and the parameters recorded were body weight, body length, chest circumference, shank length, shank diameter and wingspan. A highly sexual dimorphism was evident, in all breeds, with the “Branca” breed being the most zoometrically distant. Concerning Principal Component Analysis, the highly correlations observed between body length, wingspan and shank length, determined the generalized animal form and could be used as selection criteria for improving body size. Breeding programs aiming to preserve these local genetic resources should consider the dual purpose of these breeds: sustainability and cultural legacy, and the offer to urban consumers a source of differentiated high-quality products.

“…Additionally, the numerous research papers available on this issue demonstrate the interest and work being directed towards the protection of these Italian breeds. Proteomic characterization and genetic studies addressing the issues of diversity, breed characterization, and molecular markers have been conducted in relation to the following breeds: Ancona [ 11 , 12 , 13 ], Bianca di Saluzzo and Bionda Piemontese [ 14 , 15 , 16 , 17 , 18 ], Ermellinata di Rovigo [ 7 , 19 , 20 , 21 , 22 , 23 , 24 ], Livorno [ 11 , 12 , 13 , 15 , 25 ], Mericanel della Brianza [ 15 , 26 , 27 ], Milanino [ 15 ], Millefiori di Lonigo [ 19 ], Modenese [ 11 , 12 ], Padovana and Pepoi [ 7 , 19 , 20 , 22 , 23 , 24 ], Polverara [ 7 , 19 , 20 ], Robusta Lionata [ 7 , 19 , 22 , 24 ], Robusta Maculata [ 19 , 20 , 22 , 24 ], Romagnola [ 11 , 12 ], Siciliana [ 15 ], Valdarnese Bianca [ 11 , 12 ,…”

The most reared species of farm animal around the world is the chicken. However, the intensification of livestock systems has led to a gradual increase in the concentration of a limited number of breeds, resulting in substantial erosion to the genetic pool. The initial step of an ‘animal conservation program’ entails establishing the actual conservation statuses of the breeds concerned in a defined area; in this case, in Italy. To this end, a survey of breeds was performed by means of a census questionnaire divided into two parts. The first part collected information on breeds, breeders, housing facilities, and management aspects, the results of which are presented here. The second part of the questionnaire regarded chicken products and their markets, and these data will be reported in a second paper. The breed status of six chicken breeds was shown to be exceptionally worrying, with total numbers ranging from just 18 to 186 birds. Population sizes exceeding 1000 birds was identified for just four breeds, the maximum being 3400. Some improvements in status were noted in relation to breeds which had been the subject of conservation efforts in the past. The two most common breeds reported are the Bionda Piemontese, a double-purpose breed, and the Livorno egg-laying hen. Collo Nudo Italiano, Millefiori Piemontese, Pollo Trentino, and Tirolese chicken breeds and the Castano Precoce turkey breed were not listed by breeders at all. The most reported turkey breeds are the Bronzato Comune and the Ermellinato di Rovigo. The population sizes of native Italian poultry breeds were shown to be generally poor. Italian poultry farmers and the population at large are largely ignorant about indigenous poultry breeds. Thus, promoting the virtues of Italian breeds would help their conservation by encouraging breeders to rear these birds and consumers to buy their products. The identification of strategies to facilitate access to pure breed birds is essential, and will require the collaboration of university research centers, public entities, and breeders. The results presented in this paper constitute the initial part of a more complex conservation program.

“…There are different methods to characterize animals, ranging from linear measurement of morphological traits to the use of molecular techniques [ 15 ]. For example, phenotypic and morphological measurements have been used to characterize and differentiate various chicken breeds [ 16 , 17 , 18 ], and different molecular methods including microsatellites and single-nucleotide polymorphisms (SNPs) have been used to investigate the genetic structure of different chicken populations [ 19 , 20 ]. The most common methods for phenotypic characterization are canonical discrimination and multivariate analyses [ 21 ].…”

Nowadays, the high demand for village chickens in Malaysia leads to the fraudulent substitution of indigenous chickens with other cheaper counterparts. Discriminating different chicken breeds based on their phenotypic characteristics is one strategy to avoid chicken adulteration. The main objective of this study was to authenticate and group dominant chicken breeds in Malaysia, including commercial chickens (Cobb, Hubbard, DeKalb) and cross-bred village chickens (Ayam Kampung, Akar Putra). The further discrimination of village chickens from underaged colored broilers (UCBs) (Hubbard, Sasso) was performed based on phenotype traits. The results showed that the breed had a significant effect (p < 0.05) on phenotypic characteristics, while the sex effect was not significant for some characteristics. In the first phase, the most remarkable discriminating factors were abdominal fat weight, breast muscle weight, chest circumference, shank length, and wingspan. However, in the second phase, notable variations in phenotypic characteristics between village chickens and UCBs were not detected. Principal component analysis (PCA) showed the successful separation of village chickens from high-performance breeds (broiler and colored broiler). Nevertheless, there was overlap among observations for Sasso and village chickens, which approved the possible similarities in their phenotypic characteristics. This study showed clear breed clustering, which leads to the chicken authentication based on their phenotypic characteristics.
