The studbook of the Andalusian horse comprising a total of 75,389 individuals (6318 of them classified as Carthusians) was analysed in order to ascertain the genetic history of the breed and, specially, to evaluate its genetic variability and the influence of the Carthusian strain in the breed. Although there is no possible way to identify studs acting as Nucleus in the breed, there is a high c...
Functional agro biodiversity defines the exploitation of biodiversity to provide ecosystem services, support sustainable agricultural production and benefit the regional and global environment and the public at large (ELN-FAB, 2009; www.eln_fab.eu). Tracking of animal products back to the breed of origin based on their genetic make-up undoubtedly falls in this category. The aim of this paper wa...
This research paper’s aim was to investigate both the pre-service teachers’ perceptions of their digital competence and if gender, type bachelor’s degree age made opinions different or not. To do so, clustering analysis method employed analyze areas items questionnaires used as a data collection technique. The study group included 291 participants who are now teacher-trainees in Draa-Tafilalte ...
The study of milk production and composition curves in buffalo provides key information about genetic potentials and management related strategy to both breeders and farmers. The objective of this study was to identify of the non-genetic factors of parameters for fitted Wood function on milk fat content (MFC) and milk fat percentage (MFP) curve of Azari and Khuzestan buffalo. The data were...
A commercial problem of increasing concern is the traceability of the breed origin of individual beef cuts. Current methods, based on paper certifications, are vulnerable to fraud. We report the use of DNA profiles from STR loci for inferring the breed source of given specimens, using both our published Breed Genomic Formula (BGF) method (Ciampolini et al., 2000) and an alternative approach bas...
Monthly weights, heights and condition scores and measurements taken at the time of puberty were utilized to estimate effects of breed-type and heterosis on characters related to growth, size and puberty of second-generation heifers of a five-breed diallel involving Angus, Brahman, Hereford, Holstein and Jersey. One group of heifers was maintained on pasture with supplemental feed; two other gr...
High genetic diversity of East Asian village dogs has recently been used to argue for an East Asian origin of the domestic dog. However, global village dog genetic diversity and the extent to which semiferal village dogs represent distinct, indigenous populations instead of admixtures of various dog breeds has not been quantified. Understanding these issues is critical to properly reconstructin...
The objective of this study was to identify morphological measurements that best distinguish Moroccan Barcha and Atlas goat breeds. Ten measurements (body weight - BW, body length - BL, heart girth - HG, withers height - WH, rump height - WH, back length - BAL, neck length - NL, head length - HL, ear length - EL, and ear width - EW) of 876 adult animals of both sexes (547 Barcha and 329 Atlas) ...
