Non-linear models were analysed to describe both the biological and commercial growth curves of Segureña sheep, one most important Spanish breeds. We evaluated Brody, von Bertalanffy, Verhulst, logistic Gompertz models, using historical data from National Association Sheep Breeders (ANCOS). These records collected between 2000 2013, a total 129 610 weight observations ranging birth adulthood. The aim this research was establish mathematical behaviour body development throughout breed's life...
Abstract Despite the wide biodiversity of avian species zootechnical interest in Spain, projects aimed at characterizing these genotypes and their products are necessary. External internal egg quality traits were measured 819 eggs laid by hens 10 different genotypes: White, Franciscan, Black Partridge varieties Utrerana, Blue Andalusian, Spanish White-Faced, Andalusian Tufted White varieties, Araucana; Leghorn Lohmann LSL-Classic lineage (commercial hybrid line) hen breeds. After...
This paper studies the genetic importance of growth curve parameters and their relevance as selection criteria in breeding programmes Segureño sheep. Logistic Verhulst functions were chosen for best fit to BW/age this breed; first showed general second individual fit. Live weights 41 330 individuals from historical archives National Association Segureña Sheep Breeders used analysis. The progeny 1464 rams 27 048 ewes study phenotypic derived traits. Reproductive management population consists...
Stemming from The Worldwide Donkey Breeds Project, an initiative aiming at connecting international researchers and entities working with the donkey species, molecularly tested pedigree analyses were carried out to study genetic diversity, structure historical evolution of Andalusian breed since 1980s infer a model situation endangered breeds under remarkably frequent unknown genetical background status behind them. Demographic variability parameters evaluated using ENDOG (v4.8). Pedigree...
Genetic diversity and population structure were analyzed using the historical current pedigree information of Arabian (PRá), Spanish Purebred (PRE), Hispano-Arabian (Há) horse breeds. parameters computed a canonical discriminant analysis was used to determine contributions ancestor breeds genetic Há horse. Pedigree records available for 207,100 animals born between 1884 2019. Nei’s distances equivalent subpopulations number indicated existence highly structured, integrated breed, which is...
This study aimed to develop a tool perform the morphological characterization of Sureña and Utrerana breeds, two endangered autochthonous breeds ascribed Mediterranean trunk Spanish hens their varieties (n = 608; 473 females 135 males). Kruskal–Wallis H test reported sex dimorphism pieces evidence (p < 0.05 at least). Multicollinearity analysis (variance inflation factor (VIF) >5 variables were discarded) white nails, ocular ratio, back length (Wilks’ lambda values 0.191, 0.357, 0.429,...
During the poultry sperm cryopreservation process, an excess of reactive oxygen species is generated resulting in oxidative stress which harms quality avian spermatozoa. To counteract this effect, addition exogenous antioxidants, such as Pectoliv-80A (a by-product olive oil), to diluent interesting. For purpose, 16 roosters belonging Utrerana breed were used. Six semen pools (from six different replicates) divided into four aliquots corresponding concentrations that tested (0, 300, 400, and...
The aim of the present study is to characterize productive capability Utrerana and compare relationships among parameters determining internal external quality egg, through canonical correlation analysis. A flock 68 hens a control group Leghorn (n = 17) were housed individually allow individual identification eggs for assessment egg characteristics. Almost all variables showed differences when both breeds compared, except white height, yolk diameter, yolkL* pH (p > 0.05). Only minor yolkL*,...
Despite Ecuador having a wide biodiversity of zootechnical species, characterization studies these genetic resources are scarce. The objective this research was to perform the biometric Creole hen population through 14 quantitative zoometric measures. We evaluated 207 hens and 37 roosters from Ecuador's three agro-ecological regions: Sierra (highlands) region (Bolivar, Chimborazo, Tungurahua Cotopaxi provinces); Costa (coastal) (Guayas); Oriente Amazonian (Morona Santiago). Sexual dimorphism...
The present study aims to develop a statistical tool for turkey breed traceability testing based on meat and carcass quality characteristics. To this end, comprehensive meta-analysis was performed, collecting data from total of 75 studies approaching attributes 37 strains landraces since the late 1960s. A 22 traits were considered variables, grouped in following clusters: dressing traits, muscle fiber properties, pH, colorimetry, water-capacity texture-related attributes, nutritional...
The genetic diversity and population structure of the Spanish Murciano–Granadina goat breed were assessed by pedigree data analysis, which is essential for addressing conservation improvement programs. We analysed 24,444 records (797 males 23,647 females), distributed across 49 herds, period from 1992 to 2006. average generation interval based on age parents at birth offspring was 2.77 ± 1.33 years. Although study did not identify a bottleneck (fa/fe = 1.00), 50% variability provided only...
This study aimed to compare Utrerana native hen eggs' sensory properties Leghorn Lohmann LSL-Classic lineage's commercial and ecological eggs through free-choice profiling. Second, affine non-affine profiles were defined using the information provided by professionally-instructed panelists on six sets (sensory attributes, diet habits, production context awareness, product consciousness, cuisine applicability panelist attributes) nonlinear canonical correlation analysis. Sixty-four instructed...
The present research aimed to determine the differential clustering patterns of carcass and meat quality traits in local chicken breeds from around world develop a method productively characterize minority bird populations. For this, comprehensive meta-analysis 91 documents that dealt with study through last 20 years was performed. Thirty-nine were sorted into following clusters: weight-related traits, histological properties, pH, color water-holding capacity, texture-related flavor...
Sperm cryopreservation is effective in safeguarding genetic biodiversity avian species. However, during this process, spermatozoa are very susceptible to plasma membrane peroxidation the presence of high concentrations reactive oxygen species (ROS). To mitigate effect, addition exogenous antioxidants, such as hydroxytyrosol (3,4-dihydroxyphenylethanol; HT), an antioxidant derived from olive oil, sperm diluent, could be useful. verify this, a diluent was supplemented with different (0 μg/mL,...
Albuminuria and reduced glomerular filtration rate (GFR) are markers of renal dysfunction associated with hypertension. We performed genome-wide scans to detect loci impacting these parameters in 1251 African American (AAs) 1129 European (EAs) hypertensive siblings from the Hypertension Genetic Epidemiology Network study.GFR, estimated by Modification Diet Renal Disease equation, albuminuria, measured as albumin creatinine ratio (ACR), were adjusted for gender, age, centre, mean blood...
SPSS model syntax was defined and used to evaluate the individual performance of 49 linear non-linear models fit lactation curve 159 Murciano-Granadina goats selected for genotyping analyses. Lactation shape, peak persistence were evaluated each using 3107 milk yield controls with an average 3.78 ± 2.05 lactations per goat. Best (Adjusted R2) values (0.47) reached by five-parameter logarithmic Ali Schaeffer. Three main possibilities detected: non-fitting (did not converge), standard R2 over...
