Relationship between somatic cell score and fat plus protein yield in the first three lactations in Spanish florida goats
(MDPI, 2024)
The aim of this study was to estimate genetic parameters of somatic cell score (SCS) and fat plus protein yield (FPY) using repeatability (RM) and random regression (RRM) models in Florida goats. The data consisted of ...
Challenging selection for consistency in the rank of endurance competitions
(BioMed Central (Springer), 2020)
Control of the environmental variability by genetic selection offers possibilities for new selection objectives for productive traits. This methodology aims at reducing heterogeneity in productive traits and has been applied ...
Genetic inbreeding depression load for morphological traits and defects in the Pura Raza Española horse
(BioMed Central (Springer), 2020)
Background
Inbreeding is caused by mating between related individuals and is associated with reduced fitness and performance (inbreeding depression). Several studies have detected heterogeneity in inbreeding depression ...
Genetic inbreeding depression load for fertility traits in Pura Raza Española mares
(Oxford Academic, 2021)
Fertility is a key factor in the economic success of horse farms. However, it has received little attention due to the difficulty of measuring fertility objectively. Since its studbook creation (1912), the Pura Raza Española ...
Prediction of adult conformation traits from shape characteristics of Pura Raza Español foals
(Elsevier, 2021)
Horse conformation has been proposed as an indirect indicator of performance, since their genetic correlations are often positive and high. In Pura Raza Español (PRE) horses, the selection of conformation traits more related ...
Genetic Parameters of Somatic Cell Score in Florida Goats Using Single and Multiple Traits Models
(MDPI, 2022)
A total of 1,031,143 records of daily dairy control test of Spanish Florida goats were used for this study. The database was edited, and only the records of the first three lactations were kept. The final database contained ...
Selection Criteria for Improving Fertility in Spanish Goat Breeds: Estimation of Genetic Parameters and Designing Selection Indices for Optimal Genetic Responses
(MDPI, 2021)
The aim of this study was to estimate genetic parameters for several female fertility criteria and to choose the most suitable selection index in Spanish Florida and Payoya goat breeds. In this study, we analyzed as fertility ...
Survival analysis of productive life in Florida dairy goats using a Cox proportional hazards model
(Wiley, 2023)
Longevity is an economically important trait, since extending the functional life of a doe would allow us to keep the most productive females in the herd as long as possible, and this could result in the increased profitability ...
