Introduction: The Cebu Cuba Livestock Improvement Program (PMGC) has a control system based on the individual results of approximately 12,000 purebred females distributed throughout several herds throughout the country. Are recorded in young males, the we... see more

Improvement of sow reproductive performance is a key factor determining the efficiency of the pig production cycle and profitability of pork production. This article presents the solution of an important scientific and practical problem of individual fore... see more

Abstract. Nowadays molecular profiling of dairy animals and the relationships between certain genetic polymorphisms and milk production traits is of great interest. In particular, the polymorphism of the six major milk protein genes was intensively studie... see more

Introduction. The relevance of the study of genetic pathologies is due to the growing prevalence in most countries, disability and mortality of persons, high costs of support and treatment. The modern classifications include various forms of porphyria and... see more

The aim of this study was to estimate the components of (co)variance and genetic parameters for birth weight (BW, n = 16 806), weaning weight adjusted to 240 d of age (WW240, n = 9 011), yearling weight (YW, n = 6 516), age at first calving (AFC, n = 5 97... see more

          The aim of this study was to estimate the coefficients of heritability and genetic correlations among visual scores (conformation, CPW; precocity, PPW; musculature, MPW) and reproductive traits: age a... see more

The study aims to determine the environmental and genetic components for the reproductive performance of a Tunisian local goat population to set up the basis for the future improvement of this important component of efficient production. The reproductive ... see more
