Population genetic structure and milk production traits in Girgentana goat breed

2017

The aim of this work was to evaluate the genetic status of the Girgentana goat, an endangered breed from Sicily (Italy), using microsatellite markers. Furthermore, as the main purpose of the Girgentana breed is milk production, quantitative milk traits were investigated, including fatty acid profile. Molecular data from CSN1S1, CSN2, CSN1S2, and CSN3 casein genes were also used to infer haplotypes. A total of 264 individuals were collected. Samples of Maltese (n = 41) and Derivata di Siria (n = 33) goat breeds were also used to understand the genetic relationship among breeds. Test-day records for milk production were collected to determine daily milk yield, fat, protein, casein, lactose, a…

Genetic variability of Girgentana goat breed using molecular markers

2014

Assessing genetic diversity of local breeds through the information provided by neutral molecular markers, allows determination of their extinction risk and to design strategies for their management and conservation. The aim of this work was to quantify the levels of genetic variability in Girgentana goat breed using microsatellite markers and genetic polymorphisms at the casein genes. A total of 264 individuals were genotyped for 20 microsatellites, selected as suggested by ISAG and FAO. Moreover, the same individuals were characterized for the casein loci (CSN1S1, CSN2, CSN1S2, and CSN3) using PCR and sequencing protocols. Several genetic diversity indexes were estimated. A total of 130 a…
