Population genetic structure and milk production traits in Girgentana goat breed

Genetic variability and population structure of Raeini Cashmere goat breed assessed from pedigree analysis

Pedigree information which collected from 1979 to 2012 were used to study the genetic variability and population structure of Raeini Cashmere goat, taking kids born from 2009 to 2012 into account as reference population. Averages of inbreeding coefficients in whole and inbred populations were computed to be 0.04% and 4.41%, respectively. Considering the reference population, average inbreeding ...

Genetic polymorphism at the CSN1S1 gene in Girgentana dairy goat breed

The aim of this work was to evaluate the variability of the as1-casein locus in the endangered Girgentana dairy goat breed in order to define genetic improvement and a conservation program for this breed. The study was performed on 200 dairy goats by means of different PCR protocols. Themost frequent alleles were A (0.590) and F (0.290) followed by B (0.065) and N (0.047).CSN1S1 E allele was id...

lactation curve modeling for milk production traits in mahabadi goat breed

in this research, in order to describe milk production traits lactation mahabadi goat breed, seven statistical functions were fitted using 1665 milk production traits records and 833 body weight records. the milk production traits were milk yield, fat percent, fat yield, protein percent, protein yield, lactose percent and snf percent. these records have been recorded on 123 goats during years o...

Genetic variants of alphas1-CN in goat milk: breed distribution and associations with milk composition and coagulation properties

One dairy goat herd of mixed breeds was investigated for frequency of genetic variants of alphas1-casein (as1-CN) and relationships between the genetic variants, milk composition, coagulation properties, and breed. Milk composition (percent total solids, solids-non-fats (SNF), fat, protein, casein, and as1-CN), genetic variants of as1-CN, and coagulation properties (coagulation time, coagulatio...
