【 摘 要 】

The objective of this study was to estimate the variance components, genetic parameters, and the individual effect of eight single nucleotide polymorphisms (SNPs) in the corresponding genes (αS1-casein (CASA1), β-casein (BCAS), αS2-casein (CASA2), κ-casein (KCAS), α-lactoalbumin (LAA), β-lactoglobulin (LAG), growing hormone (GH), and prolactin (PRL)) in the milk production of Siboney de Cuba cattle at 305-d of lactation.  In total, 1904 lactation records of 913 cows from 17 farms were analyzed under a repetability model. The minisequencing technique was used for uncovering the polymorphism in genes. The eight loci studied had a polymorphic behavior. The heritability and repeatability coefficients estimated for milk production were 0.12 and 0.33 at 305 days. LAG (p≤0.05) and PRL (p≤0,10) loci had a significant effect on milk production. Such coefficients were moderate, indicating that it is possible to obtain a positive response to selection in this population. The selection for both the LAGAA and PRLBB genotypes will result in cows having a higher milk production
