Association study of the CSN2 gene with milk yield in the Sapera goat

Puntos clave

To assess the impact of the CSN2 gene on milk yield and evaluate additive and dominance effects.
Isolated DNA from 64 goats possessing the CSN2 gene.
Performed genotyping using Sanger sequencing.
Assessed genotype effects through analysis of variance and generalized linear model.
Milk yield is significantly influenced by the CSN2 gene variants.
SNP g.8946C > T impacts milk yield significantly (p < 0.05).
SNP g.8956G > A shows no significant impact on milk yield.
Parity and days in milk significantly affect milk yield (p < 0.01).
CC genotype exhibits a higher milk yield without notable additive or dominance effects.

Resumen

Objective: This research was conducted to assess the influence of CSN2 exon 7 milk production and the additive and dominance effects. Materials and Methods: DNA was isolated from 64 goats that possessed the CSN2 gene and subjected to a polymerase chain reaction and genotyping by Sanger sequencing. Genotype effect can be assessed through analysis of variance and the generalized linear model, which can estimate additive and dominance effects. Results: Dairy traits are greatly influenced by the crucial role played by the CSN2 gene. The influence of SNP g.8946C > T on milk yield (MY) is statistically significant (p A on MY is not statistically significant. Furthermore, the MY of Sapera goats is affected by both Parity (p T necessitates many samples and phenotypes. J Adv Vet Anim Res 2025; 12(4.000): 1211-1216
