Genetic polymorphism of milk protein loci in Argentinian Holstein cattle

Abstract: Some alleles of milk protein loci are associated with superior cheese production characteristics. The genetic polymorphism of the milk protein loci alphas1-casein, beta-casein, k-casein and beta-lactoglobulin was examined in Argentinian Holstein cattle. Samples from 12 herds of four regions of Córdoba were analyzed by starch gel electrophoresis. The chi² test was used to assess whether the populations were in Hardy-Weinberg equilibrium. Genotypic diversity was analyzed by the Shannon-Weaver index. The observed… Show more

“…High frequency of A allele was also observed in Brazilin zebu Gyr, Guzerat and Nelore cattle (Azevedo et al, 2008). Bonvillani et al (2010) and Ren et al (2011) observed a higher frequency of allele A and lower frequency of allele B in Holstein cows. Contrary to these findings, Ceriotti et al (2004) reported that allele B has higher frequency than allele A in B. taurus breeds as compared to B. indicus breeds.…”

“…The estimated frequency of A allele of β LG gene in Holstein breed has been reported by other authors as 0.27 [36], 0.516 [23], 0.52 [24], 0.498 [37], 0.57 [26], 0.43 [38], and 0.52 [35]. However, in other breeds the frequency of this allele was: 0.44 in Brown Swiss [36], 0.37 in Polish Black and White [32], 0.0159 in Kan gayam breed [39], 0.41 in Ayrshire, and 0.68 in Jersey [40], 0.17 in Sahiwal, and 0.36 in Tharparkar [41], and 0.41 in Italian Friesian [42].…”

“…La identificación de la variabilidad genética en estas proteínas resulta de interés para caracterizar el potencial productivo de una población, pues se han reportado asociaciones entre los genes que las codifican y la producción de leche, como así también con el rendimiento quesero y con incidencia de mastitis. Entonces, por relacionarse con la producción láctea tanto desde un punto de vista cualitativo como así también cuantitativo, la variabilidad genética de las principales proteínas de la leche, CSN y LGB, ha sido en años recientes, objeto de gran interés, tanto en bovinos como en caprinos (Bonvillani et al, 2000;Caroli et al, 2007;Chessa et al, 2005;Ikonen et al, 2001;Ramunno et al, 2001). En ovinos, por el contrario la variabilidad genética de las proteínas de la leche ha sido menos estudiada.…”
