Complex vertebral malformation: relationship between carrier status and milk yield in three holstein herds in western Mexico. Complejo de malformación vertebral: relación entre animales portadores what genotype is found in a carrier of a recessive genetic disorder la what genotype is found in a carrier of a recessive genetic disorder de leche en tres hatos de la raza holstein en el occidente de México. Theodor Duifhuis Rivera 1. Clemente Lemus Flores 2.

Jorge Galindo García 1. Complex vertebral malformation CVM is an autosomal recessive genetic syndrome present in Holstein cattle. The disease results in direct economic losses for cattle ranchers due to abortions and deaths of newborn calves. The purpose of the study was to estimate the allelic and genotypic frequencies of CVM syndrome in three Holstein cow herds in western Mexico and determine whether an improving effect between CVM genotype and milk production exists.

The total recessive allele frequency of the CVM was 0. Milk production by lactation did not differ between CVM carriers and normal cows. It is concluded that not a direct relationship was found between milk production and CVM carrier status in the Mexican herds sampled. El complejo de malformación vertebral CVM es un síndrome genético autosómico recesivo presente en el ganado Holstein.

La enfermedad causa pérdidas económicas directas para los ganaderos debido a los abortos y la muerte de becerros neonatos. El propósito del estudio fue estimar las frecuencias génicas y genotípicas del síndrome CVM en tres hatos de vacas Holstein en el occidente de México y determinar si existe un efecto mejorante entre el genotipo CVM y la producción de leche. Se compararon los genotipos de las vacas y los promedios de producción de leche de primera y segunda lactancia ajustados a días utilizando un modelo estadístico mixto, y se calcularon frecuencias génicas y genotípicas.

La frecuencia total del alelo recesivo de CVM fue de 0. La producción de leche por lactancia no difirió entre los portadores CVM y las vacas normales. Se concluyó que no hay una relación directa entre la producción de leche y el genotipo de portador de CVM en los hatos mexicanos muestreados. The mutation provokes the substitution of valine to phenylalanine in amino acid of the protein which inhibits the functioning of uridine diphosphate N-acetylglucosamine UDP-GlcNAca nucleotide-sugar transporting protein residing in where are humans on the phylogenetic tree Golgi apparatus.

This peptide is essential for the control of vertebral formation in the mesoderm, and the defective molecule leads to vertebral malformation Thomsen et al. The defective allele for CVM was spread globally by the over-usage of a high-performance bull, Penstate Ivanhoe Star, and its offspring, Carlin-M-Ivanhoe Bellwhich were both carriers of the deleterious allele Agerholm, The what genotype is found in a carrier of a recessive genetic disorder of this study were to identify cows carrying CVM in three Holstein herds in Western Mexico, to identify any differences in first- and second-lactation milk production between carrier cows and normal homozygotes, and to determine whether the carrier genotype has an improving effect on dairy production.

This study included Holstein cows with two or more lactations from three industrial dairies in the state of Jalisco, Western Mexico. The first, second, and third herds were comprised of, and cows, respectively. If the bp amplified sequence belongs to the wild-type allele, the enzyme cut the fragment into two parts 21 pb and bp ; if it belongs to the mutant allele, there was no cutting site and the fragment will remain complete. What genotype is found in a carrier of a recessive genetic disorder SPSS software, version 20,was used to perform a mixed statistical model in each herd separately, in order to identify differences in first- and second-lactation milk production between carrier cows and what genotype is found in a carrier of a recessive genetic disorder type homozygotes of gene SLC35A3.

A fixed and random effects design was used considering the following mixed statistical model:. Table 1 shows the distribution and frequencies of SLC35A3 genotypes in the three herds. Differences in milk production by lactation among herds, which can be explained by the different environmental and handling factors present in each daily farm, were found.

Milk production did not differ between normal and heterozygous CVM genotypes. No difference in genotype or allelic frequencies was observed among herds. Table 2 Average milk production in kilograms at days per cow, two milking per day, per lactation by genotype and herd. No significant difference in milk production was observed between wild homozygous allele and heterozygous carrier in both lactations.

In the first decade of this millennium, high allelic frequencies of animals carrying CVM, such as 0. However, in the second decade of this millennium, the frequency of the mutant allele of the CVM decreased. The genetic frequency of the CVM mutation in our study was 0. This trend suggests gradual selection against the mutation since the year A literature review revealed no previous study examining associations between dairy production parameters and the SLC35A3 genotype causing CVM.

The CVM mutation was detected in three Mexican Holstein cow herds analyzed in this study, since a direct relationship between milk production and the CVM carrier genotype was not found. The use of molecular marker-assisted selection against CVM will not reduce herd productivity in Holstein-Friesian cattle in Mexico. The implementation of programs to monitor hereditary diseases among Holstein cattle ranches is necessary to avoid the spread and future presentation of genetic diseases.
