Genealogical structure of the Colombian Romosinuano Creole cattle [PDF]
Tropical Animal Health and Production, 2023 AbstractThe Romosinuano cattle breed is one of the most important Creole genetic resources in Colombia, and interesting traits like adaptation or reproductive efficiency have promoted its use in different countries in America. To consolidate the genealogical historical records, the review of very first yield records in this population was used to ...

Genetic Background and Inbreeding Depression in Romosinuano Cattle Breed in Mexico [PDF]
Animals, 2021 The ultimate goal of genetic selection is to improve genetic progress by increasing favorable alleles in the population. However, with selection, homozygosity, and potentially harmful recessive alleles can accumulate, deteriorating genetic variability and hampering continued genetic progress.

Allelic and genotypic frequencies of SNP related to beef and carcass quality in Romosinuano cattle in Mexico [PDF]
Tropical Animal Health and Production, 2023 Abstract Romosinuano is a tropically adapted Bos taurus breed, and some Mexican breeders look to improve it genetically. The aim was to estimate allelic and genotypic frequencies for SNPs associated with meat quality in a Mexican Romosinuano population. Four hundred ninety-six animals were genotyped using the Axiom©BovMDv3 array.

Economic utility of Colombian Romosinuano cattle [PDF]
Tropical Animal Health and ProductionAbstractThe objective of this study was to quantify the economic utility in Romosinuano production systems by developing a bioeconomic model assumed cow-calf, cow-calf plus stocker (CCPS), and complete cycle operations. Each system produced males for sale and females for replacement.

Gene Expression of Aquaporins (AQPs) in Cumulus Oocytes Complex and Embryo of Cattle [PDF]
Animals, 2022 Aquaporins (AQPs) are proteins with various functions related to proper cell function and early development in mammals. The aim of this study was to evaluate the presence of AQPs and determine their mRNA levels in the cumulus oocyte complex (COC) of four

In Vitro Embryos of Romosinuano and Tropical Milking Cattle during Three Seasons in Veracruz, Mexico [PDF]
AnimalsOne of the main factors that influences the fertility of cattle in grazing systems in hot tropical climates is heat stress. The objective of this study was to evaluate the effect of season, breed, hormonal and physiological condition on the quantity and quality of cumulus–oocyte complexes (COCs) and embryos produced in vitro, from Romosinuano (RM) and ...

Genomic Analysis of Taurine and Indicine Ancestry in the Montana Tropical Composite Population. [PDF]
J Anim Breed GenetABSTRACT The Montana Tropical cattle, a Taurine and Indicine composite, were developed in Brazil since 1994 and were based on crossing four biological types of cattle: zebu (mainly Nelore), tropical adapted taurine (mainly Senepol and Romosinuano), British taurine (mainly Angus) and continental taurine (as Charolais, Simental and Limousin).

Identification of Reference Genes for Expression Studies in the Whole-Blood from Three Cattle Breeds under Two States of Livestock Weather Safety [PDF]
Animals, 2021 Real-time PCR is widely used to study the relative abundance of mRNA due to its specificity, sensitivity, and repeatability quantification. However, relative quantification requires a reference gene, which should be stable in its expression, showing ...
