Estimate of the population of preantral follicles in the ovaries of Bos taurus indicus and Bos taurus taurus cattle

Theriogenology, 2011
The number of oocytes recovered from Bos taurus indicus females subjected to ovum pick-up averaged two to four times greater compared to Bos taurus taurus females. The objective of the present study was to test the hypothesis that this difference in oocyte yield was due to more preantral follicles in the ovaries of Bos indicus females. Ovaries (n = 64)

Autism and mild epilepsy associated with a de novo missense pathogenic variant in the GTPase effector domain of DNM1

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView., 2023
Abstract Dynamin 1 is a GTPase protein involved in synaptic vesicle fission, which facilitates the exocytosis of neurotransmitters necessary for normal signaling. Pathogenic variants in the DNM1 gene are associated with intractable epilepsy, often manifested as infantile spasms at onset, developmental delay, and a movement disorder, and are located in ...

Comparative analyses of copy number variations between Bos taurus and Bos indicus

BMC Genomics, 2020
Background Bos taurus and Bos indicus are two main sub-species of cattle. However, the differential copy number variations (CNVs) between them are not yet well studied.

Caracterização do estro de novilhas cruzadas (Bos taurus indicus x Bos taurus taurus) por radiotelemetria

Brazilian Journal of Veterinary Research and Animal Science, 2006
Embora a técnica de inseminação artificial (IA) apresente inúmeras vantagens, no Brasil é empregada em apenas 7% das fêmeas de corte. Falhas na detecção de estros constituem o principal fator limitante para a obtenção de êxito no emprego da técnica.

Cattle phenotypes can disguise their maternal ancestry

BMC Genetics, 2017
Background Cattle are bred for, amongst other factors, specific traits, including parasite resistance and adaptation to climate. However, the influence and inheritance of mitochondrial DNA (mtDNA) are not usually considered in breeding programmes.

Ascertainment Bias in Cattle SNP Arrays and Implications for Multibreed Genomic Predictions. [PDF]

Anim Genet
ABSTRACT Ascertainment bias of SNP for genotyping arrays, where markers are discovered largely in one breed then used to genotype other breeds, can affect scaling and dispersion of genomic breeding values in multibreed genomic evaluations. Detecting and addressing this bias is crucial for robust genetic analyses.
