There is a paucity of studies on the effect of intrauterine conditions on subsequent progeny
performance in dairy cows. Using a large national data set on Irish Holstein-Friesian dairy …

Maternal lineage effects, probably indicative of mitochondrial DNA (mtDNA) differences, may
be important for milk production and reproductive success in dairy cattle (Bos taurus) …

In this study, maternal effects were described as age of dam at first and second calving, first-
lactation body condition score (BCS) of the dam during gestation, and milk yield of the dam …

Varying degrees of mitochondrial DNA (mtDNA) heteroplasmy have been observed in
nuclear transfer embryos, fetuses, and offspring, but the mechanisms leading to this …

The efficiency of bovine nuclear transfer using recipient oocytes recovered by ultrasound-
guided follicle aspiration (ovum pick-up [OPU]) was investigated. Oocyte donors were …

Bovine mitochondria contain a 16338 nucleotide closed loop of DNA coding for 13
translated genes, 22 tRNA and 2 rRNA and is inherited exclusively through the maternal …

Yaks are well adapted to the harsh climate and hypoxia occurring under high altitude
grazing conditions of the Himalayan Mountains. However, it is unclear to which degree …

The purpose of this study was to estimate the heritability of scrotal circumference (SC) and
semen traits, genetic correlations between SC and semen quality traits, and the effect of …

Milk yield, fat yield, and fat percentage during the first three lactations were studied using
New York Holsteins that were milked twice daily over a 305-d, mature equivalent lactation …

There are some species-specific epigenetic factors present in the oocyte cytoplasm that may
contribute to nucleo-cytoplasmic incompatibilities either immediately after nuclear transfer …
