The net economic value of reproductive efficiency in dairy cattle was estimated using a
stochastic dynamic simulation model. The objective was to compare the economic …

This study was aimed at determining the median days of calving to conception interval (days
open) and identifying the major risk factors determining the days open in dairy cows. Both …

Trends since 1980 for calving age and calving interval, 2 factors that influence herd life,
were examined by parity for 5 breeds of US dairy cattle. Calving data were from cows with …

Background A retrospective cohort study using a 10 year artificial insemination (AI) and cow
reproductive performance data was conducted to study the success rate of AI; associations …

Inbreeding depression on female fertility and calving ease in Spanish dairy cattle was
studied by the traditional inbreeding coefficient (F) and an alternative measurement …

The objective of this research was to evaluate the relationship between udder health and
reproductive performance in UK dairy cows. Data from 80 herds were restructured such that …

Epigenetic regulation in mammals begins in the first stages of embryogenesis. This prenatal
programming determines, in part, phenotype expression in adult life. Some species …

The objective of this paper was to study some factors affecting reproductive performance of a
locally-born Friesian herd in Egypt. Data of 2096 reproductive records representing 482 …

Genetic correlations among female fertility traits (linear and binary) were estimated using
225,085 artificial insemination records from 120,713 lactations on 63,160 Holstein cows …
