Approaches to increase reproductive efficiency in artificially inseminated dairy cows
Infertility has been linked to numerous factors in high producing dairy cattle in the last decades. The detection of estrus continues to present difficulties and, although progress has been made in regards to estrus synchronization and artificial insemination, the reproductive performance of dairy cows has not improved substantially. Moreover, in warm countries, summer heat stress is a major fa...
متن کاملConception rate of artificially inseminated Holstein cows affected by cloudy vaginal mucus, under intense heat conditions
The objective of this work was to obtain prevalence estimates of cloudy vaginal mucus in artificially inseminated Holstein cows raised under intense heat, in order to assess the effect of meteorological conditions on its occurrence during estrus and to determine its effect on conception rate. In a first study, an association was established between the occurrence of cloudy vaginal mucus during ...
متن کاملWhen Should Dairy Cows Be Inseminated?
INTRODUCTION Reproductive efficiency of the dairy herd is important for the economic success of the dairy operation. One of the most important reproductive technologies of the dairy industry is artificial insemination (AI). Artificial insemination reduces the incidence of sexually transmitted diseases among cattle and increases the use of genetically superior sires to improve performance of the...
متن کاملAchromobacter xylosoxidans in extended semen causes reproductive failure in artificially inseminated sows and gilts
Achromobacter xylosoxidans, a Pseudomonaslike bacterium, contaminated a boar stud laboratory’s water distillation and delivery system that was used for extension of raw semen for artificial insemination. In sow herds that used the contaminated semen, conception rates decreased and vulvar discharges, culled sows, and nonproductive sow days increased. Thorough diagnostic testing revealed that A x...
متن کاملMolecular Characterization of Sperm Antigens with In Vivo Developed Antisperm Antibodies in Variably Inseminated Cross Bred-Heifers/Cows
Molecular characterization of sperm proteins and their immunoreactions to sera from subfertile/infertile animals may give deeper insight to the immunological reason of infertility. The purpose of this study was to characterize antigenic sperm proteins by reacting with blood serum and cervical mucus of variably inseminated heifers/cows using immunoblotting and immunofluorescence techniques. Immu...
