Background Since the initial development of in vitro embryo production, the technique has been applied successfully to many species for clinical, commercial, and research purposes. In the early days, it was common practice to supplement culture media with serum to support embryo development in many species. But subsequently, serum has been associated with fetal overgrowth in ruminants to give the ...

INTRODUCTIONPostpartum uterine disease is the leading cause of reproductive inefficiency in dairy cattle (Barlund et al., 2008). Dairy cattle farmed in intensive systems, commonly acquire microbial contamination of the uterus during parturition (Sheldon et al., 2008). Almost all dairy cows (80 to 100%) experience bacterial intrauterine contamination immediately after calving (Herath et al., 2006; ...

1. Introduction.Subclinical endometritis (SCE) is one of the most important reproductive impairments in dairy cows studied in the last decade. It can be defined as the superficial inflammation of the endometrium (no deeper than the stratum spongiosum) [1], without visible clinical signs, but significantly affecting reproductive performances [2,3]. Cytology is considered the best technique to diagn ...

1. IntroductionUterine disease in cattle causes economic losses due to reduction of pregnancies per insemination, extended calving to conception intervals and increased culling rates(Gilbert et al., 2005). Postpartum uterine diseases can be classified as puerperal metritis, clinical metritis, clinical endometritis and subclinical endometritis (SCE; Sheldon et al., 2006). Subclinical endometritis i ...
