Morphological defects in Turkey semen

The goal of this study was to evaluate the abnormal spermatozoa rates and types of American Bronze turkeys under Turkish conditions. Semen was collected from toms by abdominal massage and pooled once a week for 10 weeks. After pooling, the semen samples were examined morphologically and mean abnormal rates and types were evaluated. A total abnormal spermatozoa rate of 17 +/- 0.06% was determined. Acrosome and mid-piece defects were the leading defects at 66 +/- 0.36%. Tail defects of 22 +/- 0.18% and head defects of 11 +/- 0.11% were the next most prevalent

The effects of various BSA levels in different media on development in in vitro culture of mouse embryos

Various BSA (bovine serum albumin) levels and media effects on development of 2-cell stage mouse embryos in in vitro culture were investigated in this 2 stage study. In the first stage, 1400 2-celled mouse embryos were cultured in 2 various BSA-bearing culture media for 96 h and directly observed microscopically. In the second stage, 1024 2-celled mouse embryos cultured for the same period and cell numbers (nuclei of cells) were determined by staining techniques
