Abstract

This study sought to compare the in vitro characteristics of fresh and frozen non-sorted (NS) and sex-sorted (SS) bull spermatozoa. Experiment 1: Holstein-Friesian ejaculates (n=10 bulls) were split across four treatments and processed: (1) NS fresh at 3×106 spermatozoa, (2) X-SS frozen at 2×106...

BACKGROUND: Semen cryopreservation might be influenced by sperm concentration. OBJECTIVES: This study was conducted to investigate the effect of three different semen concentrations [100 (C100), 50 (C50), and 25 (C25) × 106 spermatozoa/mL] on freezability of bull semen. METHODS: On each collection...

Abstract

Frozen semen sample of three HF crossbred bulls stored for 4, 8, 12, 16, 20 and 24 months were used to study the effect of long-term storage on post-thaw characteristics of frozen semen. Three frozen semen straws of same batch from individual bull were thawed at 37°C for 30 seconds; pooled and...

Abstract

The aim of the work was to compare the thawing methods of a cattle insemination dose in relation to bull sperm motility. The experiment was done at insemination doses gained from five breeding Czech Fleckvieh bulls. The insemination doses were thawed by a standard method in water bath, then in a...

AbstractFull Text

Heat shock protein 70 (HSP70) is considered as a gene which affects semen quality traits. The present study attempted to investigate the relationship between the HSP70 expression level and motility of bull sperm during the process of freezing-thawing. Semen samples were collected from 5 QinChuan...

Abstract

This study was conducted to evaluate the effect of different concentrations of Limoneno (S)-(-) (50 µM, 100 µM and 150 µM) in supplementing the diluter of bulls freezing semen. Thirty-six ejaculated from four Curraleiro-Pé-Duro bulls were used for cryopreservation. The cryopreserved spermatozoa...

AbstractFull Text

Aim of study was to examine the impact of thawing temperature on quality parameters of bull's semen. A total of 120 commercial doses of deep-frozen bull's semen, originated from three Simmental bulls, were examined. Semen was thawed at 38°C for 30 seconds (n=60 doses, 20 from each bull) or at 50°C...
