Theriogenology Flashcards
Quirox -Castro - BoHV-1 virus detection in genital organs
2019
BoHV-1 detected in utrerus of all seroporitive cows. Virus not detected in seronegative cows.
FIlho- pregnancy associated glycoproteins for PD at 24d
2020
Serum conc of PAG at day 24 >0.33ng/ml and >0.54 in heifers was 95% accurate for PD status at day 30
Heifers that had late embryonic death had lower PAG levels at day 24 - didnt work for cows
Sefi-Jamadi - Seasonal differences on semen quality and embryos BB bulls
2019
Higher sperm conc at lower THI (volume,motility, total output not affected)
Freezethawed semen - motility affected, viability and velocity were lower in high THI
De Lima - Induction of puberty long acting P4 injection
2020
Induction with P4 hasten puberty and lead to preg success in prepubertal heifers like pubertal heifers
Schlegl - Post insemination cepharin IU
2020
Cepharin tx 6h post AI didnt alter preg rates
Dahl - MAstitis and parity effects on preg loss
2020
Impact of mastitis on pregancy loss is higher in older cows (parity >3)
Ryan - increased calcium inclusion in acidified pp diet = better uterine health and fertility
2020
Cows fed acidified, calcium supp diet = better uterine environment
Tuska - effect of elective c section on colostrum in BB cows
2021
Primiparous animals- neg impact on colostrum volume
Time in c section = significant effect on colostrum volume
Summer - negative impact on colostrum volume
No significant effects on colostrum quality
Besbaci - NSAID on PR embryo transfer
2021
NSAID = higher preg from ET (15%)
NSAID in hard to pass catheter cows = bigger effect (71%)
Silva - Progesterone profile and follicles using CIDR
2021
Greater circulating P4 with PRID>CIDR
No effect on DF diameter and follicular growth rate
Higher circulating P4 = slower DF growth rate
Romano - Effect of fasting pre EEJ
2021
Fasted group - higher % penis extrusion, erection and ejaculation
Reduction in bladder size
Oliviera - Lepto embryonic death in herds with repro disorders
2021
High seroactivity = more repro problems
Prominance of Sejroe = embryo death, ictohaemorrhagicum = abortion
Loureiro - repro syndrome with lepto?
2020
Poor conception rates
Loureiro - Where does lepto colonise in bovine genital leptospirosis
2020
Uterus
Ianuzzi - Sperm telomere length and association with semen quality
2020
Associated with increased motility and facilitates chomosonal alignment during meiosis
