Dielectrophoretic Microfluidic Device for in Vitro Fertilization

Micromachines, 2018
The aim of this work was to create a microfluidic platform that uses in vitro fertilization (IVF) and avoids unnecessary damage to oocytes due to the dielectrophoretic force manipulation of the sperms and oocytes that occurs in a traditional IVF ...

Application of Genomic Random Regression Models for Genetic Parameter Estimations of Female Fertility Traits in Different Parities in German Holsteins

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT The aim of the present study was to infer genetic (co) variance components and to estimate parity‐specific breeding values for the female fertility traits non‐return rate after 56 days, the interval from calving to first service and days open by applying random regression models on a time‐dependent parity scale. In this regard, we considered a

Precursor A-Kinase Anchor Protein 4 as a Predictive Biomarker of Post-Thaw Semen Quality in Goats

Veterinary Sciences
The evaluation of sperm proteins has emerged as a promising approach to predicting semen quality across animal species. This study investigated the relationship between post-thaw concentrations of precursor A-kinase anchor protein 4 (proAKAP4) and ...

Efficacy of hCG and GnRH with Respect to Follicular Size and Presence of the Corpus Luteum in Cosynch Protocol Integrated with Norgestomet in Lactating Cows

Journal of Veterinary Research, 2013
Efficacies of hCG and GnRH with respect to follicular diameter in Cosynch protocol were investigated. Lactating cows (n=119) received injections of GnRH and PGF2 7 d apart.

Genetic Evaluation of Beef Sires Using a Beef‐on‐Dairy Crossbred Reference Population

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT In recent years, Beef‐on‐Dairy (BoD) crossbreeding programs have gained momentum to enhance dairy cattle's economic and genetic merits while meeting the demand for high‐quality beef. However, bulls with superior growth potential can lead to calving problems; thus, Holstein dairy farmers must decide which semen to use to avoid calving problems ...

Evaluation of the Efficacy and Side Effects of Catheter-Specific Intrauterine Insemination in Infertile Couples, a Randomized Clinical Trial

Majallah-i Dānishgāh-i ’Ulūm-i Pizishkī-i Shahīd Ṣadūqī Yazd, 2022
Introduction: Intrauterine insemination (IUI) is one of the assisted reproductive techniques, which increases the likelihood of egg being exposed to sperm in the uterus and thus the chances of pregnancy.

Genomic Analysis of Inbreeding Depression on Productive Traits in Rubia Galega Beef Cattle Breed

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT In autochthonous livestock breeds with small populations, such as the Rubia Galega from Galicia (Spain), mating between relatives is common and can lead to inbreeding depression. Genomic inbreeding coefficients were estimated for 4984 animals using ~63,000 SNPs to assess inbreeding depression in four key traits: age at first calving (AFC) with

Potential of the Predatory Mites Gamasellodes lavafesii (Mesostigmata: Ascidae) and Cosmolaelaps mediocuspis (Mesostigmata: Laelapidae) on Different Soil Pests/Parasites and Alternative Prey for Large‐Scale Rearing

Journal of Applied Entomology, EarlyView.
ABSTRACT Many species of Mesostigmata soil mites have potential as biological control agents of pests/parasites. This study evaluated the predation potential of two of these species, Gamasellodes lavafesii (Ascidae) and Cosmolaelaps mediocuspis (Laelapidae).
