Insemination and fertilization in the seed bug Lygaeus simulans (Heteroptera: Lygaeidae)

open access: yesEuropean Journal of Entomology, 2000
In the laboratory, not all females of the seed bug Lygaeus simulans Deckert, 1985, produced fertilized eggs after copulation: 26.7% of the females were not inseminated and 5% were inseminated but did not lay fertilized eggs; only in 40% of the couples ...

Surgical removal of a perirectal melanoma through sphincterotomy and rectal wall resection in a horse

open access: yesEquine Veterinary Education, EarlyView.
Summary Melanomas are among the most frequent neoplasms in grey horses. Deep perirectal melanomas, however, are uncommon and challenging to excise due to their proximity to the peritoneal reflection. This report describes the successful standing removal of a large (16 × 8 × 6 cm) perirectal melanoma firmly adherent to the dorsal rectal wall in a 19 ...

Dielectrophoretic Microfluidic Device for in Vitro Fertilization

open access: yesMicromachines, 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 ...

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

open access: yesJournal 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.

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

open access: yesJournal 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

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

open access: yesVeterinary 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 ...

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

open access: yesMajallah-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.

Genetic Parameters and Sex‐Specific Architecture of Observed and Latent Fertility Phenotypes in a Closed Breeding Nucleus of an Arctic Salmonid

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Successful reproduction is a key factor for efficient breeding schemes and sustainable animal farming. Aquaculture breeding programs rely heavily on small fractions of selected breeders to yield large production stocks, given the high fecundity typically observed in these species. In Sweden, Arctic charr (Salvelinus alpinus) is a salmonid with
