Limited Utility of a Test‐Yolk Buffer Semen Extender for Preserving Human Semen Parameters for Use in a Diagnostic Setting

Andrology, EarlyView.
ABSTRACT Background Identification of a preservation medium that accurately retains semen parameters would be advantageous for men requiring semen analysis by allowing them to produce sperm samples at home rather than on site or even facilitate ‘mail order’ semen analysis.

The Effect of Cholesterol‐Loaded Cyclodextrin and Resveratrol Compounds on Post‐Thawing Quality of Ram Semen

Veterinary Medicine and Science
Ram sperm are more vulnerable to freezing than those of most other farm animals. During sperm freezing, the cell membrane loses some of its cholesterol, which regulates signalling mechanisms and prevents premature capacitation.

Does synchronising follicular wave emergence improve outcomes in non‐superstimulated donor cattle undergoing ovum pick‐up (OPU) for in vitro embryo production?

Australian Veterinary Journal, EarlyView.
In vitro embryo production (IVEP) is now a widely commercialised assisted reproductive technology used in cattle reproduction. The use of follicle‐stimulating hormone (FSH) to superstimulate donor cattle prior to ovum pick‐up (OPU) is generally regarded as an effective strategy to improve oocyte quality, developmental competence and increase embryo ...

Effects of Resveratrol-Loaded Cyclodextrin on the Quality Characteristics of Ram Spermatozoa Following Cryopreservation

Animals
This study investigated the effects of pure and methyl-β-cyclodextrin loaded forms of resveratrol (10 µg/mL, 20 µg/mL, and 40 µg/mL) on ram sperm functions post-thawing. Semen samples were pooled and divided into ten groups: Control, RES10, RES20, RES40,

Impact of Female Mating Status on Male Courtship Behaviour in a Sexually Cannibalistic New Zealand Fishing Spider

Ethology, EarlyView.
Scoring of male courtship behaviour in Dolomedes minor revealed no effect of female mating status on courtship duration or sequence structure, but males delayed the initiation of courtship when encountering previously mated females. ABSTRACT The evolution of male courtship rituals has traditionally been attributed to female mate selection, but may also

The effect of green tea extract supplementation in bull semen cryopreservation [PDF]

Kafkas Universitesi Veteriner Fakültesi Dergisi, 2019
This study aims to investigate the effect of catechin (CT), green tea extract, as a supplement to Tris extender on semen quality parameters in frozen-thawed of bull sperm. Ejaculates were taken with artificial vagina from Holstein bulls and divided equal

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

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

Journal 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
