This graphical abstract depicts the number of additional fish that would be required to achieve 90% genetic diversity for endangered pupfish species housed in EAZA collections, with or without the use of cryopreserved material. ABSTRACT Zoos and aquaria must retain genetic diversity for the species they house if the populations are to remain viable ...

Improving ARTs: Microfluidics as a Tool for Sperm Selection
ABSTRACT Sperm selection is a critical step in assisted reproductive technology (ART), as sperm quality directly influences embryo quality. In vivo, the female reproductive tract imposes several physical and physiological barriers that favors only the most optimal spermatozoa reaching the fertilization site.

Basal body temperature as a biomarker of reproductive state in ewes: A multi‐method comparison
This study quantified body temperature dynamics throughout reproductive stages in crossbred ewes based on complementary monitoring techniques. Five ewes from a semi‐extensive farming system were included in two sub‐trials: animals were first assessed in the prepubertal stage and, subsequently, an oestrous cycle was induced by intravaginal progesterone ...

The effects of oxytocin and pgf2α injections on semen quality and libido in buck [PDF]
The aim of the present study was to evaluate the effects of exogenous oxytocin and PGF2α on seminal quality and libido sexualis in bucks. To investigate the role of these hormones on male fertility, semen samples from 20 Norduz bucks (3-4 years of age ...

ABSTRACT Modern deaths have become reiterations. That is, despite exhibiting a seemingly high‐level of diversity in death's representations in everyday lives, death suffers from a particular onto‐epistemological poverty that prevents it from being imagined otherwise.

ABSTRACT The Finnish Ayrshire cattle belong to the Nordic Red breeds. The basis of selection in Nordic Red breeds shifted from traditional pedigree‐based breeding values to genomic breeding values between 2011 and 2014. Joint genetic evaluation and admixture among the Nordic Red breeds have led to the formation of a composite Nordic Red population ...

Evaluating Selection Strategies Based on Inbreeding Load via Simulation
ABSTRACT Inbreeding load is the fraction of the mutation load that is due to recessive action of mutations. This load is only expressed in individual's inbred offspring. As such, inbreeding load contributes to genetic heterogeneity among individuals and can thus be used as a criterion of selection.
