Viabilitas Spermatozoa Babi Dalam Pengencer BTS (Beltsville Thawing Solution) Yang Dimodifikasi Pada Penyimpanan Berbeda [PDF]

open access: yes, 2008
The optimal storage temperature for preserve boar semen is 17-18°C. The temperature fluctuations can decrease sperm viability. The aim of this study was to obtain a boar semen extender for Artificial Insemination (AI) at a certain distance area.

Impact of Sorting and Catch Media on Porcine Sperm Motility, Capacitation, and Viability

open access: yesAndrology, EarlyView.
ABSTRACT Background Fluorescence‐activated cell sorting (FACS) has emerged as a powerful tool for selecting spermatozoa of a desired population of fluorescent biomarkers, offering potential applications in reproductive biology and agriculture. However, concerns remain regarding sorting‐induced physiological alterations that could compromise spermatozoa

Hyperactivation and Tyrosine Phosphorylation of Cryopreserved Stallion Spermatozoa in Relation to Conventional In Vitro Fertilization Blastocyst Production

open access: yesAndrology, EarlyView.
ABSTRACT Background Challenges in establishing clinical conventional in vitro fertilization (IVF) in horses include variation in sperm and oocyte quality, which can be affected by mare age. Extended preincubation of stallion spermatozoa has resulted in successful IVF.

Fat area and lipid droplet morphology of porcine oocytes during in vitro maturation with trans-10, cis-12 conjugated linoleic acid and forskolin [PDF]

open access: yes, 2012
Lipid droplets (LD) in porcine oocytes form a dark mass reaching almost all cytoplasm. Herein we investigated changes in fat areas, cytoplasmic tone and LD morphology during in vitro maturation (IVM) of porcine oocytes cultured with 100mM trans-10, cis ...

Morphometric and Paleobiological Insights Into Pleistocene Sicilian Wolf Populations

open access: yesActa Zoologica, EarlyView.
ABSTRACT The Pleistocene wolves (Canis lupus) from Sicily represent one of the few known insular populations of this species from that time period. Despite their potential relevance for understanding carnivore adaptations in insular contexts, no dedicated study has previously investigated their morphology and evolutionary significance.

Environmentally adjusted productivity growth and shadow prices for dairy farms

open access: yesCanadian Journal of Agricultural Economics/Revue canadienne d'agroeconomie, EarlyView.
Abstract We estimate the environmentally adjusted productivity growth and shadow price for Ontario dairy farms. We use an input‐oriented directional distance function and farm‐level data from 2000 to 2020. First, we find that while GHG emissions per cow increase with higher milk yields, emission intensity decreases as milk yield per cow increases.
