Cryopreservation of boar semen

, 2000
The world’s pig population is consistently being upgraded through the international trade of superior genetics. The two major systems that are used for this purpose are the transport of live animals and the export of frozen boar semen. The main limiting factors for a wider use of frozen-thawed (FT) boar semen are low fertility levels of FT in ...

Utilização de extrato de própolis verde no resfriamento de sêmen equino [PDF]

, 2014
Seminal cooling aims to prolong spermatic lifespan and fertilizing capacity due to reduction in energy metabolism of spermatozoa, providing enough period for transportation from the stallion to the mare.

Cryopreservation of boar semen

, 2008
Generally, spermatozoa from most boars survive poorly the customary process of cryopreservation. Post-thaw (PT) survivors often show unstable membranes, short life-span, and low fertilising capacity when artificial insemination(AI) is used. This thesis aimed at improving this situation by (i) freezing high sperm numbers in novel packages (MiniFlatPacks™

In Vitro Motility, Velocity and Capacitation Status of Merino Ram Spermatozoa [PDF]

, 2012
The objective of the present study was to determine the effects of Merino rams on the in vitro motility, velocity and capacitation status of ram spermatozoa. Four rams of proven fertility were used in this study.

Studies on the sperm reservoir of the pig oviduct [PDF]

, 2003
During sperm transport in the female pig a proportion of spermatozoa are arrested, often for 24 h or more, in a particular segment of the utero-tubal junction (UTJ) and the adjacent tubal isthmus, where a sperm reservoir (SR) is built up.

Growth performance and sperm quality of stress negative Piétrain boars and their hybrids with Duroc [PDF]

, 2013
peer reviewedThis study was conducted to evaluate the effects of genetic background and season on growth performance and semen quality of boars. Five genetic groups were evaluated, including stress-negative Piétrain boars with CC (PiCC) or CT (PiCT ...

COOLING CURVES OF THE BOAR SEMEN DILUTED IN ACP®103 EXTENDER ADDED OF POWDERED EGG YOLK IN FIXED CONCENTRATION

Ciência Animal Brasileira, 2016
The conservation of boar semen at lower temperatures might contribute to the further expansion of artificial insemination in this species. Egg yolk cryoprotectant properties have already been extensively tested on sperm cryopreservation of several ...
