Risk and protective factors for ASF in domestic pigs and wild boar in the EU, and mitigation measures for managing the disease in wild boar

EFSA Journal, Volume 22, Issue 12, December 2024.
Abstract Five epidemiological aspects of ASF were evaluated using literature reviews, field studies, questionnaires and mathematical models. First, a literature review and a case–control study in commercial pig farms emphasised the importance of biosecurity and farming practices, including the spread of manure around farms and the use of bedding ...

Management of intraspecific aggression in two bull giraffes (Giraffa camelopardalis ssp. rothschildi)

Zoo Biology, Volume 43, Issue 4, Page 383-390, July/August 2024.
The gonadotrophin‐releasing hormone vaccine Improvac® was associated with a reduction in aggressive behaviors, although these did not significantly diminish until the fourth vaccination. However, 8 months following the initial vaccination with Improvac®, the unvaccinated bull exhibited heightened aggression, resulting in an injury to the vaccinated ...

Developing fertility control for rodents: a framework for researchers and practitioners

Integrative Zoology, Volume 19, Issue 1, Page 87-107, January 2024.
A framework to guide researchers developing wildlife fertility control applications requires iterative and parallel studies from the laboratory and enclosure studies through to population‐level, replicated field trials. Modeling different scenarios may guide field testing of fertility control either applied alone or combined with other management ...

GnRH-Based Immunocastration Vaccines: Comparative Analysis and Role in Boar Taint Reduction

Vaccines
Boar taint is a persistent challenge in pork production, caused primarily by the accumulation of androstenone and skatole in adipose tissue. It affects 5–40% of uncastrated male pigs and is perceived negatively by a substantial proportion of consumers ...

Effects of immunization against GnRH on gonadotropins, the GH-IGF-I-axis and metabolic parameters in barrows

Animal, 2008
Surgically castrated male piglets (barrows) reveal an increase in LH and a decrease in GH compared to untreated boars. Boars that were castrated by immunization against gonadotropin releasing hormone (GnRH) have decreased LH but maintain GH.
