The administration of diets contaminated with low to intermediate doses of deoxynivalenol and supplemented with antioxidants and binding agents slightly affects the growth, antioxidant status and vaccine response in weanling pigs
Lo Verso, Luca; Dumont, Kristina; Lessard, Martin; Lauzon, Karoline; Provost, Chantale; Gagnon, Carl A.; Chorfi, Younès; Guay, Frédéric (Oxford University Press, 2021-08-18)This study aimed to evaluate the impact of grading levels of deoxynivalenol (DON) in the diet of weaned pigs, as well as the effects of a supplementation with antioxidants (AOX), hydrated sodium calcium aluminosilicates (HSCAS) and their combination ... -
Deoxynivalenol (DON) naturally contaminated feed impairs the immune response induced by porcine reproductive and respiratory syndrome virus (PRRSV) live attenuated vaccine
Savard, Christian; Gagnon, Carl A.; Chorfi, Younès (2015-07-31)Cereal commodities are frequently contaminated with mycotoxins produced by the secondary metabolism of fungal infection. Among these contaminants, deoxynivalenol (DON), also known as vomitoxin, is the most prevalent type B trichothecene mycotoxin ... -
Effect of deoxynivalenol (DON) mycotoxin on in vivo and in vitro porcine circovirus type 2 infections
Savard, Christian; Provost, Chantale; Alvarez, Fernando; Pinilla, Vicente; Music, Nedzad; Jacques, Mario; Gagnon, Carl A.; Chorfi, Younès (2015-04)Deoxynivalenol (DON) is a mycotoxin produced by Fusarium spp and is a common contaminant of grains in North America. Among farm animals, swine are the most susceptible to DON because it markedly reduces feed intake and decreases weight gain. Porcine ... -
FosteraTM PRRS modified live vaccine efficacy against a Canadian heterologous virulent field strain of porcine reproductive and respiratory syndrome virus (PRRSV)
Savard, Christian; Alvarez, Fernando; Provost, Chantale; Chorfi, Younès; D'Allaire, Sylvie; Benoit-Biancamano, Marie-Odile; Gagnon, Carl A. (2016-01-01)Vaccination is a useful option to control infection with porcine reproductive and respiratory syndrome virus (PRRSV), and several modified live-PRRSV vaccines have been developed. These vaccines have shown some efficacy in reducing the incidence and ... -
Impact of deoxynivalenol (DON) contaminated feed on intestinal integrity and immune response in swine
Lessard, Martin; Savard, Christian; Deschene, Karine; Lauzon, Karoline; Pinilla, Vicente; Gagnon, Carl A.; Lapointe, Jérôme; Guay, Frédéric; Chorfi, Younès (Elsevier, 2015-02-17)This study was performed to characterize the influence of consuming DON naturally contaminated feeds on pig's intestinal immune defenses, antibody response and cellular immunity. Sixteen 4-week-old piglets were randomly allocated to two dietary treatments: ... -
In vitro effect of deoxynivalenol (DON) mycotoxin on porcine reproductive and respiratory syndrome virus replication
Savard, Christian; Pinilla, Vicente; Provost, Chantale; Segura, Mariela; Gagnon, Carl A.; Chorfi, Younès (2014-03)Deoxynivalenol (DON) is a mycotoxin produced by Fusarium spp. Among monogastric farm animals, swine are the most susceptible to DON as it markedly reduces feed intake and decreases weight gain. DON has also been shown to increase susceptibility to ... -
In vivo effect of deoxynivalenol (DON) naturally contaminated feed on porcine reproductive and respiratory syndrome virus (PRRSV) infection
Savard, Christian; Pinilla, Vicente; Provost, Chantale; Gagnon, Carl A.; Chorfi, Younès (2014-12-05)Deoxynivalenol (DON), also known as vomitoxin, is the most prevalent type B trichothecene mycotoxin worldwide. Pigs show a great sensitivity to DON, and because of the high proportion of grains in their diets, they are frequently exposed to this ... -
Incognito, une toxine peut anéantir votre stratégie vaccinale contre le SRRP
Chorfi, Younès; Gagnon, Carl A.; Crost, Cécile; Poirier, H. (2016-06-01)Les céréales sont une excellente source nutritive tant pour les porcs que pour les micro-organismes. Certains d’entre eux, les champignons, peuvent s’y développer et produire diverses molécules dont des toxines dites mycotoxines (myco- préfixe ...
