Abstract
in English, French

This study determined whether mineral concentrations in the hooves of cattle with toe tip necrosis syndrome (cases) differed from those of cattle dying of all other causes (controls). Samples were collected over a 2-year period from 16 different feedlots and analyzed for 8 minerals [cobalt (Co), copper (Cu), iron (Fe), magnesium (Mg), manganese (Mn), molybdenum (Mo), selenium (Se), and zinc (Zn)]. Mineral concentrations in the hoof wall and solar horn of the same hoof were poorly correlated; Se was the most correlated (ρ = 0.865; P < 0.001), while Mg (ρ = 0.465; P < 0.001) and Zn (ρ = 0.157; P = 0.053) were the least correlated. The cases had significantly lower Mg concentrations in both the hoof wall and solar horn tissue compared to the control subjects. For every 10 ppm decrease in Mg, the odds of a diagnosis of toe tip necrosis syndrome (TTNS) increased by 1.13 times for the hoof wall (P = 0.002) and 1.21 times for solar horn (P < 0.001).

Étude cas-témoin des concentrations de minéraux dans les tissus de la corne des sabots provenant de bovins en parc d’engraissement atteints du syndrome de nécrose du bout de l’onglon (nécrose de l’onglon). Cette étude a déterminé si les concentrations de minéraux dans les sabots des bovins atteints du syndrome de la nécrose du bout de l’onglon (cas) différaient de celles des bovins qui mouraient de toutes les autres causes (témoins). Des échantillons ont été prélevés pendant une période de 2 ans dans 16 parcs d’engraissement différents et analysés pour déceler la présence de 8 minéraux (cobalt [Co], cuivre [Cu], fer [Fe], magnésium [Mg], manganèse [Mn], molybdène [Mo], sélénium [Se] et zinc [Zn]). Il y avait une faible corrélation entre les concentrations des minéraux dans la paroi du sabot et la corne du même sabot. Le Se était le minéral avec la plus grande corrélation (ρ = 0,865; P < 0,001), tandis que le Mg (ρ = 0,465; P < 0,001) et le Zn (ρ = 0,157; P = 0,053) avaient la plus faible corrélation. Les cas présentaient des concentrations de Mg significativement inférieures dans la paroi du sabot et les tissus de la corne comparativement aux sujets témoins. Pour chaque diminution de 10 ppm en Mg, la probabilité d’un diagnostic du syndrome de nécrose du bout de l’onglon augmentait de 1,13 fois pour la paroi du sabot (P = 0,002) et de 1,21 fois pour la corne (P < 0,001).(Traduit par Isabelle Vallières).
