Milk urea concentration is routinely determined in commercial dairy farms along with the official milk analyses carried out on milk samples for the dairies by the “Comité du lait”. The milk urea content do not modify milk price but can be useful for the farmers for diet calculation, milk urea content being related to the energy-protein ratio in the diet. The aim of this paper was to study the evolution of the milk urea content according to the months and the areas. Milk urea concentration changed according to the months owing to the diet: the summer diets, mainly composed by grass in many farms, were characterized by higher nitrogen content which as result an increase in milk urea concentration. The geographic areas can also influence milk urea concentration due to dietary difference. For example, in the Hesbaye area, beet and cereals are produced while in the Ardennes, grasslands are dominant. The urea content in milk can be an useful measurement for the diet calculations in order to decrease nitrogen waste and to reduce the feed costs. [less ▲]

From 1994 to 2004, Hill's Pet Nutrition received 4495 canine (65%) and feline (35%) uroliths from Benelux veterinary practitioners. They were sent to the Minnesota Urolith Center, USA for analysis. In 1994, 110 uroliths were analysed - 85% from dogs - and in 2003, 1067 uroliths were analysed - 59% from dogs. During this period, substantial changes were observed in composition. In 1994, 77% of the cats had uroliths composed of struvite, and 12% had uroliths composed of calcium oxalate. In 2003, feline uroliths were composed of 32% struvite, and 61% calcium oxalate. The same evolution was observed in the dogs. In 1994, 51% of canine uroliths were composed of struvite, and 33% of calcium oxalate. In 2003, 40% had struvite uroliths, and 46% had calcium oxalate uroliths. A significant effect of the size, the breed, and the gender were noticed in the dogs. The mean age of uroliths appearance was 7.3 years in the dogs and 7.2 years in the cats. The findings are similar to those previously published in the USA. [less ▲]

Le Sélénium (Se) est un oligo-élément indispensable au bon fonctionnement de l'organisme, notamment chez le bovin. Différents éléments plaident pour l’existence de déficits en Se dans le cheptel bovin et particulièrement dans les troupeaux allaitants. Solutions injectables, bolus, supplémentation des rations… différentes méthodes permettent d’assurer un statut en Se correct chez l’animal. Une autre alternative consiste à enrichir les aliments produits au niveau de l’exploitation en utilisant des engrais enrichis en Se. Le Service de Nutrition de la Faculté de Médecine Vétérinaire a testé l’effet de ce type d’engrais sur la teneur en Se dans les aliments produits et sur le statut Se d’un troupeau de vaches allaitantes [less ▲]
