Nitrogen (N) rejections are a problem of importance in cattle production. In pasture, the amounts of N rejected by the cattle are large since grass N content exceeds the ‘animals’ requirements. The present study aims to quantify, with dairy cows in a rotational system, N rejections from urine. The trial paddocks were fertilized with compost, slurry or mineral N and grazed during 7 days by 35 dairy cows in late lactation. Milk urea concentration was determined in tank milk samples every day. Urine samples were taken from each cow at the 3rd and the 5th day after the entry in the grazing plot. Urine N and creatinin were determined to quantify urine N excretion. These observed values were compared to urine N excretion data obtained from dry matter intake and grass N content. The mean observed urine N excretion of 312 g N day-1 was similar to the mean calculated urine N excretion of 330 g N day-1. The correlation between calculated urinary N excretion and observed urinary N excretion was significant (P<0.001; r2= 22.4%) and the correlation between observed urinary N excretion and milk urea content tended to be significant (P<0.10; r2 =60%). From these data, it appears that urine N excretion prediction can be more precise with tank milk urea than with urine N excretion calculated from N intake. This research has to be continued and to be repeated during other grazing periods and with cows at different lactation periods to validate the results. [less ▲]

A code of good practices was established by each European member state according to the nitrate directive. In Belgium, the nitrogen (N) inputs from slurry or compost are limited to 230 kg N/ha in pastures. Larger amounts can be applied when a program of additional measurements, including soil nitrates analysis, is followed by the farmer. This trial aims to measure nitrogen balance and soil nitrates in pastures fertilised with mineral nitrogen fertiliser (min N), pig slurry (S) or cattle compost (C). The pastures were grazed by dairy cows and the fertilisation allowed similar efficient N levels. N inputs by fertilisation were different at 169, 170 and 102 kg N/ha in C, S and min N plots respectively. The use of pig slurry and cattle compost as compared with mineral N fertiliser increased N balance and reduced apparent N efficiency. The nitrogen, potassium and phosphorus nutrition indexes, the number of grazing days and the milk yields per ha were not different. The soil nitrate contents were not increased by use of slurry or compost. The overall low nitrate contents suggested a low nitrate leaching with the three types of fertilisation. [less ▲]

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 ▲]
