The managements were an intensive system with a high N fertilizer application at 136 kg N ha-1 and a stocking rate of 3.35 cows ha-1 (H-N), a system with moderate N application with 91 kg N ha-1 year-1 and the same stocking rate (M-N) and a system without N fertilizer application and with 2.51 cows ha-1 (0-N). The individual milk production was not affected by treatments but the milk yield per hectare was largely influenced by the stocking rate. Milk and plasma urea concentrations were the highest in the H-N group and the lowest in the 0-N group. Similarly, the system N balance was the highest in H-N and the smallest in 0-N group. Inversely the N use efficiency was the highest in 0-N group. Soil nitrate concentration in 0-90 cm deep cores was higher in H-N than 0-N samples.

This paper aims to contribute to the clarification of the effects of a diet rich in sugar beet pulp on animal behavior, growth performance, carcass quality and gut health of fattening pigs. Method. Two successive batches of 24 fattening pigs were each divided into two groups fed ad libitum either a standard diet based on cereals (STD, 19% NSP [non-starch-polysaccharides]) or a fibrous diet based on 23% sugar beet pulp (HFD, 31% NSP). Results. Pigs activity rate and feeder occupancy duration were increased by 57% and 165% for group fed HFD, respectively (P < 0.05). The fecal bacteria counts showed increases with HFD for Lactobacillus (10.21 vs 9.84 log10 of cfu.g-1 of feces dry matter, P < 0.05) and Bifidobacterium (9.49 vs 8.88, P < 0.01) but decreases for Enterobacteriaceae (4.85 vs 5.97, P < 0.001). Reductions of the average daily gain (788 vs 876 g per day, P < 0.001) and the dressing percentage (75.7 vs ...

For decades, investigations were carried out in determine the influencing factors and to point out opportunities of mitigation. In Europe, current NH3 emissions associated to pig production are about 24% lower than in 1990. However, further reduction seems necessary to avoid noxious effects on ecosystems. The main factors influencing NH3 production
