Experiment to study the effects of a partially or totally slatted floor during the growing/finishing period on growth performance and ammonia emissions

The aim of this study was to determine the effect of a partially slatted floor compared to a totally slatted floor on growth performance and ammonia emissions from a fattening…

Modelling heat production in group-housed growing pigs exposed to ambient temperatures ranging between 12 and 29°C

The effects of ambient temperature (T, 12 to 29°C), body weight (BW, 30 to 90 kg) and metabolisable energy (ME, kJ/j) intake on components of energy balance were studied in…

Influence of range of cycling temperature on the performance of growing pigs kept at an average ambient temperature of 20 or 28°C

Three trials, each involving 192 crossbred pigs, were carried out to evaluate the effects of ambient temperature of 20 and 28°C maintained constant or cycling over the day by 1.5,…

Effect of air movement and ambient temperature on the zootechnical performance and behaviour of growing-finishing pigs

Two experiments, each involving on 192 feeders, were conducted to determine the effect of air movement and ambient temperature on the pigs performance and behaviour. Treatments included three ambient temperatures…

Halothane sensitivity : a negative effect on sensory qualities

The halothane sensitivity gene affects the sensory qualities of loin and of cooked and cured hams. Heterozygous animals hold an intermediate position between the two homozygous animals for many quality…

Maîtrise des salmonelles en abattoir de porc

La maîtrise de la contamination des carcasses de porc par les salmonelles passe par l’identification, de l’élevage jusqu’à l’abattoir, des points critiques et par la détermination des mesures préventives associées.…

Les stations de traitement des effluents porcins. Estimation des coûts et conséquences économiques

L'objectif de la présente étude est de réaliser une évaluation économique des systèmes de traitement du lisier actuellement en conditions normales de fonctionnement. On s'attachera aux montants des investissements nécessaires…

Drenching in pig slaughterhouses : many advantage throughout the process

The showering of pigs in slaughterhouse during summer improves the pig welfare, the cleanless of pigs and the quality of anaesthesia. The working conditions of pigmen are also improved.

Verotoxic E: Coli E. Coli O157:H7, etc. No major risk in slaughtering cutting of pork

Verotoxic E. coli strains (VTEC) do not at present seem to represent a major hazard in the slaughtering-cutting of pork. In our study on 4469 samples (carcasses and cuts, faeces,…

Incidences des paramètres d’ambiance sur les performances zootechniques du porc charcutier

Effet sur les performances zootechniques du porc en engraissement, de paramètres d’ambiance essentiels : température ambiante (alimentation à volonté ou rationnée...), humidité relative, qualité de l’air (teneur en CO2, NH3,…

Anaesthesia of pigs with CO2 : grouping is best

The study consisted in an evaluation of the welfare of pigs before and during anaesthesia with CO2. The results in terms of heart rate suggested that stress was highest when…
