Consequences on corporal composition variables of pig carcasses for introducing new weighing and grading methods in France in 1997

The new EU definition of lean meat proportion (called TVM : Teneur en Viande Maigre) has been introduced in France in 1997. Grading methods and carcass dressing have changed, leading…

Dietary fatty acid and carcass lean content. What effect on the quality of backfat ?

Supplying polyunsaturated fatty acids in pig diet affects fatty acid composition and technological properties (consistency, oxidability) of adipose tissues. The aim of this study is to evaluate the consequences of…

The effect of lysine/energy ratio on the performance of weaned piglets. Influence of using the post weaning diet up to 40 kg

Three hundred and sixty weaned piglets, with an average body weight of 7.2 kg, were allocated to treatments to determine the optimum ratio of digestible lysine/net energy (digest lys/NE). Four…

A comparison of wet or dry single-space feeders : their effects on growing pig performance, influence of meal or pelleted feed

Four different feeding-systems were compared in three trials :NR-G : dry feeder and pellets — NR-F : dry feeder and meal — NS-G : wet feeder and pellets — NS-F…

Comparison of a simple cereal based diet with two complex isoenergetic diets, through the association of fibre and fat

Three isoenergetic diets differing by their crude fibre content (36, 47 and 58 g/kg) and their fat content (27, 51 and 75 g/kg) were fed to 330 sows which weaned…

Modelling and optimising the Swiss pig breeding scheme. A comparison of the interest of central testing stations in Switzerland and France

In Switzerland the central testing station is currently used to test slaughtered full sibs (2 females and 2 castrates) of onfarm tested boars and sows. The equipment and sanitary status…

Residual food consumption in growing pigs fed ad libitum : method of calculation and genetic variability

Residual food consumption (RFC) in growing pigs represents the deviation of the actual daily food consumption of an animal from its consumption as predicted on the basis of its growth…

Influence of ventilation system and air flow rate on ammonia levels in pig fattening units
