Zootechnical and environmental effects of high energy feed in growing-finishing pig diets corresponding with CORPEN recommendations

Effects on animal husbandry and the environment were studied using high energy feeds. The diets corresponded or did not correspond with CORPEN recommendations (1996). A total of 288 growing-fattening pigs…

Effect of reduction of dietary protein level, associated with an adjusted electrolytic balance or not, on performance of lactating sows exposed to 23 or 26°C on average

The effect of dietary crude protein (CP) level, associated with a reduced electrolytic balance (EB) or not, was tested on 52 crossbred Large White x Landrace sows exposed to 23…

Comparison of 4 feeds given to piglets weaned at 28 days of age: do acid whey powder and extruded maize improve performance results

The inclusion of acid whey powder and extruded maize in weaning feeds was studied. A total of 347 piglets weaned at 28 days of age were used. The two feedstuffs…

Pigs keeping over a fattening period of 14 (standard) or 20 weeks (heavy): effect on meat quality and on cured-cooked hams processing

Two trials were carried out in two French experimental farms in order to quantify growth performances of group-housed barrows or gilts over two growing-fattening period durations corresponding to production of…

Pig keeping over a fattening period of 14 (standard) or 20 weeks (heavy): effect on growth performance

Two trials were carried out in the research stations of ITP (trial 1) and EDE (trial 2) to quantify growth performances of group housed barrows and gilts over two fattening…

Ammonia and nitrous oxide emissions for finishing pigs breeded on straw litter

The nitrogen loss in straw-based pig-on-litter systems is higher than in slatted-floor systems but the ammonia and nitrous oxide emissions are not well-known. Moreover, the effect of animal density on…

Experimental evaluation of two husbandry methods for growing-finishing pigs

The aim of this study was to evaluate the influence of an alternative husbandry method for growing-finishing pigs on animal welfare, growth performance, carcass and meat quality traits, and its…

Intra and inter raw material variations in phosphorus digestibility of several cereals and peas in growing pigs

A trial was undertaken, using growing pigs (45-49kg), in order to estimate the intra and inter feedstuff variability of the digestibility of total phosphorus (P) and phytate P in wheat,…

French pig production systems: a typology of pig owning farms

In 2002, a study on the 2000 agricultural census aimed to identify the main pig farming systems in France. This work characterised two levels of typology of pig production systems,…

New standardised criteria for GTE performances

The growth and food consumption curves modelled in this study correspond to current pig farm performance levels.The resulting standardised criteria make it possible to compare pig farms whatever their average…

Heavy pigs, meat quality and chemical composition of raw muscles and cured-cooked hams

Two trials were carried out in two French experimental farms in order to quantify growth performances of grouphoused barrows or gilts over two growing-fattening period durations corresponding to production of…

Growth performance of pigs slaughtered at 110 kg or above 140 kg

Two trials were carried out in the research stations of ITP (trial 1) and EDE (trail 2) to quantify growth performances of group housed barrows and gilts over two fattening…
