Group housing of sows : acquired and future research

The revised European directive (91/630) implements group housing for gilts and sows. Reports planned in 2004 and 2008 will draw up a review of studies carried out on further development…

Is it necessary to give fibrous diets to group-housed sows ?

The effects of a fibrous diet ( F : 32% neutral detergent fibre, NDF) and a control diet ( T : 20% NDF) on the well-being of pregnant sows housed…

Ambient temperature influences the choice made by pigs for certain types of floor

Enriching the environment of pigs is a way in which to improve welfare and it is used when legislation is formulated. An ethological study was carried out to determine the…

Influence of tooth resection on behaviour, performance and physiology of piglets

Tooth resection performed in order to avoid injuries to piglets and to the sow’s udder is now criticised. In order to assess short term consequences, two experiments were performed. The…

Ammonia emission during pig slurry storage : laboratory and pit results

Few studies have been already achieved on ammonia volatilisation during slurry storage. The originality of this work is the comparison of data obtained in laboratory conditions with data measured on…

A study of sources of variation for the “structureless meat” default in fresh hams

In the context of the 23rd national test for the evaluation of terminal products, 1151 pigs from eight genetic types were scored for the presence of the “structureless meat” default…

Factors involved in introducting sows

There is a consensus on the importance of introducing sows for maintaining healthy livestock. Introducing sows requires defining the health status of the sows and expectancies.The health status of the…

Detailed chemical composition of pig feed and manure.

The analysis of the composition of pig manure for 22 elements enabled us to quantify its fertilising potential and toxicity hazards for the quantities usually spread. On the basis of…

An experimental truck to study pig welfare during transport

The carefully designed fitting-out of this experimental truck and the results of tests will make it possible to improve the equipment of trucks for conventional transport.We emphasise the usefulness and…

Tail docking and teeth cutting in piglets. Behavioural, zootechnical and health consequences

artial cutting of teeth in piglets (to prevent wounding of piglets and the udders of sows) and tail docking (to prevent tail biting) have lately been challenged. A behavioural, zootechnical…

Facteurs de croissance et produits alternatifs en alimentation porcine : réglementation, modes d'action et conséquences technico-économiques

Les antibiotiques sont non seulement utilisés en élevage dans un but thérapeutique mais également incorporés à faible dose dans l'aliment avec un but strictement zootechnique d'amélioration des performances. Les mécanismes…

Salmonella contamination of butchery pig transport vehicles and holding pens at slaughterhouses

All butchery pig transport vehicles and nearly half the alleys of holding pens at slaughterhouses are contaminated with Salmonella after use. They are therefore potential sources of Salmonella contamination for…
