Should male pigs vaccinated against boar taint be restrictively fed after the second vaccination ?

Poster. An over-consumption of feed was noticed in male pigs vaccinated against boar taint (Improvac®) after the second vaccination (V2).The increase in feed intake may result in increased body fatness…

Modeling growing pig feed intake as a function of body weight, according to the expression of daily intake

Poster. Increasingly, modeling approaches are used as an alternative to animal testing. In pigs, growth can be simulated using the different available feed intake relationships to body weight and growth…

Utilisation of soybean meal in pig diets can be reduced through the formulation of low crude protein diets based on rapeseed meal and synthetic amino acids, including L‐Valine

Poster. One hundred and forty‐four (144) group‐housed growing‐finishing pigs were allocated to one of three experimental feeding strategies. Diets S were formulated with soybean meal and their dietary crude protein…

Effect of the dietary net energy content on the spontaneous feed intake of growing‐finishing pigs housed individually

The effect of dietary net energy (NE) content was investigated on 96 lean-type barrows, housed individually and fed ad libitum. Six NE levels (8.1, 8.7, 9.3, 9.9, 10.6 and 11.1…

Effect of long-term feeding and dry or liquid feeding on the use of rapeseed meal in pig diets

In Experiment 1, the effect of rapeseed meal incorporation (0 or 10%) in sow and/or pig diets was studied in two batches of growing pigs. No significant dietary effect was…

Consumer acceptability of dry‐cured hams from entire male pigs, gilts or barrows

Poster. The aim of this study was to assess the consumer acceptability of hams dry‐cured for more than seven months, processed from barrows, gilts or two groups of entire males…

Genomic selection: principles and possible uses in pig genetic improvement schemes

Genomic evaluation is a new methodology to estimate the breeding value of livestock. Its principle is to subdivide the genome into a very large number of chromosomal segments (CS) determined…

Genetic factors influencing major congenital anomalies in pigs

Although the incidence of congenital anomalies is quite low (around 1%), it is a significant problem in the pig industry. These defects have a serious impact on animal welfare and…

On-farm feed production gains in depth and diversity

In order to better understand the segment share and characteristics of feed produced on-farm in French pig farms, a survey was led on the full population of pig farms that…

Investigation of reproduction troubles in sows and gilts : How can we use hormonal profiles and echography to improve farm results ?

Influence of bowl drinker flow rate on water consumption and wastage by pigs from weaning to slaughter

Two experiments were carried out to determine the influence of bowl drinker flow rate on water consumption and wastage by growing-finishing pigs. The first trial involved two batches of 200…

Trends in household purchases of pork products in different retail channels

Household food consumption patterns are influenced by many factors, most notably by consumer expectations, perceptions and buying behaviours. Using data from the Kantar Worldpanel, different indicators related to the purchases…
