Prospects of commodity feed markets: Prospective analysis of price differences of pig feed in the EU, USA and Brazil

Pig feed formulations depend on the local availability of raw materials. The comparison of grain and meal prices revealed a comparative advantage against the EU of $ 48 / t…

Growth trends in Northern European pig production: the appearance of a new cross-border model

Germany, the Netherlands and Denmark are quickly becoming a single production area with geographical specialization of activities and significant cross-border exchanges of animals. The location of Germany facilitates trade. Its…

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

Poster. 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…

A simplified method of measuring greenhouse gas and ammonia emissions in pig grower-finisher barns

Levels of GHG and ammonia emissions can be determined by continuously measuring concentrations in barn rooms during the entire fattening period. However, the high investment of time and money required…

Effect of growth rate on longevity of boars in artificial insemination studs

Poster. Excessive growth rate has been identified as detrimental and a potential cause of premature culling of boars used in artificial insemination studs (AIC). And yet, there are few references…

Chain-based objects used as enrichment toys: effects on behavior and lesions in fattening pigs

Poster. Two batches of 120 pigs (10 pigs/pen) were used to investigate the effect of four different objects on the behavior and body condition during the fattening period. In previous…

Does group housing increase the risk of reproduction problems in French sow herds?

The aim of this study was to investigate reproductive performance and possible reproductive problems (late estrus, infertility, reasons for culling) in herds with either group‐housed or individually housed pregnant sows.…

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…
