.01Nys Y. / Mineral nutrition of pig and chicken
Challenge for animal production
2050: world population expected to rise by 33%, +2.3 billions,Food demand increases with higher inhabitant‘s incomeAsia-Africa: 80% population but only 36%corn, 13% soybean, 50% wheat
We must increase food security globally
particular demand from the consumers:
nutritional value, hygienic and sensorial quality,
Need to take into account welfare in production system
Sustainability of production, environmental concernCompetition for landShortage of feedstuffs (about 20 years for inorganic Zn)Eutrophication, plant phytotoxicityCompetition with other food industry and low economical margin
Produc on of high quality products for human nutri on taking into account sustainability of production systems and environment.

Challenge for innovative feeding systems in monogastrics
What is the impact on mineral nutrition in monogastric animals?
Meat, eggs
Product quality

excretion
Welfare issue
Save resources
Feeding Systems
RequirementsMineral implicated in numerous functions in animals (organ, tissue, celllevels) :growth, bone formation, enzymatic activities …• Variable response to nutrient depending on animal parameters
(performance or tissue composition)
Requirements established on performanceneeds for other functions ??
Adjusting mineral supply to requirement• Mineral contents in feedstuffs and mineral sources• Interactions between dietary components
Improve bioavailability of mineral
Macro-elements: P, Ca (g/kg)Trace-elements: Fe, Cu, Zn, I, Se (mg/kg)

Changes in phosphorus cost
ENVIRONMENT
•Phosphorus excre on in poultry manure pollu on : eutrophication of ground water
• non-renewable resource
Phosphorus, a key element
Involved in many metabolic functions: nucleotids, nucleic acids,phospholipids (cellular membranes), bone mineralisation (hydroxyapatite),regulation of acid-base balance
Specific requirement in phosphorus for growth , egg formation and bone mineralisation
Constituent of nucleotides nucleic acids: DNA - RNA

Bioavailability of Zn sourcesBioavailability
– Part absorbed and used for normal metabolic functions in healthy bird (can include Zn storage, bone , liver for some authors)
– Depends on sources, diets, physiological parameters (intestinal solubility), experimental test.
Reduction of Zn availability by phytic acid, reinforced by Ca.– High correlation between phytate and Zn in feedstuffs– phytase decrease this negative interaction (10mg)
Antagonism between trace elements when chicks fed on marginal dietary levels Cu-Zn.
Measure of bioavailability – Comparison the slopes of response (growth, Zn deposition) to different levels of
a source of dietary Zn relative to a reference source

FEEDING STRATEGY• Animal Requirements change with criteria: need to take into account various parameters to optimise performance
need to take into account complexity due to variability of response and interac on, no single dose response
Availability of new tools to integrate complexity (model for dietary formula on) • Feed recommendation in sustainable system should integrate three objectives: production performance, environment and welfare
Product Quality • Limited influence on lipid fraction • Effects on oxidation remains controversial
an oxidant vs pro-oxidant interac ons between level and dura on of trace elements dietary level, ssue,
slaughtering conditions, product packaging and transformation, cooking. • Good potential of product enrichment in trace mineral but limitation due to Regulation in animal and human feeding and due to toxicity level for animals
Conclusions
