Benefits
Phase feeding will more closely match the pig’s nutrient requirements and minimise the over- and underfeeding of nutrients. The feed will be better utilised by the pigs, in favour of both production economy and reduced N-emissions.
Practical recommendation
• To get the maximum benefit from phase feeding, diets and feeding should be established based on actual animal performance and profitability/performance goals for each stage of production. It is easier to develop with a small number of pigs per batch (to manage heterogeneity)
• Diets should be formulated on a digestible amino acid basis rather than on a total amino acid or crude protein basis, crude protein should preferably be kept at a low level and ingredients should be analysed for their nutrient contents.
• A phase feeding system is complex and factors such as the availability of high-quality protein feed ingredients, the managing and ordering of feed as well as the need for additional feed bins on the farm must be considered.
• Consult with an advisor or nutritionist to adjust the feeding plan accordingly to meet the production goals
