Liquid feeding - The way forward

THE latest research and new technology for liquid feeding means it has taken a major leap forward offering a potential saving of as much as 5p per kilo deadweight. A three-year project, funded by the Meat and Livestock Commission and Defra, is under way at the MLC’s Stotfold Pig Development Unit and early results are very positive. Now a booklet has been produced by the MLC in conjunction with the British Pig Executive and Defra pointing out the factors that have to be taken into consideration and offering tips on how to avoid some of the pitfalls. MLC Pig Technical Manager Dr Pinder Gill said: "Many existing units were designed for dry feeding and for some the cost of conversion to wet feeding could be high. However, when building a new unit the capital costs are comparable. "Liquid feeding has the potential to bring about a substantial reduction in production costs. The trials at Stotfold have shown the savings can be as much as 5p per kilo deadweight." Dr Gill said the most important points were to: Explore all potential suppliers with a proven track record in the manufacture, supply and installation of liquid feeding systems. Take independent advice: commercial nutritionists with an established customer base using liquid feeds are a good source of information. Visit units with liquid feeding installations, where possible, to find out as much as possible on the advantages, disadvantages and experiences of other producers. Ensure that the supplier can provide technical backup support, especially in the event of systems failure. Consider the lifetime performance of the system. Make sure that replacement parts will be readily available. Consider the likely range of products you may use as the viscosity of materials will impact on choice of pumps, (eg positive displacement or centrifugal). Consider the level of complexity and staff training for systems operation. Make sure hygiene is considered at every stage.
