POULTRY DIETS OF THE FUTURE


The table below illustrates some of the key trends discussed, in a typical broiler formulation. Back in the 1980’s it was common to use both fishmeal and meat and bonemeal to limit levels of extracted soya in poultry diets. Full


fat soya was also often used to spread the number of raw materials, but the inclusion of amino acids would have been limited to lysine and methionine. Following the removal of meat and bone, as a result of the

BSE crisis in the1990’s and the drive towards vegetarian diets, broiler feeds today would typically have more soya in them, but this is now controlled by the use of alternatives, most commonly rapeseed, as well as peas or beans and higher levels of amino acids.

levels will decrease as the agronomic challenges of growing rape result in a declining acreage being grown. The key change will however be the increased use of a greater


range of amino acids which will drive down overall dietary protein, but also the reliance on soya. This should improve efficiency of production helping gut health and litter conditions in the broiler sector.


requirements to the animal, with less waste,” he says. “Importantly, while we currently use lysine, methionine,


threonine, tryptophan and more recently, valine in diets, the potential for isoleucine, arginine and other amino acids is looking very promising.” Today, Premier Atlas details the levels of 17 digestible AAs, for


both pigs and poultry, in over 200 feed ingredients, so that as future market requirements become clearer, the industry has the information required to meet them. “As supply increases and prices fall this will enable us to meet


growing requirements for more sustainable diets which are lower in protein and soya.” In addition to crystalline AAs, there has been a lot of interest in


alternative proteins, in particular insect protein, which could provide a useful nutrient contribution in the short to medium term. “There are still some legislative hurdles to overcome, but it


remains to be seen whether such products can be cost-effective in animal feeds. And with the shift in consumer sentiment about the responsible use of resources, we may also see more focus on using by-products from the food industry, and also from bioethanol and biodiesel production,” he says. Furthermore, Steve suggests there may be further developments


in enzyme technology in the future - particularly around the treatment of raw materials. “With all this progression, keeping up to date on accurate nutrient


values of raw materials will be ever-more important in making sure diets remain balanced,” he explains. For poultry specifically, and to a certain extent pigs, feed is by far


the biggest expense, equating to 70% cost of production. As the UK hurtles towards a potential ‘free-market’ situation globally, keeping a competitive edge will be vital. “The UK poultry industry must make sure it remains competitive


by feeding accurately and economically, while maintaining the outstanding quality we’re renowned for,” says Steve. “This means using the resources available to us in the best


way we can to maintain efficient production, and therefore, the interpretation and application of Premier Atlas data will be key.”


Future commitment Ultimately, in the future animal production will need to respond to the demands of the consumer, but twenty years on from the first edition of Atlas, Premier Nutrition remains committed to helping its customers achieve this. “The future is looking increasingly complex and indeed some consumer demands conflict,” Mick explains. “In the last two decades the industry has lost a number of raw


materials through legislative changes. At the same time there has been a huge drive for improved efficiency and greater sustainability. “Throughout this time, I’ve continued to use Atlas every single


day,” he adds. “And, I look forward to supporting our UK and international customers, to provide the expertise required to turn raw data into finished feed specifications.” Premier Atlas is available in published format and as an interactive
