Some natural feed additives have antimicrobial properties, including plant extracts such as oregano oil, which have been reported to have some protection against bacteria and protozoa. This is of particular interest as it can support the bird during challenges such as blackhead, where medicines to treat this infection are no longer licensed for use.
Betaine, extracted from sugar beet, is another important ingredient used in ForFarmers’ Traditional Turkey Range Diets. It can help the intestinal cells remain optimally hydrated and form a tight barrier against any pathogens attempting to cross the intestinal wall. “This barrier must be maintained securely as a primary line of defence, and therefore applying Betaine in the diets is essential to maintaining good bird gut health”, concludes Andrew.
Feed enzymes have virtually become a given inclusion into poultry diets to help increase feed efficiency and intestinal health. By aiding digestion of feed, faecal moisture is reduced. This has significant benefits as most, if not all, health challenges are more easily managed in flocks housed on drier bedding.
Some of the enzymes available will primarily target the anti-nutritional properties present in cereals, whilst others may specifically target the release of phosphorus, for example. Much of the phosphorus present in cereals, pulses and other plant derived ingredients is poorly available to the bird’s own digestive capabilities and is made available by adding enzymes which can release more of the phosphorus to the bird.
Feed enzymes concurrently bring efficiency and savings to the feed cost of rearing birds and also environmental benefits in terms of reduced potentially damaging environmental pollutants such as phosphorus.
In addition to using additives to help support health and efficiency, targeted core nutritional principles can be applied, for example, to optimise intramuscular fat for succulence.
