broiler, vitamin, requirements
In a time of record feed prices, nutritionists and production managers continue to look for opportunities to lower growout costs. Even though their contribution seldom exceeds 1-2% of feed costs, vitamins are not immune to this cost-crunching scrutiny. Furthermore, in late 2017, an unparalleled drop in global vitamin supply resulted in sharply increased prices, and in some cases, outright shortages. Such events have placed pressure on vitamin fortification levels in broiler feeds. Nutritionists decide on the fortification rates based on a variety of criteria – bird age, production phase, field experience, research trials, and so forth. The rapid change in broiler genetics is probably the biggest factor that affects long-term fortification levels.
