Precision animal nutrition is about providing precise nutrient inputs to consistently assure animal health and productivity. It is set to play an important role in narrowing the productivity gap of livestock and fish. Trouw Nutrition and Skretting have respectively developed NutriOpt and AquaSim, modular precision-feeding systems made up of proven components that offer the latest nutritional science data and technology. When used together, these components make it possible to fine-tune a feeding strategy with high accuracy. Precision nutrition in an important part of producing more with less.
NutriOpt precisely calculates the most efficient approach. In doing so this precision-feeding system contributes to improvement of feed conversion, while at the same time advancing animal health and improving financial results. NutriOpt was introduced in 2013 and rolled out in 2015 to Benelux, Canada, Czech Republic, UK, Indonesia, Turkey, Spain, Brazil, China, Italy, Poland and Russia.
Split feeding is a good example of how NutriOpt can work. Egg production is a physiologically complex process for the hen, involving the mobilisation of different amounts and types of nutrients at different times of the day. Precise feeding is required in order to match the circadian biological rhythm of the animal. Trouw Nutrition conducted extensive research to determine the exact nature of the hen’s changing nutritional requirements across the egg formation cycle. By opting for a split feeding regime, it is possible to achieve improved eggshell quality and laying persistency on a reduced nutrients intake, when compared with a single-feed approach. The morning feed delivers the nutrition for energy, protein and phosphorous for egg-lay production, while the afternoon feed meets the requirements for eggshell formation. This not only offers a reduction in feed and production costs, but also results in more effective delivery of feed ingredients, with less excretion of nutrients. Moreover, it leads to improved shell quality and 30% less broken or shell-less eggs.
One of the main developments in AquaSim in 2015 was the Protec calculator, an easy-to-use tool that demonstrates the cost-benefits of using Protec (our fish health diet) in various situations. It gives the break-even situation for either better growth, lower mortality or higher fish quality. This tool is now being used in all major salmon producing countries.
The AquaSim calculator can for instance show the difference in production time between high energy feed (Premium) and normal growth feed (Optiline) for salmon. It thus gives customers the possibility to differentiate between fish groups in order to be able to deliver harvest size fish for a longer period. The difference can be shown either through shorter production time to harvest weight, or production of a bigger fish in the same production time. AquaSim can also give a cost-benefit analysis of the different products and productions
