AB Vista introduces a reference guide on fibre analysis using NIR technology.

AB Vista has produced a new reference guide on fibre analysis. The guide provides poultry and swine producers with an introduction to the benefits of moving from conventional fibre methods to total dietary fibre analysis using NIR technology.

The reference guide contains the results of non-starch polysaccharide (NSP) analysis of feedstuff samples from around the world. AB Vista published this guide in conjunction with the launch of a new NSP analysis feature within its Feed Quality Service. The NSP analysis service gives nutritionists the ability to analyse the NSP content and its fractions (soluble and insoluble) within customers’ raw materials.

Shift

AB Vista’s Head of Global Technical, Gilson Gomes says the company anticipates that the level of interest in the fibre fraction of the diet is likely to increase. “This is due to a variety of different factors, such as the fact that nutritionists are looking to replace soybean meal and the interest for more local ingredients increases. Also there is a desire to improve gut function through the use of more fibrous ingredients”.

Gomes believes that an improved knowledge of fibre composition is needed in order to effectively employ nutritional strategies which can serve to boost fibre fermentation by the gut microbiota, thereby positively influencing the host metabolism and overall performance. “Our new NIR analysis service will enable us to analyse the level of NSP and suggest feed strategies for customers to get more from their fibre fraction”, states Gomes. “NIR is a well-established method for analysis and quality control of ingredients providing fast and inexpensive analysis. Results of NSP calibrations for feedstuff have shown that it is possible to predict NSPs for a range of feedstuffs.”

Variation

AB Vista will continue to develop its service offering, with results of lignin being incorporated soon to provide total dietary fibre (NSP + lignin) analysis. The guide illustrates NSP variation in barley, canola meal, corn, soybean meal, sorghum, and wheat. Producers and nutritionists can request a free copy of the guide from their regional AB Vista representative.
