ARTICLE FEED & ADDITIVE MAGAZINE March 2023 69 Berlin (Germany), to compare the effects of 4 treatments: One negative control, two commercial products based on phytogenics (P1 & P2), and a new technology (NUQO©NEX / NQ). The effects were measured on performance of the birds and apparent ileal digestibility of feed at 21 days of age. Researchers observed that the combined product not only improved digestibility of nutrients (crude fat, crude protein, and starch) but increased digestibility of minerals (crude ash, calcium, and phosphorus) as compared to the negative control. The other two solutions improved digestibility of some nutrients and minerals but to a lower extend than NQ. Performance results at 21 days are well in line with the observed effects on digestibility. The NQ treatment had the strongest effects on nutrient and mineral digestibility, and had the highest improvement in performance at 21 days, with better gain (+2,2%) and improved FCR (-0,6%) as compared to the control. All in all, the treatment NQ showed an improvement of feed digestibility that resulted in an improved performance, compared to classic products based on phytogenics. CONCRETE IMPACT ON FEED COSTS WITH A CONSERVATIVE? MATRIX VALUE Another trial was conducted on a research farm, in Cairo, Egypt during 35 days in summer 2022. The broilers were fed a 3-phases diet (Starter/Grower/Finisher). The negative control diet was formulated with a matrix value of 30kcal and 0,3% crude protein. All diets contained enzymes (Phytase and NSP) and toxin binders. Starter and grower diets included a coccidiostat but no growth promoters. The Inclusion levels of various feed additives were as prescribed by the respective manufacturers in all diets. A matrix value for the enzymes was also applied according to the manufacturer’s recommendations, meaning that the matrix value of NUQO© NEX was applied on-top of the enzyme matrix. In a nutshell, the 4 treatments were as follows: CO: Control (without antibiotics) /
