Digestibility trial with Mink (Mustela vison)Mixed Blood Meal, Brünen (F326)Report concerning the digestibility of blood meal produced and delivered by SNP Brünen GmbH& Co. KG. The trial was ordered and paid by SNP, Handels- und Beteiligungsgesellschaft mbH& Co. KG, Engterstrasse 101, D-49191 Belm-Icker, Germany.The purpose of the trial was to measure the apparently mink digestibility of crude protein (CP) inthe delivered mixed blood meal.Material and methodThe sample of blood meal was received November 2006 from SNP Brünen GmbH & Co. KG.According to the informed the blood meal consists of 20-30% porcine- and 70-80% bovineblood, which has been dried in a paddle dryer.The trial was conducted as regression design, consisting of 4 groups of three animals each.Adult male mink of the colour type Brown/Glow were used. Diet 1 to diet 4 contained increasingquantities of mixed blood meal. In diet 4 the crude protein from mixed blood meal made up 46%of the total dietary crude protein content (table 1).Table 1.

Data from theseanimals (one from diet 3 and one from diet 4) were eliminated from the analysis, due to inadequateintake of feed. There were no indications that the reduced intake of diet was caused bythe test ingredient.Consistency of faeces was optimal for all animals.DigestibilityThe apparent digestibility of crude protein in the mixed blood meal produced and delivered bySNP Brünen GmbH & Co. KG was measured to 82%, whereas the true digestibility was calculatedto 85%.*********Carsten Hejlesen09/01/07.Mixed Blood Meal for mink.
