Armagh, North Irland BT666 ln.The trial was ordered and paid by APC, Europe S.A.The purpose of the trial was to establish the apparent mink digestibility of crude protein (CP), in theproduct, and analyse the content of its amino acids.Material and methodThe sample of AP301 PB was received on the 21 st of February 2004.AP301 PB is spray dried animal blood cells, 20-30% of porcine and 70-80% of bovine origin.The trial was conducted as a regression design, consisting of 5 groups of three animals each. Adult malemink of the colour type Scanbrown were used. The diets contained AP301 PB equaling from 0 to 53%,of the dietary total crude protein. (table 1).Table 1.

Dietallowance was 300 kcal metabolizable energy (ME) per day the first 6 days, and 250 kcal ME the last 5days.The trial was conducted from the 2 nd to the 13 th of February 2004.Diets and faeces were analysed by Dansk Pelsdyr Foder A/S, Analyselaboratoriet.1Hemoglobin powder for Mink.
