Abstract

The purpose of this experiment was to study the regularity of growth performance, nutrient digestibility, and serum biochemical parameters with different dietary protein levels in growing female minks (Mustela vison). Sixty aged (50?3) days female minks were randomly divided into six groups according to a single-factor design. Each group included ten replications in which one mink fed in a single cage. The minks were fed experimental diets with protein levels of 28%, 30%, 32%, 34%, 36% and 38%, respectively. The metabolism trial was used to analyze the digestibility of protein and fat, nitrogen deposition, protein biological value, feed conversion ratio, and body weight gain of minks at 65, 80, 95 and 110 days of age. The results showed as follows: at 50 to 65 days of age, body weight gain and feed conversion ratio of minks fed diet with 38% protein were significantly higher than those of minks fed diets with 28% and 32% protein (P<0.01). At 50 to 110 days of age, body weight gain of minks fed diets with 32% and 34% protein was significantly higher than that of minks fed diet with 28% protein (P<0.05). Compared with the 28% and 30% protein groups, the minks in 32%, 34% and 38% protein groups had greatly significant digestibility of crude protein (P<0.01) at 95 days of age. The protein biological value and net protein utilization in 34% protein group were the lowest among all the groups (P<0.01) at 110 days of age. At 110 days of age, the serum urea nitrogen content in 38% protein group was significantly higher than that in the other groups (P<0.01), and the total amino acid content in 34% and 36% protein groups was significantly higher than that in 28% protein group (P<0.05). Considering the determination of indexes, it is recommended that dietary protein levels are 36% to 38% for minks aged 50 to 65 days; dietary protein levels are 34% to 36% for minks aged 66 to 80 days; dietary protein levels are 32% to 34% for minks aged 81 to 110 days.
