Abstract: 
Seventy male Sprague-Dawley rats with an average live mass of 42 +/- 4 g were divided into 7 groups of 10 animals each. Group 1 received a control diet (32.2 mg Zn/kg DM), group 2 a zinc deficient diet (3.4 mg Zn/kg DM) ad libitum. The animals of group 3 were pair fed to group 2 with a diet sufficient in zinc supply (84.9 mg Zn/kg DM). Diets of groups 4 and 6 contained 2% or 5% of Masson pine pollen (zinc content 40 mg/kg DM of pollen) and giving zinc contents in the diets of 4.4 and 5.6 mg/kg DM. Diets of groups 5 and 7 were formulated to have the same zinc content as groups 4 and 6 by addition of zinc sulfate (group 5 and 7:4.4 and 5.5 mg Zn/kg DM). The groups 4 to 7 were also pair fed to group 2. After 26 experimental days the influence of pollen in state of deficient zinc supply on performance, zinc status, hematological parameters and lipid concentrations in serum and lipoproteins were determined. Zinc deficient animals (group 2) showed significant differences in all parameters investigated in comparison to the ad libitum control group 1 with adequate zinc supply. Significant differences on performance and zinc content, zinc binding capacity and alkaline phosphatase in serum between the groups 2 to 7 with the same level of feed intake depended only on the different zinc supply of the diet. Supplementation with pollen had no significant influence on these parameters compared to the corresponding groups with the same zinc content in form of zinc sulfate. The hematological parameters were influenced by the level of food intake but not by the zinc content or addition of pollen. The concentrations of cholesterol, triglycerides and phospholipids in serum and lipoproteins were significantly higher in the group 1 than in groups 2 to 7. Different zinc supply or addition of pollen in the groups 2 to 7 with same level of feed intake had no influence on lipid concentrations in serum.
