Blood chemistry, thyroid hormones, and insulin serum content in bulls fed a ration limited in energy

The aim of this study was to determine blood biochemical profile and selected hormone concentrations in bulls fed a diet limited in energy content. Bulls in the experimental group (I) over the 63 days prior to slaughter were provided with ration energy limited to 80% of the maintenance requirement. Animals in the control group (II) received a balanced ration. Blood samples from all of the animals were collected 3 times (A, B, C). The decrease in the ration energy level did not have a significant effect on the concentrations of glucose, total protein, total cholesterol, high-density lipoproteins, triglycerides, and the activity of aminotransferase aspartate and aminotransferase alanine. Varied nutrition resulted in an increase in the content of albumins and urea (P < 0.01) in experimental group blood serum. The study did not show any significant changes in the insulin and thyroxine concentrations for the last blood collection date; however, a decrease in the triiodothyronine concentration was found (P < 0.05).
