| Popis: | The present study aimed to evaluate biometric measurements and blood and hormonal parameters of Santa Ines lambs. Thirty lambs with an average live weight of 13.0 ± 1.49 kg and 60 days of age were used to estimate glucose, cholesterol, β-hydroxybutyrate, urea N, total protein, albumin, globulin, chloride, calcium, phosphorus, magnesium, and leptin, insulin, and thyroxine (T4) hormones. Lambs were assigned to a randomized complete design in a 3 × 2 factorial arrangement consisting of three levels of food restriction (FR) (control, 30%, and 60%), three collection periods corresponding the age of the animals (14, 18, and 23 weeks of age), and two sex categories (castrated and uncastrated). Blood was collected by jugular venipuncture in the three collection periods. For biometric measurements, a randomized complete design in a 3 × 2 factorial arrangement was adopted, taking into account restriction levels and sex categories. Measurements were taken every two weeks throughout the experimental period. The hormone thyroxine was not influenced by age, diet, or sex category. Leptin and insulin increased with the animal age (P |
