Abstract
This experiment was conducted to evaluate the effects of ambient temperature and coriander seed supplementation on blood parameters and rectal temperature of Sasso T44 and Koekoek. Two experiments were conducted. The first (growers) experiment was conducted from 9 to 20 weeks of age and the second (layers) experiment was continued from week 21 to 40. In both experiments, breeds were exposed to two temperature rooms, heated and normal ones. Breeds were also further randomly allocated to three levels of (0 g·kg-1, 5 g·kg-1 and 10 g·kg-1) coriander seed powder supplementation. The data for both experiments were subjected in a 2 × 2 × 3 factorial arrangement. Exposing growers to the heated room showed a significantly higher (P < 0.05) level of creatinine, alanine aminotransferase and mean corpuscular hemoglobin concentration than those in a normal room. However, the temperature had no effect (P > 0.05) on blood serum and hematological parameters of layers. Decreased glucose and cholesterol levels were observed in growers supplemented with 10 g·kg-1 of coriander seed. Similarly, the 10 g·kg-1 of coriander seed supplementation reduced (P < 0.01) white blood cells in growers but increased hemoglobin in layers. The results indicated that temperature and coriander seed supplementation varied some of serum and hematological parameters with the effect being more observed in growers than in layers.
