Harris's hawks () hematological parameters in different tropical locations.

This work described and compared the hematological findings of 25 clinically healthy Harris's hawks () in captivity at two different tropical locations: 16 samples from Aguascalientes, which altitude is 1878 mean sea level, and nine samples from Amecameca which altitude is 2650 mean sea level. Blood samples were collected from the brachial vein of each raptor under physical restraint. Significant differences between the two locations were found in some parameters including total, erythrocytes, heterophils, basophils, lymphocytes, and heterophil/lymphocyte ratio.

sperm storage with poultry oviductal secretions.

In the hen oviduct, tubules have been identified that preserve the sperm, maintaining viability for up to 15 weeks. This study aimed to evaluate the physiological status of rooster sperm when preserved with uterus vaginal junction secretions (UVJS). Males and females of the Rhode Island breed were used.
