Some Haematological studies on Camel Foetal Blood

The present investigation is concerned with the de- velopment of the blood picture and certain biochemicalconstituents of foetal blood of camels (Oamelus dromedar- ius) as well as those of adult sh&4camels. The development of the haemopoietic activity of the liver, spleen, thymusgland and bone marrow waS also studied.Camels foeti were classified according to their vertebral column length (~) into five groups. Samplesof foetal blood and haemopoietic organs were oollected from foeti of clinically healthy mothers at Oairo slaughter houseThe present work revealed the following findings:-1- The mean values of erythrocytes were increased as foetal growth advanced i,e. 4.388 t 0.34 millions/ulin the first group and 9.50 ± 0.54 millions/ul in the last one. The increase waS at a rapid rate i~ thesecond stage then it continued at a slow rate in the later stages. The average value of erythrocyticcount in adult she-camels waS generally lower than that of the foeti.2 - The haemoglobin content and packed cell volume were signigicantly increased throughout foetal growthstages in comparison with the first ~tage. It waS observed that the mean values of Hb. and P.C.V werehigher in;the Ioetal blood than of adult she-camelsblood except in the first stage of foetal development.
