Late pregnancy is a critical period in prolific ewe, due to the metabolic and hormonal changes necessary for fetal development. These variations in physiological status affect the normal hematological values of animals. In addition, factors such as age, parity, and aliment also influence these hematological values. This paper details a study carried out on 74 ewes, of Rembi breed, aged 2 to 7 years old, and situated in semi intensive system coming from 10 farms in the region of Tiaret. The choice of ewes reaching the third trimester of pregnancy was made randomly in order to assess the changes in hematological profile of the ewes during this period, and the influence of certain factors on the latter. An increase in white blood cell WBC (18.3 × 103 / mm3), characterized mainly by an increase of neutrophils and monocytes, and decrease in haematocrit (Ht), haemoglobin (HB) and red blood cell (RBC) values compared to normal values, were recorded. Statistical analyzes showed an influence of farm, type of aliment, and parity on the values of WBC, RBC, HB and Ht. The end of gestation in prolific sheep requires improvement in terms of type of aliment and hygiene in order to avoid anemia, metabolic diseases and infectious diseases. [ABSTRACT FROM AUTHOR]

The Barb horse this famous Maghreb horse, symbol of the pride of the Berber peoples It is particularly significant in the Algerian history, tradition and culture. This study consists in establishing the hematologic values specific to the Barb horse in the national stud farm "Chaou-Chaoua" in Tiaret. Algeria. Age of the study animals varied between 1 and 23 years. The effects of age and sex were analyzed by dividing animals into four groups, A (1 - 2 years, n=5), B (3-5 years, n=5), C (5-10 years, n=5) and D (11-23 years, n=5); for females and E (2 - 3 years, n=5), F (5-7, n=5), G (10, n=5) and H (11-25, n=5) for males. Animals studied were clinically healthy. A blood sampling was carried out from all study animals, the following hematologic variables have been determined: erytrocytes (RBC), hematocrit (Ht), hemoglobin (Hb), mean cell volume (MCV), mean corpuscular hemoglobin concentration (MCHC), mean hemoglobin content (MHC), white blood cells (WBC), neutrophils, eosinophils, basophils, lymphocytes, monocytes, platelets, total number of platelets (PLT) and mean platelet volume (MPV). The obtained results showed that the hematologic values are within established standards for the other breeds of hot-blooded horses; these values approached the lower limits of the standards for the RBCs, HCT, Hb, WBCs and the lymphocytes. Statically significant (P<0.05) differences were observed between females in different age groups for the MCV, MCHC, Platelets and the MPV. Groups of males showed significant differences for lymphocytes and platelets and between males and females, significant differences related to the MCV, Neutrophils, Basophils Monocytes, Platelet and the MPV. This research showed that these hematologic parameters are weak, they approach the lower limits of the standards and that neither the age, nor the sex seem to have an influence on the hematologic values of the Barb horse.
