Abstract

Nowadays consumers are highly interested in the quality of the products they eat, especially when this refers to meat so this current analysis is a review of the anaemia as a factor affect meat quality in ruminants. Out of (135) cattle of different ages, sexes and breeds from different localities, (farms and abattoirs) in Ismailia Governorate found forty eight animals were anaemic. All these animals were examined clinically and laboratory to determine their situations of anaemia and parasitic infestation. Animals were classified into three groups, 1st group were healthy cattle free from blood parasite (n=25) used as control group, 2nd group were suffering from Theileriosis (n=28) and 3rd group were suffering from Babesiosis (n=20). Two blood samples were collected from each animal for determination of erythrogram and leukogram changes and some biochemical parameters in separated sera. The results of the hematological picture revealed a significant reduction in RBC, HB, PCV, MCV and MCH in cattle infected with theileriosis. Babesiosis induced significant decreases in RBC, HB and PCV with insignificant changes in MCV, MCH and MCHC (normocytic normochromic anaemia) while theileriosis induced significant increase in MCV and decrease in MCH and MCHC (macrocytic hypochromic anaemia). Bovine infected with theileriosis and babesiosis revealed leukopenia and neutropenia accompanied with lymphocytosis compared to control group. The result of biochemically analysis showed that cattle infected with theileriosis and babesiosis revealed significant reduction in total protein, albumin, globulin, glucose and iron levels associated with significant increase in the activities of liver enzymes AST, ALT, total bilirubin, urea and creatinine. The muscle samples which were taken from slaughtered anaemic cattle, examined physico-chemically and sensory properties, found that pH and (TVBN) values were significantly high whereas the moisture, protein and fat percent were decreased accompanied with reduction in (TBA) and iron percent. The muscle from the healthy control group had significantly higher scores for tenderness and overall likeness than those from the other anaemic groups. So it is recommended that the animal showing signs of systemic disturbance and elevated temperature should not be slaughtered but retained for treatment, preferably outside the meat plant.
