Abstract
A total number of 160 Egyptian Balady sheep, 3-5 years age
of both sexes were included in this study. The study run into two parts:
First part, {field study): included 100 animals, that were sub-
divided into 2 groups: 1~ group proved to be clinically healthy
by both clinical and laboratory methods of examination and served
as control. The 2nd group was admitted to the veterinary clinics
in-Assiut and suffered from ruminal dysfunction. Second part, (experimental study): including 60 animals belonged
to the clinic of Vet Med. Dept. Animals were given different types of rations in an abnormal amounts to induce experimental impaction while healthy animals were kept as a control.
Samples of blood sera were collected from all field and ex-
perimental animals to estimate total protein (gm%), albumin
(gm%), globulin (gm%), albumin/globulin ratio, electrophoresis
(%) calcium (mg%), inorganic phosphorus (mg%)_, magnesium (mg%),
sodium (mmol/L), potassium (mmol/L) and chloride (mmol/L).
Ruminal juice samples were collected from each animal to
study the physical properties of the juice including color, odour
and consistency, microscopic examination of protozoa, detection
of hydrogen ions concentration and biochemical analysis of total
protein (gm%), alhumin (gm%), globulin (gm%), albumin/globulin
ratio, calcium (mg%), inorganic phosphorus (~g%), magnesium
(m9%), sodium (mmol/l), potassium (mmol/l) and chloride (mmol/l).
