PHYSIOLOGICAL STUDIES ON THE LEVEL OF SOME ELECTROLYTES AND ENZYMES IN NORMAL AND NEWCASTLE VACCINATED CHICKS

was designed to study the normal levels The present investigation
enzymes and electrolytes in Hubbard chicks, and the of some serum effect of vaccination with Newcastle vaccine for a period of six weeks to clarify if there is any harm inflected upon the heart or liver.
The data obtained from this study revealed that :
level of alkaline phosphatase in normal chicks 1. The serum
decreased gradually by age. While in is high in the first week then vaccinated chicks the level was increased at the second week post

vaccination.
2. Serum acid phosphatase was higher in vaccinated chicks at the first two weeks of age then decreased.
3. Vaccination with NDV was accompanied with a rise in the level of SGOT.
4. The level of serum GPT of vaccinated chicks at one week of age was higher. But SGPT level in non vaccinated chicks was raised at the second week and became undetectable till the end of experiment. While invaccinated ones the levels were variable.
5. Levels of LDH in serum of vaccinated chicks were increased.
6. The values of inorganic phosphorous in serum tend to be decreased with age in non vaccinated and vaccinated chicks.
7. A significant rise in serum calcium level was observed from third week in vaccinated chicks.
8. The mean values of serum sodium were raised in vaccinated chicks.
9. Serum potassium level was increased in both vaccinated and non vaccinated chicks.
It could be concluded that vaccination against ND by using B, strain on the first week old chicks and lasota a strain on 21 and 31 days is of great value in rearing the Hubberd chickens in Egypt. To overcome such early rise of some enzymatic levels due to a momen tary liver dysfunction by prescribing lypotropic drugs at the early stages such as those rich in vitamin B2, inositol and choline.
