environmental conditions. Milk samples (30 ml each) were collected
once weekly and milk samples were collected at 6:00 am and 6:00 pm
and mixed. Blood samples (10 ml each) were collected monthly.
Ambient temperature (AT, °C) and relative humidity (RH, %) were
measured two times daily (07:00 am and 2:00 pm) the maximum
temperature was recorded during summer where it was 39.93 ± 0.34. The
maximum relative humidity was recorded during summer where it was
74.62 ± 0.49 and the maximum THI was recorded during summer where
it was 96.32 ± 0.57 but the average was 80.37 ± 0.36.The maximum
average of weekly milk yield and sold not fat (S.N.F) were recorded
during THI was in no stress. The maximum average of milk fat (F) %
and protein % were recorded during THI was in heat stress. The
maximum average of IGF-1 was recorded during THI was in heat stress.
there was decrees in Cholesterol during THI was in no stress combating
to the other THI and the maximum concentration of T.P was recorded
during THI was in no stress combating to the other THI and the same
result was recorded in Albumin, Alb / Glo ratio and Glucose. There was
increase in Blood hemoglobin during THI was in no stress combating to
the other THI and the maximum concentration RBCs was
