Abstract
The epidemiology, haematological and and biochemical
changes in blood and pattern of rumen fermentation in low milk
fat syndrome cows were studied.
Ten cases (below 3.5% milk fat) and six control animals
(above 3.5% milk fat) were investigated. Rumen liquor, blood
and composite milk samples were collected on three occasions
viz. 30th, 60th and 90th day of lactation and selected
parameters were studied.
There was no significant difference in the physical
characters, pH, SAT, MBRT protozoal motility and protozoal
count of rumen liquor. Significant reduction in the rumen
total volatile fatty acid and the acetic:propionic ratio (A:P)
was noticed in the low milk fat group. Significant decrease
in acetic acid and increase in propionic acid was observed in
the low milk fat group.
There was no significant difference in haemoglobin,
haemotocrit, and TEC between the control and low milk fat
groups. No significant difference was noticed in the serum
triglycerides, cholesterol and glucose level between the
control and low milk fat groups.
