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, haematocrit, 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.
