Lactation Curve PowerPoint PPT Presentations

Lactation curve is defined as a graphic representation between milk production and lactation time starting from day of calving to dry period. The lactation curve is used to predicting of the peak milk yield, lactation persistency, total milk yield and days in milk. Lactation curve can also be used in breeding programs, herd nutritional management, decision regarding culling of animals.

Vrindavani cattle are recently developed synthetic crossbred cattle strain of India (50-75% exotic inheritance of Holstein-Friesian, Brown Swiss, Jersey and 25-50% indigenous inheritance of Hariana cattle). Different lactation curve models such as Ali & Schaeffer (AS), Cobby and Le Du (CL), Sikka (SK), Mitscherlich x Exponential (ME), Mixed log (ML), Wilmink (WL) and Wood (WD) models were fitted to daily test day milk yield (DTDMY) records of 404 Vrindavani cattle.
