Manage your herd's health dynamically: calculate expected calving dates, schedule vaccine alerts, estimate weight using chest measurements, and model dry-matter feed requirements.
The average pregnancy gestation period for standard indigenous dairy cows is 283 days (ranges 279-287), and for buffaloes is 310 days. Setting a dry period is crucial to give the animal's mammary tissues rest and boost next-lactation yield.
Separate the pregnant cow around 10 Feb 2027. Transition feed to high-quality dry fodder + mineral mix.
Administer pre-calving booster on or around 12 Mar 2027 (30 days before birth) to build colostrum antibodies for calves.
Ensure clean, soft-bedded calving pen from 1 week prior to 11 Apr 2027. Keep calcium gel ready.
The average gestation period of a dairy cow is 283 days (about 9.5 months). Indigenous Indian breeds like Gir, Sahiwal, and Kankrej typically range between 279 and 287 days. Buffaloes have a longer gestation period, averaging around 310 days.
Milking should be stopped 60 days before the expected calving date. This "dry period" allows the mammary tissues to repair, gives the cow a chance to rebuild body nutrient reserves, and ensures high-quality colostrum for the newborn calf.
You can use Shaeffer's formula: Weight (lbs) = (Girth in inches x Girth in inches x Length in inches) / 300. Multiply the result by 0.4536 to convert to kilograms. Heart girth is measured right behind the front legs, and length is from shoulder point to rump point.
