You are watching: What is the gestation period for a cow

"The regular gestation period of the dairy cow is 283 days. Based upon studies make by the Ohio Experiment Station, however, it is apparent that over there is variation among breeds. The adhering to figures present the gestation period by breed, as found in this experiment: Ayshire, 278 days; Brown Swiss, 288 days; Guernsey, 283 days; Holstein, 279 days; and Jersey, 278 days. The Ohio station additionally reported (1) that the gestation period of first-calf heifers is about 2 days less than the of larger cows of the respective breeds, and also (2) that the gestation duration where bull calves are born is around 1 day longer than where females room born." ~M.E. Ensminger, Dairy livestock Science
​Since over there are five heifers and also cows calving top top Birdsong farm yard in the next 5 months,I figured this to be a great time to share my gestation calendar, i beg your pardon I"ve custom designed for Jerseys.​
​The an initial column, breeding Date, is the day that her heifer or cow is bred. The 2nd column, Cow early out Date, is the date that your cow is due, while the 3rd column, Heifer due Date, is the date that her heifer is due. The 4th column, Dry turn off Date, is the date for your cow"s final milking if friend are giving her a 60-day dried period.​For example, ns bred Birdsong Princess Diana, a heifer, ~ above June 20th, therefore she will certainly be early out on march 23rd. I bred Birdsong autumn Aster, a cow, top top September 22nd, therefore she will certainly be early out on June 27th and I will want to dry she off by April 27th to give her a 60-day dry period. Click the images listed below to take it a closer look.


I trust that this gestation calendar will certainly make it simpler for friend to calculation the due days for your Jersey heifers and cows, keeping in mental that because cows and also heifers carry out not review very couple of will in reality calve on your due date! (A selection of 7 days prior to to 7-14 work after the due day is typical.)Leave a comment below and also share whereby in the people you farm and also what breeds of livestock you raise.
