Gestation length on a beef cow is another one of those numbers where the average is seldom seen. The gestation length for all breeds of cattle averaged together is 283 days. The range is 279 for Jersey and up to 292 for Brahman.On the average, the Continental breeds of Charolais, Simmental and Limousin exhibit gesta-tion lengths of 289 days.wenty-three percent were born be-tween 279 and 283 days of gestation, while only 13% were born between 284 and 291 days of gestation. The average gestation length on all 140 of these calves was 279 days, four days less than the 283 breed average.
1 In comparing the gestation periods of the above cows with the gestation periods of the calves they produced, it was found that four of the eleven eases showed a decided tendency for the calves of a cow to have gestation periods similar in length to her own. 6. 2  The least variation in length of gestation observed for 29 cows that had each produced six or more calves was six days. 3  The greatest variation was 20 days. 4  The length of gestation periods of some cows were quite uniform, while others varied widely.
