A cow in Texas has apparently defied great odds and given birth to four calves. Jimmy Barling said on Monday that DNA tests would be done on tissue samples from the three bull calves and the one heifer calf to satisfy those who may question the births from one mother. "We knew she was pregnant, but we didn't know she was going to do this," the 76-year-old Barling said. "This was a shock. This blew our minds." Barling's wife, Dora Rumsey-Barling, owns the couple's 20 or so cattle outside of DeKalb, near the Arkansas and Oklahoma borders. Rumsey-Barling's granddaughter named the four black calves Eeny, Meeny, Miny and Moo, Barling said. Local veterinarian Mike Baird called the March 16 births "extremely rare". He said the odds of four live births from one cow were 1 in 11.2 million. Baird knows the couple well and is nearly certain the four came from one mother, rather than a nearby cow perhaps birthing one or two and then moving along so that it appeared the four came from the Barling's cow. "In the interest of science and the animal world, it's one of those things that need to be verified beyond a shadow of a doubt," he said. The couple watched the birth of the fourth calf after going to check on the mother when they saw buzzards circling above one of their fields. Because the mother cow was unable to nurse all four calves, the couple were relying on neighbours to help. Moo has stayed with her mother, while Eeny, Meeny and Miny are with two different caretakers. Meeny is the smallest, weighing in at about 11.3kg.
