Out of the first roughly 100 cows that gave birth on his ranch near Sharon, 19 had twins, for a rate of about 20 percent.

North Dakota rancher Chris Johnson is seeing double a lot this spring.

Out of the first roughly 100 cows that gave birth on his ranch near Sharon, 19 had twins, for a rate of about 20 percent. Typically, the rate for twin calves is about 3 percent.

Johnson tells Agweek (http://bit.ly/YPR3W2 ) that twin calves are more curse than blessing because they usually require more care and attention than single calves. He says the extra time, effort and expense associated with a twin usually more than offsets the value of the second calf.
