Atharva Veda 3.28: A charm to change the ill-omened birth of twin calves into a blessing

This cow was born to bring forth offspring singly, though they created kine of every colour.
When she produces twins in spite of Order, sullen, with groan and grudge she harms the cattle.

She brings destruction on the beasts, turned to a flesh-devouring worm.
Yes, give her to the Brāhman that she may bring luck and happiness.

Be thou auspicious to our folk, bring luck to horses and to kine.
Auspicious unto all this farm, bring luck and happiness to us.

Let there be rain and increase here, here be thou most munifi-cient.
Mother of twins, prosper our herd.

Where, having left all sickness of their bodies, the pious lead, as friends, their lives of gladness Nigh to that world approached the twin calves' mother. Let her not harm our people and our cattle.

Where lies the world of those dear friends, the pious, those who have brought due sacrifice to Agni Nigh to that world approached the twins calves' mother. Let her not harm our people and our cattle.
