Abstract/OtherAbstract:
The production of milk, fat and protein of 37216 mothers of twins was compared with that of 1 691 127 mothers of single calves of Black and White breeds of cattle recorded in England and Wales. At every parity, the mothers of twins produced more milk, fat and protein than the mothers of single calves. The proportion of twin-bearing cows retained increased with parity, from 0.67% at first calving to approximately 40% at the tenth or eleventh calving. More mothers of twins achieved 305 d of lactation subsequently than mothers of single calves, although their inter-calving intervals were not generally longer.
