In each pair, 1 member had had a twin pregnancy (T) and the other was a comparable cow with a single calf pregnancy (S). All cows were offered the same amount of feed over the first 28 weeks of lactation. In early lactation, intakes were equal; in mid-lactation the T group ate more. The T cows had a lower peak yield of milk than the S cows, but rates of decline in yield in mid-lactation were equal for the 2 groups. Lactose concentrations in the milk were equal throughout lactation, but the fat and protein concentrations were greater for the T group in early lactation. The T group yielded smaller amounts of milk solids. The T group lost less weight in early lactation and gained more weight subsequently. Three of the T group, but only 1 of the S group, did not conceive during the test lactation.<\/jats:p>","DOI":"10.1017\/s0022029900023074","type":"journal-article","created":{"date-parts":[[2009,6,5]],"date-time":"2009-06-05T06:54:47Z","timestamp":1244184887000},"page":"241-247","source":"Crossref","is-referenced-by-count":2,"title":["A note on the lactation performance of twin-bearing cows"],"prefix":"10.1017","volume":"50","author":[{"given":"William H.","family":"Broster","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.
