title: Clinical study report on milk production in the offspring of a somatic cell cloned Holstein cow.
abstract: This study examined two female offspring of a somatic cell cloned Holstein cow that had reproduction problems and milk production performance issues. The two offspring heifers, which showed healthy appearances and normal reproductive characteristics, calved on two separate occasions. The mean milk yields of the heifers in the first lactation period were 9,037 kg and 7,228 kg. The relative mean milk yields of these cows were 111.2% and 88.9%, respectively, when compared with that of the control group. No particular clinical abnormalities were revealed in milk yields and milk composition rate [e.g., fat, protein and solids-not-fat (SNF)], and reproductive characteristics of the offspring of the somatic cell cloned Holstein cow suggested that the cloned offspring had normal milk production.
