### Usage

    dietox

### Format

This data frame contains the following columns:

Weight

  Weight

Feed

  Cumulated feed intake

Time

  Time (in weeks) in the experiment

Pig

  Id of each pig

Evit

  Vitamin E dose

Cu

  Copper dose

Start

  Start weight in experiment, i.e. weight at week 1.

Litter

  Id of litter of each pig

### Details

Data contains weight of slaughter pigs measured weekly for 12 weeks. Data also contains the startweight (i.e. the weight at week 1). The treatments are 3 different levels of Evit = vitamin E (dose: 0, 100, 200 mg dl-alpha-tocopheryl acetat /kg feed) in combination with 3 different levels of Cu=copper (dose: 0, 35, 175 mg/kg feed) in the feed. The cumulated feed intake is also recorded. The pigs are littermates.
