Fish oil in pig food
fatacidA dataframe.
A fish oil fatty acid X14 has been added in
different concentrations to the food for pigs in a
study. Interest is in studying how much of the fatty acid can
be found in the tissue. The concentrations of x14 in the
food are verb+dose+={0.0, 4.4, 6.2, 9.3}.
The pigs are fed with this food until their weight is 60 kg. From thereof and until they are slaughtered at 100kg, their food does not contain the fish oil. At 60kg (sample=1) and 100kg (sample=2) muscle biopsies are made and the concentration of x14 is determined. Measurements on the same pig are correlated, and pigs are additionally related through litters.
