Figure 3.

Growth of artifically-reared pigs from representative experimental groups overlayed onto growth curves developed from the Artificially Reared Reference group animals. The blue and red lines represent ad libitum-fed pigs on an iron sufficient or deficient diet (20). The black line represents scheduled-fed pigs supplemented with a prebiotic combination (polydextrose and galactooligosaccharide) (16). The yellow line represents scheduled defined-fed pigs supplemented with prebiotics and milk bioactives (17). Lastly, the green line represents pigs that exhibited failure to thrive. The body weight of these pigs did not increase within two weeks of study enrollment, resulting in humane euthanasia. All together, the plotted cases represent accelerated growth (blue), typical growth (black and yellow), reduced growth (red), and failure to thrive (green).
