Summary and conclusions

The results of experiments conducted on 156 swine, from time of weaning till bacon weights were reached, are reported. One hundred and twenty of these animals were subjected to complete dietary control as regards the quantity of food consumed and the composition of the diet.

Twenty-nine treatments, consisting of different amounts of Ca, P and vitamin D added to an otherwise adequate diet, were imposed.

The reaction of the animals to the treatments was studied in relation to growth (increase in weight), appetite, utilisation of the food, the blood picture (concentration of serum Ca, blood inorganic phosphate, serum phosphatase and blood Hb), and the morphology and chemical composition of the bone. The results obtained are summarised in Table XVIII.
