Basal Ration

In experiments conducted to determine the requirements of chicks for vitamin A up to eight weeks of age, vitamin A was supplied, in addition to the basal ration, by oral administration of Reference Cod Liver Oil at the rate of 25, 50, 75 and 100 International units per day. It was found that chicks receiving 75 units of vitamin A per day grew at a normal rate and did not show any signs of vitamin A deficiency. The chicks that received the basal ration only, showed symptoms of avitaminosis A at three weeks of age, while the group receiving 25 international units per day at eight weeks clearly had not received a sufficient supply of the growth factor.

Fattening Pigs

The efficacy of three sources of vitamins A and D supplements was tested in an experiment with fattening pigs involving the following four treatments :(1) Control—basal meal.(2) As control, but at one week of age the pigs had been given a single intramuscular injection of a commercial preparation, supplying 500,000 i.u. of vitamin A and 100,000 i.u. of vitamin D3.(3) Basal meal + 1 % cod-liver oil (containing 500 i.u./g. of vitamin A and 68 i.u./g. of vitamin 3), supplying 2,270 i.u. of vitamin A and 309 i.u. of vitamin D3 per lb. of diet.(4) Basal meal + synthetic vitamins A and D concentrate (containing 50,000 i.u./g. of vitamin A and 5,000 i.u./g. of vitamin D3), added to supply 2,250 i.u. of vitamin A and 300 i.u. of vitamin D3 per lb. of diet.The basal meal which was the standard fattening diet used at Shinfield consisted of: fine miller’s offal 50, barley meal 30, flaked maize 10, white fish meal 10, all parts by weight. It should be noted that the diet contained a precursor of vitamin A, and it was calculated that this would provide about one-third of the recommended allowance of vitamin A for fattening pigs.
