§ Mr. MorleyTo ask the Minister of Agriculture, Fisheries and Food what are the differences in amounts of protein, casein and fat levels in milk coming from a dairy cow treated with synthetic bovine somatotropin and a dairy cow not treated with synthetic BST.
§ Mr. SoamesMany studies have been carried out to examine the effect of manufactured BST on milk composition. A review of those studies, which includes details of the amounts of protein, casein and fat, is to be found in the proceedings of the BST world-wide symposium held in August 1989 and reproduced in the "Journal of Dairy Science (1991), Volume 74 (Supplement 2), pages 2 to 11, a copy of which I have placed in the Library of the House.
§ Mr. MorleyTo ask the Minister of Agriculture, Fisheries and Food what research has been undertaken into IGF-1 levels in cows treated with synthetic BST; and to what extent these levels are different from those in cows not treated with synthetic BST.
