Morphine at a dose of 0.25 mg/kg failed to produce detectable taste conditioning, and a somewhat higher dose of morphine, 0.42 mg/kg, produced CTA, if anything, rather than CTP.
It is an adaptation of the English module "Investing in Information for Development" produced by CTA, the Food and Agriculture Organization of the United Nations (FAO), GTZ (an international cooperation enterprise for sustainable development), the International Food Policy Research Institute (IFPRI) and the University of Wageningen.
