dc.description.abstract As in other tropical countries, importation of pure-bred exotic temperate cattle breeds for upgrading or promotion of animal production in the Sudan has been a controversial issue for a long time. Exotic bulls were imported into the country as early as 1925, but only during the last decade has frozen semen of European breeds been imported. The high risk of climatic stress and susceptibility to enzootic diseases discouraged the establishment of European breeds and their crosses with local types. However, despite the cautious advice by veterinarians and the authorities concerning that risk, some private companies and individual farmers have recently decided to import European Friesian cows into the country. IMPORTED ANIMALS AND THEIR MANAGEMENT A group of six two-year old pregnant Friesian heifers were purchased by a competent farmer and imported from Germany into the Gezira (Latitude 14°24'N, Longitude 33°29'E, 407 meters above mean sea level) in the Central Region of the Sudan during the third week of October 1984. The animals were flown from Germany by a normal cargo aeroplane. On arrival at Khartoum airport the animals appeared to be in excellent health and condition. Immediately after arrival the animals were loaded and transported by truck during the night to their destination, a distance of 190 kilometers south. The truck was open from all sides except for the heavy cross and side iron angle bars. These bars were padded with cloth to prevent possible injuries. The floor of the truck was made of hardwood. The animals were left loose in the truck, and lay on the floor for most of the journey. The new environmental conditions were excellent: The animals were kept in a clean, acaricide-sprayed, sand floored, 8x9 metre pen. The pen was covered by a 4 metre high corrugated iron ceiling and a thatched roof and surrounded by a 11/2 metre high brick wall, leaving adequate ventilation all around. The temperature in the pen was lowered to 25°C by a cold current of air ducted through a watercooler and circulated by ceiling fans. The outside average ambient temperature and relative humidity at that time of the year were 33.4°C and 39% respectively. en_US
