A major physiological adaptation of the camel is its ability to allow its body temperature to fluctuate. The normal diurnal variation in a fully hydrated camel does not exceed 2°C and is in the range of about 36 to 38°C. In a 500 kg animal the heat stored as a result of diurnal variation of this order would be about x 106 (joules). In dehydrated camels, when considerations of energy and water conservation become more important, temperature variation can be as much as 8°C in the range of 34 to 42°C, but a more normal range is 6°C. | Milk Production of Hand-Milked Dairy Cattle in Burkina Faso VINSOUN MILLOGO Faculty of Veterinary Medicine and Animal Science Department of Animal Nutrition and Management Uppsala Doctoral Thesis Swedish University of Agricultural Sciences Uppsala 2010 Acta Universitatis agriculturae Sueciae 2010 4 Cover Description of photograph Dr Sigrid Agenas 2007 photo hand-milking in Burkina Faso ISSN 1652-6880 ISBN 978-91-576-7481-4 2010 Vinsoun Millogo Uppsala Print SLU Service Repro Uppsala 2010 Milk Production of Hand-Milked Dairy Cattle in Burkina Faso Abstract The overall aim of the present thesis was to improve milk production and milking routines in Burkina Faso. There is a long tradition of keeping livestock in Burkina Faso and there are large numbers of cattle in the country. However Burkina Faso today depends on the import of meat and milk and the domestic production is greatly in need of improvement. The first in this thesis study was a survey that aimed to investigate the current situation in dairy farming and milk processing in periurban areas of Burkina Faso. Two experimental studies and two field studies were designed to answer questions arising from the survey. Day-to-day variation in milk yield and milk composition was determined in ten multiparous Zebu cows. Three different hand-milking techniques identified in the survey were compared in twelve Zebu cows milked by three different milkers. A milk recording pilot study was carried out on ten farms with a total of 79 cows. Finally milk hygiene was investigated along the dairy chain from the cow to the dairy or market. The main constraints on milk production in peri-urban areas of Burkina Faso are low availability of feed and water lack of selective breeding milking management and lack of infrastructure. The milking routine was hand-milking and restricted suckling in both traditional and semi-intensive systems. The pilot milk recording data suggested it would be possible to improve milk production through .
