This self-instructional audiotutorial module though designed for ILCA's course on rural dairy processing, will have wide application in organisations with students and professionals involved in dairying in Africa. The objectives of this module are to recall the major components of milk and descri...

The predicted performance of nine crossbreeding strategies for milk production and reproductive traits and cow live weights (LW) were compared. The strategies were selected because of their superiority to many others. The data were from crosses of Ayrshire (A), Brown Swiss (B), Friesian (F) and S...
