摘要：For the purpose to put the focus on the impact of feeding diet and the race on the dairy production of milk in the commune of Mograne (Gharb region, Morocco), a farm holding has been persuaded to be subjected to diet for 12 months in 2008. The owner was already convinced to integrate the Holstein breed in 2006 for the five lactating cows. We have calculated the milk production of the holding during the period January-December 2007 as a proof for comparison, where cows have been feeding randomly according to the offer and depending on the season. We were feeding throughout the period of study by alfalfa during the winter period, and the wheat for the summer period. The five cows submitted in this study are of type Holstein. The results recorded during 2008 were very suitable. The production of milk was increasing from 18742 liters in 2007 to 29716 liters in 2008, scoring an increase of 37%. The physicochemical analysis and microbiological conducted before the driving program and after have recorded the results very convincing.
