Evaluation of Nutritional Regime in Small-Scale Dairy Farms in Khartoum State, Sudan

A.M.A. Fadel Elseed, A.G. Mahala and Amel H. El Khaier
The objective of this study was to determine whether owners of small-scale dairy farm in Khartoum State feed their animals the required energy and protein. Calculated Crude Protein (CP) and Net Energy for lactation (NEL) requirements of dairy cows in fifty small-scale dairy farms located in Khartoum, Omdurman and Khartoum North were compared with the actual CP and NEL intake during the period of September to November 2006. The experimental design was completely randomized with 3x3 factorial arrangement of treatments. The cows of each locality (Khartoum, Omdurman and Khartoum North) were divided into three groups according to milk yield (low: 0-6 kg day-1; medium: 6-12 kg day-1; high: 12 kg day-1 and more). The average Crude Protein (CP) content of rations was 29.5, 24.66 and 24.05% for Omdurman, Khartoum North and Khartoum, respectively. Both the locality and milk yield had a significant effect (p<0.05) on protein oversupply which was lower for Khartoum (108.4%) than for Omdurman (180%) or Khartoum (141.9%). However, the least protein oversupply was 101.8% for high milk yielding cows. Producers in Omdurman, Khartoum North and Khartoum exceeded the total energy required for lactation by 81.4, 69.7 and 45.1%, respectively. The excess energy reached 100% of the total energy requirement for low milk yielding cows. In conclusion, all producers in small-scale dairy farms in Khartoum State feed their herds excess amounts of CP and energy. Therefore, guidelines need to be developed for optimal production efficiency.
