Abstract:
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.
