### Diet Suggestion for Dairy Cow of a Body Weight of 400 kg\({}^{0.75}\)  
Table 5 shows total dry matter according to lactation stages, DM intake, and the body conditions score (BCS). Dairy cow total DM intake was 13.3 kg, 14.5 kg, and 9.5 kg for early, mid, and end lactation, respectively. At the same time, the fluctuation in BCS was \(-\)0.46, \(-\)0.22, and +0.45 according to the course of lactation. There was a good balance between the milk footprint unit and the degradable nitrogen in small intestine and the energy degradable proteins in the small intestine were in good balance with the milk footprint unit, with an average of 123.6 and 113.3, respectively.

Table 3: Nutritive values of dominants ingredients used by dairy farmers.  
Table 6 shows the amount of DM according to forage and concentrates. For forage, the DM (kg) was 6.73, 8.0, and 5.7 kg for early, mid, and end lactation, respectively. For concentrates, the amount of DM was 6.59, 6.5, and 3.8 kg. The expected milk yield for the respective amount of DM was 13.5, 15.5, and 0.0 kg. During the end of lactation, the cow was dry and not giving milk at all. The feed intake was higher during the early and mid-lactation and corresponded also to high milk yield. This calculation was conducted from data collected from locally available forages and concentrates in the peri-urban area of Ouagadougou (Burkina Faso).
