Milk urea concentration as a tool for optimising crude protein content in dairy goat diets: a path to sustainable milk production

Milk urea concentration (MU) has been extensively studied and is often used to evaluate energy protein balance in dairy cattle diets, but not this extent goat diets. The aim of study was determine the relationship between MU crude content (CP) diet Alpine goats order reduce excessive nitrogen excretion from organism. For purpose, 72 were randomly divided into three equal groups (24 animals) fed a concentrate mix containing 14%, 16%, 18% CP, respectively. chemical composition milk samples determined ratio fat calculated. Statistical analysis data performed using MIXED procedure (SAS V8 software package). Increasing CP 14% 16% increased daily yield by 0.4 kg (p<0.001), 35.01 41.24 mg/100 mL (p<0.001). Based on calculated inflection point milk, range 40.00 45.00 can be considered optimal good indicator balanced for goats.
