Abstract


Effects of cows age on milk yield fat and protein percentage was studied in Romanian Black and White breed. Onaverage cows produced 5125 kg of milk with 3.87% fat (198.46 kg) and 3.18% proteins (163.48 kg). The highestyield was reached at the third lactation, when cows produced (5705 kg milk, 219.2 kg milk fat, and 184.2 kgproteins). Cows produced with 1052 kg (p<0.001) more milk during the third lactation than in the first lactation and650 kg (p<0.05) more milk than in second lactation.
