| Summary: | The aim of the paper was to study the influence of the calving season on the milk, butterfat and protein yield per normal lactation. Researches were carried out on 125 lactations from Romanian Black and White cows from the Didactical Farm Timisoara. Lactation were divided into the four seasons as follows: summer with 34 lactations, winter with 19 lactations, spring with 35 lactations, and autumn with 37 lactations. Results showed that winter calving cows produced the highest milk, butterfat and protein yields per normal lactation (4932.2 kg, 189.63 kg, and 153.79 kg, respectively). |
