In order to provide an up-to-date perspective on farm management techniques, a survey was conducted in a dairy cattle farm to study the relationships between management practices, milk yield and quality. A number of 310 Holstein Friesian cows reared for milk production in a semintensive farming condition were taken into study. Over the course of a year, individual milk analyses were performed on CombiScope FTIR milk analyzer (Delta Instruments, Netherlands). Milk yield per milking session was recorded daily using the AfiMilk system (Kibbutz, Israel). The analysis and interpretation of the results were correlated with the numerous observations made directly on the farm. The average calculated content, per normal lactation, was 8887.79 kg of milk, 369.05 kg fat, and 306.06 kg protein. A strong, positive relationship between milk yield and fat content, which means that an increase or decrease in milk production results in a corresponding change in the amount of fat contained. The yearly average percent of fat was 3.99 %, protein 3.32 %, casein 27.75 %, lactose 4.9 %, SCC 195,900 cells/ml were obtained in the studied farm.
