Changes in the relationship between the external structure of the udder and milk yield and ease of milking in three successive lactations of Polish Black-and-White Lowland cows



Changes in the relationship between the external structure of the udder and milk yield and ease of milking in three successive lactations of Polish Black-and-White Lowland cows



Annales Universitatis Mariae Curie Skodowska, EE Zootechnica 1988; 2: 75-85



In 110 cows the phenotypic correlations of 100-day and whole-lactation milk yield with udder length, depth, width and vol. decreased between lactations 1 and 3 but were all positive and almost all significant at P<0.01 (ranging from 0.127 to 0.644).
