Classification of dairy units belonging to the Basic Units of Cooperative Production in Ciego de Avila, Cuba


A case study was performed to classify the dairy units belonging to the Basic Units of Cooperative Production (UBPC) of the Ciego de Avila province, Cuba. A data matrix was created with physical, productive, and efficiency variables in 72 dairy farms. Principal components (PC) and hierarchical clusters methods were used for the formation of the clusters. Eight PC accounted for 87.7 % of the variance. The amount of cows and the milk yield accounted for 23.1 % of the variance in the PC1; and the dimension of the farm and the efficiency in the land use accounted for 19 % in the PC2. Six clusters of dairy farms were obtained. The 1 included 80.5 % of the cases and had lower total production, with 33.7 thousands of L, only 2.8 % of areas with improved pastures, 3 % with forages, and 242 L/ha. The cluster 3 with two cases, and the 4 with six, had higher efficiency, with 522 and 400 L/ha and 39.8 and 53.9 % of areas with improved pastures, respectively. Six clusters of dairy systems were classified according to the amount of cows, the annual milk yield, the land use efficiency, and the quality of the feeding basis. The dairy system based on natural pastures was predominant with lower efficiency, where the control of indices of sustainability should be applied and strategies of technological management should be elaborated.
Key words: milk yield, dairy farms, multivariate analysis, efficiency.
