II. Case Study JF - Revista de Producción Animal JA - RPA VL - 26 IS - 3 SE - Genética y Reproducción DO - UR - https://revistas.reduc.edu.cu/index.php/rpa/article/view/1404 AB - The bio-economic behavior of 10 commercial dairies was assessed as to forage production, and annual calving patterns. Dairy No. 3 was used as a comparison model in a case study, based on in previous studies results (2011) where it stood out from the rest, with 86 % calving pattern in the April-August period. To determine the influence of the calving pattern oriented to the rainy season, on the production and bio-economic efficiency indicators, the behavior of dairy no. 3 in 2011 was compared with its mean values for the previous years; the means of dairies grouped in pat-terns I and II, and the mean of dairies in pattern III, without the case study unit. The results indicated that dairy No. 3 reached higher gross profits than the rest, concerning productive efficiency (1 298 kg of milk/ha and 32 975 kg of milk/worker or working unit (UT)), with higher income from milk sales, income-expenses, and lower costs of milk production (0.84 CUP/kg of milk). These results are linked to a more favorable calving pattern this year. ER -
