These sectors base part of their economy on the sale of raw milk; however, several obstacles arise, with low daily weight gain and the calving interval being among the main challenges, along with issues related to indiscriminate reproduction due to the lack of prior selection of breeding stock. Monthly data was collected on various expenses such as feed, transportation, and healthcare from a total of 16 producers to determine the cost of producing 1 liter of milk. Additionally, information was gathered on the daily weight gain of 72 animals and on milk production and density in 26 animals. All this information was analyzed to identify the total production costs and to determine the monthly profit for each herd. We also estimated the genetic value in relation to our objectives—Daily Weight Gain, Milk Density, and Milk Production in 305 days—using the BLUP model. The results obtained show an average production cost of $0.22, while the average profit obtained is $109.19. Therefore, we selected milk production as the selection index. Additionally, we identified a calf with a daily weight gain of 561 g/day, along with two females producing 727.31 and 730.44 liters of milk, showing a selection response of 2930.31 and 2933.44, respectively. We conclude that the cows Clemencia and Negrita meet the selection index for milk production in 305 days, and therefore, their genetics could be disseminated to improve the production systems of the various producers in the sector. |
