Best Time to Increase Bovine Calving Based on Dairy Indicators of Commercial Herds in Camagüey

The best time to increase calving based on dairy production indicators was determined. Records from 2 036 Holstein x Zebu cows were evaluated monthly. This research took place between 2008 and 2014, within a five-year pe-riod as minimum, in the three kinds of dairy facilities (Basic Unit of Cooperative Production, Basic State Farm, and a farm). The variables used were births, total milk production, average milk liter/cow/day, and milking cows, which were decomposed according to season using a multiplication model. Seasonal behavior was observed in all the variables without a defined general pattern present in the total dairy production, and milk liter per cow/day (peaks from June to October), which coincided with the beginning of the pasture production peaks. Total milk production and milk liter average per cow/day are elements that can help set up the best moment to increase calving.
