- Abstract
Objective: To analyze the cost of the calving interval (CI) in cattle production in humid tropic of south-eastern Mexico and to predict the possible economic losses of farms in the humid tropics. Design/methodology/approach: Tropical farms corresponding to 1,200 cattle of the breeds: Simmental, Simbrha, Brahman and F1 crosses grazing, were analyzed. One-way ANOVA was used to compare costs among breeds. Linear regression was used to obtain the relationship between cow age and CI. Results: The cost of a day without pregnancy reached USD $0.99 (±0.05), and a cow that did not calve for one year represented an investment loss of USD $359.00 (±11.72) in relation to production costs. Limitations on study/implications: The income obtained from the sale of a calf at weaning and milk amounted to USD $734.10 (±16.98). Findings/conclusions: No significant differences were found between the races (p<0.05) and the CI, however, there was a positive relationship (r=0.9326, r²=0.8698, p<0.05) between the CI and the increase in the age of the cow.
