Abstract
Objective: To estimate the incidence of productive impact diseases in San Andrés Ixtlán, Gómez Farías county, Jalisco, México; through the monthly collection from clinical cases data, attended from January 2019 to January 2020, in seven smallholders dairy farms. Design/Methodology/Approach: Seven different smallholder livestock production units, mainly semi-stalled dairy cows, were monitored from January 2019 to January 2020, To calculate the frequency of the disease, the prevalence rate (PR) and the cumulative incidence rate (CIR) were determined, through the following equations: PR(Total cases in a population at a given place and time / Total population at that place and given time)10n and CIR(Number of new cases in period and place / Total population at the beginning of the period in that place)10n Results: According to 184 clinical cases, the metabolic diseases (21.20%) showed the highest PR, followed by parasitic (14.67%), bacterial (13.04%) and trauma (7.07%). For the CIR, diseases caused by gastrointestinal parasites (12%), showed the highest incidence, followed by mastitis (6%) and in third place malnutrition (5%). Gastrointestinal parasites of the genus Moniezia spp. (27.27%) and Trichuris spp. (4.55%) were found with higher and lower prevalence, respectively. Study Limitations/Implications: The lack of information from regional studies that describe the productive impact diseases faced by smallholders dairy farm in the different regions of the state of Jalisco. Findings/Conclusions: It is concluded that the most frequently problems are metabolic, followed by infestations by gastrointestinal parasites, especially those of the genus Moniezia spp.
