SUMMARY:

The objective of this work was to evaluate the processes of collection and manipulation of ejaculate in swine GTC with potential impact on sperm and microbiological quality of ID. Eleven boar studs distributed in the states of RS, SC, PR, MS and MT were evaluated, totaling about 1,650 boars in the total squad (around 25% of boars in the Brazilian squad in production). All units had the same computer semen analysis system (CASA; Magavision®Magapor®, Spain) in use for more than 12 months, calibrated to the supplier's standard. Quantitative and qualitative data from the semen production of the units were evaluated, based on two years of production, from August 2017 to July 2019, together with the sample evaluation of microbiology exams of the main critical points of production , DI sperm concentration and verification of the semen production process through a Check List with 75 evaluated items. The non-conforming items in the Check List of 96 visits were correlated in the period of 30 days before and after application, with the non-conforming results of the analyzes. In the evaluation of the contamination variables of pure semen, of the diluted and stored doses and in the water samples (input, post-treatment, stored and diluent), factors were found that showed significance (P<0.05), increasing the chance of damage occurring on the quality of the dose. In the concentration analysis, only the percentage of samples with a concentration >3.48 billion sperm in traditional doses was affected, with few non-standard samples for this variable. We identify the points in the process that negatively impact the quality of the dose and need to be considered according to the degree of risk.
