Comparison of productive performance in dairy goats with and without serological evidence of Mycobacterium avium subsp. paratuberculosis infection

| Sumario: | Goat paratuberculosis (PTBC), caused by Mycobacterium avium subsp. paratuberculosis (Map), leads to production losses in clinical cases, but the effects of subclinical infection remain unclear. The aim of this work was to explore the effect of subclinical PTBC (infection on milk production and milk composition in Saanen goats in Argentina. Eighteen lactating multiparous Saanen goats calved during September were selected for the study. They were grouped on the basis of ELISAi, ZN and Map culture results in: Negative group (n=8) and Positive group (n=10). Milk production was individually recorded throughout the trial, and milk chemical composition was measured from samples collected 4 times during evening milking. Map infection was detected by isolation (from feces, milk or both) in 75% from the positive group of goats. Milk production resulted similar (p > 0.05) between negative (927.34 mL/goat) and Map serologically positive group (778.9 mL/goat). No significant differences were observed in milk composition or production between groups, indicating no detectable effect of subclinical Map infection in goats. |
