Summary

Nine commercial dairy goat herds were studied for 24 weeks for SCC and mammary bacteriological status (including mycoplasma detection). The sanitary status of most of the herds was optimal and correct milking procedures were carried out. Samples for SCC were processed weekly. Bacteriological analysis of milk from udder halves was carried out monthly in eight herds (1-8), and after suspicion of infection (clinical cases of contagious agalactia-CA- or high increase of SCC). When mycoplasma species were isolated from non-clinically affected animals, the carrier goats were quickly removed. Infection by Mycoplasma agalactiae was detected in the five herds but only in one herd (No. 9) was the disease clinically evident, affecting most of the lactating goats, decreasing the milk production and increasing SCC up to 13xl0⁶ SC/ml. In contrast, the SCC for herds with mycoplasma but non-clinical CA did not increase and ranged from 601 to 1,191 (x 10³ cells/ml). The atypically “slow” occurrence of CA and measures implemented to control the disease are discussed.
