However, the average of kidding age was bigger between the reagents, when compared with not reagents, being statistically significant. The CAE did not influenced the reproductive aspects in this study on first kidding and on kidding interval.
The total production for lactation was 21.5% lower for positive goats.
The CAEv antibody-positive goats presented a mean daily milk yield (kg./day) lower than CAEv antibody-positive goats, with significant values for the groups: 12 to 24 months and 48 months or more. The average lactation length (in days) was lower for positive goats, significant values were found for goats of 24 to 36 months and for 36 to 48 months ones. The percentage of reagents to the CAEv rose significantly as the age grew. The frequency of occurrence of CAE, obtained for the three different moments of observation was 60,1%, 74,1%, 70,5%, respectively, and the total rate was 68.3% (566/829). Three serum tests were performed with intervals of 12 months. A goat herd coming from the contry of São Paulo state was evaluated for 24 months. The agar gel immunodiffusion test (AGID) was performed, using the following antigens from the CAEv: gp135, a glicoprotein and p28, an internal structural protein. The present study was carried out to compare the productive and reproductive aspects of Caprine Arthritis Encephalitis virus (CAEv) antibody-positive and antibody-negative dairy goats.
