The titer of BLV-antibodies was estimated in the mammary gland secretion of 18 cows, naturally infected with BLV. Mammary gland secretion samples were collected every week since the 8th week ante partum and every day during the first week post partum. At the same time, blood samples were collected. The examination showed a marked decrease of antibody titer in the blood serum since the 5th week ante partum to the 2nd day post partum. Negative serological results were noticed temporary in the blood serum. The results indicate that serological examination of mammary gland secretion (dry secretion, colostrum) may be helpful because of high concentration of antibodies in the these secretions.
对18头自然感染牛白血病病毒（BLV）的奶牛的乳腺分泌物中的BLV抗体滴度进行了评估。自产前第8周起每周采集乳腺分泌物样本，产后第一周每天采集。同时采集血样。检查显示，从产前第5周到产后第2天，血清中的抗体滴度显著下降。血清中出现了短暂的阴性血清学结果。结果表明，由于这些分泌物中抗体浓度较高，对乳腺分泌物（干分泌物、初乳）进行血清学检查可能会有所帮助。
