Abstract :The aim of this study was to determine the effectiveness of dry-off antibiotic therapy and teat sealant on somatic cell count insert ignore into journalissuearticles values(SCC); in Saanen goats. The goats were randomly divided into 3 groups. In Groups I insert ignore into journalissuearticles values(n = 50); and II insert ignore into journalissuearticles values(n = 50);, the goats were treated with intramammary antibiotics and a combination of intramammary antibiotics and internal teat sealant at dry-off, respectively. The animals in Group III insert ignore into journalissuearticles values(n = 50); were designated as the control group. For the SCC analysis and bacteriological examination, milk samples insert ignore into journalissuearticles values(n = 900); were collected separately from each udder half during routine morning milking, prior to drying off, and at months 1, 2, 3, 4, and 5 of following lactation. The pretreatment prevalence of intramammary infection at dry-off was 4.7% insert ignore into journalissuearticles values(7/150); for halves. Isolated pathogens were coagulase-negative staphylococci insert ignore into journalissuearticles values(57.1%); and S. Aureus insert ignore into journalissuearticles values(42.9%); from infected halves. Dry-off antibiotic and dry-off antibiotic with teat sealant therapy reduced milk SCC levels significantly insert ignore into journalissuearticles values(P < 0.01); when compared to the control group. On the other hand, the difference in SCC between dry-off antibiotic and dry-off antibiotic with teat sealant therapy groups was not statistically significant insert ignore into journalissuearticles values(P > 0.01);. In conclusion, intramammary antibiotics administered alone and a combination of intramammary antibiotics and teat sealant reduced milk SCC levels significantly.
