Evaluation of herbal coccidiostat ‘Coxynil’ in broiler

740-744Anticoccidial efficacy of "Coxynil" a polyherbal preparation was tested against Eimeria tenella in broilers. Body weight of birds challenged with E. tenella in Coxynil treated groups was higher as compared to Coxynil untreated. Oocyst out put, lesion score, HI titres against New Castle disease virus were significantly higher in Coxynil supplemented groups in comparison to Coxynil un-supplemented groups. Examination of ceaca of the birds, revealed that the Coxynil interfered with life cycle of coccidia. The typical second generation schizonts were absent in ceacal section of Coxynil treated groups. The results indicate that Coxynil is effective herbal coccidiostat

The prevalence of brucellosis among cattle from 11 farms having a history of abortions was studied. A total of 481 samples comprising of blood, milk, vaginal swabs, vaginal discharges, placental tissues and fetal tissues were collected from 296 animals. Clinical samples were processed for the isolation of Brucella. Serum samples (n = 296) were tested by Rose Bengal Plate Test (RBPT) and indirect ELISA. A total of 90 (30.40%) and 123 (41.55%) samples were positive by RBPT and indirect ELISA, respectively. Also 27.02% samples were positive by both the tests. Brucella isolates (n = 8) were recovered from clinical samples using Brucella selective media. All the isolates demonstrated PCR amplification for the bcsp31 and IS711 genes. Amplification of B. abortus specific primer was demonstrated by all the isolates in AMOS PCR indicating isolates to be of either B. abortus biotype 1, 2 or 4. Risk factors for transmission of brucellosis among cattle population were studied by field surveys. It was observed that lack of awareness about brucellosis (OR = 8.739, P = 0.138) and inadequate floor space (OR = 0.278, P = 0.128) were crucial risk factors for transmission of bovine brucellosis.Not Availabl
