Avian Mycoplasmosis is a chronic respiratory disease which causes very low mortality but it decreases egg production and causes carcass condemnation. A cross sectional study was conducted from September 2010 to October 2012 to identify the potential risk factors for Mycoplasma gallisepticum (Mg) seroprevalence in commercial chicken production in Chittagong area, Bangladesh. A total of 5589 serum samples were collected from one hundred chicken flocks of different production systems (commercial layer, broiler and layer breeder). Antibody against Mycoplasma gallisepticum was determined by commercial indirect Enzyme Linked Immunosorbent Assay (ELISA) kit. A multivariable logistic regression model was designed to evaluate the risk factors for Mg seroprevalence. The ELISA test results demonstrated that 32% of the birds were seropositive to Mg antibodies in the study area. A multivariable logistic regression model identified a strong effect of ‘age’ on the Mg antibody level where birds of more than 53 weeks of age showed the greatest risk of being positive for Mg (OR 419.27, 95% CI 294.67-596.54, P<0.0001) compared to birds less than 16 weeks of age. Moreover, monsoon season (OR 2.962, 95% CI 2.24-3.92, P<0.0001), male birds (OR 1.192, 95% CI 1.03-1.38, P=0.0196) and Commercial layer type of production system (OR 2.641, 95% CI 2.17-3.22, P<0.0001) were factors found to be associated the risk of attracting Mg in chickens. © 2015, Pakistan Agricultural Scientists Forum.

Buffalo Bulletin | Year: 2010
This field study was conducted to find out about the managemental conditions of the buffalo calf in Sheikhupura. The study revealed poor calf management. Diarrhea, heavy infection of both ecto and endo parasites, severe malnutrition were found in calves. It was also noticed that calves were not properly vaccinated and dewormed regularly. The veterinary treatment of the calves was found to be self medication or calling para-veterinary staff. The overall condition of buffalo calf rearing was found to be very pathetic and pointed to the need to educate the farmers and conduct extension work so the farmers get benefits from calves by rearing them in proper and scientific ways.

Purpose: To evaluate a 3% solution of household detergent viz., Surf Excel (Surf field mastitis test, SFMT) vis-à-vis California mastitis test (CMT), Whiteside test (WST), somatic cell counts (SCC; cut off limit = 5 × 105 cells per millilitre) and bacteriological cultures for the detection of subclinical mastitis in quarter foremilk samples (n = 800) of dairy cows and buffaloes. Methods: Culture and SCC were used as gold standards. All tests were evaluated parallel and serial patterns. The sensitivities of SFMT, SCC, culture, CMT and WST in parallel testing were 72.82, 81.55, 87.38, 75.73 and 54.37%, respectively in cows, while 66.22, 79.73, 82.43, 70.27 and 50.00, respectively in buffaloes. Results: SFMT was significantly (p < 0.05) more sensitive than WST and comparable to CMT in both species. In serial testing, percent specificity of SFMT (87.12 in cow; 85.16 in buffaloes) was significantly (P < 0.05) higher than that of CMT (83.33 in cow; 80.64 in buffaloes). The negative predictive values of SFMT (93.50 in cow; 96.35 in buffaloes) differed non-significantly from that of CMT (94.02 in cow; 96.15 in buffaloes). The kappa index between the tests was moderate to perfect both in parallel (0.54 to >0.80) and serial (0.58 to >0.8) testing. Conclusion: On the basis of closely similar diagnostic efficiency of SFMT to CMT in terms of sensitivity, specificity, predictive values and kappa index together with inexpensive and ready availability of SFMT reagent, it tempting to suggest that SFMT can be use as a cheaper, user-friendly alternative animal-side subclinical mastitis diagnostic test in poor countries. © 2009 Springer Science+Business Media B.V.

This study was conducted to investigate the outcome of organic acids on modulating liver and renal physiological functions in quail (Coturnix coturnix japonica). For this purpose, one group of 30 birds was offered potable drinking water, while other three groups, each of 30 birds were given 1, 2 and 3 ml of organic acid blend (citric acid 80g, lactic acid 52g, phosphorous 92g, copper sulphate 10g) per liter of drinking water, respectively for four weeks. Serum samples were used for estimation of liver and kidneys on weekly basis. Alanine aminotransaminase (ALT), aspartate aminotransaminase (AST), urea and creatinine showed significantly lower values in the treated groups compared to the untreated quails. The finding of the study suggested that addition of organic acids in the drinking water did not have any deleterious effects on health of liver and kidney in qauil.

The dromedary camel is a milk producing animal but its potential as a dairy animal has not been thoroughly evaluated. This study comprises 40 lactating camels of Kohi breed, selected from pastoral herds in northeastern Balochistan, Pakistan. Sampling was performed in 2006, every 15 th day during one lactation period (259±7 days). The daily milk yield ranged from 6.1-11.7 kg with a mean daily yield of 10.2±0.4 kg/day. Parity and age of the camels affected the milk yield. The highest milk yield 3168 kg was demonstrated in the 5th parity (13.5 years), followed by 3051 kg in the 3rd parity (8.8 years) and 3010 kg in the 4th parity (11.5 years). The lowest milk yield was 1566 kg produced in the 1st parity (4.5 years) (p<0.05). The study demonstrates the dairy potential of Kohi dromedary camels in traditional pastoral management.
