One hundred and two brackish water shrimp farms in Shyamnagar Upazila of Satkhira District, Bangladesh, were surveyed to study
their costs and returns. Key data were collected, using a questionnaire survey from January to August 2002. Profitability
of operations was affected by fluctuating yields and prices due to diseases, and generated economic risk. The average total
cost of production per hectare was 63,437.57 Bangladeshi taka (tk) (US$1,084.40/ha). The farmers achieved a variable yield
of black tiger shrimp (Penaeus monodon), ranging from 7.48 kg/ha to 455.03 kg/ha, with a mean yield of 146.39 kg/ha, through multi-stock and multi-harvest methods.
The gross and net incomes per hectare were tk49,999.87 (US$854.69) and tk40,307.04 (US$689.01), respectively. Of the total
biomass, 44% came from P. monodon, while the rest (23% and 33%) came from other shrimp and finfish respectively. The return to total cost of P. monodon was a negative profit (tk0.78). 相似文献

Changes in the levels of microsomal proteins, in the activity of microsomal aniline hydroxylase, and in the effectivity of Thiopental were studied in chickens given the Czechoslovak-produced type of polychlorinated biphenyls - Delor 103. The increased activity of aniline hydroxylase and the decrease of Thiopental sleeping time in chickens exposed to the action of Delor 103 indicate that this preparation is able to induce liver microsomal enzymes in doses as low as 5 mg per kg of feed. The induction of liver microsomal enzymes appears to be an important factor, able to exercise a direct influence on the biotransformation of various biologically important substances in the organism of chickens. 相似文献

This study investigated the prevalence of bacterial pathogens of the urinary tract in Australian cats. Urine was collected by cystocentesis and subjected to urinalysis, bacterial culture and susceptibility testing. A total of 126 isolates were obtained from 107 culture-positive cats. Escherichia coli was most commonly isolated (37.3% of isolates) with the majority of isolates showing susceptibility to the 14 antimicrobials tested. Just over a quarter of isolates (27.0%) were Enterococcus faecalis, which showed resistance to cephalosporins and clindamycin. Staphylococcus felis, a previously unreported feline urinary tract pathogen which was susceptible to all antimicrobial agents tested, comprised 19.8% of the isolates. S. felis was significantly associated with urine that had a higher specific gravity (p=0.011) and pH (p=0.006) and was more likely to contain crystals (p=0.002) than urine from which other bacterial species were isolated. This is the first published study that associates the isolation of S. felis with clinical signs of lower urinary tract disease in cats. 相似文献

BACKGROUND: Pradofloxacin is a 3rd generation veterinary fluoroquinolone designed to restrict the emergence of antimicrobial resistance during therapy. HYPOTHESIS: Pradofloxacin 2.5% oral suspension is a safe, efficacious, and palatable treatment for bacterial urinary tract infections (UTI) in cats. ANIMALS: Seventy-eight cats presented with lower urinary tract signs and were positive on bacterial culture of urine. METHODS: Cats were allocated into 3 treatment groups depending on bacterial susceptibility results: pradofloxacin (n = 27), doxycycline (n = 23), or amoxicillin-clavulanic acid (n = 28). All antimicrobials were presented in palatable liquid form. Posttreatment urine specimens were collected after completion of the course of treatment and submitted for bacterial culture and sensitivity. Owners were questioned before and after treatment about their experiences with administering oral medication to their cats. RESULTS: Posttreatment urine culture was negative in all cats in the pradofloxacin group, but there were 3 treatment failures in each of the other groups. Owners' perceptions of the difficulty of administering oral medication to their cats was more positive posttreatment than pretreatment (P = .001; P < .001). There was no difference in palatability among the treatment groups (P > .05). CONCLUSIONS AND CLINICAL IMPORTANCE: We conclude that pradofloxacin 2.5% oral suspension is a highly effective and safe antimicrobial treatment for bacterial lower urinary tract infection in cats, and that the palatable formulation optimizes owner compliance. These findings make pradofloxacin a useful addition to the veterinary formulary. 相似文献
