Hyperlipidaemia in trypanosomiasis of naturally infected horses: possible cachexia–anorexia syndrome?

Trypanosomiasis caused by Trypanosoma evansi commonly produces wasting disease with signs of emaciation and cachexia mainly at the end stage. The present study was conducted to explore the possible hyperlipaemia or hyperlipidaemia and its association with cachexia–anorexia in equine trypanosomiasis. Out of the fifteen confirmed animals, none of the plasma sample was opaque. There was a significant increase in plasma triglyceride, total cholesterol and blood urea nitrogen and a highly significant increase in low-density lipoprotein (LDL) levels. A mild increase in high-density lipoprotein (HDL) and very low-density lipoprotein levels were observed, while the relative percentage of HDL and LDL was altered with high significance. A moderate increase in triglyceride and highly significant increase in LDL might be the reasons for retention of appetite and lipolysis. Possible protein breakdown and presence of lipolysis might be the reasons for cachexia in equine trypanosomiasis.  相似文献   

Antimicrobial activity of Andrographis paniculata   总被引：2，自引：0，他引：2  

Singha PK  Roy S  Dey S 《Fitoterapia》2003,74(7-8):692-694

The antimicrobial activity of aqueous extract, andrographolides and arabinogalactan proteins from Andrographis paniculata were evaluated. The aqueous extract showed significant antimicrobial activity, which may be due to the combined effect of the isolated arabinogalactan proteins and andrographolides.  相似文献

RELEVANCE OF A RAPID APPRAISAL APPROACH TO IDENTIFY LOCALLY AVAILABLE FEED INGREDIENTS TO SMALL-SCALE NILE TILAPIA (Oreochromis niloticus L.) AQUACULTURE     

M. A. Kabir Chowdhury  Dominique P. Bureau  Manik L. Bose  Madan Dey 《Aquaculture Economics & Management (Blackwell Science)》2013,17(2):151-169

Applications of a rapid appraisal approach to identify locally available feed ingredients in feed formulation, production, and socio-economics of Nile tilapia aquaculture in Bangladesh are discussed. Three diets of 35%, 30%, and 25% crude protein were formulated using locally available ingredients, and their essential amino acid profiles were assessed for Nile tilapia. Six production scenarios were constructed using these diets and two culture periods of 100 and 150 days were considered. The production scenarios with 35% protein yielded the highest productivity and profitability over the 150-day culture period followed by the 30% protein scenario. Identification of locally available ingredients and their application in small-scale Nile tilapia aquaculture may lead to: (1) increased availability of inexpensive sources of fish production for poor people; (2) increased fish consumption; (3) increased self employment and involvement of women in productive activities; and (4) increased household income to reduce poverty.  相似文献   

DEMAND FOR FISH IN THE PHILIPPINES: A DISAGGREGATED ANALYSIS

ABSTRACT

This paper sought to establish the fish consumption pattern of Filipino households and estimate the price and income elasticities of fish demand by species, as well as by income groups, i.e., low, middle, and high income. The study used the countrywide Family Income and Expenditure Survey (FIES) for year 2000 of the National Statistics Office, which includes over 39,000 households. A three-stage budgeting framework was used in the analysis, which estimated food and fish expenditure functions in the first and second stages, respectively. In the third stage, a system of demand equations for fish by species was estimated using a quadratic almost ideal demand system (QUAIDS) model. Parameter estimates of the model were corrected through the Heckman procedure to remove the possible bias brought about by zero consumption of certain fish species resulting from nonpreference or infrequent purchases. Results showed that estimated price and income elasticities of demand varied substantially across fish type and across income groups. All 11 fish types included in the study were found to have positive income elasticity for all income levels. Hence, fish in general can be considered normal goods, including processed fish. However, the high-priced fish types generated elasticity values greater than one, which rendered them as luxury food fish. Own-price elasticity, on the other hand, was found to be elastic in most species with values increasing as consumers climbed up the income ladder. This observation, however, was not true in the case of milkfish and tilapia (two most popular species in the country) where price responsiveness of demand was found to be higher among the lower-income groups.  相似文献   

Consumer Preferences for Live Seafood in the Northeastern Region of USA: Results from Asian Ethnic Fish Market Survey     

Ganesh Thapa  Madan M. Dey  Carole Engle 《Aquaculture Economics & Management (Blackwell Science)》2013,17(2):210-225

Asian ethnic fish markets in the Northeastern region of the United States of America (USA) are popular for selling live fish and seafood. A consumer survey was conducted in selected supermarkets of New York, New Jersey, and Pennsylvania during the summer of 2009 to assess consumer preferences for live seafood species. A binary logit model was developed to study the factors influencing preferences for live and fresh fish products. Results indicated that consumer preferences for live fish species vary by ethnic group. Live fish customers visited supermarkets at least two to three times a week and spent $16 to $20 a week to purchase medium size fish (0 to .91 kg live fish, on average). Freshness and appearance (bright, free of bruises, healthy fish) were the most important attributes. Findings indicate that promotion of live fish sales should be targeted to those stores dominated by East Asian (Chinese, Korean, and Japanese) customers.  相似文献   

Mathematical Model of Channel Catfish Foodfish Production in Multiple-Batch     

Umesh Bastola  Madan M. Dey  Lin Xie 《Aquaculture Economics & Management (Blackwell Science)》2013,17(4):353-371

Market size requirements for catfish change periodically, and catfish farmers must adjust quickly. Data from catfish pond studies at the University of Arkansas at Pine Bluff (UAPB) were used to develop mathematical models of catfish foodfish in multiple-batch culture across a variety of management alternatives. Two different functional forms (Cobb–Douglas and a modified translog) were each developed into average and stochastic frontier models. Inefficiency terms were found to be non-significant in the frontier models, thus making the average and frontier models equivalent. In the average regression models, the modified translog form demonstrated superior statistical values as compared to the Cobb–Douglas form, but the latter resulted in lower prediction error and was validated with the Chow test when used to predict observations from commercial catfish farms. This approach appears to have merit from the perspective of its statistical properties, and represents a step towards development of a model that could be used for farm management purposes.  相似文献
