Guar meal in diets for broiler chickens     

S. V. S. Verma  J. M. McNab 《British poultry science》1982,23(2):95-105

1. In two experiments each involving 2 000 Ross 1 broiler chickens in floor pens from 0 to 56 d of age, the effects of including guar meal at 50, 100 or 150 g/kg of the diet were investigated.

2. During the 0 to 28‐d period diets containing 50 or 100 g guar meal/kg supported only 85 and 69%, respectively, of the growth supported by the control diet, whereas during 28 to 56 d, birds fed on diets containing 100 or 150 g guar meal/kg gained 90 and 86% of the weight gained by control birds.

3. Neither toasting the meal, steam pelleting diets containing the meal nor supplementing these diets with 5 g methionine/kg had any appreciable effect on performance.

4. Addition of either of two enzyme preparations, MKC hemicellulase or betaganase M, improved growth; birds receiving 100 or 150 g guar meal/kg gaining 96 and 89%, respectively, of the weight gained by control birds from 28 to 56 d of age.  相似文献

High prevalence of antimicrobial resistance in Escherichia coli,Salmonella spp. and Staphylococcus aureus isolated from fish samples in India     

Vijay Veer Saharan  Preeti Verma  Arvind Pratap Singh 《Aquaculture Research》2020,51(3):1200-1210

Antibiotic resistance, driven by inappropriate use of antimicrobial agents for fish farming, is an expanding global health threat. Demand of animal protein for human consumption is entraining at remarkable pace which in turn, upturning the non‐judicial use of life‐saving drugs in these modern animal production practices at an incautious rate. Hence, study was devised to observe the antimicrobial resistance (AMR) pattern of human prominence bacteria, against drugs of critically and highly importance of both human and veterinary medicine, circulating over the fish farming in India. One hundred sixty fish faecal samples were obtained from distinct geographical locales of Rajasthan, India. Overall, 202 isolates comprising of Escherichia coli (81, 51%), Salmonella spp. (72, 45%) and Staphylococcus aureus (49, 31%) were isolated to screen for resistance. Antimicrobial resistance has been analysed using broth microdilution method. In case of E. coli and Salmonella spp., highest resistance (>95%) was observed against streptomycin while for S. aureus, it was observed against trimethoprim, along with high resistance to other antibiotics. Majority of the isolates were found to be resistant to more than three antibiotics implying multi‐drug resistance (>89%) relative to the critical and highly important antibiotics. The high AMR is a reflection of misuse of these agents in the fish farming, which is a concern of serious health issues. Our findings persuade the prudent use of antimicrobial agents in fish farming and other aquaculture settings that may assist in drafting of the new policies for the judicial use of these life‐saving drugs in these sectors.  相似文献   

Random amplified polymorphic DNA (RAPD) analysis of Mycobacterium tuberculosis strains in India     

J. P. N. Singh  Rishendra Verma  P. Chaudhuri 《Journal of veterinary science (Suw?n-si, Korea)》2006,7(2):181-187

The usefulness of random amplification of polymorphic DNA (RAPD) analysis for typing Indian strains of M. tuberculosis was investigated. M. tuberculosis H37Rv, M. tuberculosis DT and 42 clinical isolates of M. tuberculosis were subjected to RAPD-PCR using 7 random decamer primers. All 7 primers were found to be differentiated and produced specific RAPD profiles. The polymorphic amplicons served as RAPD markers for M. tuberculosis. The dendrograms, obtained by different primers, showed the discriminatory ability of the primers. RAPD analysis provided a rapid and easy means of identifying polymorphism in M. tuberculosis isolates, and it was found to be a valuable alternative epidemiological tool. In addition, the results of the present study showed heterogeneity in the M. tuberculosis strains in the population studied.  相似文献

Optimizing Koi Carp,Cyprinus carpio var. Koi (Linnaeus, 1758), Stocking Density and Nutrient Recycling With Spinach in an Aquaponic System     

T. Hussain  A. K. Verma  V. K. Tiwari  C. Prakash  G. Rathore  A. P. Shete  K. K. T. Nuwansi 《Journal of the World Aquaculture Society》2014,45(6):652-661

Fish waste water nutrient recycling in an aquaponic system was studied under different stocking densities of Koi Carp, Cyprinus carpio var. koi, along with spinach, Beta vulgaris var. bengalensis. Fish growth performance, plant growth, nutrient dynamics, and nutrient removal and their dependence on different stocking densities, namely 1.4, 2.1, and 2.8, were observed, of the different combinations, fish stocked at 1.4 kg/m³ had the best growth. Percent nutrient removal (NO₃–N, PO₄–P, and K) was significantly higher at 1.4 kg/m³. Thus, 1.4 kg/m³ stocking density can be suggested as optimum for Koi Carp production in spinach aquaponic systems.  相似文献
