Bimolecular identification of M.ovinpeumoniae from nasal swab samples of sheep from various districts of Balochistan, Pakistan
Mycoplasma ovipneumoniae is an important respiratory pathogen of sheep across the world. In the present study nasal swab samples (n=778) were processed and 51isolates of M. ovipneumoniae were identified through biochemical tests and PCR. Difference in the isolation rate among districts (n=12), age groups (n=3), breads (n=6) was assessed. Similarly the isolate rate among healthy (n=513) and resp...

متن کاملImpacts of maximum sustainable yield policy to prey–predator systems
This article investigates the effects of reaching the maximum sustainable yield (MSY) in prey–predator systems where the prey population follows logistic law of growth. Two different models are proposed: (i) first model involves linear prey–predator interaction and intraspecific competition among predator populations, and (ii) the second one is a ratio-dependent prey–predator system. In the fir...
متن کاملImpact of maximum sustainable yield on competitive community.
A system of n competing logistical species of the Volterra type under proportional harvesting strategy is analyzed. In case of selective harvesting, when the effort is adjusted to each species, the optimum effort may result in the total maximum sustainable yield (TMSY(1)). When it exists, reaching TMSY(1) does not affect the system stability character, but it does affect the state, and hence so...
متن کاملMaximum Sustainable Yield Policy in Prey-Predator System-A Study
In this paper, maximum sustainable yield policy in prey-predator system is discussed where the prey population follows logistic law of growth. Here a model is proposed involving linear prey–predator interaction and intra-specific competition among predator populations. The growth rate of the predator depends upon predation on the modelled and alternate prey. In traditional prey–predator system,...
