【摘要】：为分析草鱼疫苗接种的经济效益,依据选择成本原则,构建了草鱼疫苗接种成本-效益分析数学模型。应用该模型分析了华北某地草鱼免疫后的成本效益,结果显示,当地草鱼疫苗接种效益成本比为7∶1,使用疫苗后每公顷养殖水面增加净收入14500元,表明草鱼接种疫苗后可获得较大的经济收益。疫苗净效益随着疫病压力(未免疫鱼死亡率)增大、疫苗品质(免疫保护率)变好而升高,盈亏平衡分析表明,在其他条件不变的情况下,未免疫鱼死亡率1.8%,或者疫苗免疫保护率15.3%是草鱼疫苗接种的盈亏平衡点。敏感性分析表明,随着疫病压力的升高,疫苗免疫保护率对净效益的影响高于免疫成本。该模型可用于草鱼疫苗接种成本效益分析,为政府、企业、养殖户等选择疫苗提供科学依据。
[Abstract]:In order to analyze the economic benefit of grass carp vaccination, a mathematical model of cost-benefit analysis of grass carp vaccination was constructed according to the principle of selection cost. The results showed that the model was used to analyze the cost-effectiveness of grass carp vaccination in a place in North China. The ratio of benefit to cost of local grass carp vaccination is 7: 1. After using the vaccine, the net income per hectare of water raised by grass carp is increased by 14500 yuan. The results showed that the net benefit of the vaccine increased with the increase of disease stress (mortality rate of unimmunized fish) and the quality of vaccine (immune protection rate). The break-even analysis showed that the net benefit of the vaccine increased with the increase of disease stress (mortality rate of unimmunized fish) and the improvement of vaccine quality (immune protection rate). Under other conditions, the mortality rate of unimmunized fish is 1.8%, or the immunization protection rate of 15.3% is the break-even point of grass carp vaccination. This model can be used to analyze the cost-effectiveness of grass carp vaccination and provide scientific basis for the selection of vaccines by the government, enterprises and farmers.
