摘要
冬、春羔实验系统连续５年（１９９０～１９９５）监测资料的平均结果表明，春羔系统（ＳＬＳ）的生产效率优于冬羔系统（ＷＬＳ），前者每公顷草地的产出数量为５９９个畜产品单位（ＡＰＵ）；后者为５８４个ＡＰＵ；前者每公顷草地的利润为６７２．３元，后者为５６８．４０元；投资利润率分别为３５％和３０％。基于系统监测资料的平均结果和已经达到的指标，对系统进行优化后，再将春羔系统与冬羔系统相比，则春羔系统的边际效益达５９０．９８元／ｈｍ２，利润为１１５９．３８元／ｈｍ２，比冬羔实验系统已获利润提高１．０４倍。
The results of five year(1990～1995)continuous monitoring winter and spring lambing systems undertraditional situations indicated that the efficiency of spring lambing system(SLS)superiors to the winterlambing system (WLS).The output of animal products and the profit were 599 Animal Products Unit(APU)/hm2 and 672.3 Yuan/hm2 for SLS,and 584 APU/hm2 and 568.4 Yuan/hm2 for WLS,respectively.Their percent return on capital was 35%and 30%,respectively.Within the improved systems the marginal change for SLS reached 590.96 Yuan/hm2,the surplus is1159.38 Yuan/hm2 which is 2.04 times of the gained surplus of WLS.
