| Abstract: | In this paper, energy flow, substance flow, along with transformed efficiency and economic benefits of energy and substance in Qionglai Boer goat farm's stockbreeding ecosystem are studied by a systemic analytical method of ecology. The results show: in this stockbreeding ecosystem, energy and coarse protein of exported by livestock and its product are respectively 31.07% and 31.77% of corresponding total amount, transformed efficiency of this two indexes amount to 16.56% and 17.81% respectively, rate of earning value of output is 36.42%, of which goat is up to 52.26%. This stockbreeding ecosystem is worth generalizing. |
