某公社有一家专业户想办一个机械化养鸡场。但他们不知道究竟应该办多大规模最好?在什么情况下设备、资金、劳力的利用率最高?每一只鸡的最低饲养成本是多少?最高利润是多少?能否保证达到队上的平均收入水平(1,548元/劳力·年)? 为了不蛮干,作到心中有数,他们到“经营咨询服务公司”请求“决策”咨询。经营咨询服务公司的会计师向他们询问了有关的情况和数据:他们有五个劳力,准备向银行贷款,租用生产队旧库房、马棚作养鸡场所(可容0.7—1万只鸡),计划订购一套可养0.6—1万只鸡的专用养鸡设备和载重汽车一辆,还同饲料公司签订了蛋鸡饲科供应合同,并准备以2,500元的年薪招聘一个技术员和一个汽车司机。根据机械化养鸡场的饲养方案,饲养蛋鸡的生产周期为四年,第二年产蛋250个,第三年产蛋280个,第四年产蛋220个。第四年底淘汰,每只淘汰鸡 A commune has a professional family who wants to run a mechanized chicken farm. But they don’t know how big the best they should be? Under what circumstances are equipment, capital, and labor utilisation the highest? What is the minimum cost of raising each bird? What is the maximum profit? Can it be guaranteed that the average team is reached? Income level (1,548 yuan/labour year)? In order not to be reckless, they were very aware that they went to the “operational consulting service company” to request “decision-making” consultation. The accountants of the operating consulting services company asked them about the situation and data: They had five labors, they were ready to lend to the bank, they rented the old warehouses of the production team, and the horse sheds were used as chicken farms (allowing 0.7 to 10,000 chickens). Plan to order a set of specialized chicken-raising equipment and trucks capable of raising 6,000-10,000 chickens, and also sign a feed contract for layer chickens with feed companies, and prepare to hire a technician and a car driver for an annual salary of 2,500 yuan. . According to the feeding plan for the mechanized chicken farm, the production cycle for laying hens is four years, 250 eggs are produced in the second year, 280 eggs are produced in the third year, and 220 eggs are produced in the fourth year. At the end of the fourth year, each chicken was eliminated.
