为了探讨规模化养殖场和养殖小区产奶牛生产水平及成本利润的动态变化,选择奶牛规模化养殖场和养殖小区各6个,在2,5,8月份分别测定产奶牛采食量和产奶量,计算成本和收益,进行效益的敏感性分析和动态分析。结果表明:规模化养殖场产奶牛干物质采食量、料奶比、产奶量、乳脂率均显著高于养殖小区(P≤0.05);产奶牛的收入和成本规模化养殖场虽都显著高于养殖小区,但效益也显著高于养殖小区。动态分析的临界点、牛奶价格、产奶量、采食量和饲料价格规模化养殖场均大于养殖小区。规模化养殖场效益的平衡点低于养殖小区。说明奶牛规模化养殖场的生产水平、收益和市场抗风险能力高于奶牛养殖小区。
In order to explore the dynamic changes of the production level and cost profit of large-scale dairy farms and farms, six dairy cattle farms and six breeding farms were selected. The feed intake and milk production of dairy cows were measured respectively in February, May and August Quantity, calculate costs and benefits, the sensitivity of the benefits of analysis and dynamic analysis. The results showed that the feed intake, feed conversion ratio, milk yield and milk fat percentage of dairy cow were all significantly higher than that of farmed plot (P≤0.05). The income and cost of producing dairy cattle were significant Higher than the breeding area, but the benefits are also significantly higher than farming area. The critical point of dynamic analysis, milk prices, milk production, feed intake and feed prices of large-scale farms are larger than farming district. The balance of benefit of large-scale farms is lower than that of breeding farms. Explain the scale of dairy cattle farms, income and market risk-resisting ability higher than dairy farming district.
