【摘要】:為了探討規(guī);B(yǎng)殖場(chǎng)和養(yǎng)殖小區(qū)產(chǎn)奶牛生產(chǎn)水平及成本利潤(rùn)的動(dòng)態(tài)變化,選擇奶牛規(guī)模化養(yǎng)殖場(chǎng)和養(yǎng)殖小區(qū)各6個(gè),在2,5,8月份分別測(cè)定產(chǎn)奶牛采食量和產(chǎn)奶量,計(jì)算成本和收益,進(jìn)行效益的敏感性分析和動(dòng)態(tài)分析。結(jié)果表明:規(guī)模化養(yǎng)殖場(chǎng)產(chǎn)奶牛干物質(zhì)采食量、料奶比、產(chǎn)奶量、乳脂率均顯著高于養(yǎng)殖小區(qū)(P≤0.05);產(chǎn)奶牛的收入和成本規(guī)模化養(yǎng)殖場(chǎng)雖都顯著高于養(yǎng)殖小區(qū),但效益也顯著高于養(yǎng)殖小區(qū)。動(dòng)態(tài)分析的臨界點(diǎn)、牛奶價(jià)格、產(chǎn)奶量、采食量和飼料價(jià)格規(guī);B(yǎng)殖場(chǎng)均大于養(yǎng)殖小區(qū)。規(guī);B(yǎng)殖場(chǎng)效益的平衡點(diǎn)低于養(yǎng)殖小區(qū)。說(shuō)明奶牛規(guī);B(yǎng)殖場(chǎng)的生產(chǎn)水平、收益和市場(chǎng)抗風(fēng)險(xiǎn)能力高于奶牛養(yǎng)殖小區(qū)。
[Abstract]:In order to investigate the dynamic changes of production level and cost profit of dairy cows in large-scale farms and farming areas, six dairy cattle farms and six farming communities were selected to measure the feed intake and milk yield of dairy cows in August. Calculate the cost and benefit, carry on the sensitivity analysis and dynamic analysis of benefit. The results showed that the dry matter intake, feed / milk ratio, milk yield and milk fat rate of dairy cows in large-scale farms were significantly higher than those in farming areas (P 鈮,
