美国农业部农业研究局(USDAARS)的一位科学家介绍,改进牧草的可消化性较其产量的增加更有利于牛肉生产者。据植物遗传学家Kennth P.Vogel报道,新育成一个柳枝稷品种——“Trailbl-azer”,其消化率提高6％,每英亩的牛肉产量增加23％。以1986年的价格计算,相当于使牛肉生产者每英亩增加35美元的利益。 Vogel说:“差不多只要可消化性稍加改变就会使家畜的生产性能得到很大改进,并且我们已证明改善其可消化性并不降低牧 A scientist at the U.S. Department of Agriculture’s Agricultural Research Service (USDAARS) introduced that improving pastiche digestibility is more beneficial to beef producers than its production. According to plant geneticist Kennth P. Vogel, a new switchgrass, Trailbl-azer, has a 6% increase in digestibility and a 23% increase in beef production per acre. At 1986 prices, the equivalent of an increase of $ 35 per acre for beef producers. Vogel said: "Almost as long as digestibility is slightly altered, the performance of livestock will be greatly improved, and we have demonstrated that improving their digestibility does not diminish
