您所在州每英亩可饲养多少头奶牛?

如果您要养牛,您需要知道在您所在的州,每英亩地可以饲养多少头牛。 在不破坏土壤的情况下可以饲养的牛的数量因州而异,因此您需要根据动物单位的数量、放牧季节的长短和放养率进行计算。

计算每英亩有多少头奶牛

有一个简单的计算方法可以帮助您计算出奶牛需要多少土地。

所需牧场面积 = (牲畜单位数 x 放牧季节长度)/放牧率。

如果听起来很复杂,别担心,我们会一起解决的。

动物单位

一头 1000 磅的奶牛为一个动物单位(AU),因此一头 1400 磅的奶牛为 1.4 AU,一头 3500 磅的奶牛为 3.5 AU。

让我们以不那么吓人的 1400 磅奶牛为例!

放牧季节长度

放牧季节长度是指您希望奶牛在一年中放牧多长时间。 如果您在一年中的某些月份让奶牛在牛舍里吃干饲料,则不需要包括这些月份。

假设您想每年放牧 6 个月。

放养率

例如,在得克萨斯州西部,每个 AU 需要的本地牧草至少是得克萨斯州东部的 6 倍。

放养率也会根据气候条件逐年变化。 如果您所在地区遭遇干旱,放养率就会降低。

举例来说,每英亩放养量为 2.0 AU。 因此,根据这个例子,您可以计算出:(1.4 AU x 6 个月)/放养量 2 = 4.2 英亩)。

或者更简单地说: (1.4 x 6) / 2 = 4.2

这意味着我的农场每头奶牛需要 4.2 英亩的土地。

每亩地饲养更多奶牛

如果您想保持土壤质量,每英亩就不能饲养太多奶牛,但您可以通过轮换饲养不同的牲畜,最大限度地利用每英亩土地。

例如,您可以在牛群被赶走后让鸡在田里跑来跑去。 它们在土壤里抓来抓去,帮助土壤为新的生长做好准备。 它们还能加速牛粪的分解,滋养土壤,它们还能吃掉很多可能会困扰您的牛的寄生虫。

您还可以减少奶牛的放牧季节,让它们在一年中更多的月份里吃干饲料。 从长远来看,这可能会让您在饲料账单上损失与减少奶牛数量同样多的钱。

一个是六个,另一个是半打!

为什么要计算每英亩有多少头奶牛?

过度放牧是牧民常犯的错误,它会导致牧场生物多样性减少,从而助长外来和非本地植物和牧草的侵占,使牧草质量下降。

过度放牧还会造成土壤退化,而土壤退化是很难逆转的。 这不仅会增加今后的种植难度,还会造成土地沙化。 如果您过度放牧租给您的土地,可能会导致合同终止,如果土壤长期受到破坏,甚至会引起法律问题。

防止过度放牧

如果您的牲畜数量多到无法在原地持续放牧,您就需要将它们轮换到不同的牧场。 重要的是要让牲畜在不同的放牧区循环放牧,让牧场有足够的时间恢复,然后再重新开放放牧。

请记住,在干旱期间,牧场需要更长的时间来恢复。通常情况下,放牧后的 25 至 30 天足以让牧场休息。

改善过度放牧后的土壤

如果您担心草场过度放牧,可以使用绿肥(也称为覆盖作物)帮助恢复土壤和植被。 覆盖作物包括荞麦、三叶草和黑麦。

种植覆盖作物可以保护土壤,防止风和水造成土壤退化,并防止入侵杂草失控。

选择好覆盖作物后,只需将种子播撒到退化的草地上即可。 这样就有望淘汰入侵物种,并在土壤中固氮,同时让土地得到一年急需的休养生息。 您还可以选择种植牛能吃的覆盖作物。

如果可能的话,我们建议您在土地休耕期间不要让牛群进入,让覆盖作物腐烂回土壤中,使其恢复生机。 根据土壤退化的严重程度,您可以选择在几年内种植一系列覆盖作物。

我们希望这篇文章能帮助您解决一些问题!计算是一个很好的开始,但随着您信心的增强,放牧会变得更加直观,不再那么科学。

请记住:呵护您的土壤,土壤也会呵护您!如果您还有其他问题需要我们回答,请告诉我们,我们将竭尽所能提供帮助!
