一,加强饲养干奶期。怀孕到分娩母牛在75至90天开始停止牛奶,保证6070天的干燥期,在此期间,以保证孕牛吃35公斤和10公斤的混合饲料青饲料或青贮饲料每日子就这样在接下来的泌乳奶牛预留足够的营养。产犊照顾好以后 - 两头奶牛。产犊母牛,为了迅速做出后乳房水肿恢复正常,最好的挤奶,一天三次。该方法是每次挤奶产后约两公斤,不是所有的挤压的第一天;每隔一天哺乳占挤奶的三分之一;第三半;第四天都挤干净。同时,加强对乳房的热量和按摩,按摩和热敷每次挤奶要持续15分钟左右。三天之内产后饲喂优质干草,并逐渐增加精料和多汁饲料五天后,增加精料的数量在约1千克每天进行控制,直至整个乳房水肿消失,乳房胀痛,可以在饮食标准牛奶的生产需要。
三部戏的牛奶生产潜力。为了15天后,以最大限度地发挥奶牛,产犊的潜力,应该创造条件,千方百计保持最高的产奶量较长一段时间,所以高产稳产。如饲养标准提高1520%,超过3至5天,在乳持续升高,提高应增加1520%的标准,例如,直到乳不再上升。奶牛饲料应增加适口性好多汁饲料,如红薯,胡萝卜等。在正常情况下,前两至三个月的哺乳期是最合适的周期固定增加牛奶产量。
4,集中的饮食的比例不应过高。小集中,多营养,只能用来为绿色,厚,多汁饲料不足,以满足奶牛饲料添加剂时,对营养的需求。如果你只在乎浓缩饲料,粗饲料的忽视和多汁饲料,是由于过多的蛋白质磷酸化,从而使奶牛的身体呈酸性反应,造成早期奶牛失去生殖能力。但也容易导致消化不良等疾病,使产奶量和体力下降。
5指导喂养。初增加精子的数量,以容纳牛奶的需求产犊后。前2周为11.5%产犊母牛重量的浓缩物,得到后,产犊牛犊出品的3千克每1公斤的牛奶的细物料进料的比例。具体做什么,要注意牛的体况,防止过多的脂肪,而且还特别强调了粗饲料原料的质量和数量。根据该方法,大多数母牛可能出现较早峰哺乳期,奶产量增加了总泌乳。
6,诱发水。其方法是:薏仁粉,玉米粉,黄豆粉与水以1:10成糊状的比例,让牛饮用。在冬季,产奶量可提高10%左右,夏季和秋季,可以增加约12%。
七,几个挤奶奶牛提高产奶量。在45小时每次挤奶后奶牛,奶生产最旺盛的,当乳汁充盈池在一定程度上,牛奶会逐渐减少产生,所以及时,保证哺乳期的乳汁经常保持更高的速度。国内实践证明,改变两次,为期挤奶挤奶,提高产奶量11%,四次挤奶比增长6%挤奶了。一般高产奶牛,奶牛或在泌乳高峰期,而每天四次挤奶。在泌乳中期适量的牛奶或奶牛,挤奶,一天三次。或前任奶粉每天产奶量小于10kg的奶牛,每天挤奶两次。
8,按摩乳房。从怀孕开始的小母牛,按摩五个月,到15天前产犊停在每天上午,下午和晚上按摩1次,每次5分钟。这可通过10至15%的增加牛奶产量。从干奶牛产奶前10天之后开始按摩最初的5天,每天早上按摩1;第二个五天,每天早晚按摩一次;之后,每天早上,下午,晚上按摩1 30天10天交货之前停止按摩。这样可以提高约10%的奶产量。按摩,在5055℃的温水,先用毛巾蘸擦洗和按摩,然后按摩。
9,喂小苏打和胡萝卜素。从产犊前10天开始喂小苏打粉,牛奶已被送入日常喂量1.52%,可占饲养的罚款额的顶峰。每天饲喂7克-胡萝卜素,净增每哺乳期乳汁可能是130到150公斤牛奶前30天至90天产后奶牛的饮食。
十,饲养磷酸脲。磷酸脲是一种新型促生长剂的牛和其他反刍家畜,白色结晶性粉末,易溶于水,呈酸性。荷斯坦日常饲养磷酸脲每头日产奶量150克增加1.33千克,日增重和饲料转化率分别提高了10%和8%。
