【文章內(nèi)容簡介】 L : 1 L milk or up to 170 L/day ? poor quality water can result in low intake and interference with mineral absorption 水分 ? 奶牛對水的需求量與產(chǎn)奶量的比例為 4： 1(升 )或一天的需求量為170升 ? 劣質(zhì)水減少家畜采食量并影響對礦物質(zhì)的吸收 限制家畜生產(chǎn)的營養(yǎng)物質(zhì) First Limiting Nutrient Minerals ? body contains large amounts of mineral elements ? at least 14 are considered essential ? divided into minerals needed in large amounts and those needed in very small amounts Calcium ? needed for tissue growth, bone development and reproduction ? shortage causes poor production and growth, stiffness, lameness, rickets and weak and stillborn calves 礦物質(zhì) ? 家畜體內(nèi)含有大量的礦質(zhì)元素 ? 至少有 14種礦質(zhì)元素是必要元素 ? 礦質(zhì)元素可分為大量元素和微量元素 鈣 ? 鈣是組織生長，骨骼發(fā)育和繁殖所需的元素 ? 缺乏鈣元素導(dǎo)致家畜減產(chǎn)，發(fā)育緩慢，引起僵腿病 , 跛腿病，軟骨病，所產(chǎn)小畜弱小，甚至產(chǎn)死胎 限制家畜生產(chǎn)的營養(yǎng)物質(zhì) First Limiting Nutrient Phosphorus ? for normal growth, reproduction, lactation and development of bones and teeth. ? important for rumen bacterial development and maintenance ? shortages cause reproductive failure, poor appetite and growth, stiffness and rickets ? roughage is low and grain medium levels ? ratio with calcium/phosphorous is critical, about :1 磷 ? 是奶牛正常生長、繁殖、產(chǎn)奶 、和骨骼牙齒發(fā)育所需的元素 ? 對家畜瘤胃細(xì)菌的發(fā)育起重要作用 ? 家畜缺乏磷元素導(dǎo)致繁育能力的喪失，食欲不振，生長緩慢，并引起 僵腿病和 軟骨病 ? 粗飼料含磷量較低，谷物含磷量中等 ? 鈣和磷的臨界比例應(yīng)為 ： 1 限制家畜生產(chǎn)的營養(yǎng)物質(zhì) First Limiting Nutrient IMAR Feed Test Results ? found 4 minerals to be deficient 1) phosphorous 2) copper 3) zinc 4) selenium 內(nèi)蒙古飼料化驗(yàn)分析結(jié)果 ? 缺乏 4種礦物質(zhì)元素 1) 磷 2) 銅 3) 鋅 4) 硒 限制家畜生產(chǎn)的營養(yǎng)物質(zhì) First Limiting nutrient Trace Minerals Cu ? operate systems through enzyme function ? shortage signs include: diarrhea, depressed estrous, puffy joints, reddish pigmentation in blacks ? antagonistic action by molybdenum and sulfur in soil and water 痕量元素 銅 ? 銅對家畜的作用通過酶來實(shí)現(xiàn) ? 家畜缺磷的特征為：腹瀉，發(fā)情推遲，關(guān)節(jié)腫大，色素沉著 ? 與水，土壤中的鉬和硫形成拮抗作用 限制家畜生產(chǎn)的營養(yǎng)物質(zhì)First Limiting nutrient Trace Minerals Zn ? involved in energy use, immune response system and normal development ? shortage signs include: listlessness, salivation, rough skin and hoof, poor healing, reduced production/ growth. Reduced feed intake and efficiency 痕量元素 鋅 ? 與家畜能量的利用，免疫反應(yīng)系統(tǒng)和生長發(fā)育有關(guān) ? 家畜缺鋅的癥狀為：精神不振，分沁唾液，皮膚和蹄子變粗糟，減產(chǎn)，生長緩慢，采食量減少，采食效率降低。 限制家畜生產(chǎn)的營養(yǎng)物質(zhì) First Limiting nutrient Trace Minerals Se ? Involved in strong immune response, and muscle metabolism ? shortage signs include: white muscle disease, stiffness, sore muscles, poor doing, weight loss, diarrhea and reduced immune response 痕量元素 硒 ? 與增強(qiáng)免疫反應(yīng)和提高肌肉新陳代謝有關(guān) ? 家畜缺硒的癥狀為：引起白肌病、僵腿病、腹瀉等疾病，減少體重，減弱免疫反應(yīng) 限制家畜生產(chǎn)的營養(yǎng)物質(zhì) First Limiting Nutrient Vitamins A E ? Vitamins A and E are often short ? Vitamin A, in green forage/yellow grain ? deteriorates over time(24 months)
