中文摘要:
      调查我国畜禽饲料资源中钠含量的分布,为合理利用饲料资源及精准配制畜禽饲粮提供科学依据。对采自全国30个省 (市、区)的3 853个主要饲料原料样品中的钠含量进行测定,结果表明:不同类别饲料原料中平均ω(Na)(钠的质量分数)变化 范围为47.9~9 179 mg/kg。钠含量分布规律为:动物性蛋白饲料>矿物质饲料>牧草类>秸秆类>谷物加工副产品>植物性 蛋白饲料>谷物籽实。同一类别内不同饲料原料之间钠含量也存在显著或极显著差异(P<0.05或P<0.01)。以省(区)为单 位,对玉米、小麦、豆粕的钠含量进行地区间比较,发现饲料原料的钠含量受到地区环境变化的影响较大(P<0.05)。根据我国 各地猪、鸡常用的152个饲料配方所计算出的基础饲粮ω(Na)在71.5~271 mg/kg,远不能满足其正常营养需求,需要额外补 给。研究表明:饲料原料中钠含量受种类及地区性影响较大,以植物性饲料为主的猪、鸡基础饲粮中背景钠含量较低,不能满 足动物正常营养需求,需要额外补给。本调查结果对于生产者了解饲料原料中实际钠含量,精准配制饲粮,以确保动物的健康 及高效生产,降低饲料成本及减少钠元素排放对环境的污染等具有重要意义。
英文摘要:
      The distributions of sodium content in feedstuffs for livestock and poultry in China was studied to provide a scientific basis for rational use and precise formulation of feedstuffs. The determination results of sodium contents in 3 853 feed samples collected from 30 provinces (cities, regions) in China showed that the average sodium contents in different kinds of feeds ranged from 47.9 to 9 179 mg/kg. The distribution regularities of sodium contents were: animal-protein feeds > mineral feeds > forage feeds> straw feeds > cereal processing by-products > plant-protein feeds > cereals. A significant or extremely significant difference (P<0.05 or P<0.01) was also observed in sodium contents from different feeds in the same categories. Provincial comparisons in sodium contents of corn, wheat and soybean meal showed that the sodium contents in feed materials were greatly affected (P<0.05) by regional environmental changes. Among 152 common formulations of basal feeds for pigs and chickens in China, the calculated sodium contents ranged from 71.5 to 271 mg/kg, which could not meet the normal nutritional requirements, and additional sodium needed to be added to the feeds. In brief, results from this survey indicate that the sodium contents in feedstuffs in China were greatly affected by feed types and regions. The results would contribute greatly to producers' knowledge of actual sodium contents in feedstuffs to precisely formulate feeds to ensure animal health, efficient meat production, reduction of feed cost, and reduction of pollution on environment by sodium emission.
