摘要:

目的 研究我国不同地区间各种饲料原料中锰含量分布情况,以及我国畜禽基础饲粮中锰水平,从而为饲粮中合理添加锰提供科学依据。方法 对采自全国31个省、直辖市和自治区的37种共3 922个主要畜禽饲料原料,经微波消解后,用IRIS Intrepid II等离子体发射光谱仪测定其锰含量。主要畜禽饲料原料可分为七大类,包括谷类籽实(玉米、小麦、稻谷及大麦)、谷物籽实加工副产品(碎米、次粉、小麦麸、米糠、玉米DDGS、小麦DDGS、玉米胚芽粕及玉米蛋白粉)、植物性蛋白饲料(膨化大豆、豆粕、菜籽粕、棉粕、花生粕、亚麻粕、葵花粕)、动物性蛋白饲料(鱼粉、肉粉、水解羽毛粉、肠系膜蛋白粉、血浆蛋白粉和血球蛋白粉)、秸秆类饲料(玉米秸、甘薯藤、稻秸和小麦秸)、牧草类饲料(羊草、黑麦草、苜蓿和青贮玉米)和矿物质饲料(石粉、磷酸氢钙、贝壳粉和骨粉)。结果 这37种饲料原料的平均锰含量范围为0.4—1 104.8 mg·kg -1,各类饲料原料锰含量分布规律是:矿物质饲料(335.4 mg·kg -1)>秸秆类饲料(180.8 mg·kg -1)>谷类籽实加工副产品(75.9 mg·kg -1)>牧草类饲料(53.3 mg·kg -1)>植物性蛋白饲料(44.5 mg·kg -1)>谷类籽实(38.7 mg·kg -1)>动物性蛋白饲料(19.6 mg·kg -1)。在同一类饲料中,不同种饲料的锰含量均存在显著差异(P<0.0003),其中谷类籽实饲料锰含量以稻谷最高(77.7 mg·kg -1),玉米最低(5.7 mg·kg -1);谷物籽实加工副产品锰含量以米糠最高(166.0 mg·kg -1),玉米蛋白粉最低(4.6 mg·kg -1);植物性蛋白饲料锰含量以菜籽粕最高(68.0 mg·kg -1),棉粕最低(27.0 mg·kg -1);动物性蛋白饲料锰含量以鱼粉最高(48.5 mg·kg -1),血球蛋白粉最低(0.4 mg·kg -1);秸秆类饲料锰含量以稻秸最高(458.1 mg·kg -1),小麦秸最低(37.8 mg·kg -1);牧草类饲料锰含量以羊草最高(89.1 mg·kg -1),苜蓿最低(33.0 mg·kg -1);矿物质饲料锰含量以磷酸氢钙最高(1 104.8 mg·kg -1),骨粉最低(16.9 mg·kg -1)。通过比较不同省(区)玉米、小麦和豆粕的锰含量发现,不同省(区)玉米及豆粕的锰含量存在显著差异(P<0.0004),其中贵州省玉米锰含量最高(7.9 mg·kg -1),而内蒙古自治区最低(4.2 mg·kg -1);浙江省豆粕锰含量最高(48.3 mg·kg -1),广东省最低(34.4 mg·kg -1)。根据全国各地猪、鸡常用的142个饲料配方所计算出的基础饲粮中锰含量范围为14.4—32.1 mg·kg -1,如按我国猪、鸡饲养标准或美国NRC锰营养需要量要求,基础饲粮中锰含量可提供鸡的锰营养需要约1/4,可提供猪全部锰营养需要,但上述估算尚未考虑不同饲料原料中锰的利用率。结论 不同种类和不同地区饲料原料中锰含量差异较大,全国各地常用配方中的基础饲粮中锰含量可提供鸡部分锰营养需要量及猪全部锰营养需要量。因此,在实际生产中,应充分考虑不同地区基础饲粮中的锰总含量及其利用率,精准配制饲粮,以满足畜禽高效生产需要,同时减少锰的添加和排放对环境的污染。

Abstract:

【Objective】 The purpose of this survey was to study the manganese (Mn) contents in various feed ingredients from different provinces (municipalities, regions) and the basal diets of pigs and chickens in China, so as to provide a scientific basis for the reasonable addition of Mn to the diets. 【Method】 A total of 37 kinds of 3 922 feed samples from 31 provinces, municipalities and regions were digested by microwave, and then the Mn contents were measured by IRIS IntrepidⅡ plasma emission spectrometer. The feed samples fall into seven types: cereals (corn, wheat, rice and barley), cereal by-products (broken rice, wheat middling, wheat bran, rice bran, corn DDGS, wheat DDGS, corn germ meal and corn gluten meal), plant protein ingredients (extruded soybean, soybean meal, rapeseed meal, cottonseed meal, peanut meal, linseed meal and sunflower seed meal), animal protein ingredients (fish meal, meat meal, hydrolyzed feather meal, dried porcine solubles, plasma protein powder and dried blood cells), straw ingredients (corn straw, sweet potato vine, rice straw and wheat straw), pasture ingredients (Leymus chinensis, ryegrass, alfalfa and corn silage) and mineral ingredients (limestone, dicalcium phosphate, oyster shell meal and bone meal). 【Result】 The results showed that the average Mn contents of these 37 kinds of feed ingredients ranged from 0.4 to 1 104.8 mg·kg -1, and the distribution regularities of Mn contents in different species of feed ingredients were as follows: mineral ingredients>straw ingredients>cereal by-productscpasture ingredients>plant protein ingredients>cereals>animal protein ingredients. Among the same kind of feed samples, there were significant differences (P<0.0003) in the Mn contents from all types of feed ingredients. In the cereals, the highest and lowest Mn contents were observed in the rice (77.7 mg·kg -1) and corn (5.7 mg·kg -1), respectively; in the cereal by-products, the highest and lowest Mn contents were observed in the rice bran (166.0 mg·kg -1) and corn gluten meal (4.6 mg·kg -1), respectively; in the plant protein ingredients, the highest and lowest Mn contents were observed in the rapeseed meal (68.0 mg·kg -1) and cottonseed meal (27.0 mg·kg -1), respectively; in the animal protein ingredients, the highest and lowest Mn contents were observed in the fish meal (48.5 mg·kg -1) and dried blood cells (0.4 mg·kg -1), respectively; in the straw ingredients, the highest and lowest Mn contents were observed in the rice straw (458.1 mg·kg -1) and wheat straw (37.8 mg·kg -1), respectively; in the pasture feeds, the highest and lowest Mn contents were observed in the Leymus chinensis (89.1 mg·kg -1) and alfalfa (33.0 mg·kg -1), respectively; in the mineral ingredients, the highest and lowest Mn contents were observed in the dicalcium phosphate (1 104.8 mg·kg -1) and bone meal (16.9 mg·kg -1), respectively. Regional comparisons on a basis of provinces (regions) were made of Mn contents of corn, wheat and soybean meal, showing significant effects (P<0.0004) of regional environments on Mn contents in corn and soybean meal. The highest and lowest Mn contents of corn were observed in Guizhou (7.9 mg·kg -1) and Inner Mongolia (4.2 mg·kg -1), respectively; the highest and lowest Mn contents of soybean meal were observed in Zhejiang province (48.3 mg·kg -1) and Guangdong province (34.4 mg·kg -1), respectively. Calculated Mn contents in basal diets from 142 common formulations of pigs and chickens in our country ranged from 14.4 to 32.1 mg·kg -1. According to Mn requirements of pigs and chickens from feeding standards of China and NRC of the United States, the Mn contents in the basal diets could provide about one-fourth and all the nutritional needs of recommended Mn requirements for pigs and chickens, respectively. 【Conclusion】 The above results showed that the Mn contents in feed ingredients varied greatly in different kinds and regions, and the Mn contents in basal diets from common formulations of pigs and chickens in our country could partly provide the nutritional requirements for chickens and the full needs of pigs. However, the bioavailabilities of Mn in different feed ingredients have not been considered in above evaluation. Therefore, the Mn contents in feed ingredients of different kinds and regions should be considered in the preparation of diets, so as to formulate the diets accurately and ensure efficient production of livestock and poultry and reduce supplemental Mn level and environmental pollution caused by Mn emission.
