Abstract

Abstract:

【Objective】 The purpose of this survey was to study the zinc (Zn) contents in various feed ingredients from different provinces and the basal diets of pigs and chickens in China, so as to provide a scientific basis for the reasonable addition of Zn in the livestock and poultry’s diets. 【Method】 A total of 37 kinds of 3 919 feed samples from 31 provinces, municipalities and regions were digested by microwave, and then the Zn contents were measured by IRIS IntrepidⅡplasma 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 Zn contents of these 37 kinds of feed ingredients ranged from 5.5 to 268.2 mg·kg ^-1, and the distribution of Zn contents in different species of feed ingredients was as follows: mineral ingredients (107.8 mg·kg ^-1)＞animal protein ingredients (69.8 mg·kg ^-1)＞plant protein ingredients (54.9 mg·kg ^-1)＞cereal by-products (43.0 mg·kg ^-1)＞pasture ingredients (26.4 mg·kg ^-1)＞cereals (22.7 mg·kg ^-1)＞straw ingredients (18.8 mg·kg ^-1). Among the same kind of feed samples, there were significant differences (P＜0.05) in the Zn contents from other six types of feed ingredients except pasture ingredients. In the mineral ingredients, the highest and lowest Zn contents were observed in the dicalcium phosphate (268.2 mg·kg ^-1) and limestone (7.3 mg·kg ^-1), respectively; in the animal protein ingredients, the highest and lowest Zn contents were observed in the hydrolyzed feather meal (120.8 mg·kg ^-1) and dried blood cells (19.6 mg·kg ^-1), respectively; in the plant protein ingredients, the highest and lowest Zn contents were observed in the linseed meal (85.2 mg·kg ^-1) and extruded soybean (38.9 mg·kg ^-1), respectively; in the cereal by-products, the highest and lowest Zn contents were observed in the wheat bran (86.2 mg·kg ^-1) and broken rice (12.5 mg·kg ^-1), respectively; in the cereals, the highest and lowest Zn contents were observed in the wheat (30.4 mg·kg ^-1) and corn (16.9 mg·kg ^-1), respectively; in the straw ingredients, the highest and lowest Zn contents were observed in the rice straw (27.6 mg·kg ^-1) and wheat straw (5.5 mg·kg ^-1), respectively. Regional comparison of Zn contents on a basis of provinces (regions) were made for Zn contents of corn, wheat and soybean meal, showing a significant effect (P＜0.05) of regional environments on Zn contents of the same ingredient. The highest and lowest Zn contents of corn were observed in Guangdong (20.6 mg·kg ^-1) and Jilin (13.7 mg·kg ^-1) provinces, respectively; the highest and lowest Zn contents of wheat were observed in Sichuan (41.4 mg·kg ^-1) and Gansu (22.4 mg·kg ^-1) provinces, respectively; the highest and lowest Zn contents of soybean meal were observed in Shanxi (51.5 mg·kg ^-1) and Jiangsu (46.6 mg·kg ^-1) provinces, respectively. Calculated Zn contents in basal diets from 142 common formulations of pigs and chickens in our country ranged from 21.3 to 31.0 mg·kg ^-1. According to Zn requirements of pigs and chicks from feeding standards of China and NRC of United States, the Zn contents in the basal diets could provide about one-fourth and one-second of the recommended Zn requirements for pigs and chickens in growing and finishing phase, respectively. 【Conclusion】 Results showed that the Zn contents in feed ingredients varied greatly among different kinds and regions, and the Zn contents in basal diets from common formulations of pigs and chickens could partly meet the nutrient requirements of pigs and chickens. Therefore, the Zn contents in basal diets from different regions should be considered in the preparation of diets, so as to meet the need of efficient production of livestock and poultry and to reduce supplemental Zn level and environmental pollution caused by Zn emission.
