铁的作(zuò)用(yòng)和缺失

Author:

作(zuò)用(yòng)：

铁对动物(wù)有(yǒu)多(duō)种功能(néng)。

血红蛋白中(zhōng)的铁, 对于维持机體(tǐ)每个器官和每种组织的正常生理(lǐ)作(zuò)用(yòng)是不可(kě)缺少的, 也在参与氧的运输、氧化酶( 如过氧化氢、过氧化酶、黄素蛋白酶) 和细胞色素中(zhōng)起重要作(zuò)用(yòng)。

缺失：

机體(tǐ)若贮铁或摄铁不足, 或因寄生虫感染失铁, 或红细胞分(fēn)解速度大于合成速度, 则出现缺铁性贫血

刚刚出生的小(xiǎo)猪為(wèi)什么要补铁

仔猪最容易缺铁。

刚出生仔猪＝47mg铁，但需7mg/天；

10－14天體(tǐ)重翻番，生長(cháng)速度快。

母猪奶中(zhōng)铁的浓度很(hěn)低, 约為(wèi)1 mg/ kg,

3日龄需补铁。(3日、12日龄补铁二次）

仔猪在出生后头3 d 一次注射150~200 mg 铁，比如桃源兽药厂生产(chǎn)的富铁力注射（1－1.33ml每次）。

Iron has many functions for animals.

The iron in hemoglobin, which is essential for the normal physiological function of every organ and tissue in the body, also plays an important role in the transport of oxygen, the enzymes ( hydrogen peroxide, peroxidase, flavin protease) and cytochrome.

Missing:

Iron deficiency anemia occurs if the body stores iron or takes insufficient iron, or loses iron due to parasitic infection, or the rate of red blood cell breakdown is greater than the rate of synthesis

Why should the newly born pig supplement iron

Piglets are the most vulnerable to iron deficiency.

Piglets at birth = 47mg iron, but need 7mg iron per day;

The body weight doubled in 10-14 days and the growth rate was fast.

Sow milk has a very low concentration of iron, about 1 mg/ kg,

3 days of age need iron supplement. (Iron supplement twice at 3 and 12 days of age)

Piglets are injected with 150-200 mg of iron at a time during the first 3 days after birth, such as the FuTieLi iron dextran injection produced by Taoyuan Veterinary Drugs Factory (1-1.33ml each time).
