仔豬補鐵注射效果不好的原因
The cause of poor pig iron injection
鐵元素不足的仔豬容易出現缺鐵性貧血癥。但是部分給仔豬注射補鐵的養豬戶可能會發現效果不怎么好，出現這個問題，極有可能是以下原因引起的:
Iron deficient anemia is prone to iron deficiency anemia. However, some pig farmers who have been given iron supplementation to piglets may find that the effect is not very good. This problem is most likely caused by the following reasons:
1、注射日齡和部位
1, day and site of injection
過早和過晚補鐵都不行。過早注射與操作對出生小豬有強烈的刺激，會對身體系統造成沖擊。過晚則不能與自身儲備的銜接不上，易出現缺鐵癥狀。所以建議在3日齡注射為宜，一般可以選擇頸部或大腿內側肌肉注射，個人認為大腿內側較好。
It's not good to make up the iron too early and too late. Early injection and operation have strong stimulation to the born piglets, which will cause an impact on the body system. Too late can not be linked to their own reserves, easy to appear iron deficiency symptoms. Therefore, it is recommended that the injection should be done at 3 days of age. Generally, intramuscular injection of the neck or thigh can be done.
2、注射劑量
2. Injection dose
注射量應根據鐵制劑含量和豬只大小來決定，且不可千篇一律，個頭大的豬只多一點，弱小仔豬少一點。新生仔豬補鐵劑量掌握在150～200mg，量小不能滿足機體需求，量大則易產生較強的毒副作用。
The amount of injections should be determined according to the iron content and the size of pigs. The dosage of iron supplementation for newborn piglets is between 150 and 200mg, and the amount of iron can not meet the needs of the body.
3、泄漏問題
3. Leakage problem
一般頸部肌肉注射遺漏較多，為了防止泄漏，可用拇指拉緊注射部位的皮膚，方向為垂直于肌肉方向。在拔出針頭后，放開皮膚。這樣皮膚和肌肉上的小孔不在一條直線上，就會形成一個封閉。
Generally, there are more omissions in neck muscle injection. In order to prevent leakage, thumb can be used to tighten the skin of the injection site, and the direction is perpendicular to the muscle direction. After pulling out the needle, let go of the skin. So the pores in the skin and muscles are not in a straight line, and they form a closed.
