The Role of Zinc in Pig Health, Production and Reproduction

Nice academic work

In conclusion, how, and in what amount should one include the zn in form of Zinc oxide to the diets of Pigs generally for weaners; growers; sows & gilts; lactating pigs and Boars to avoid the issue of zinc deficiency? Anthony Tugbiyele

Dear KULAIT RFLINA ET FLA et al.! Someone once wrote that zinc is part of 200 enzymes, but apparently it seemed little and increased to 300. Who counted them? So now this figure will be rewritten from one review to another! Often write organic or inorganic zinc. This is not correct. A single element cannot be organic or non-organic. These properties are inherent only in complex substances. I do not recommend getting carried away with pharmacological doses of zinc, which are prohibited in the EU. It act mainly on the microflora, and the animal's body is protected from excessive intake of zinc. Zinc plays a huge role in regulating the formation of metallothioneins, which form the antioxidant cycle "thioneion-thionen". This cycle is more active than glutathione-peroxidase, but experts of animal feeding do not know much about it yet. Everything I have written has above nothing to do with the evaluation of Your article. You wrote a good review. A lot of knowledge related to the action of zinc has been systematized. Interesting facts are reflected. In the future, each fact can be addressed with the question: How? or Why? That is, to study the mechanisms of this or that phenomenon. Knowledge of the mechanisms will allow you to manage them. You are young and you have a lot of strength, but I am not an extinct dinosaur I wish you success
