Veterinary researchers at Florida State University in the United States, using pigs as experimental subjects, will be fed with special treatment, making it a lack of zinc conditions. as a result, this treatment group may make the retina of pigs become chronic damage. it may be related. Veterinary ophthalmologists have completed monitoring changes in blood, skin, weight and major organs of young and older pigs. This pig eye, it is very similar to the structure of human eyes. This team of researchers has been able to identify the relevance of those changes.

Dr. DonASamuleson, a professor of eyeball anatomy, said that the treatment group containing 25% to 50% of the recommended amount of zinc in the feed could show the most dramatic changes in the eyes and liver. when the feed was chronically deficient in zinc supply for as long as a year, we could find changes in the eyes many times, as well as pathological changes in other major organs, including liver, skin, pancreas, esophagus and bones.

It causes human blindness that seems to exceed that of human eyes over the age of 70.

He explained that this zinc element seems to play an important role in the total amount of eye pigment. When the pigment becomes damaged in the case of lack of zinc, it affects the normal characteristics of the control light.

Dr. PatriciaJ.Smith, a veterinary ophthalmologist, is studying how the light interacts with zinc to affect pigment changes. It includes the retinal pigment epithelium and choroid pigment epithelium. He used 30 pigs for experiments to determine the effect of eyes on light intensity. He kept half of the pigs (15) in an artificially controlled light environment, so that there were 18 hours of artificial light and 6 hours of darkness every day. The other 15 pigs were taken 24 hours a day during the light period.

The results showed that the pigs in the 24-hour light treatment group could only confirm that there was more damage to the retina, and when there was too much zinc in the feed, the initial results may make the retina worse.

Mr. Samuelson and others have been studying whether there is enough zinc in feed since 1986. And to study the risks caused by too much or too little zinc. Therefore, according to the findings of this study, the authors have established the bottom line of zinc deficiency in sows during pregnancy, and established the standard requirements for zinc in the feed of piglets, middle pigs and pregnant sows.
