One of the production breeds, ISA browns, Sex-links, production Reds (most RIR sold by hatcheries are production reds). Studies have shown that in hot weather an increase in foods high in antioxidants helps increase egg production.
It is concluded that vitamin E (125 IU/kg) and vitamin C (200 mg/kg) could independently alleviate the effects of heat stress on production performance and immunological variables of layers.
I know 1 KG= 2.2LBS and can work out the milligrams, but don't know IU/KG. Also in what form are the vitamins presented?
Sorry I'm not trying to highjack this thread.
IU/KG means International Unit per Kg. IU is how vitamins are measured.
For measuring Vitamin E, one IU = 1 mg
It's different for all vitamins, in that one IU of Vit. C isn't the same as one IU of Vit. D. You can buy vitamin tablets at walmart for humans, and break them up as needed to feed the birds. Or you can probably find some bird vitamin supplements for their water to you don't have to individually administer pills. Red cell for horses, is also a good supplement with lots of...well...everything in it. We give it to our chickens and pigeons at a tablespoon per gallon, once or twice a week.
