Add more ports by: Upgrading your Mac's graphics card. Apple has phased out this proprietary display plug, but you might see it on an older monitor or Mac. Look for the rounded shape of the rectangular connector to help in identification. The cable carries power, USB, and video. You can adapt a DVI signal for an ADC monitor, but the converter boxes can be pricey; an ADC signal from a Mac is more easily converted to DVI for a standard display.
Most nutrition articles about feeding horses recommend approximately two (2) percent of their body weight in forage per day. This would mean a 1,000-pound horse would need about 20 pounds a day. This amount is not carved in stone.
Adding a commercially fortified feed will offer some vitamin E to your horse s diet -- the average feed contains 150 IU or less per pound. Therefore to obtain the same 1100 IUs as from healthy pasture, you would need to feed more than 7 pounds of feed per day an amount too high for most horses.orses that graze on pasture usually get all the vitamin E they need. Fresh grass contains approximately 110 IUs of vitamin E per kg of dry matter. If your 1100 lb (500 kg) horse spends all day on a healthy field of grass, a generalized level of consumption would be 22 lbs (10 kg) of dry matter each day.
