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.
At least 65% of this amount should be forage. In other words, a 1000 lb horse should be fed 18 lb of dry matter each day. Dry matter (DM) is the amount of feed that does not contain moisture; the DM content of hay is considerably higher than fresh grass.our hay analysis should show the DM content of your forage. If you are feeding 100% hay and your hay contains 90% DM (or 10% moisture), your 1000 lb horse should be fed 20 lb of hay (18 lb DM/0.9) straight from the bale each day.
