The OAU was, however, successful in some respects. Many of its members were members of the UN, too, and they stood together within the latter organisation to safeguard African interests â especially in respect of lingering colonialism. Its pursuit of African unity, therefore, was in some ways successful. Total unity was difficult to achieve, however, as the OAU was largely divided. The former French colonies, still dependent on France, had formed the Monrovia Group, and there was a further split between those that supported the United States and those that supported the USSR in the Cold War of ideologies.
How antlers grow. Deer grow and shed antlers annually. Males typically begin growing a new set of antlers in late spring. Growth starts at the pedicle, which is the antler growing base attached to the skull (see Figure 2).ntler growth of male fawns, or âbutton bucks,â is generally noticeable at 4 to 5 months of age by the presence of âbuttons.â At 1-1/2 years of age (yearlings), males grow their first noticeable antlers, which can range in size from spikes to 10 or more antler points.
At the same time, theyâre also growing a new set of antlers â a phenomenon unique among all other mammals. Itâs also a phenomenon that has made deer antlers prized as trophies for primitive and modern hunters alike. The antlers that are grown by male members of the deer family (and female caribou) are true bones. This is different from the unbranched horns of cows, goats and sheep that are composed of keratin, a protein similar to the hooves. While growing, antlers also have a blood and nerve supply.
