In South Africa longevity is dependant on the range conditions. Very short grass results in more tooth wear due to greater sand ingestion. With longer grass many animals are still in use at 8-10 years.

Complete fleece shedding appears to be influenced by a number of factors. One may need to shear the top on mature sheep if you desire them to look their very best. See similar questions...

Their size is deceptive due to their short legs. Ewes will mature at 175-200 pounds and Rams over 225. These are practical sizes for a forage-based system. See similar questions...

The American Dorper Sheep Breeders Society was initiated in 1996 with a registry system. Two categories exist for White Dorpers and Dorpers. Those animals of 100% South African blood are full-bloods. Sheep that are a result of the grading-up program are American purebreds when ewes are 7/8 and rams15/16 pure. This is accomplished by using rams of your color selection on non-Dorper ewes and the resulting generations of increasing Dorper blood. See similar questions...

On intensive operations Dorper sheep need internal parasite monitoring and treatment like any other meat breed. There are possibilities that there are animal differences in susceptibility as you find in other sheep breeds. See similar questions...

Icelandics live to over 15 years old. Some shepherds stop breeding their ewes when they reach about 12. See similar questions...

Since sheep are a flock animal, they really do best with at least one other of their own kind. However, they also could be raised with goats with relatively few problems. See similar questions...

Well I guess that depends on who you talk to--Most farmers who are in the egg producing business will say 2 years. Those who are in the meat producing business will say 6 months--Those who keep birds as pets (with names) or who are not interested in maximum production of eggs, will find that chickens can live up to 8 or 10 years.

You'd think that would be a simple question, with a simple answer. Unfortunately, every source I've found gives different information: Britanica Online says the lifespan of a domestic cat in captivity is 21 years (in context, this seems to be the maximum age of the vast majority of otherwise healthy cats!!!). The Tidycat website once indicated that the average Russian Blue lives 18 years (I couldn't find a reference to persian lifespan). On the HomeArts Ask the Vet website, Dr. See similar questions...

The average life span of most giant breeds is about 8-10 years. I know of Danes living to 10-12 years, but right now unfortunately that is the exception rather than the rule. There are a few health problems which afflict the Great Dane breed: growth problems (HOD, PANO and OCD), hip dysplasia (OFA and Penn-Hip tests), and bloat/GDV/torsion are primary concerns. Wobblers, thyroid problems, and problems with the eyes (CERF test) also appear in the breed. Se our HEALTH links for more info: See similar questions...

Bees live for 6 weeks when gathering nectar during the summer. Their wings gradually wear away from constant activity. Those that are alive in the later fall live till spring and care for the larva hatched from eggs laid in late winter. These worker bees die before the honey flow starts again in the spring. The queen bee can live for 3-4 years. See similar questions...
