Cows can live to be 20 years old. Cows are considered"old" when they reach about 10 year old.

huh? It isn’t like there is a massive herd of wild cows and we are doing them a service by culling the herd. If we don’t need as many cows in the world, then we just won’t breed as many replacements, and we can put the land to other uses. 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...

Currently, we have 60 Holstein-Friesian and cross bred cows and calves, 30 of which are milking cows. The Holstein-Friesian breed is identified by black and white markings. In the Holstein breed each cow has unique markings distinct from any other cow . This breed is the most common in the United States due to their high milk production and large body frame. The average milking Holstein cow weighs 1,300 pounds. See similar questions...

No‚ the cows do not bite. In fact all the animals on the Farm are used to being cared for by school-aged kids‚ and therefore look at all children as their ‘friends’. See similar questions...

The most important part of their diet is the pasture grass they graze themselves all day (and, in the winter, high quality hay which we make ourselves on the farm). High quality forage produces the very best milk. Note that the pastures here are not fertilized with sludge or any chemical fertilizer. While being milked, the cows eat a little all natural grain supplement made from barley and oats (16% protein). They also receive mineral supplement free choice (available at all times).

In contrast to more typical dairy breeds, Jersey cows give a smaller amount of milk which is higher in butterfat. Our cows are giving about three gallons each, per day. Please note that milk production varies with the season, the weather, the quality of the forage available; and the normal curve of the cow's lactation cycle. See similar questions...

The cow sculptures are made of flame-retardant fiberglass and have within them steel rebar for reinforcement. The Cows weigh approximately 125 pounds before application by the artist.
