A barren cow is another name for an open cow or heifer. Barren cows are cows that are not pregnant.
An open or barren cow.
Yes. A barren cow (one that is open, or not pregnant) is able to come into heat or estrus.
A cow is considered barren if it does not become pregnant despite multiple mating attempts over an extended period. A veterinarian can confirm this through reproductive examinations such as ultrasound or blood hormone tests.
There are plenty of reasons you could be having a problem. The first set of reasons are "operator error" - did you inseminate 12 hours after observing a standing heat? Did you inseminate into the uterus, completely through the cervix? Did you keep the semen straws frozen properly until useage? The second set of reasons are "cow problems" - does the cow have a normal uterus? Does the cow ovulate, or is she developing cystic ovaries? Does the cow have fertile oocytes? Both sets of problems can be easily evaluated by your veterinarian - after 6 months, I would suggest paying the farm call fee and have him/her out.
A cull cow. She can also be called a free-loader, a barren cow, an old cow, etc., but cull cow is the best term to use because cows that can no longer have a calf is one that no longer needs to be a part of the more productive cow-herd.
a cow can produce 1,050 to 1,200 per week (121.8 to 146.3 gallons)
No. She is a dairy cow, one that is used to primarily produce milk.
A cow that has NEVER had a calf in her lifetime is called a Heifer. A cow that has not had a calf YET is a heavily pregnant or heavy-bred, or a short-bred or long-bred cow. A cow that has not had a calf during a calving season is called a barren cow, an open cow, a cystic cow, a cull cow, a meat/slaughter cow, a poor cow, a free-loader, etc.
A dairy cow will produce anywhere from 10 to 45 gallons of saliva per day.
