A steeper decline in reproductive performance was found as they became 12 years of age. With sources such as PETA Rolling Stones the like you are probably concerned about this.

How old do cows live to be. A small decline was noted in 1983 as cows aged from 8 to 10 years of age. However the most consistent decline in reproductive performance was noted after cows were 10 years of age. A steeper decline in reproductive performance was found as they became 12 years of age.
By now you have most likely been informed that the average age of a dairy cow in the United States is 5 years old. That doesnt seem very old for a cow now does it. The average life of a dairy cow should be 15-20 years depending on your source.
With sources such as PETA Rolling Stones the like you are probably concerned about this. They make claims that cows are burnt out spent. Age at slaughter typically can be from 12 to 22 months of age for the high quality grade market.
The reason for the range in age is that some calves are weaned and go directly to a feeding facility and are finished for slaughter. Some calves are backgrounded grown on grass pastures then fed a high-energy diet for a short period of time 100 to 120 days and then slaughtered. Normally 36 months is the maximum age of a cow that you raise for slaughter.
It is because the profits you earn from over-36-month beef cattle will no longer be guaranteed. So which exactly the age of cows will be the most economical for slaughtering. Post by liveoak onMay 25 2011 at 147pm.
I am interested to know this also. I have heard of some beef cows living to late teensearly 20s but I dont know if there is any difference with dairy breeds. I would suspect that high producers could live shorter lives due to.
A six year old dairy cow if allowed to rest from milking will divert the energy used for milk production into fat storage and will develop a rich creamy marbling and delicious sweet flavor. Grass fed dairy cows do not require a grain finishing and are much higher in healthy omega-3 fats. Interesting Cow Facts The oldest cow ever recorded was a Dremon Cow named Big Bertha who died 3 months just before her 49th birthday on New.
Big Bertha also holds the record for lifetime breeding as she produced 39 calves. The heaviest live birth of a calf is 225 lbs for a British Friesian cow. Experienced breeders believe that the average life expectancy of cows is about 20-25 years.
Is this a lot or a little. The horse lives about 30 years the dog -15 the pig -20. Long-livers can be called geese.
They with good care can live up to 40 years. However this is not the norm and usually remain in the herd for 4 to 5 years. Many do not last nearly that long due to hoof problems structural problems fertility.
Cows can easily reach the age of 20 years or more but the longevity of animals is often artificially reduced by humans for breeding purposes. Practically there is no mathematical formula well at least not a simple one because the age of a cow does not follow a linear curve compared with the human age. Some lines of cattle perform better than others and maintain their ability to milk better.
However if pasture is short a cow more than 10 is old. Further review of the data shows 5- 6- 7- 8- and 9-year-old cows weaned 627 620 599 643 and 607 pounds of calf per cow respectively. Another notable Angus that was listed by Hugh Watson was Old Granny who was said to have lived to be 35 years of age and produced 29 calves.
Old Granny and Old Jock are two Angus cattle that most Angus cattle around today can trace their lineage back to. My husband mentioned that we had a few 15-year-old cows that we would likely cull this year. Our companions seemed shocked that we had several cows that old in our herd and said their oldest cows were just shy of a decade.
It got me thinking about the value of a cow in a cow-calf operation. How long should a cow stay in your herd. It has been reported that dairy cattle can live up to 20 years though this is more the exception than the rule.
