Twins.
Sure you dont complain when you get two heifers but more than likely they are one of each, and I hate them, the cow hardly ever picks up quite the same after twins. My uncle milks 110 cows, last (2004) year, he had 17 sets of twins with only two being twin heifers. Ive heard that it is something to do with the diet that causes twins to occur, is this true.Can the feed affect the embryo to split or make the cow to produce to eggs???

Re: Twins.
I have also heard the feeding program has something to do with it, but a lot of it is genetics. It is said that every other generation in a cow family should have twins. So if the genetics for twins are there it will continue.

Re: Twins.
We went right through the eighties with more than 10% twins every year, and even managed 2 sets of triplets (both sets all live and all same sex).
There would have been huge changes in the type of genetics used half way through that as we changed from friesian to holstein.
Feed would have been purely grass, grass silage and concentrates. Average yields back then would have been around 6500 litres.
Don't see those numbers today, but still get our fair share. Hate what it does to a cow, and the calves often take much more care as well.

Re: Twins.
15/16 years ago when we first purchased a Keenan and protein was the component that drove milk price, we pushed energy in the Autumn and got our herd protein up to 3.55/3.6. nine months later we were sick to death of sets of twins!!
It was part of our learning process, and not something that we ever tried again.
twins I guess, are partly due to a genetic tendancy, and partly due to nutrition.

Re: Twins.
the use of rBST in the muscle will also increase the Twin rate

Re: Twins.
I agree that bST seems to increase twins, but I have also seen several studies that show higher producing cows can throw more twins as well. Often wondered if it was the bST or the higher production.

Re: Twins.
We had a silly number of twins this summer (haven't counted how many, but much more than normal), all one of each kind. 
Wagon was introduced two years ago, cow condition is gradually building back up again, and fertility is improving. Have often wondered if there is a link between improved fertility and an extra egg.

Re: Twins.
Yes , This autumn is many twins . In my farm is from last 20 calving 4 twins and 1 triplets ! And triplets are heifer , all look good , mother too , sire Best from Manfred mother next bull is Tesk Terry .
Why twins ?
1. changing feed - for example - new corn silage
2. changing feeding system - for example new energy component.
3. changing weather - hot wheater changing coolish weather. Finish hot stress .
4. new medical care for your cows - for example fertility

Re: Twins.
In human genes I've heard friends say how the've had family memebers that are twins usually skipping a generation and the next generation delivering twins. In some cases this has happened over several generations.My family has never had any twins.
I've seen cow families that have simularities either skipping a generation or daughters over several laction poping out twins at some point in life.
But have also had times personally where several cows suddenly started having twins in a row and wonder If 9 months earlier something hadn't changed in the feed or water that makes them split by nature?

Re: Twins.
My father bought ten straws of United Nick just as he was becoming unavailable, and ended up with fifteen heifers. There was one set of twins, splitting straws two and three ways got the rest.
Better conception rate with the older type cow, no doubt, the rest was chance.

Re: Twins.
A bull's daughters may be geneticaly inclined to have twins, but the bull himself is not able to effect whether the cows he serves have twins or not.

Re: Twins.
broa- Now you know why Bush was elected US President instead of Kerry. Kerry was backed by those who want government to run every aspect of our lives, and invite other countries to tell them how. Better the devil you know, than the devil you don't know.
