None. Calves don't suckle on any breast, they suckle on the udder (NOT "utter") of their mothers, being cows. Breasts are for baby humans, apes and bear cubs and possibly even elephants. But not calves.

Any time she's not pregnant already, since a cow is a mature female bovine that has already had calves before.

It is highly variable with heifers. A heifer can start to bag up anytime from two months prior to or right after calving.

When do calves start to ovulate?

Any time of the year: Winter, Spring, Summer or Fall. Most commonly calving occurs in mid-winter to early spring, or for most grass-fed cow-calf operations, mid-spring to early summer. It's not uncommon to have producers calving in the fall, either, but this tends to be more common in areas were cold winters and snow is not as much of a problem as it is in the Northern States like Montana and North Dakota, and the Canadian provinces.


How long can a heifer be in labor?

Heifers don't lactate prior to their first calf. However, they may start lactating several weeks before giving birth, but they aren't lactating like a mature cow does.


How many months between calving?

For one cow, it's usually 11 to 12 months in between each calving. For a cow-calf operation with defined breeding and calving seasons, it's always 12 months in between the start of one season to the start of the next.


How many cows are milked daily?

This question is impossible to answer because the number of cows per farm differs, as well as number of cows on farm per day, since cows that were milked one day wouldn't be milked the next or vice versa because either they'd be culled and sold, come down with a sickness, be of the time to be dried up before calving, or start giving milk as heifers or (for older cows) after calving, etc.


What age should you start putting your bulls with your heifers?

When the heifers are at least 14 months old, you can put yearling bulls (15-20 heifers per bull for yearlings) in with them. Don't put your big mature bulls in with your heifers as this could cause problems later on.

Hpow do you make yourself lactate?

You should start calving season by March 16.


How long should you wait to pull a calf after its foot appears?

Don't wait. This is a good time to put on the calving chains and start pulling. Make sure the cow is secured in a head gate first, though, before you latch on the calving chains on the calf.


When do you separate young cows and bulls?

I'm assuming that by "young cows" you are referring to heifers. You should separate heifers and bulls right after they're weaned, which is around 6 to 10 months of age, or before one or more of them are going to start puberty.


How do you neutralize the heat in green chilli?

Lactate containing foods such as yogurt, milk and cheese are heat mitigating agents for spicy ingredients.


How do you get a cramp?

Muscular cramp occurs when the oxygen demand by muscles is greater than what the body can provide. When the supply is less than the demand, the muscles start to undergo anaerobic respiration - this results in a build-up of lactate in the muscles. When the levels of lactate become too high, the muscles cramp.
