How do you bring a cow into heat?
The standard treatment for cows with a corpus luteum (CL) is an injection of prostaglandin (PG) which will bring most cows into heat two to four days after injection.
Combining the PG with heat detection focussed on the treated cow will result in cows getting pregnant more quickly..
What sound do cows hate?
High pitched noises such as whistling are also unpleasant to cows. Intermittent sounds such as clanging of metal (e.g. gates), shouting and whistling can be particularly stressful, especially if they are sudden and at a loud volume.
Why are my cows not cycling?
This can be due to either True Anoestrus or Suboestrus. Suboestrus is when cows have normal cyclic ovarian activity, but are not detected in oestrus due to weak or silent heats, or due to inadequate observation. True anoestrus is when cows have inactive ovaries.
Can a pregnant cow show signs of heat?
Pregnant cows are sometimes bred by mistake either because of an aggressive heat detection or because some pregnant cows do show some signs of heat. A questionable heat is the result of a cow that was not seen standing to be mounted and/or is not showing enough secondary signs of heat.
How many times will a bull breed a cow in heat?

What is heat period in cattle?

What is silent heat in cows?

How far away can a bull smell a cow in heat?
A bull may be able to smell an in-heat cow some distance away if a breeze brings odors his direction. Bulls can often identify a cow in pre-heat up to two days before she actually comes into heat. A bull may keep close track of her — staying near and guarding her from other bulls — until she does come into heat.
