Yes. A cow that is not producing milk is called a dry cow. Dry cows are those that are a result of the weaning process, and are granted a period of rest before giving birth again.
For beef and dairy cows, lactation period begins immediately after a calf is born. For beef cows, the lactation period ends when their calves are weaned off of them. For a dairy cow, the lactation period ends when she is not longer being milked and allowed to dry up so that she can focus on putting energy into growing the calf inside her. The dry period for a dairy cow is shorter than a beef cow's: two months for a dairy cow, and four to five months for a beef cow.
Dairy cows, even though they are not lactating, still have higher nutritional demands than dry beef cows, so baleage (a form of silage) is a recommended feed to feed to them.
The gestation period of a Chauri cow (which is a cross between a yak and a domestic bovine of Bos primigenius indicusbreeding) is around 9 to 10 months in length, which translates to around 290 to 315 days in length.
The gestation period. You can also call it the pregnancy period as well.
The period is proportional to the square root of the length so if you quadruple the length, the period will double.
If there's grass growing there, yes.
The period of a pendulum is directly proportional to the square root of its length. As the length of a pendulum increases, its period increases. Conversely, if the length of a pendulum decreases, its period decreases.
The period increases too.
No, not milking cows will not make them sick. Their udders will just be sore for a few days, then eventually they'll slow down in production and dry up.
The time when cows are not producing milk or lactating.
Technically and mathematically, the length is the onlything that affects its period.
