Oxytocin is another important hormone which allows the secretion of the milk to occur - also known as milk 'let down'. Prolactin a protein levels are stimulated when the udder is suckled by the calf or milked by the milking machine and this needs to occur for milk production to continue. Cows are usually dried off, or milking is stopped, about two months before their next expected calving to allow the udder time to rest and reset itself for the following lactation.
Dairy cows are selectively bred to produce high levels of milk and this is far more than a calf could normally drink. The volume of milk produced by a cow will depend upon various factors, such as her level of nutrition, breed, genetics and age. To produce milk, the mother cow must give birth to a calf.
Female calves can be entered into milking production or sold as veal. Because male calves are useless to the dairy industry, they are either shot or sent to veal crates. Regardless of sex, calves are taken from their mothers almost immediately after birth. This often causes significant mental distress for the mothers and impairs the social and physical development of the calf. Male calves who will be raised for meat undergo castration.
There are several different ways this procedure can be conducted. Other methods include cutting away portions of the scrotum and destroying testicles by removal or crushing. Also known as dehorning, disbudding is a process where the horns of young cows are removed. Horns can be burned away using caustic acid, or cut away using implements that resemble nutcrackers. The resulting open wounds invite infection and other painful complications.
Because of the painful nature of the procedure, and the fact that it is not necessary—it is merely a matter of convenience for people—many countries have banned the practice. Unfortunately, many countries, including the US and Canada, continue to allow tail-docking.
The dairy industry perpetuates the suffering, exploitation, and death of dairy cows. Many are prevented from ever setting foot onto grassy fields and socializing with other animals as they would in the wild. Although it is difficult to give up milk and cheese, doing so is the number one way to prevent the ongoing abuse dairy cows suffer on factory farms.
Plant-based cheeses are becoming more popular, and cellular agricultural companies are currently exploring ways to produce real milk without using any cows. Cutting back or cutting out dairy is a great way to help mother cows and their calves. There are several ways that you can help to improve the welfare of dairy cows. Sign up for our newsletter.

While a cow is taking a two-month rest, the farmer adjusts her diet, with the help of an animal nutritionist. This adjustment ensures she has the right balance of nutrients to promote a healthy birth. Dairy cows are ruminant animals. This means they have a unique digestive system made up of 4 stomach compartments, with each compartment playing a specific role in assisting digestion.
The rumen and the reticulum are primarily for eating and breaking down food into smaller pieces, whereas the omasum and the abomasum are used for digesting food. On average, a cow can produce anywhere between 25 and 40 litres of milk per day. This milk is stored in a sterilized bulk tank on farm, and a licensed milk truck grader picks it up every second day.
