Study all aspects of calf rearing with this distance learning course.
Rearing calves is sometimes easy, and at other times can be very complex and challenging. There are many things that affect the ease with which calves are born and cared for after birth. With this course, students will:
- Understand the variables affecting the rearing of calves.
- Learn how to apporach and deal with different situations to produce healthy, young cattle.

Some Breeds are Easier to Raise
Different breeds have different characteristics, and depending upon what we want the cattle for, we may find greater benefit in one breed than another. Breeds differ in terms of many things, including; the ease with which they give birth, the quality of milk they produce for their calves, and the strength of their mothering instinct.
Today cow breeds can be broken up into four purpose types: Beef (meat), Dairy, Draft, and Multi-Purpose (Beef-Draft, Dairy-Draft, Beef-Dairy and Beef-Dairy-Draft). Many of the older breeds were breed as duel-purpose or multi-purpose cattle. Today we see most of the newer breeds specialise in one purpose, however they are more efficient at this specific purpose, i.e. beef cow breeds still produce milk but are nowhere near as efficient as the dairy cow breeds. They have a greater tolerance to ticks and parasites. Some breeds tolerate certain conditions better than others, while other breeds are more desirable because of the characteristics that are found in the milk or meat.
Characteristics We Might Value in a Cattle Breed
- Hardiness to climate – heat, humidity, cold, wet.
- Resistance to health problems – e.g. foot problems, eye problems, cancers, ticks.
- Size and growth rate.
- Colour – skin, hoof and eye colour can have a relationship with health issues. Colour of coat may affect heat or cold tolerance.
- Fertility and Calving – When it starts, how many years it lasts, how easy calves are produced, how much work is involved raising calves, etc.
- Gestation and birth weight.
- Milk production – quantity or quality, ratio of fat to protein, type of protein, etc.
- Meat Production – quality and quantity, rate of growth, tenderness, marbling, etc.
- Temperament – docile cattle may be better for dairying or draught animals.
- Horns or no horns (i.e. Polled) – horns can make cattle more difficult to manage.
- Lack of genetic defects.
The Birth is only the One Part of the Job
Production of calves involves caring for the mother during pregnancy; managing the birth, and ensuring the calf develops properly over a period after it is born.
Typically, a calf will begin to breathe and struggle to its feet immediately it is free of the cow. It should also attempt to suckle very soon after birth. This is an important process upon which much of the subsequent health and growth potential of the calf depends.
If the calf is slow to start breathing, the following methods may help:
- Clear any membranes or mucus from the nose and mouth.
- Hold the calf by the hind legs and swing it around a few times.
- Insert a fairly rigid piece of straw well up into the nostril and moving it up and down may stimulate breathing.
- Place the calf on its brisket with its front legs pointing forward and apply intermittent pressure to the lower part of the chest.
- Throw a bucket of cold water over the head and chest of the calf.
- If all else fails (and you are really keen) blow into the calf’s mouth in ‘mouth-to-mouth’ fashion.
The first milk from the cow is called colostrum and, among other things, it contains immunoglobulins that can provide protection against disease for the calf until its own immune system can develop.
Both the level of immunoglobulins and the calf’s ability to absorb them quickly diminish after birth. For this reason, it is important that the calf receives at least one good colostrum feed (2 to 4 litres) within the first six hours of life.
Two elements of calving management that make a big difference to new born calf health are:
- Pathogen exposure.
There are a number of good management factors that occur prior to calving that can reduce the chances of a difficult calving. In addition to this, management practices at calving can make a difference to how much assistance is needed by the cow. In difficult cases, timely diagnosis and intervention can affect the amount of assistance needed and the subsequent amount of stress on the calf.
Managing Pathogen Exposure
A clean calving environment is always better than contaminated or dirty environment. Make sure that the cow, the bedding, and the air are as clean as possible. If assistance is needed ensure that aseptic practices are followed as closely as the environment will allow.
