Animal Feed and Nutrition

Different types of animals need different types of food.

Cats don't eat the same things as dogs and pigs don't eat the same as chickens. Apart from variations within a species; there are also variations according to where the animal is kept, and what it does. Animals that exercise a lot, need energy to fuel their movement. Growing animals need food to increase their size. Old animals may not need to eat as much. 
Feeding is the most important factor in successful animal care. An animal will only perform at it's potential if it is fed well. Being 'well fed' does not imply being 'over fed'. An animal that is fed well is given just enough (but not more) of the correct foods so that it can realise its production potential.

To feed more than necessary would be wasteful and uneconomical and could lead to health problems in animals. A successful farmer or pet owner will feed at the 'optimum level'. In other words, he will feed just enough (but not more) that is need for optimum health or production.

It requires a great deal of skill, knowledge and practice to be able to feed animals optimally. The first step is to gain a good understanding of the different types of food that can be fed to livestock. The second step is to learn how the different foods can be mixed together to form balanced rations for animals.

An important step is also to observe animals around you. By noting what they are fed and how well they seem to be doing, you can begin to develop an eye for feeding animals well. This step will never be completed for there is always something new to learn about the way different animals respond to food. In addition, new foods are constantly being developed, and it will be up to you to try them out and see if they work for your animals.

How Much Food
Too much food can be as bad as too little. Over feeding animals can lead to obesity and health problems. Under feeding them can also lead to health problems.
The ideal maintenance ration is the amount that would allow the animal only enough to stay in the initial condition (ie: to support life with no product, no gain, no loss of body substance). It is the minimum amount of food required to keep the animal alive. This can be particularly important for maintaining stock when there is a shortage of feed (e.g. drought conditions).
Balanced Maintenance Ration
This definition has two parts. 'Maintenance Ration' here refers to a feed mixture which is just sufficient to meet the requirements of a specified animal in a 24-hour period. The animal receiving the ration will neither lose nor gain weight. 'Balanced' means that the proportion of carbohydrate, fat and protein in the ration is correct.

ANIMAL FEED AND NUTRITION (BAG202) (Formerly Animal Husbandry lll)

By studying this course you will develop a broad understanding of to the correct feeding of domestic animals (farm animals and pets) for health and productivity. Though focussed mainly on domesticated animals thew course is nevertheless still a valuable training opportunity for anyone involved in even care of wild animals.
