(a) Define balance ration in livestock production.
(b) Outline the stages involved in the preparation of each of the following animal feed ingredients. (i) bone meal. (ii) blood meal; (iii) fish meal; (iv) cotton seed meal;
(a) A balanced ration is a diet that provides all the nutrients in appropriate amounts to meet the specific nutritional needs of an animal for its desired level of production or performance. It contains all the essential nutrients like proteins, carbohydrates, fats, vitamins, minerals, and water in the correct proportions to maintain the animal's health, growth, reproduction, and production.
(b) The stages involved in the preparation of each of the following animal feed ingredients are:
(i) Bone meal: This is a by-product of the meat industry and is made from ground animal bones. The stages involved in its preparation include:
- Collection of bones: Bones from slaughtered animals are collected and cleaned.
- Crushing: The bones are crushed into small pieces or powder.
- Heating: The crushed bones are heated at a high temperature to remove any remaining tissue and fat and to kill any harmful microorganisms.
- Grinding: The heated bones are ground into fine powder.
- Packaging: The bone meal is packaged and stored for use as a feed ingredient.
(ii) Blood meal: This is made from the blood of slaughtered animals and is a good source of protein for animals. The stages involved in its preparation include:
- Collection: Blood is collected from slaughtered animals in a sterile container.
- Drying: The collected blood is dried by heat, spray or drum drying.
- Grinding: The dried blood is then ground into a fine powder.
- Packaging: The blood meal is packaged and stored for use as a feed ingredient.
(iii) Fish meal: This is made from whole fish or fish parts and is a good source of protein and omega-3 fatty acids for animals. The stages involved in its preparation include:
- Collection: Whole fish or fish parts are collected and cleaned.
- Cooking: The fish or fish parts are cooked to remove moisture and to coagulate the protein.
- Pressing: The cooked fish or fish parts are pressed to remove the oil and water.
- Drying: The pressed material is dried to remove any remaining moisture.
- Grinding: The dried material is ground into a fine powder.
- Packaging: The fish meal is packaged and stored for use as a feed ingredient.
(iv) Cottonseed meal: This is made from the cottonseed that remains after the extraction of oil. The stages involved in its preparation include:
- Collection: The cottonseed is collected after the oil is extracted.
- Heating: The collected cottonseed is heated to remove any remaining oil.
- Grinding: The heated cottonseed is ground into a fine powder.
- Packaging: The cottonseed meal is packaged and stored for use as a feed ingredient.
