FAILURE TO CARRY OUT PROXIMATE ANALYSIS
Failure to carry out proximate analysis of ingredients that made up your formula is one of the major reasons for poor feed. Feed formulation is calculated based on the proximate analysis of ingredients used at arriving the nutritional requirements of the animal in question. For instance you may have a feeds formula which has been calculated with soya bean meal (47% cp), meal and fish meal (72%) at the feed mill; if you use same ingredients but with lower percentage crude protein, you are bound to produce less quality feed. The safe and best way to ascertain nutritional content of feeds ingredient is through proximate analysis. Some ingredients or raw materials may come with full analysis of its content. That will be of great help.
The best practice in feeds production is to carry out the proximate analysis of ingredients involved in the feeds formula.
I understand the fact that carrying out proximate analysis may be a serious challenge for many local farmers due to lack of access to laboratory and the cost of carrying out proximate analysis for each ingredient can be unbearable; nevertheless this is the best practice in producing balanced feed.
Failure to determine proximate analysis of ingredients makes many farmers to work with the recommended estimates by experts (this is also fairly okay) However, when working with the recommended values by experts, you will be on the safer side, if you assume to work with the lowest values recommended. For example, you might have seen proximate analysis of maize ranging from 7-10% cp. It will be better and safer you work with 7% cp when calculating feeds formula. The same principle should guide you in other ingredients.
