Over the years livestock experts and nutritionists have tirelessly sorted and researched alternatives feed ingredients for corn and soybeans, which are extensively used in formulating livestock feed, especially for poultries and pigs.
Despite some hindrances like anti-nutritional factors, unavailability, palatability, etc, associated with these feed alternatives, there has been some progress in this aspect. For example, 15 % oat in combination with barley can replace corn without affecting overall performance. In the same vine, (Abdulrashid and Agwuaobi, 2009), reported that cocoyam meal will effectively replace maize at 25% (raw sundried) and 50% (boiled sundried) as a major source of energy in the diets of broiler finishers.
However, one of the major setbacks is the anti-nutritional factors found in these feed alternatives, but notwithstanding, nutritional experts have been able to produce some enzymes capable of enhancing the digestibility of these feed alternatives.
ok, enough of the intro...
So, in this post, I will show you the latest feed alternatives for maize and soybeans, their anti-nutritional factors, the amount in percentage that can be used, and the source. However, in this episode, the alternative feed ingredients are more common in America and Europe, and to a lesser extent in some parts of Asia and Africa. You can see alternative feed ingredients common in Africa here.
Ok, let continue...
Let us look at the value of what is being Replaced
Corn | Soybeans |
7 – 9% Protein | 36 – 48% protein |
1475 -1600 kilocalories per pound | 1050 (48% meal) – 1600 (Full fat roasted) kilocalories per pound |
Xanthophylls (yellow color) for yolk and body-color | 16 – 20% Fat – natural oils that provide non-starch energy. |
Available almost everywhere | Soybean meal is available almost everywhere. |
Cheap! | The cheapest source of protein! |
Next is alternative grains
The table below contains alternative grains for corn and soy.
Energy alternative sources for Corn | Protein alternative sources for soy |
Wheat | Peas |
Barley | Sunflower meal |
Grain Sorghum (Milo) | Linseed (flax) Meal |
Triticale | Camelina Meal |
Fish Meal | |
Crab Meal | |
Sesame Meal |
Limitations to feeding:
Fish flavor or paint like smell from the high oil content at levels above 30%
In conclusion, these alternative feed ingredients can not completely replace corn and soybeans due to their anti-nutritional contents. So, in using them you have to consider their limitations. Although, most of these alternatives are not largely distributed around the globe, which is one of the challenges limiting their use. Nevertheless, I hope other regions like Asia and Africa have potential feed ingredients untapped. So, it is left for the research institutions to carry out analysis on them and present their profile as those presented in this article.
