In theory, profitability in fish or shrimp farming is simply the ability to keep farm inputs at a cost below the selling price of harvested animals. This is easier said than done - often, farmers want to get the best quality input for their animals but in doing so, their bottom line suffers. Digestive enzymes offer a cost-effective means of enhancing feed quality and improving growth within the culture.
The problem of slow growth frequently is caused by not just one but several factors:
- quality of the fry
- good management of pond parameters
- good quality feed
Assuming all the above factors are all at optimum level, the addition of digestive enzymes in the feed can enhance growth. This can be done either by top-dressing or by inclusion into the feed during milling. Two such products are DE110F (for fish) and DE201F (for shrimp). Similar formulations are also available for the inclusion of digestive enzymes during the pelletizing process (DE610F or DE701F). These digestive enzymes neutralize systemic toxins and waste matter from inside the animal and increase bioavailability of feed ingredients, hence improving survival and growth rates.
By adding digestive enzymes to the feed, animals are able to increase nutritional uptake and improve both feed performance and bioavailability. Because feed ingredients vary widely from batch to batch (due to substitution or multiple sourcing), the content or caloric quality likewise differs. Hence, precise supplementation of crude proteins or amino acids is almost impossible: any addition of proteins or amino acids will likely fall below or above expected levels. With the addition of digestive enzymes, higher performance can be expected even from standard feed ingredients, allowing feed manufacturers to achieve a modicum of quality from batch to batch.
