4 Ways to Reduce Dirty Eggs - wikiHow

Management of nutrition and gut health is critical to achieving clean eggshells. Feed selection  is especially important, for example, producers must be aware of any anti-nutritional factors, toxins or contaminants contained in the feed that can lead to nutritional imbalances, enteric disease and overall poor bird health.
1. Fiber management
The amount and type of fiber in the diet can affect proper gut performance. For example, soluble fiber is difficult to digest due to its high NSP (non-starch polysaccharide) content. NSP increases gut viscosity and holds large amounts of water, which can lead to dirty eggs and other problems. Barley, rye, wheat or triticale all have higher non-starch polysaccharide content than sorghum or corn. Supplementing fiber with high non-starch polysaccharides containing enzymes (beta-glucanase and xylanase) increases the nutritional value of the diet and helps overcome problems.
Insoluble fiber has also been shown to be beneficial due to its abrasive action in the gut, enhancing the digestion of nutrients and improving gut health. Therefore, fiber components with high water absorption capacity should be added to the feed.
2. Performance is affected by particle size
Chickens benefit from feeding larger, coarser pellets as they develop larger, more muscular gizzards and longer guts. The increased retention time also stimulates a drop in pH, which has a bactericidal effect. Larger feed particles take longer to pass through the gut, which increases the length of the microvilli and increases the absorptive surface area of the gut, thereby positively affecting digestibility and nutrient absorption.
3. Control protein intake
Manufacturers must also pay attention to protein levels. Any excess will lead to increased nitrogen excretion, which can negatively affect flock health and the environment. Undigested amino acid and non-amino acid nitrogen moieties in the digestive tract serve as substrates for toxin-producing microorganisms. This substance damages the ileum, leading to overgrowth of pathogenic bacteria, imbalance of the intestinal ecosystem, intestinal irritation, dysbiosis and, in some cases, subclinical necrotizing enteritis.
Determination of BA (biogenic amines) in feed ingredients such as fishmeal or animal by-products helps to assess the quality and spoilage of materials prior to feed production. Furthermore, it is important to relate BA content to the bacterial load in the feed.
4. Probiotics can help
Beneficial bacteria must be part of the gut environment. It turns out that probiotics are an easy way to positively impact the population in your gut. Probiotics are live microorganisms that alter the dynamics of the gut microbiota to improve animal performance and health by combining different mechanisms of action.
The intestine is not only the main organ for the digestion and absorption of nutrients, but also the first defense mechanism against exogenous pathogens. When intestinal function is affected by pathogens, not only an immune response but also changes in passage rates, digestion, mucin secretion, and increased intestinal epithelial turnover occur.
Reduced feed intake results in higher maintenance requirements and diverts nutrients to strengthen the immune system. Energy and nutrients are depleted to mount an immune response strong enough to defeat the disease due to a disturbed microbial ecosystem, reduced absorption and digestion of nutrients (increased FCR), overstimulation of the immune system and consequent enteritis and significant loss of performance.
A multifaceted problem The
dirty egg problem is multifaceted. However, this problem can be improved to a large extent by using low NSPS cereals or NSPase enzyme supplements in the diet; increasing the use of insoluble fiber; using low protein feeds with the correct balance of amino acids, and limiting Use animal by-products to minimize the risk of high levels of biogenic amines. Finally, the addition of probiotics balances the gut environment, excluding pathogens and bringing balance to the most vital organs of the hen to support and enhance productivity and optimal egg quality.
