Premix additives are complex mixtures of vitamins, minerals, trace elements and other nutritional additives that can be added to feedstuffs. Moisture, light, oxygen, acidity, abrasion, fatty acid rancidity, carriers, enzymes and drugs can affect the stability of vitamins and other trace elements in premixes.

Shell quality is a key component of overall egg quality and a top concern for producers, as 80-90% of egg quality decline is the cause of shell cracks. Eggshell quality starts early, as most of the factors that make an eggshell weaker or stronger are determined before the egg is laid. These influencing factors are diverse, including the age and breed of the bird, housing systems, nutrition, stress and disease. One of the most consistent factors in eggshell quality decline is the age of the hen. Later in a hen's life, calcium deficiency can lead to reduced eggshell weight and shell strength.
Eggshell quality is greatly affected by nutrition, primarily by providing adequate calcium to older hens to help them maximize their production cycle. At the same time, careful attention must be paid to key ingredients such as zinc, manganese and vitamin D. These nutrients, which must be ingested in adequate amounts by the hens, may result in poor eggshell quality if they are currently deficient in the diet.
