Egg Layer Concentrate, Economic Feeding

In recent years, breeding programs have mostly been oriented towards the improvement of quantitative indicators (production percentage, egg weight, etc.) and qualitative indicators (strength, eggshell thickness, etc.) in egg layers. By applying scientific and specialized management in rearing egg layers, the incidence of some common abnormalities in this industry can be prevented. Given the role of nutritional management in rearing egg layers, awareness of nutritional needs and economic aspects of the diet, are of particular importance. In this regard and in order to increase the productivity in laying hen units, Sepahan Daneh Company has taken action to produce a new and different product; named "egg layer concentrate" in order to increase the productivity in egg layers production units, and accordingly has made it possible to achieve the best performance results and improvement of economic efficiency in egg production.

The importance of the egg layer concentrate in the diet

Among the most important characteristics of a suitable concentrate, is providing the nutrients needed by the poultry's body and being economical. The two-step special concentrate and the recommended diets are regulated based on the standardized ileal digestibility (SID) of amino acids, in such a way that the amount of digestible amino acid, lysine is used as a standard for the diet, and the amounts of other amino acids are regulated according to it. One of the most important factors in the formation and strength of eggshell is the supply of minerals and vitamins.

Minerals have been supplied in these concentrates in a manner that not only they are not incompatible with each other, but also, with a positive impact on each other, they increase the bird's power to utilize the minerals (Figure 1). And also with trace minerals such as zinc, manganese, etc., having a positive impact on major minerals such as calcium, phosphorus, etc., these concentrate improve the eggshell quality and its strength. Due to the exclusive formulation of these concentrates, the egg production and feed intake indices, which are highly bound to the economic issues of layers, can be improved.


The characteristics of the egg layer concentrate diets

Since the periods of rearing and production of layers are long, nutritional management in this industry, is of particular importance. Due to the significant difference of the nutritional needs of rearing and production periods in layers, supplying all the nutrients needed for appropriate production, only by using single-step concentrate from the beginning to the end of the period, is difficult. On the other hand, performance indices in layers, are highly bound to the economic issues of the diet. Therefore use of specialized concentrates specific for the rearing and production period, seems to be necessary. To achieve the maximum production and its continuation, the diets have to be regulated in such a way that all nutrient needs (amino acids, vitamins, and minerals) are supplied as best as possible, and the occurrence of nutritional and rearing stresses are prevented. Use of the phytase enzyme in the combination of the special concentrate causes the breakdown of phytate molecule (Figure 2) and release of energy and amino acids in the diet. Moreover, phytase causes the release of calcium, phosphorus, magnesium, zinc, iron, and manganese, and also enhances the absorption capability of calcium, phosphorus, and minerals. In addition, the diets are formulated based on the amount of sodium and chlorine in the water being consumed (salinity), and then they are recommended, so that the anion-cation balance along with potassium in the diet can be maintained properly depending on the amount of feed intake, and the age of layers. Addition of the amino acid threonine (the third essential amino acid in poultry feeding) to the special concentrates, causes the balance of amino acids in the recommended diets, are maintained properly, and this improves the efficiency of use of nutrients in the diet. Also the use of a multi-enzyme (a set of specific enzymes) in the special concentrate has made it possible to regulate economic diets including wheat, barley, sunflower meal, canola meal, etc. Hence, the special concentrates of Sepahan Daneh Parsian Company are regulated in such a way that it can supply all the nutrient needs in the rearing and production periods, and increase the production efficiency in layers.

The performance of the special concentrate in egg layer flocks

Many factors affect the production performance in layers. For instance, having an appropriate rearing period is the most important among these factors. The homogenous growth and having a proper weight in different age periods, are among the characteristics of using the two-step special concentrates in the diets, and provide the physiological conditions necessary for entering the first step of egg laying, and for achieving the maximum production. Given the importance of the impact of the qualitative parameters of the eggshell on the production performance of layers, it seems necessary to minimize the percentage of broken and abnormal eggs. In desirable rearing conditions, use of the two-step special concentrates significantly reduces the number of broken and abnormal eggs, and improves the qualitative parameters of eggshells. Since the production efficiency is directly related to the production percentage, the qualitative parameters of the eggshell, and feed intake, and this indicators (production efficiency) in conjunction with economical diets increases the productivity of the poultry farmer, thus the use of the special concentrates of Sepahan Daneh Parsian Company improves the production efficiency and enhances the productivity in egg layer flocks.

Egg Layer Flock Management - Eggshell quality deterioration

A) The imbalance of nutrients in the diet:

Deficiency of major minerals (calcium and phosphorus) and trace minerals (zinc, manganese, etc.)

- Excessiveness of some minerals (especially calcium) and their antagonistic effects on the absorption of other nutrients

- Disproportionality of calcium to phosphorus ratios in different age periods

- Deficiency of different types of vitamins, especially vitamin D3, which plays an important role in the absorption of calcium and phosphorus.

- Deficiency of some amino acids such as lysine and threonine which play an important role in the synthesis of the matrix protein of the eggshell.

- Lack of dietary cation-anion balance which will result in metabolic diseases including respiratory acidosis and alkalosis, and in turn will reduce the eggshell thickness. Among the issues causing the lack of dietary cation-anion balance, is the high sodium level of the water being consumed (the water salinity).

B) Inappropriate ventilation: Lack of appropriate ventilation will increase gases such as ammonia, carbon dioxide, etc. in the poultry house that paves the way for respiratory diseases, and as a result will reduce the eggshell quality.

C) Heat stress: Excessively high temperatures will cause high carbon dioxide excretion from the poultry's body and reduce the eggshell quality.

D) Lack of proper lighting management: The major part of eggshell calcification occurs in the period of darkness when the bird does not eat. Hence, lack of proper lighting management will reduce the eggshell quality and increase abnormal eggs.

E) Diseases such as Newcastle, flu, bronchitis, and egg drop syndrome will cause the production of abnormal eggs.
