Raising laying hens at present, the breeder will either raise the chickens themselves or buy them. young hens come to feed The best predictor of future egg production efficiency was the weight of the hen. and uniformity of the herd (Uniformity) is an important criterion for the quality of hens. focus about the development of organs or systems in each age This is very important for raising young chickens as well. by increasing the importance of what we do not see That is the integrity of the organs. Inside the animal that is ready to provide high egg production efficiency. and quality of egg production that is good throughout the life of laying hens? Look beyond 1. Body weight uniformity of the herd and development of important organs in young hens. raising chicken models We attach importance to body weight.
Table 1 Efficiency of broiler generation and uniformity of the herd (Uniformity). having a uniform value of more than 85% is considered the heart of efficiency in raising young chickens. Management and rearing programs, strangulation, vaccine programs, nutrition management. including the quality of food and water, the amount of food consumed Management of lighting, stress management.
The development of various organs that are important during the laying period of hens. What organs are developed in each generation of chickens? regarded as the heart of management cooking recipes And it is important to choose the use of various additives. which has a large number in market to be related to the development of organs correctly and with the highest efficiency in each age of the hens
The integrity of the pectoral muscles is considered there. extremely important because it is an indicator that the young chickens have developed enough and allow us to anticipate forecasting the production of laying hens in the future pectoral muscles that is important because it contains glycogen This is a fast energy source for egg production. breasts that are not perfect enough causing the chicken to have no energy sufficient for high egg production and unable to stand, the period in which the score of the pectoral muscles of the chicken will Begin to produce eggs that are suitable should be graded at about 2-3, can be considered as a complete pectoral muscle.
bone growth, especially the medullary bone
The bone marrow is the most important bone in laying hens. It acts as a reservoir of minerals. Calcium is a mineral that is important for the formation of egg shells. which will begin to develop and retain calcium when chicken The chicks are about 15 weeks old to be used as a reserve source of calcium. Therefore, the pre-lay diet for chickens is to be started by increasing the amount of calcium in the feed before the first egg laying. To increase the accumulation of calcium is important.
Medullary bone structure, 16 weeks old chicken
Medullary Bone The structure of the bone marrow (Medullary bone) when it starts to produce the first egg.
Eggshell weight of 1 egg weighs approximately 5.5 g. It comprises about 2.2 grams, which is almost 50% of the total eggshell weight.
It was found that 60-80% of the main source of calcium was obtained from the feed that the chickens ingested. and the rest The chicken body will extract the calcium that has accumulated in the portion. Bone marrow is used to make eggshells, so maximizing the calcium deposits in the bone marrow is critical to the quality of the eggshell.
