Feeding and management scheme of laying hens during laying period

Many people think that raising chickens is very simple, but raising chickens in bulk is directly related to your profits. if you don't learn the techniques of raising chickens well, you may cause economic losses. the laying rate of laying hens has a lot to do with the feeding and management of the laying period. but it will have a serious impact on the laying rate of laying hens, let's learn the feeding and management plan of laying hens.

Management scheme of laying period for laying hens

1, the selection of laying hens is very important, to choose and buy high-quality laying hens, or a certain breed to choose high-quality and healthy chickens. The weight and evenness of young chickens are the most important factors in determining egg production in the future. Heavy chickens start laying first, and chickens of the same breed can be laid at the same time if their evenness remains the same. The laying rate increases rapidly and reaches the peak within 2-3 weeks. Low-weight chickens start to lay late. The physique is weak, the disease resistance is poor, there are few eggs, the egg laying rate rises slowly, and even there is no egg laying peak. Excessive fat chicken, the body burden is heavy, the egg is small, also won't last, the weight of the chicken is roughly fixed at the age of 7-14 weeks, the thin chicken, if the weight is still too small at this time, it is too late to strengthen nutrition, so we should pay attention to the nutrition level and management in the early stage of breeding chicken.

2. Young chickens have the ability of self-control of body temperature, and their digestive ability is becoming more and more perfect, their appetite is exuberant, their food intake is increasing, and their ability to absorb calcium and phosphorus is increasing. 7-12 weeks is the period of the fastest growth of bones, muscles and internal organs. After 13 weeks, there is an important period for the growth of abdominal fat. Too much fat will affect egg production in the future. Therefore, nutrition in this period should not only ensure rapid growth, but also prevent fat accumulation to make it overweight.

3. During the breeding period, all kinds of immunization should be done as well as possible, and vaccination should be carried out under the condition of healthy chickens, so as to avoid re-vaccination in the laying period due to low or uneven antibody levels, resulting in emergency losses.

4. The reproductive system develops rapidly. The reproductive system began to develop at 12 weeks of age and developed rapidly at 18 weeks of age. Therefore, 18-week-old eggs should be gradually replaced by prenatal egg feed, supplement a certain amount of protein and calcium, promote the smooth release of ovaries and fallopian tubes and accumulate a certain amount of bone calcium, in preparation for the smooth start of production. However, it is not advisable to change the material too late and too quickly.

Matters needing attention in each stage of laying hens

1. Observe the chicken flock and establish a system of regular observation and regular inspection of the chicken flock. Observe the spirit, appetite, drinking water and feces of the chicken every day, and find out the cause of the abnormality in time and deal with the symptoms. Discontinued chickens and disabled chickens can be eliminated regularly.

2. Maintain good and relatively stable environmental conditions: ⑴ feed quantity is stable, material level and water level are sufficient, ⑵ light should be constant (16 hours), no man-made stress; ⑶ inspects eggs regularly and makes daily records.

3. Laying period (19mur23 weeks old, 24mur42 weeks old, over 43 weeks old)

⑴ 19Mel 23 weeks old, 50% of laying hens are in a physiological stress period, when the reproductive organs expand rapidly and estrogen levels surge, so the chicken's endocrine and gastrointestinal tract are in a state of stress, and there are normal loose stools at this time, which is a physiological protection. The addition amount of stone powder is 4% when the egg laying rate is 5%. If too much stone powder causes stress, it will affect the production performance of 2mi in the next 4 months, and any drugs will be ineffective.

⑵ 24Mel 42 weeks old is the consumptive laying period, during this period, the laying rate should be steadily decreased to prolong the peak period of egg production. From the age of 24 weeks, the egg laying gradually reached its peak and the weight increased until the age of 30 weeks. Body weight decreased significantly after 30 weeks of age, especially at 36 weeks of age. The growth stopped completely at 42 weeks old, and the weight gain after 42 weeks old was completely fat deposition. If the chicken is too thin, it will depilate and stop production.

The feed nutrition during the laying period of ⑶ must be at full price. If the chicken is replaced with poor feed, the laying rate will not change much within a month, but the body weight will decrease, and the nutrients in the body will be converted into eggs, which is called consumptive egg laying, and will stop laying in advance in the later stage.

Laying hen premix formula

1. Chicken (1-60 days) formula: ① corn 62%, wheat bran 10%, bean cake 17%, fish meal 9%, bone meal 2%. ② corn 60%, wheat bran 10%, bean cake 22%, fish meal 6%, bone meal 2%.

two。 Young chicken (61-120 days) formula: ① corn 55%, wheat bran 20%, bean cake 7%, cottonseed cake 5%, rapeseed cake 5%, fish meal 5%, bone meal 2%, shellfish meal 1%. ② corn 66%, bean cake 18%, sunflower meal 11%, fish meal 3%, bone meal 1.5%, salt 0.5%.

3. Feed formula for laying period: ① corn 56%, miscellaneous grains 10%, wheat bran 6%, bean cake 17%, fish meal 5%, shellfish meal 3%, clear stone 3% (methionine 0.1%, salt 0.4%). ② corn 68%, wheat bran 6%, bean cake 8%, fish meal 10%, bone meal 2%, shellfish meal 6%.

All raw materials processing and finished products meet the guidelines for the use of green food feed and feed additives and must be inspected and approved by the Green Food Office at or above the county level before use.

Selection method of laying hens

First, distinguish from the color. Laying hens have yellow legs and mouth before laying. For high-yield chickens, the heavier the discoloration is, the higher the laying rate is. At the age of 250-300 days, the chickens with yellow legs and yellow mouth are still low-production hens, even non-laying hens. The chicken that lays white shell eggs has yellow legs and mouth, while the chicken that lays pink shell eggs has brown legs and mouth.

Second, distinguish from the chicken crown. The crown of high-yield chicken is red, soft, delicate and warm, inverted to one side and normal red. Low-production chickens, or even non-laying chickens, the crown can not fall, there are white spots or white frost, the crown is thin.

Third, distinguish from feathers. Feathers earthy, dishevelled, not oily, not smooth, neck, back, chest feathers fall off or bare for high-yield chickens, such as often dressed up, such chickens are low-yield chickens.

Fourth, distinguish from the anus. Anal broad muscle relaxation, squeeze the broad muscle around the elastic, moist feeling, and immediately contract, the flow of sticky secretions, such a chicken is a high-yield chicken. The anus tightens, the surrounding muscle abdomen squeezes without elasticity, and the chicken with no sense of wetting is a low-yield chicken.

Fifth, distinguish from the situation of feeding. When feeding, high-yield chickens, such as hungry tigers, gobble up, have a strong appetite, do not look up, are not picky, and eat quickly. Pick food do not like to eat, even the feed only peck but do not eat the chicken as low-yield chicken, or even do not lay eggs.

Sixth, distinguish from feces. High-yielding chicken feces are shaped into small heads with white, drink more water in summer, and are basically shaped with normal color. Low-production hens and non-laying hens have slender feces and more dry feces.

7. Distinguish from the pubic bone. There are 3 and 4 fingers of pubic bone in high-yield chicken. Low-yield chicken pubic bone 2 fingers, or even 1 finger crotch.

Eight, distinguish from the abdomen. The belly of a high-yielding chicken is broad. The abdomen of the low-yield chicken is narrow and thin, and the sternum is like a blade.

9. Identification of chicken thieves. Deal with chickens that steal eggs: for chickens that peck eggs in an upward cage, they can be transferred to the upper cage; chickens that stretch out their necks and hook eggs with beaks should be eliminated or put into a single cage.

Ten. Distinguish from the sound of a chicken. The sound of high-yielding chickens is loud, neat and uniform, indicating that the laying hens are healthy. Chickens that have not laid eggs for a long time do not bark or keep watch. When abnormal animals and other small animals are found in the chicken farm, they immediately yell to cause a large group of scares and lay soft-shell eggs.

The feeding and management of laying hens during the laying period is very important, which directly affects the laying rate of laying hens, so we should pay attention to the unreasonable preparation of feed, incomplete or unbalanced nutrients, erroneous drug use of laying hens, the interference of disease will affect the laying rate and egg quality, good management can obtain good profits.
