How to keep the growth or weight of chickens broiler uniform?

Answer

Dear. Mr. Basun, thank you for the question. The achievement of body weight will reflect the condition of the internal organs, both digestive organs, and respiratory. Weight should be controlled from DOC to harvest or reject. In addition to weight that needs to be considered is also the posture of the chicken. A qualified DOC is able to stand firmly and his legs are able to support his body well. Also, look at the wings.

Prime quality DOC has symmetrical wings and no broken wings down. The difference in body weight when DOC will largely determine the speed of growth. Make sure the DOC's weight is up to standard. Body weight is said to be uniform if the difference in body weight is +10% of the standard. If the expected uniform weight gain of chickens ability to eat and drink can be uniform. The condition of chickens with non-uniform body weight causes chickens with large body weight (exceeding the standard) will dominate while chickens with small body weight will be increasingly excluded and left behind.

The degree of uniformity of chicken body weight broiler it is said to be normal or good (standard) when it reaches ≥ 85%. Uneven or non-uniform body weight of chickens during harvest can be caused by several factors, such as:

• Quality DOC
• Feed management and quality
• Maintenance management
• Disease attack

To prevent this from happening in the period of keeping chickens broiler, perform the following anticipatory steps:

• Choosing a quality DOC

DOC selection carefully to get chickens with uniform body weight and according to standards. Characteristics of quality DOC include:

1. The magnitude is relatively uniform, with a degree of uniformity of ③ 85%. Body weight according to the standard strains chicken broiler preserved.
2. DOC looks active, responsive and agile.
3. The plumage is bright, not dull, and full.
4. The eyes are clean, open and shining.
5. The navel is clean, dry and well covered.
6. The cloaca is clean, there is no dirt.
7. There are no physical defects or physical abnormalities.
8. Nothing red hocks.
9. Has bright yellow leg scales and does not dry out.
10. It is not weak and quickly adapts to changes in the environment.

• Optimal maintenance management starts from the beginning of maintenance, especially during the brooding period,. Examples include:

1. Set the cage curtain open and close to facilitate air circulation in the cage.
2. The density of the chicken is suitable (not too dense).
3. Conduct routine cage temperature control, starting at 1-3 hours after chick in and continued every 2-3 hours at the same time with feeding.
4. Provide the number of feeders and drinking places according to the number of chickens and distribute them evenly.
5. Feeding schedule should remain every day and adlibitum (without limits). When the weather is hot, the amount of feeding during the day is reduced and additional hours of feeding are done in the early morning (04.00 – 06.00 WIB) or at midnight, ie at 00.00-02.00 WIB (midnight feeding).
6. Make sure the lighting at night is sufficient so that the chickens can still eat.
7. Provide quality feed that is free of mold and good nutritional content.
8. Perform weighing chicken body weight regularly every week from the age of 7 days. Routine weighing every week is also called body weight control. The weight control technique is to take samples of 50-100 heads of each cage evenly in each part of the cage. The weighing method should also be per individual chicken. Use scales that have higher sensitivity so that the body weight of the chicken per individual can be more carefully observed. This activity is carried out at the same time every week, for example Monday morning when the cache condition is empty.
9. If it is known that there are chickens with a body weight that is less than the standard, they are immediately separated and then given special treatment, that is, given sufficient and quality feed, multivitamins such as Broiler Vita, Vita Stress, Neobro, Fortevit (choose one) and herbal products such as Imustim and Kumavit. Setelah itu, untuk kelompok ayam yang bobotnya sangat jauh dari standar (<40% dari standar) sebaiknya diafkir dan tidak dipelihara lagi. Pakan dapat ditambahkan premiks (seperti Mix Plus BAM23A or Mix Plus BAP3A) containing multivitamins, amino acids, minerals, and enzymes to spur optimal growth and provide multivitamins (Fortevit or Neobro) to increase the body's resistance.
10. Do a thorough examination of chickens and note If there is a possibility of infection with diseases that can cause chickens to experience dwarfism such as infection Reovirus or helicopter disease. If this happens, consult the steps to be taken with a veterinarian or chicken health worker in the field.
