Effect of evenness on production performance of broilers how to improve evenness of broilers

The evenness of chicken flock is an important sign to measure the growth of broiler breeders, and it is one of the main factors affecting the production performance of broiler breeders. According to the evenness of broiler breeders, the uniformity of production, laying rate, peak laying period, egg weight uniformity and flock survival rate can be predicted. In order to improve the production performance of broilers, attention should be paid to chicken flock uniformity from the first week.

Broiler breeder

First, create a good breeding environment:

The temperature should be balanced, the temperature difference between day and night should not be too large, it should be controlled within 3 ℃, and the temperature should meet the requirements, especially the relative humidity in the first 3 days should be more than 65%, so as to avoid the early dehydration of chicks; we should also pay attention to ventilation, ensure air quality, and determine ventilation according to the age of chickens.

Second, boil water, eat and add vitamins at the right time:

After long-distance transportation, chicks should boil water and food at the same time to alleviate transportation stress. 30 minutes before the arrival of the chicks, the drinking fountain and feed should be placed evenly, and the feeding should be fed less frequently, feeding 8 times a day in the first four days, and then gradually reducing the feeding times, so as to promote the development of the intestinal tract and immune system and improve the myogastric strength. Laying bedding paper in the area during the rearing period in the first 3 days is helpful to start eating early. Experience has proved that the chicks that get feed and drinking water earlier have better growth and development and higher body weight uniformity than those fed later.

Before 14 days of age, because of high temperature, dry air, small amount of drinking water and food intake of chicks, digestive organs are still in the stage of development, each time food intake is limited, at the same time, digestive enzyme secretion capacity is not perfect, digestive ability is poor. In this period, the premixed feed of nano-microemulsion compound vitamins has the advantages of high nutrient concentration, good palatability, easy digestion and absorption, and very good opening effect.

Third, cultivate an early appetite:

If the chicks do not form a good appetite in the first 4 days, it is easy to cause poor evenness; the broken particles should be fed within the first 96 hours, but not too fine.

Fourth, select chicks:

Through the observation of feeding and drinking water, the chicks that could not eat feed were selected, fed carefully and taken care of separately; after 2 hours of drinking water, the crop was checked to see how the chickens drank and fed; for example, there were still chickens that did not fully drink water and feed for 4 hours, the light, the height of the drinking fountain and the position of drinking water should be checked. At the same time, chicks need to be vaccinated with several vaccines in the first week, for example, weak chicks can be singled out and fed separately when they are vaccinated for the first time, and on the 3rd-5th day of vaccination, they can also be picked out according to their feel and crop and raised separately.

5. Provide sufficient effective material level and water level:

Pay attention to the uniform distribution of material level and water level, so that chicks can eat and drink water within 1 meter in 24 hours as far as possible. And with the increase of age, the number of material plates and drinking fountains gradually increased.
