Improve broiler product grade 4 measures

Due to catching, loading cages, transportation and other reasons, broiler chickens often cause scratches, bruises, knife wounds, and fractures, which can cause the products to be downgraded, and the incidence rate is 16.82%. Therefore, in order to ensure that broiler chicken products are marketable, improve the grade of goods, and increase economic efficiency, some effective technical measures must be taken.

First, the measures to ensure the color of the product in different regions, different people, the love of chicken skin color is not the same. Europeans like golden yellow chicken skin, Americans like milky white, and some regions in China and Southeast Asia like yellow chicken skin. In order to meet the requirements for the appearance color of products in the sales area, the following measures can be taken:

1. There are no black-haired chickens, black and black chickens, and black and black chickens.

2. Feeding yellow pigment feed During the rearing period of broiler chickens, yellow corn or yellow pigment should be added to make the chicken yellow.

3. When slaughtered, control the temperature of the armpits, such as scalding water temperature does not exceed 65 °C, the leather will not fall off, after processing the chicken remains dark yellow; if the water temperature exceeds 65 °C, the leather was hot off, the carcass was milky white. What kind of water temperature and processing methods are used mainly consider the flow of goods and the preferences of customers.

4. To prevent trauma in the rearing period, slaughter chicken, transport, slaughter should pay attention to prevent collision, extrusion, so as not to cause blood vessel rupture, subcutaneous congestion, affecting the skin color of goods.

Second, there are many reasons for injury caused by measures to reduce trauma, such as excessive stocking density, crowding during growth, and brutal and brutal operations during capture and shipment, which are likely to cause injuries. To prevent injury, the following points should be noted:

1. The density should be reasonable during the breeding period. The litter in the house should be slightly thicker. The playground should be flat and free of sharp hard objects.

2. When catching, use fence to carefully enclose. It is best to use light blue or red lighting to catch chickens after dark or before dawn. Do not disturb the flock before catching them to prevent them from bursting.

3. Special chicken cages are used for transporting chickens, and soft grass or grass mats should be laid on the bottom of the chicken cages. Do not leave hooks and stabs on the cage net to prevent stab wounds on the body surface. At present, there are plastic folding chicken cages on the market. When loading and unloading vehicles, they should be carefully lifted and lifted to prevent tilting to one side.

Third, as soon as possible slaughter, to ensure that the quality of meat to broiler chickens to reach the market weight of the breeding period is shorter, the more the consumption of materials, but also more cost-effective, and the meat with the growth of age, its fine, tender, juicy It will get worse. Therefore, from the perspective of improving meat quality, as long as the market weight is reached, the shorter the feeding period, the better.

Fourth, timely stop feeding drugs and fish meal In the rear of the breeding, about half a month before slaughter, should stop feeding the drugs that can affect the taste of chicken and fish meal feed.
