broiler chicken feeding system

Technical points and popularization and application of broiler cage raising

With the increasing living standards of people, people are increasingly demanding the quality of livestock products, especially the inherent quality of products. The production of broiler chickens in China's peasant households will continue to use the previous plastic sheds and it is difficult to meet domestic and international markets for chicken products. The quality requirements, especially the problem of drug residues, and the difficulty in controlling the disease caused by the poorly equipped chicken house and equipment, and the weak biological safety capability, have resulted in low economic returns for broiler chickens. The commercial broiler cage technology, which is raised on the ground, does not contact with feces, eliminates the residue of coccidiosis drugs and reduces the incidence of intestinal diseases, greatly reducing the amount of drugs, thereby reducing drug residues and medication costs, and reducing The cost of medicines lays the foundation for the production of green, pollution-free food, and at the same time it reduces the area by 30% to 40% due to the adoption of 3-layer cages to increase the stocking density. It is worthwhile for grass-roots animal husbandry workers to promote and apply it vigorously.

The main technical points of broiler raising

The main technical points of the new technology model for commercial cage broiler cage technology: (1) Adopting three-layer overlapping cages to support large-scale feeding of commercial broilers, that is, raising them from the first day of brood until the slaughter, raising the stocking density and maximizing The hen house and land utilization rate are convenient for feeding and management. (2) Adopt phase-by-stage expansion cage culture, that is, 21 days before the breeding period, intensive small-scale brooding, save heating costs, and gradually expand the group after 21 days. (3) Improve cage material and structure, so that the incidence of breast broilers in broilers is greatly reduced, and the incidence of breast cysts is less than 7.5%. (4) During the brooding period, the lower half of the net before the cage is designed as a "pear-shaped", and it is adapted to the feed needs of the entire broiler broiler by adjusting the baffle. (5) According to the nutritional needs of caged broiler chickens, study and design the corresponding feed formulation to meet the needs of growth and development under high density cage conditions. The vitamin content of the feed formula is increased by an average of 20% from the ground level raising standard, which is suitable for caged chickens. (6) Cage-reared broiler coops must be fully-closed dormitories without windows. The exhaust air is exhausted by exhaust fans, and fresh air enters the house from the air intake. Artificial light is used in the house instead of natural light. When the temperature is high, the wet curtains should be installed to cool the chicken house. In the cold season, artificial heat can be used or the chicken's own heat can be used to keep the temperature inside the comfort zone.

2 ,advantages and disadvantages of broiler cages

Ground and net broiler chickens have a large amount of activity, a long feeding period (60 days), and chickens consume more material. It is difficult to observe the flock and it is difficult to manage and the mortality rate is 5%. The broiler breeding cage technology is a new breeding mode developed through years of research and development. The advantages of caged broiler chickens are: First, it is more than 1 times higher than the flattening density; Second, the range of chickens is small, energy consumption is small, easy fattening, can save feed 5%-10%; Third, the chicken does not touch the feces, control The occurrence of coccidiosis and the infection of white peony disease have improved the survival rate and saved the cost of medicines. The fourth is the convenience of mechanized management and the improvement of labor efficiency. The fifth is the absence of litter and saving of litter expenses. The disadvantage is that the cost of the equipment is high, and the construction cost and production cost of investing in a multi-cage broiler house are significantly higher than in open chicken houses.

3 ,Popularization and Application of Broiler Cage Culture Technology

In recent years, through the promotion and application in Gaomi City, Shandong Province, the company has accumulated more than 200 breeding broiler chickens, over 3 million broilers, and more than 100 million broilers. Through the whole cage feeding experiment, it was proved that the average slaughter weight was above 2.50kg after 41 days of feeding from cages to cages, the ratio of meat to meat dropped from 1.8-2.0:1 to 1.6-1.7:1, and the mortality rate decreased from 5%. To 2%, the growth rate is fast, and cage rearing is 5-7d ahead of net raise, which saves costs. The average economic benefit is not less than 3 yuan per chicken, and the net income of each chicken is 35% higher than that of the ground, which is significant. Improve the economic benefits of breeding.

4, experience summary

The large-scale broiler chicken cage raising technology meets the requirements of standardized production and pollution-free livestock products, laying a good foundation for breaking the international market technical barriers. Commercial broiler breeding management science, production results are good. The successful experience of broiler scale cage technology is as follows: save the house, improve the utilization rate of the house 40% (can be raised from 10/m2 to 14); easy to manage, save labor, increase the labor rate by 50% by 3,000 per person Only raised to 6,000; limited by the limited activity of chickens, reducing the sports consumption, thereby increasing the meat and meat ratio, and improving the feed utilization rate of 5%; because chickens are isolated from the ground and feces, can effectively control coccidiosis; no pad The material eliminates the bacteria and microbe breeding environment, controls secondary infections of many diseases, increases the survival rate by 2.8%, facilitates the cleaning of the excreta, improves the sanitation of poultry houses, and reduces the labor input.
