The formula and processing of broiler feed is the most critical factor affecting feed conversion ratio,there are also factors such as temperature, light and disease.With the development of the scale and industrialization of broilers, the farm has gradually applied fine breeding to production practices during the breeding process. When it comes to fine broiler farming, we have to talk about the feed conversion ratio of broilers. Feed conversion ratio plays an important role in breeding, because it is related to the production efficiency of the farm and the size of the breeding profit.
Broiler feed conversion ratio（FCR） is the amount of feed consumed by broilers per 0.5 kg of meat product. Farmers need to comprehensively analyze many factors when calculating broiler feed conversion ratio, because there are many factors that affect the chicken feed conversion ratio, and they must also pay attention to these aspects in the feeding and management process. Next, Richi Machinery will analyze the common factors that affect the ratio of feed to meat, and hope to help you.
(1) Temperature effect
Broiler farming has a very strong temperature dependence. In the brooding period, the temperature required for the chicks is 33 ℃ ~ 35 ℃, and as the age increases, the temperature should be gradually reduced until 25 ℃ stable. In this breeding process, if it is summer, in addition to the need to provide temperature in the early stage, the heating facility can be removed in the later stage. However, in winter in the north, the temperature must be kept warm throughout the entire journey.
In order to reduce the cost of breeding, some farms try their best to control the cost of heating. In this way, the chickens can increase the feed intake and increase the growth rate. As everyone knows, the temperature in the chicken house does not reach the growth requirements of the flock, and it will indeed increase the feed intake, but after the feed enters the body, a large part will be converted into heat to protect the cold, and some will provide energy for daily activities. The rest will be used for growth and weight gain. In the long run, the feed consumption is high, but the weight of the flock does not increase proportionally, resulting in a higher feed conversion ratio.
(2) Influence of light
Under normal circumstances, broilers are given full light in the early brooding period, and then reduce the light, so that the purpose is to give the chickens sufficient rest time, and then let the feed enter the body to fully absorb to achieve the effect of growth and weight gain. If the house is kept full of light for 24 hours, the flock will not be able to rest. Although the feed consumption is increased, because the intestinal tract of the chicken is relatively short, plus the appropriate amount of activity of the flock, the feed cannot be fully absorbed in the body Excreted. The result of this is that the feed consumption is increased but not converted into nutrients in the chicken body and absorbed, and the consequence is that the feed conversion ratio is relatively high when slaughtered.
2. Feeding management factors
In any breeding, feeding management has a decisive role. The purpose of broiler farming is to grow fattening quickly. In a breeding cycle, sick and weak chickens often appear. Farmers should promptly select and eliminate these chickens, because these chickens are weakly susceptible to diseases and can be transmitted to healthy chickens. As these chickens cannot be slaughtered normally, it will also increase the amount of feed consumption and affect the feed conversion ratio of the flock.
In addition, in addition to the three-dimensional cage, especially the ground free-range and flat-breeding chickens, it is necessary to divide the group and increase the partition in a timely manner, not only to give the chickens space for activity, but also to prevent the activity space from being too large, affecting growth and growth.
3. Disease factors
The high chicken feed conversion ratio caused by the feed waste caused by diseases accounts for a large proportion in feeding. When healthy chickens and sick chickens eat the same amount of feed, healthy chickens will make full use of the feed, and the nutrients absorbed by the sick chickens are far from the body's needs, which will increase the adoption of Food intake, causing loss of feed. However, the proportion used to increase body weight is reduced, resulting in an increase in the final ratio of meat to meat.
4. Baby chick factor
In actual production, the quality of the baby chicks and their health also have a great influence on the feed conversion ratio in the future. The quality of the chicks is good, the flocks are healthy, they can be fully absorbed after eating the feed, the growth rate is fast, and the weight gain effect is also good. Conversely, if the quality of the chicks is poor, there are many weak chicks, and the gastrointestinal function is not fully developed, there will be slow growth and insignificant weight gain, and even some weak chicks will die because of some unfavorable factors, which will seriously affect the chicken broiler feed conversion ratio.
5. Chicken Feed nutrition factors
Nutritional factors are mainly manifested in feed during the breeding process, and high-quality feed is the most critical factor for reducing the feed conversion ratio. The feed quality mainly includes raw material quality, nutritional balance and processing technology.
(1) Raw material quality
Corn and soybean meal are the main energy and protein sources of feed. The quality of corn and soybean meal in different production areas are different, and the energy and protein provided are also different. Then manufacturers have differences when purchasing raw materials. Relatively speaking, large-scale enterprises have high requirements for feed quality and quality assurance because of the perfect testing equipment. Some small feed mills have relatively unstable product quality. This will cause the chickens to grow at different speeds and have a different feed conversion ratio.
(2) Degree of nutritional balance
High-quality feed not only has high raw material quality, but also nutritional balance has different nutrition standards for different stages. As long as the farmers in the farming process are raised in accordance with the divided stages, the chickens can have a good growth rate and gain weight. However, if the nutrition of the feed is not balanced, it will affect the growth of the flock and increase feed conversion ratio.
(3) Processing technology of broiler feed
If the same feed formula adopts different production techniques, the feed remuneration is also different, such as the size of the pellets, the degree of puffing, etc., which will eventually lead to different feed conversion ratio. The following is the recommended chicken feed processing process for you:

Raw material receiving--Cleaning--Grinding--Raw material pelleting--Batching--Mixing--Pelleting--Cooling--Crumbling--Liquid Adding & Coating--Packaging (The difference in raw materials and output will directly lead to different processing processes of pellets.You can rely on RICHI to get maximum fuel efficiency at minimum maintenance cost, to receive the most productivity. )
Capacity：1-100 tons per hour.
Final Product: Pellet feed.
Pellet Size：2.0-4.0 mm.
Batching System：Manual or Automatic.
Packing System: Manual or Automatic.
To ensure GMP cleaning is an important aspect. Different type of cleaner used for this purpose.
All transportations like bucket elevator, screw & chain conveyor etc. for conveying RM & Finished goods.
Raw materials need to be grinded as 225 m/microne perticle size by chicken feed crusher for different type of feed.
Different R/M are mixed here with additives, oil/fat, medicines, etc. Good chicken feed mixer ensure good quality.
Produce final chicken pellet feed. A good pellet means "A complete feed" and a good chicken feed pellet making machine can ensure that.
Extruded feeds are about 70-90° C. Chicken feed cooling machine bring down it at normal temperature (+4° max).
To ensure supply of quality and perfect size feed, screener plays a vital role. Uneven sizes screaned-out.
Ready chicken pellet feed need to be packed. It can be manual or automatic bagging depends on requirement.
