How to choose feed for raising chickens with automatic chicken raising equipment? The trend of modern chicken farming is an intensive farming model. Because the use of automatic chicken raising equipment can provide a comfortable growing environment for chickens. Make the flock grow and develop in a good environment. So what kind of feed is good for raising chickens? The automatic chicken raising equipment manufacturer will briefly introduce it.
The growth of laying hens can be divided into: chicks, rearing period, laying period, middle laying period and late laying period. The main points of feed adjustment at each stage are as follows:
1. Chicks: Farmers generally call 0-6 weeks old laying hens the brooding period. The obtained feed nutrients are mainly used for the rapid growth of muscles and bones. However, the digestive system is not well developed, and the feed intake is small. At the same time, the gizzard has poor ability to grind feed. Therefore, chicks have higher nutritional requirements. Feeds with high energy, high protein, low fiber content are required. And to supplement higher levels of minerals and vitamins. Raw materials such as corn, fish meal and soybean meal can be used when designing the formula.
2. Raised laying hens: 7-18 weeks of age for laying hens is the breeding period. At this stage, the growth and development of chickens are vigorous, and the weight growth rate is relatively stable. Digestive organs mature gradually, and bones grow faster than muscles. The requirements for nutrients such as energy and protein are relatively low. Some raw materials with high crude fiber such as bran, grass meal, etc. can be used to reduce the cost of feed. Late rearing is to limit weight gain. Farmers can choose to use bran, etc. to dilute the nutrient concentration of the feed. Farmers from 18 weeks of age to the start of production can choose calcium raw materials with relatively high concentrations for feeding to speed up the reserve of bone calcium.
3. Laying hens: The laying hens are in the laying period from 19 weeks of age to elimination. In the early stage of laying, the laying hens are generally at the age of 40 weeks after laying eggs or when the laying rate is from 5% to 70%. The requirement of crude protein for chickens increases with the increase of egg production rate. In addition, the formation of egg shells requires a large amount of calcium, so the demand for calcium increases. Nutritional indicators such as methionine, vitamins, and trace elements should also be appropriately increased to ensure adequate supply of nutrients, so as to ensure and prolong the peak laying period of laying hens, give full play to their production performance, and improve economic benefits for farmers. Use corn gluten meal and other fine feed ingredients to avoid affecting feeding.
In the mid-laying period, the laying hens are generally 40-60 weeks old or after the peak period when the laying rate is 80%-90%. The weight of laying hens at this stage generally does not increase. After the peak period, the laying rate of laying hens gradually increases. Decline, so the nutrition for the feed is lower than the peak. However, due to the increase in egg weight, farmers should not reduce the crude protein level in the feed too quickly, and should reduce the protein level slowly.
The late laying period is after 60 weeks of age or the laying rate drops below 70%, and the laying rate during this period continues to decline. Due to the increase of chicken age, the ability to digest and absorb nutrients in the feed decreases, and the quality of eggshells deteriorates. Therefore, farmers should appropriately increase the amount of mineral feed when adjusting the feed, which can improve the calcium level. In the later stage of egg production, with the decline of egg production, the energy requirements of laying hens are correspondingly reduced, and the energy level cannot be increased at will, so as not to make the chicken fatter and affect the production performance.
The above are the main points of feed adjustment for laying hens at different stages in the process of raising chickens and laying hens as described by the automatic chicken raising equipment manufacturers. I hope the above descriptions can help all farmers.
