Egg laying in the battery cage for layers will also bring economic benefits from the production of eggs. When selling eggs, the weight is calculated according to the weight. The egg weight is directly related to the economic benefit of the culture, and the egg weight is affected by the cultured species and culture. Mode, environment, nutritional level and other factors.

The effect of protein on the weight of eggs, protein accounts for 10% of the total weight of eggs, and the total weight of duck eggs is more than 12%. There must be a certain level of protein in the diet to supplement essential amino acids and provide sufficient nitrogen source for the synthesis of non-essential amino acids. 

The effect of methionine on egg weight The effect of methionine on the weight of eggs in the layer chicken cage , methionine is involved in the synthesis of protein in the body, and is also an important methyl donor. It is often the first limiting amino acid in avian corn-soybean diet. An important nutrient factor that affects egg weight. For high-yielding laying hens, methionine levels can significantly affect egg weight. Energy is the driving force behind the metabolism of poultry. Without energy, the entire metabolic process of poultry is affected. There are some inconsistencies in the effect of energy on the weight of poultry eggs. As the energy level increases, the egg weight also increases significantly.

Linoleic acid is an essential fatty acid in poultry. As early as 1974, it was confirmed that linoleic acid is an important factor affecting the maximum egg weight. Linoleic acid can increase the synthesis ability of liver lipoprotein
lipase, increase the development of oocytes, and increase egg weight by increasing the weight of egg yolk. However, there is some controversy about the need for linoleic acid to meet the maximum egg weight. Most studies have shown that 1.0% linoleic acid content can basically meet the needs of maximum egg weight, and the content of sub-oil in the diet is less than 0.8%. Acid may reduce egg weight. The difference in the study of linoleic acid requirements may come from the storage of linoleic acid in laying hens. Egg yolks can meet their needs by using their own stored linoleic acid. For example, linoleic acid storage during the breeding phase can reduce the initial stage of production. The need for linoleic acid in the stage, while the need for linoleic acid in the late stage of egg production increases.

Because the demand for broiler chickens is getting bigger and bigger in the society, some people have seen business opportunities and started to raise broilers. The chicken meat is rich in protein and the meat is delicious, which is very popular among people. So what kind of production advantages does it have for farmers to use broiler battery cages to raise broilers? The authors refer to the experience of poultry equipment manufacturers and now share them with farmers.

1. Early growth of broilers is very fast. Generally, the weight of the chicks is 40 grams. After 56 days of feeding, the body weight is close to 2000 grams, which is 50 times the weight of the shell. Some people like to compare the early growth rate of broilers is "100 meters race", feeding management techniques must be appropriate, otherwise it is difficult to make up.

2. Short production cycle and fast turnover. Domestic broilers usually reach the market standard at 8 weeks of age and weigh more than 1.5 kg. After each batch, they should be cleaned, disinfected and fumigated for 10-14 days. A batch of pigs is raised in about 10 weeks. If the chicks are supplied in time, 5 batches can be produced in one year.

3. The feed utilization efficiency is high. The domestic conversion rate of broiler feed is 2.5-2.8:1, which is close to 2:1 in many countries around the world. Broilers shorten the developmental stage by increasing early growth rate and are listed at 7 weeks of age to further increase feed conversion.

4. Chicken cages have high stocking density and high utilization rate of chicken houses. Compared with laying hens, broilers are quiet and not moving. In addition to eating and drinking water, they rarely fight, especially in the late fattening period, due to the rapid increase in body weight, the amount of activity is greatly reduced. Although the density increases with the growth of the chicken, the density of the air in the house is small, and the breeding density can be increased as long as there is suitable ventilation. Generally, the density of light chicken cages is 24-32/m2, and that of medium chickens is 20-24/m2.

5. Suitable for automatic poultry breeding equipment to save labor. Feeding broiler chickens is caged, with high density, chickens are in cages, feeding, picking eggs, clearing dung, epidemic prevention, etc., and automated production lines can improve labor efficiency.

6. Improve feed efficiency by 5-10% and reduce total cost by 3-7%.

7. It is not easy to get coccidiosis, which can save a lot of expenses.
