Can foodies still eat chicken with peace of mind?
There are various sensational rumors circulating among the people, such as "the rapid growth of broiler chickens is stimulated by hormones" and "each chicken has 8 wings". These people with ulterior motives spread the rumors widely to achieve their unspeakable goals, and even unscrupulous media have coined the term "fast-growing chickens". Why do modern broiler chickens grow so fast? Now, let's learn more about modern broiler chickens together. Foodie owners, you can eat chicken with peace of mind!

Genetic selection and excellent breeding
People have a misconception about broiler chickens: they are usually raised for more than six months to mature before being sold, while white feathered broiler chickens can be sold in just over 40 days and weigh around 2.5 kilograms. Many consumers do not understand this, but in fact, this is the result of the continuous efforts of breeding experts from around the world for a hundred years.
The development of scientific breeding in the past century has formed a scientific breeding system. Breeding experts need to select the core breeding population from the gene bank, which has undergone multiple generations of cultivation from great grandparents, ancestors, and parents, before it can become a commercial broiler chicken. In the breeding industry, the world's white feathered broiler breeding experts have annual breeding goals every year.
Just as a person's lifespan can last for a hundred years, the period of rapid growth is during infancy and early childhood. In fact, white feathered broiler chickens have not reached sexual maturity when they are slaughtered for more than 40 days and are still in their infancy stage.The industry chooses to slaughter white feathered broiler chickens for more than 40 days because at this time, the protein content is high, the fat content is low, the meat is tender and easily absorbed by the human body, which is beneficial to human health! The products (such as wings, legs, and breast meat) have uniform specifications, making them convenient for cooking, processing, and consumption. At the same time, the feed return rate at this stage is high, the feed to meat ratio is low, and the economic benefits are good.
Compared to the current free range chicken breeds raised by farmers, due to the lack of genes for rapid growth, the growth rate of free range chickens is significantly slower than that of modern broiler chickens, which is considered very normal. It can be said that the key to modern broiler chickens growing so fast is that they have breed genes that promote fast growth and high feed conversion rates.

Nutritious feed, scientific feeding
Chickens have a much higher feed utilization efficiency than pigs, cows, and sheep. Chicken meat is a cheap source of animal protein, which is also an important reason for the rapid development of China's broiler industry.
In the long-term practice of raising broiler chickens, it has been found that in order to fully utilize the genetic genes of fast growth rate and high feed conversion rate, it is necessary to feed broiler chickens with high-energy and high protein complete feed. Modern broiler nutrition experts scientifically ratio feed materials such as corn, soybean meal, oil, minerals, and trace elements based on the characteristics and nutritional requirements of different stages of broiler growth and development, to produce nutritionally balanced full price feed that meets the nutritional requirements of broiler chickens at different stages of growth and development. It is this nutritionally balanced, high-energy, and high protein complete feed that provides the material basis for the healthy and rapid growth of broiler chickens, allowing the genes with fast growth rate and high feed conversion rate in broiler chickens to unleash their genetic potential.Modern broiler chickens grow faster, largely due to the improvement of feed nutrition levels and feeding conditions. Traditional rural chicken farming is fed with single raw materials such as rice, corn, and wheat bran, which are nutritionally deficient and affect growth.There have been significant changes in the growth rate of broiler chickens in different eras. In 1934, broiler chickens took 95 days to enter the market, and by 2014, they could enter the market in 42 days, with their weight increasing by more than twice.

Environmental control, developmental assurance
The body temperature of newborn chicks is between 39.4 ℃ and 41.1 ℃, with less subcutaneous fat, relatively less hair, poor insulation ability, and poor ability to use energy to produce temperature. After 28 days of age, broiler chickens begin to grow their feathers fully, and their temperature regulation mechanism begins to improve, gradually adapting to the external environment. At the same time, due to the rapid growth genes of broiler chickens and the feeding of nutritionally balanced, high-energy, high protein, whole price feed, the metabolic rate of broiler chickens themselves is particularly fast, and they have particularly high requirements for the temperature, humidity, and air quality of the feeding environment. Meeting these environmental control requirements for broiler chickens is essential for their healthy and rapid growth and development.
1. Temperature:The ambient temperature for 1-day-old chicks should be controlled at 34-35 ℃. At 7 days of age, the ambient temperature gradually decreases to 32 ℃. In the future, as the age of the chicks increases, the temperature will decrease by 2-3 ℃ per week, and by the age of 35 days, the temperature in the chicken coop will be controlled at 21 ℃. At the same time, when lowering the temperature of the chicken coop environment, broiler feeding experts gradually reduce the temperature of the chicken coop environment. The daily temperature difference in the chicken coop should not exceed 1 ℃ to avoid causing cold stress to the chickens.
2. Humidity:Control the humidity of broiler chickens at 60% -65% for one week. In the future, as broiler chickens grow up, the humidity gradually decreases to 45% -65%.
3. Ventilation:The rapid growth rate and vigorous metabolism of broiler chickens require at least 0.5-0.6 cfm/kg of ventilation. The normal growth and development of broiler chickens require not only air quality, but also air quality. Broiler feeding experts use automatic ventilation equipment to control the ventilation time of the chicken coop, ensuring that the oxygen content in the air inside the coop is greater than 19.6%, the carbon dioxide concentration is less than 0.3%, the ammonia and carbon monoxide concentrations are less than 10ppm, and the dust is less than 3.4 mg/m3.

Hygiene and epidemic prevention, stay away from diseases
The hygiene and epidemic prevention measures for broiler chickens are important factors in ensuring their rapid growth and development. Modern broiler farms are established in a closed and fully in and out feeding and management mode far away from people's production and living areas. They do a good job in disease source isolation, disinfection of goods and vehicles, personnel entry and exit management, implementation of chicken herd immunization plans, scientific medication and health monitoring of chicken flocks, etc., to ensure the healthy growth of broiler chickens away from diseases and accelerate their growth rate.

Science and technology, feeding and management
1. Increase the body weight of broiler chickens at 7 days of age:Research has found that for every 1g difference in body weight of broiler chickens at 7 days of age, there will be a 6.7g difference in slaughter weight. To increase the 7-day-old body weight of broiler chickens, we feed them within 6 hours after hatching to stimulate digestive tract development and cultivate good appetite. The 7-day-old body weight of broiler chickens indicates good growth and development during the hatching stage, laying a solid foundation for future growth and development.
2. Lighting control technology:After 7 days of age, the growth rate of muscles, bones, and feathers in broiler chickens significantly accelerates, causing various organs in the body to remain in a state of stress, especially the heart and lung function, which often cannot keep up with the needs of metabolism. At this time, it is easy to develop sudden death syndrome and ascites syndrome unique to broiler chickens. Compared to rapidly growing muscles, the development of bones in broiler chickens appears slower, which can lead to leg problems. Reduce the feed intake of chicks by decreasing the intensity and duration of light exposure. When the feed intake of broiler chickens decreases, their growth rate slows down, resulting in a more balanced development of muscle, bone, and cardiovascular systems, and an increase in their survival rate.
3. Install automated feeding and drinking water systems in modern broiler farmsReducing water waste, ensuring feed and drinking water hygiene, and reducing the occurrence of chicken diseases. The widespread use of this automatic feeding system has greatly improved the labor efficiency of broiler feeding, and the large-scale production of broiler chickens has developed rapidly.

Refuting rumors, safe and reassuring
1. Is the rapid growth of broiler chickens stimulated by hormones?
Why do modern broiler chickens grow faster? This mainly depends on the variety. Modern white feathered broiler chickens (also known as fast large broiler chickens) are based on the relatively fast growing roasted Nis chickens in the early stages. Through generations of breeding by scientists, slow growing families are eliminated, and fast growing families are left for breeding, resulting in faster and faster growth of offspring. Traditional rural raised chickens, on the other hand, belong to dual-purpose meat and egg breeds and have a slow growth rate. They have not been specifically selected and bred, and their growth rate is far slower than modern broiler chickens.
2. Will feed additives promote growth?
How to meet the rapid growth of chickens? We need to provide nutritious feed.Chicken feed mainly includes corn, soybean meal (residue from soybean oil extraction), salt, marble powder, and feed additives (mainly supplements vitamins, trace elements, phosphorus, and amino acids, which are also commonly supplemented by humans), which can meet the 41 nutrient requirements for chicken growth and development. In addition, some feed drug additives are added to prevent and treat chicken diseases. But it is not added to the feed one week before listing, which provides sufficient time for the drug to be excreted from the body and avoids drug residue. be careful!!! Our country's laws explicitly prohibit the addition of hormones, so there is no such thing as feed additives to promote growth.
3. Do broiler chickens eat and sleep, wake up and eat, but have no activity space?
Modern broiler chickens grow quickly, and although they have less exercise, the designed activity space in the chicken coop is large, and the movement of broiler chickens is not restricted. Modern chicken coops can achieve automatic control of temperature, humidity, and ventilation, ensuring that toxic and harmful gases such as carbon dioxide and ammonia do not exceed standard values. The comfort level of the chicken living environment is even better than that of humans.
4. KFC chicken wings and chickens with six wings?
So far, scientists have not cultivated chickens with six wings. Some chickens may have an extra wing, which is a freak phenomenon, just like conjoined individuals and two headed animals. The probability of occurrence is very low and cannot be inherited. A normal chicken can only grow two wings.
5. Is chicken tip, chicken butt, chicken wings, chicken neck safe to eat?
The tip or tail of a chicken is nothing special. Above the anus of chickens is the immune sac, which will shrink as it grows.To prevent the growth of chicken pox, laying hens need to be vaccinated by puncturing the avascular area (triangular area) of young chicken wings, just like humans are vaccinated with cowpox, which is absorbed into the body through the bloodstream. Broiler chickens have a short growth period and are not vaccinated with chicken pox. Injecting vaccines into the necks of chicks is a form of chicken immunity, which can be well absorbed into the body under normal circumstances. As long as there are no residual vaccines in the necks of chicks, they can be eaten. In addition, areas without large blood vessels and nerves such as chicken breasts and legs are often the sites for vaccination, just like when a person injects into their buttocks.
6. Chicken and flavor?
Modern broiler chickens have a fast growth rate, relatively less fat deposition in the meat, fewer flavor compounds, tender and easy to bite, suitable for frying and fast food. Native chickens grow slowly, have more fat deposits in their meat, and have more flavor compounds, but their meat quality is relatively dry.
At the end, a viral video is sent to everyone to watch on CCTV. The chicken that has been on the table for 42 days is fresh and delicious, healthy and safe. ▼▼▼
