White meat chicken is a widely farmed poultry in modern agriculture. Due to its rapid growth and high meat content, it has become one of the important meat sources in people's daily diet. However, behind this high-efficiency growth lies a series of issues and challenges, from administration of growth hormone, animal welfare to food safety, etc., which have been widely discussed. Then let's take a look at the whole process of white meat chickens from egg hatching to birth, growth during breeding, and final slaughter.
Why do broilers grow so fast?
White-meat chickens, also known as instant chickens, chickens, as the name suggests, are meant to be able to grow up quickly. The reason why they can grow so fast is mainly because they have passed through thousands of generations.Artificial breeding and optimization of varieties, giving them a higher growth rate and muscle development as they grow. In addition, modern aquaculture has adoptedAdvanced feeding management, feed and nutritional formula, Under the combined effect of these factors, white meat chickens can gain weight rapidly in a short period of time and shorten the time to market.

1. Incubation process
- Choose high-quality eggs: Before the incubation process begins, the hatchery staff selects high-quality fertilized broiler eggs. These eggs must be of good shape, size and finish to ensure successful hatching.
- incubator incubation: After sifting the eggs, they are transferred to the incubator. The incubator can provide the right temperature, humidity and turnover speed to simulate the natural environment of the hen incubating eggs.
- Control temperature and humidity: The temperature and humidity in the incubator will affect the hatching success rate of the eggs. Generally speaking, the broiler hatching temperature is about37.5-38 degrees Celsius, humidity is around 60-70%.
- flip eggs: During the hatching process, the incubator will turn the eggs regularly, which helps the eggs to be heated evenly, and also prevents the embryos from sticking to the eggshell and affecting hatching.
- Incubation time: broilerThe incubation period is about 21 days. During this time, the incubator maintains a steady temperature, humidity, and turnover rate until the chicks are fully hatched.
2. Chick period
- Observation after hatching: Once the chicks have successfully hatched, they spend their first few hours in the hatchery. The hatchery's breeders will carefully observe these newborn chicks for the first round of screening.
- provide a warm environment: Since the body temperature regulation system of the chicks is not fully developed, a relatively warm environment is needed, so when the chicks are just bornThe temperature should be kept at 32~35℃, and then gradually cool down.
- proper nutrition:The brooding time of white broiler chickens is about 2 weeks. The feedlot provides high-quality feed suitable for the chicks to ensure that the chicks get the nutrients they need.
- Monitoring and Health Management: Breeders will closely monitor the health of the chicks and promptly address any possible health issues. These include preventing disease and managing possible conditions.
- transfer to farm: After the chick period, the chicks are transferred to the farm.
three,growth and fattening period
- high quality feed: During the growing and finishing period, broiler chickens need nutrient-rich feed to support their rapid growth. Trainers will provideHigh energy, high protein and high carbohydrate feed, which contains grains such as wheat and corn, beans, vitamins, minerals, etc., to meet the meat increasing demand of broilers.
- control feed supply: Breeders will control the feed supply and feeding frequency according to the growth rate and needs of the broiler chickens, so as to achieve the predetermined growth and meat increase goals.
- Monitor growing environment and broiler health: Proper temperature and ventilation ensure broiler health and reduce the risk of disease. At the same time, the breeders will regularly monitor the growth of the broilers, including indicators such as weight, appetite and growth rate, which help to ensure that the growth of the broilers meets the expected goals and detect any health problems in a timely manner.
4. Slaughtering, grading and marketing
- transportation: Broiler chickens are transported from the farm to the slaughterhouse.
- slaughter: Once at the slaughterhouse, the slaughterhouse useselectric shock or carbon dioxide gasStunning and rapid bloodletting are carried out in other ways to reduce the pain of broilers and conform to the spirit of humanity.
- Hairing and peeling: After slaughter, broilers are put into a depilling machine to remove feathers. In some cases, the skin is also removed to obtain naked chickens.
- Eviscerated: The broiler is next eviscerated, also known as evisceration. Internal organs including the heart, liver, intestines, etc. are removed and cleaned and sterilized.
- Inspection and Grading: During the slaughter process, broiler chickens are inspected to ensure quality and hygiene, and graded by size and weight for subsequent packaging and distribution.
- refrigeration: After slaughter, the broiler will enter the cold room to cool down to an appropriate temperature. This is to ensure the quality of the broiler and prevent the growth of bacteria.
- packaging and distribution: After refrigeration, broiler chickens are packaged and distributed to various sales channels such as supermarkets, restaurants and meat markets according to demand.
Are broilers injected with growth hormone?
Chickens grow fast mainly becauseLong-term selection and breeding work, not caused by injection of growth hormone. Chicken farmers achieve the effect of rapid growth of chickens by selecting high-growth broiler breeds, providing nutrient-rich feed, and managing the breeding environment. These methods ensure that the chickens get enough nutrition, so that the white meat chickens can grow to the weight and size of the slaughter market within 40 days, so there is no need to inject growth hormones or use drugs for a long time, which is not in line with the cost of farming .
Chicken May Contain Antibiotic Residues, Better Eat Less? Is It True?
The use of antibiotics in broiler rearing isTo prevent and treat disease, Improve chicken health and growth efficiency. When broiler chickens are treated with antibiotics, a corresponding withdrawal period will be passed, and it will be ensured that the antibiotics have been completely metabolized or reduced to safe levels at the time of slaughter. However, excessive and inappropriate use of antibiotics may lead to resistance problems, leaving antibiotics in chicken and possibly detected in food.
Most countries have strict food safety standards and regulatory agencies responsible for monitoring, regularly sampling and testing the level of antibiotic residues in broiler chickens to ensure the safety of chicken meat. Therefore, consumers can choose reliable brands or sources to ensure that the broilers they eat meet national food safety standards.
