Nutrition is an integral part of broiler fattening, and is even considered a key element in the sprint. Therefore, when choosing bran, livestock farmers should pay attention to choose products with nutritional criteria of at least 2900 kcal/kg, minimum protein: 20%.

In order for chickens to gain weight the best, farmers should let chickens eat freely regardless of day and night, adding corn in the diet to increase meat quality.

In a day, the breeder can feed the chickens about 4-6 times, each time adding new food, it is necessary to sieve the old feed to remove all impurities and feces mixed with the feed. In the diet should add green vegetables to increase fiber.

4 main reasons why chickens grow poorly and keep growing

Poor genetic quality

Genetic traits or genetic quality play an important role in the growth performance of broilers. For chickens that grow fast or slow, both pass on genetic traits to the next generation. So when farmers buy chicks from poor quality parents, the chicks will have poor performance, they will not grow as expected or will take longer to grow and develop. Some individuals even carry pathogens that pose a risk of disease outbreaks for the whole herd.

Poor quality food not enough nutrition

The quality of feed, especially the stage of chicks, determines their growth ability. For example, using burnt corn kernels, baby corn or soybeans in broiler diets (broiler or finishing stage) will reduce the composition of core nutrients in the feed, such as: metabolic energy and crude protein.

Other effects of using this type of feed are the loss of essential nutrients, making the animals unable to use them and causing severe malnutrition. The result leads to underdeveloped flocks and increased mortality.

In addition, feed with high mycotoxin content or feed containing intestinal irritants will damage intestinal villi, affecting the ability to absorb nutrients of chickens, increasing FCR. Along with that, feeding chickens less than the standard will not ensure adequate nutrition for development leading to slow growth and low body weight.

The density of raising chickens is too crowded

The overcrowding of chickens on the one hand makes chickens grow poorly, on the other hand increases the feed conversion ratio (FCR) and increases mortality.

Raising more than the standard number of chickens increases competition for food, creating conditions for larger chickens to compete with each other and preventing others from eating food or drinking water. This results in the chicken eating less and possibly going hungry.

In addition to recording poorer body weight, a high mortality rate can also be noted in this regard.

Disease pressure and breeding habits

When chickens get sick, it will reduce their appetite, disrupt metabolism and other important functions of the body, along with the abuse of antibiotics in disease prevention and treatment, leading to underdevelopment and increased mortality. death rate.

  • It is necessary to change the habit of having a new disease to cure or close to the selling stage to focus on promoting. There should be an active disease prevention process, focusing on controlling gastrointestinal diseases (in fact, about 70% of immune cells reside along the digestive tract), limiting or not using antibiotics (especially high concentrations of antibiotics).
  • Implement vaccination against disease for chickens according to epidemiology. Ensure hygiene and disinfection of the barn to prevent pathogens from entering the barn.
