Compensatory growth in broiler chickens

Compensatory growth in broilers is a fascinating biological phenomenon and of great importance in poultry production, it refers to the ability of these animals to accelerate their growth rate after having experienced a period of restriction or delay in their development. Compensatory growth is the rapid increase in the growth rate, compared to age, that occurs when chickens are properly fed after a period of nutritional restriction, in other words, it is the ability of chickens to regain lost growth.

According to what was reported by González (1990), during the restriction, the metabolism of the chicken adapts to conserve energy, when feeding is restored, the chicken uses nutrients more efficiently, resulting in accelerated growth. The knowledge of compensatory growth allows producers to adjust feeding programs to optimize yield, in situations of feed shortage or management problems, a controlled restriction can be implemented followed by a recovery phase. Compensatory growth can improve feed efficiency, as chickens use nutrients more efficiently during recovery.

Among the factors that influence compensatory growth are the duration and severity of the restriction, short and moderate restrictions tend to generate a better compensatory response, prolonged or severe restrictions can damage the growth potential. The age of the chicken is another factor, since younger chickens usually have a greater compensatory growth capacity. Nutrition during recovery is crucial when providing a balanced, high-quality diet during the recovery period to maximize compensatory growth. Also the genetic lines of broilers have a greater compensatory growth capacity than others.

Applying this type of feeding strategies has implications in poultry production, for example in meat quality, it is important to properly manage compensatory growth to avoid negative effects on meat quality. That is why the successful implementation of compensatory growth implies a balance between maximizing yield and ensuring animal welfare, constant monitoring and precise adjustments in feeding programs are required to avoid negative consequences as we said above on the quality of meat and the health of birds.

It is important to improve this type of strategies to carry out continuous research of the process since it is fundamental to better understand the mechanisms of compensatory growth and develop more efficient management strategies, this of course includes the evaluation of different genetic lines, the optimization of feeding programs and the exploration of new technologies.

Dear readers, it is important to highlight that, although compensatory growth can be very useful, food restriction should not be abused, since this could have negative consequences for the welfare of the animal, according to some specialists it is always recommended that any management of this type be supervised by experts in the field. In conclusion, compensatory growth offers an opportunity to improve poultry productivity, but its responsible and evidence-based application is essential to achieve optimal results.
