La fase de crecimiento del pollo de engorde es un momento especial en la vida de un pollo. Ocurre entre los 11 y 24 días de edad. Durante estas dos semanas, los pollitos no solo se hacen más grandes, sino que están construyendo músculo a una velocidad increíble. Este es el período en el que su cuerpo se enfoca en desarrollar carne de pechuga fuerte y masa muscular en general. Piense en ello como su mayor estirón de crecimiento. Darles la comida exactamente correcta durante esta ventana los prepara para el éxito por el resto de sus vidas. Una nutrición adecuada aquí conduce a un ave más sana y un mejor rendimiento de la carne más adelante.
Amino acids are the small building blocks that make up protein. Protein, in turn, builds muscle. During the grower phase, a chick's body is like a busy construction site, building muscle very quickly. To do this, it needs a constant and correct supply of all the right amino acid "bricks." If even one type of brick is missing, the whole construction process slows down. This is why a precise amino acid profile for poultry is so important. It ensures the chick has everything it needs to build muscle efficiently without wasting energy.
Lysine is the most important amino acid in the grower phase. We use it as the reference point to balance all the others. For the best growth, a broiler's diet should have about 1.18% digestible lysine. This level helps the chick build the maximum amount of muscle. As a nutritionist, I've seen firsthand that if the lysine level is off, the entire growth potential of the flock is limited. Products like high-purity L-Lysine HCl 98.5% are vital for hitting this exact target in commercial feeds.
Methionine is another crucial amino acid. It is a sulfur amino acid, which helps not only with building protein but also with keeping the bird's immune system strong. The feed should contain about 0.51% digestible methionine. We often look at its ratio to lysine, which should be around 43%. This balance ensures that the protein synthesis process runs smoothly. Using a reliable source like DL-Methionine 99% gives feed producers confidence that this critical nutrient is available for the chick to use for both growth and health.
Threonine has two important jobs. It helps build muscle protein and also helps maintain a healthy gut. The gut lining uses a lot of threonine to create a protective mucus layer. This is especially important during the grower phase when chicks eat a lot, which can stress their digestive system. The ideal level of digestible threonine is around 0.79%, or about 67% of the lysine level. Adding a quality L-Threonine product ensures the birds can handle their feed well while still having enough of this amino acid left over for muscle development.
While lysine, methionine, and threonine are the top three, other amino acids like valine and arginine are also very important. Valine becomes more critical as the bird grows, helping with muscle development and energy. Arginine is key for growth and supporting the immune system. The right feed formulation will balance these and other amino acids feed additives. The goal is to provide a complete profile where no single amino acid runs out, which would stop the growth process. Each one has a specific role to play in the chick's rapid development.
Para simplificar las cosas, los nutricionistas utilizan una matriz, o una tabla, para mostrar el equilibrio perfecto de aminoácidos en relación con la lisina. Esto asegura que todos los "componentes básicos" se suministren en las proporciones correctas para un rápido crecimiento muscular.
| Aminoácido | % de la Dieta | Relación con la Lisina |
|---|---|---|
| Lisina | 1.18 | 100 |
| Metionina + Cisteína | 0.92 | 78 |
| Metionina | 0.51 | 43 |
| Treonina | 0.79 | 67 |
| Valina | 0.91 | 77 |
| Arginina | 1.27 | 108 |
| Triptófano | 0.19 | 16 |
This table is the core of the broiler grower matrix. Following it helps maximize the genetic potential of the birds. Ingredients like Feed Yeast can also contribute valuable proteins and nutrients to the overall diet.
The perfect amino acid matrix isn't static. Two big factors can change it: energy and genetics. If you change the energy level in the feed, you must also adjust the amino acid levels to keep the ratio correct. More energy requires more amino acids to support growth. Also, modern chickens are bred to grow faster and more efficiently than ever. These genetic improvements mean they have a higher demand for amino acids to build their bigger muscles. This is why feed formulations must be updated regularly to match the needs of the specific chickens being raised, often using protein sources like Soybean Meal.
A chicken's environment also affects its nutritional needs. During hot weather, chickens tend to eat less. However, their need for certain amino acids, like arginine, can actually go up to help them cope with heat stress. An expert tip I often share is to slightly increase the arginine-to-lysine ratio during summer. Similarly, if birds are facing a health challenge, their immune system will use up more amino acids. This means less is available for growth. Providing the right China feed additives can support them through these stressful periods.
The broiler grower matrix only works if the amino acids you add are high quality. Pure, synthetic amino acids are 100% available for the chicken to use, unlike amino acids bound up in other feed ingredients that need to be digested first. This purity and consistency are vital. When you use a product, you need to be sure the bird is getting the exact amount stated on the label. This is why working with a trusted supplier who provides a Certificate of Analysis (COA) is so important for creating effective and reliable poultry feed. Products like Allicin can also support overall health.
¿Cuál es el aminoácido más importante para los criadores de pollos de engorde? La lisina se considera el aminoácido más importante, o "limitante primario". Se utiliza como referencia para equilibrar todos los demás aminoácidos en el alimento.
¿Por qué es tan importante el período de 11 a 24 días? Este período es cuando los pollitos de engorde experimentan su tasa más rápida de crecimiento muscular. Una nutrición adecuada durante estos 14 días tiene un gran impacto en el peso final del ave y el rendimiento de la carne.
¿El clima cálido cambia los requisitos de alimentación? Sí. En climas cálidos, las gallinas a menudo comen menos, por lo que es posible que el alimento deba estar más concentrado con nutrientes. La necesidad de ciertos aminoácidos, como la arginina, también puede aumentar para ayudar a las aves a sobrellevar el estrés por calor.
¿Qué sucede si la mezcla de aminoácidos es incorrecta? Una mezcla incorrecta de aminoácidos conduce a un crecimiento deficiente, un menor rendimiento de carne de pechuga y una mayor tasa de conversión alimenticia, lo que significa que cuesta más criar al ave. También puede provocar problemas de salud.
