Modern laying hens are very productive. They lay many more eggs than hens did in the past. Because they work so hard, they need special food to stay healthy and productive. The right food gives them the building blocks to make high-quality eggs every day. Hens use the protein in their feed for two things: to keep their bodies healthy and to make egg yolks and whites. Most of the protein they eat goes directly into making eggs. This is why getting the right mix of animal nutrition supplements is so important for a successful farm.
Lysine is the main amino acid we use to measure a hen's diet. Think of it as the foundation. All other amino acid needs are measured against it. A laying hen needs between 720 and 917 milligrams of lysine each day. Hens that are at their peak egg-laying age need the higher amount to produce the most eggs. To get the best results, you want to focus on egg mass, which is the total weight of eggs produced. This requires more L-Lysine HCL 98.5% than just keeping egg numbers steady.
Methionine is usually the first amino acid that is missing in a standard corn and soybean meal diet. It is a critical part of the essential amino acids for animal nutrition. A hen needs about 415 milligrams of digestible methionine per day. This nutrient does more than just help with egg numbers. It is also very important for making strong eggshells. Good methionine levels help the hen use calcium correctly to build a strong, thick shell. Without enough DL-Methionine 99%, you might see more cracked or weak eggs, which costs money.
Total Sulfur Amino Acids, or TSAA, is the total amount of two amino acids: methionine and cysteine. Using a TSAA value gives you more options when mixing feed. This can help lower costs. Cysteine can do some of methionine's job, but it can't replace it completely. Hens need a TSAA level that is about 85% to 91% of their lysine intake. Studies show that hens fed the full amount of TSAA lay more eggs and have a higher egg mass. This is especially true when hens are stressed, for example, during hot weather. Having the right amino acids feed additives is key in these situations.
A hen's nutritional needs change as she gets older. During her peak production phase, from about 20 to 44 weeks old, she needs the most nutrients. This is when she lays the most eggs. After 44 weeks, her production naturally slows down a little. You can slightly lower the amino acid levels in her feed during this post-peak phase. As an expert, I always advise farmers to adjust feed for different age groups. It's a simple way to manage costs without hurting egg production. A good poultry feed formulation using yeast can also support gut health through all life stages.
Eggshell quality is a major factor for profit. Weak shells lead to broken eggs and lost income. Amino acids play a big part in how strong a shell is. When hens lay very large eggs, the shells often get thinner. You can manage this by adjusting the amino acid balance. For example, lowering the TSAA-to-lysine ratio can help control egg size and keep shells thick. Methionine helps the hen's body use calcium to build the shell. Proper levels of minerals like Dicalcium Phosphate are also essential, as explained in this guide to Dicalcium Phosphate.
Lograr el equilibrio adecuado de aminoácidos es crucial. La lisina es el punto de referencia, establecida al 100%. Todos los demás aminoácidos esenciales deben proporcionarse en una proporción específica con respecto a la lisina para obtener los mejores resultados.
| Aminoácido | Relación Ideal con Lisina |
|---|---|
| Lisina | 100% |
| Metionina | 46% - 50% |
| TSAA | 85% - 91% |
| Treonina | 67% - 77% |
| Triptófano | 22% |
| Valina | 83% - 88% |
| Isoleucina | 86% - 90% |
Following these ratios ensures that there are no limiting amino acids holding back production. Products like L-Threonine help you meet these precise targets.
Using pure, crystalline amino acids is smart for business and the environment. When you add specific amino acids, you don't need to use as much high-protein feed like Soybean Meal. This can lower your feed costs. It also reduces waste. When hens get the exact amino acids they need, less nitrogen is passed out in their manure. For every 1% you reduce crude protein in feed by using targeted amino acids, you cut nitrogen waste by 10%. This is a huge benefit for the environment. Using various feed protein sources becomes more efficient.
When you mix feed, always use digestible amino acid values. The total amount of an amino acid in an ingredient doesn't matter if the hen can't absorb it. I once visited a farm with low egg production. Their feed test showed high total protein, but the digestible methionine was very low. We fixed the problem by adding a quality DL-Methionine supplement. Production was back to normal in just a few weeks. Always check your common feed ingredients and monitor your flock's egg mass and shell quality to fine-tune your feed program.
P1: ¿Cuánta lisina necesita una gallina ponedora cada día? Una gallina ponedora necesita entre 720 y 917 miligramos de lisina digestible por día, dependiendo de su edad y nivel de producción.
P2: ¿Por qué es tan importante la metionina para las cáscaras de huevo? La metionina ayuda al cuerpo de la gallina a transportar y depositar el calcio correctamente al formar la cáscara de un huevo. Esto conduce a cáscaras más fuertes, más gruesas y menos grietas.
Q3: Can I just add more protein to the feed? Adding more crude protein is not efficient. It's better to use specific amino acids to meet the hen's exact needs. This approach saves money and reduces environmental waste.
P4: ¿Qué es TSAA? TSAA significa Aminoácidos Totales de Azufre (Total Sulfur Amino Acids). Es el total combinado de metionina y cisteína. El uso de un valor TSAA en la formulación de alimentos proporciona más flexibilidad y puede ser más rentable.
P5: ¿Las gallinas más viejas necesitan el mismo alimento que las gallinas más jóvenes? No. Las gallinas en su período máximo de puesta (20-44 semanas) tienen mayores necesidades nutricionales que las gallinas más viejas (después de las 44 semanas). Ajustar el alimento a su edad puede mejorar la eficiencia.
