Dietary Supplementation of Increasing Levels of DLMethionine and L-Lysine in Hypoproteic Diets for Laying Hens Improves Productivity and Egg Quality

| description | To evaluate the effect of dietary supplementation of DL-methionine and L-lysine in hypoprotein diets on productivity and egg quality, a total of 240 White Leghorn laying hens (Hybrid L-33) of 26 weeks during laying peak period were placed for 49 days, according to completely randomized design with four treatments and 10 repetitions. Dietary treatments consisted of a control diet (no amino acid supplementation) (T0) and supplementation of 0.03% DL-Met and 0.04% L-Lys (T1), 0.06% DL-Met and 0.08% L-Lys (T2) and 0.09% DL-Met and 0.12% L-Lys (T3). At 26 and 33 weeks of age, 30 eggs per treatment were collected to determine internal and external egg quality parameters.The experiment diets did not affect the viability and feed intake. Supplementation of essential amino acids, especially the T3 improved egg weight (54.30 to 58.30 g), laying rate (76.89 to 85.45%) and mass conversion (2.52 to 2.11 kg/kg) (P&lt,0.05). At 33 week, the albumin height (7.21 to 8.23 mm), Haugh units (86.70 to 91.15) (P&lt,0.05) and shell surface (67.10 to 69.20 cm2) increased by the effect of supplementation of DL-Met and L-Lys. The results allow recommending the dietary supplementation of 0.09% DL-Met and 0.12% L-Lys in hypoprotein diets to improve productivity and egg quality in laying hens. |

Para evaluar el efecto de la suplementación dietética de DL—metionina y L-lisina en dietas hipoproteicas sobre producción y calidad del huevo, un total ole 240 gallinas ponedoras White Leghorn (Hibrido L-33) de 26 semanas durante el pleno pico de puesta, se ubicaron durante 49 dias, según diseño completamente aleatorizado con cuatro tratamientos y 10 repeticiones. Los tratamientos consistieron en un control (sin suplementación de aminoácidos) (T0) y la suplementación de DL—Met 0.03: L—Lys 0.04 % (T1); DL-Met 0.06: L-Lys 0.08 % (T2) y DL-Met 0.09; L-Lys 0.12 % (T3). A las 26 y 33 semanas de edad, se recolectaron 30 huevos por tratamientos para determinar los indicadores de calidad externa e interna del huevo. Las dietas experimentales no afectaron la viabilidad y el consumo de alimento. La suplementación dietética de los aminoácidos esenciales, sobre todo el T3 mejoro el peso del huevo (50.3 a 54.3 g), intensidad de puesta (46.89 a 55.45%) y la conversión masal (3.49 a 4.46 kg/kg) (P<0.05). En la semana 33, la altura de la clara densa (7.21 a 8.23 mm), unidades Haugh (87.70 a 92.15) (P<0.05) y Ia superficie de Ia cáscara (55.24 a 59.84 cm2) mejoraron por efecto de la suplementación de DL—Met y L-Lys. Los resultados obtenidos permiten recomendar Ia suplementación de dietética de DL-Met 0.09 y L—Lys 0.12 % en dietas hipoproteicas para gallinas ponedoras para mejorar la producción y calidad del huevo.
