Evaluation of different calcium grain sizes in laying hens diet
The calcium grain size is important for absorption efficiency and calcification of the egg, especially when the bird’s feeding decreases. In recent years, several studies have evaluated the effect of different calcium grain sizes on the feeding of laying hens; however, the results are controversial....

| description | The calcium grain size is important for absorption efficiency and calcification of the egg, especially when the bird’s feeding decreases. In recent years, several studies have evaluated the effect of different calcium grain sizes on the feeding of laying hens; however, the results are controversial. This research evaluates the effect of particle size on the posture rate, feed intake, egg weight, and feed conversion. 120 Hy-line White 90 weeks old laying hens, randomly distributed, received 4 treatments, each one with different calcium particle size: T1 =less than 1 mm, T2=3 mm, T3=6 mm, and T4=9 mm. Each treatment was repeated 10 times with 3 birds per experimental unit. The posture percentage showed a quadratic effect, with the percentage increasing as the particle size increased until T3; however, T4 was the treatment with the lowest posture percentage and feed intake. Although there were no significant differences between treatments for egg weight, feed conversion had the lowest value with T4. In conclusion, particle sizes of 3 mm and 6 mm have no adverse effects on animal performance parameters in 90 weeks old laying hens. |

In recent years, several studies have evaluated the effect of different calcium grain sizes on the feeding of laying hens; however, the results are controversial. This research evaluates the effect of particle size on the posture rate, feed intake, egg weight, and feed conversion. 120 Hy-line White 90 weeks old laying hens, randomly distributed, received 4 treatments, each one with different calcium particle size: T1 =less than 1 mm, T2=3 mm, T3=6 mm, and T4=9 mm. Each treatment was repeated 10 times with 3 birds per experimental unit. The posture percentage showed a quadratic effect, with the percentage increasing as the particle size increased until T3; however, T4 was the treatment with the lowest posture percentage and feed intake. Although there were no significant differences between treatments for egg weight, feed conversion had the lowest value with T4. In conclusion, particle sizes of 3 mm and 6 mm have no adverse effects on animal performance parameters in 90 weeks old laying hens. En los últimos años, diversos estudios se han realizado para evaluar el efecto de la granulometría del calcio en la alimentación de gallinas ponedoras, dada su importancia en la eficiencia de la absorción de este mineral para la calcificación del huevo, especialmente en épocas en las que el ave disminuye el consumo de alimento; sin embargo, los resultados obtenidos son controvertidos. En el presente trabajo se propuso evaluar el efecto del tamaño de la partícula de calcio sobre el porcentaje de postura, el consumo de alimento, el peso del huevo y la conversión alimenticia. Se sometieron 120 gallinas ponedoras de la línea Hy-line blanca de 90 semanas de edad, distribuidas al azar, y se aplicaron 4 tratamientos, cada uno con partículas de calcio de diferente tamaño: T1=menor a 1 mm, T2=3 mm, T3=6 mm y T4= 9 mm; cada tratamiento tuvo 10 repeticiones de 3 aves en cada unidad experimental. Hubo un efecto cuadrático para el porcentaje de postura entre los tratamientos a medida que aumentó el tamaño de partícula hasta el tratamiento T3, siendo el tratamiento T4 el que presentó menor porcentaje de postura y menor consumo de ración. Aunque no hubo diferencias significativas entre los tratamientos para el peso del huevo, la conversión alimenticia fue mejor en el tratamiento T4. Se concluye que es posible utilizar los tamaños de partícula de 3 mm y 6 mm sin afectar negativamente los parámetros de desempeño animal en gallinas ponedoras de más de 90 semanas de edad.
