HURTADO-NERY, Víctor L.; GUEVARA-PAEZ, Jonny Fabiola  and  FORERO-OSUNA, Dumar J.. Calcium levels in layers quail. Orinoquia [online]. 2017, vol.21, n.2, pp.46-50. ISSN 0121-3709.  https://doi.org/10.22579/20112629.417.

In order to evaluate the effect of calcium levels in the diet on performance of quails it was performed this work in quail Unit of the University of the Llanos, with 240 quails 75 days old and 151.9 ± 8.5 g weight for 26 weeks, distributed in a completely randomized experimental design, with four treatments, six replications and 10 birds per repetition, for a total of 24 experimental units. The birds were housed in wire cages, five-storey modules with three divisions per floor, equipped with linear feeders and automatic drinkers. Treatments were made by inclusions of limestone (4.9; 5.28; 5.67 and 6.06) for diets 2.30; 2.45; 2.60 and 2.75% calcium. Calcium levels influenced egg production (80.19, 81.76, 71.67 and 79.15%), daily feed intake (24.26; 24.76; 24.50 and 24.53 g / bird / day), feed conversion per dozen eggs (0.333, 0.340, 0.389 and 0.347) and mass conversion Egg (2.77, 2.84, 3.24 and 2.89) on egg weight (10.91; 10.69; 10.55 and 10.74 g) there was no effect (P> 0 05). In conclusion, the level of calcium that leads to better production parameters is 2.48%.
