Abstract

PASQUETTI, T.J. et al. Crude glycerin for meat quails, from 1 to 14 and 15 to 35 days old. Arq. Bras. Med. Vet. Zootec. [online]. 2014, vol.66, n.5, pp.1547-1556. ISSN 0102-0935.  http://dx.doi.org/10.1590/1678-7225.

Three experiments were carried out aiming to determine the nutritive value and verify the performance of meat quails feed with crude glycerin (CG). In the first trial 75 quails were used, allocated in a completely randomized design, consisting in three treatments and five replications. The treatments consisted of one reference diet (RD) and two test diets (TD), in which the CG replaced the RD at levels of eight and 12%. The estimated value of metabolizable energy corrected for nitrogen balance was 4,893kcal/kg. In experiment two o, from d 1 to 14, 1,320 not sexed quails were used, allotted in a completely randomized design, with six treatments and 4 four replications. The treatments consisted of six diets with increased levels of CG (0; 3; 6; 9; 12 and 15%). The live weight (LW), weight gain (WG), feed intake (FI), feed conversion (FC), biomass accumulated body (BAB) and litter moisture (LM) increased linearly with the inclusion of CG. Considering the performance data, it can be concluded that CG can be included in the diets up to15%. In experiment three, d 15 to 35, 1,032 quails were used, allocated under the same conditions of experiment two. The WG, FI, BAB, LM, breast weight (BW) and breast yield (BY) increased linearly with the inclusion of CG. Considering the performance data, it can be concluded that the CG can be included in the diets up to the level of 15%.
