“…In the search for natural alternatives for the management of broiler chickens to replace antibiotics and chemical present in the feed that is offered to the animals, it's emphasized the use of enzymes (Méndez et al, 2012;León et al, 2014), prebiotics (Velasco et al, 2011;González et al, 2014), probiotics (Rondón et al, 2008;Blajman et al, 2015), organic acids (Gonzáles et al, 2013;Ortiz et al, 2012), natural coccidiostats (Tsinas et al, 2011;Major et al, 2011) natural pigments (Rojas et al, 2015;Chacón-Villalobos et al, 2016), medicinal plants (González and Jiménez, 2011;Rodrigues et al, 2011;Lambrecht et al, 2013;Silva et al, 2014;Chiriboga et al, 2015;Sánchez et al, 2016), among others, have demonstrated efficacy and on its application allow to obtain harmless products for the human being.…”

The objective of this study was to evaluate the effects of the addition of zeolite on the feeding of Cobb 500 chickens in the productive parameters. The work was carried out in an integral farm of Ecuador, adopting the standards of biosafety and animal welfare for the breeding of poultry; no vaccines or drugs were administered. 200 chickens (1-day old) were studied for 42 days and distributed in 5 treatments, each one with 4 replicates (10 chickens per replicate, randomly selected); the treatments were: T1(control), T2(zeolite 2%), T3(zeolite 3%), T4(zeolite 4%) and T5(zeolite 5%). All of the groups were fed with BALMAR, a commercial feed (Pre-initial: 22.56% CP, 3150 Kcal/kg ME; initial: 21% CP, 3200 Kcal/kg ME; grow-out: 19.5% CP, 3250 Kcal/Kg ME), T1 included a commercial toxin trapper, for all other groups zeolite was added as a substitute for the commercial toxin trap. The variables studied were: feed and water consumption, feed conversion ratio, live weight and mortality. The data were processed with the statistical program Stat graphics Centurion XV.I, by means of ANOVA analysis. The results of this experiment showed that there were no significant statistical differences in water consumption, food intake and feed conversion when comparing the treatments with the control, although, the final weight showed statistical difference (p<0.05). The highest mortality was recorded in T1 (12.5%). It is concluded that at higher zeolite increase, better effects, thus the live weight of T5 (1638.9±46.7) was statistically similar to the control (1734.3±49.3); water and feed consumption and feed conversion rate were not affected; possibly the reduction in mortality was due to the toxins trapping action of zeolite.

The present research aimed to evaluate the shrimp waste meal (SWM) in the diet of European quails in the production phase. Firstly, a metabolism trial was carried out with 96 quails of 28 days of age distributed in an completely randomized design (CRD) with three treatments (reference diet and two test diets in which SWM replaced 20% and 40% of the reference diet) and four replications of eight birds. It was observed that the nutritional composition of SWM is within the variation found in the literature, differing only in the sodium content. There was no difference in apparent metabolizable energy (AME) and apparent corrected for nitrogen balance (AMEn) values. In the performance trial 200 quails of 28 weeks of age were distributed in a CRD with four treatments (0, 5, 10 and 15.0% of inclusion of SWM) and five replications of ten birds. There was reduction in the nitrogen metabolization coefficient (NMC) with the inclusion of 15% SWM. The feed intake, production and egg mass worsened with 15% inclusion, causing a linear reduction of these variables. The inclusion of SWM at all levels reduced the values of specific gravity and Hugh units, and the level 15% promoted reduction in shell percentage and shell thickness. No difference was observed on any of the economic variables. It was concluded that the AMEn of SWM is 2,377 kcal/kg DM and that the inclusion of SWM in the diet of quails in production can be up to 10%.
