    Rabbit production has been one of the activities that consists of the breeding, reproduction and fattening of domestic rabbits in order to offer meat with a high biological and protein value. The objective of the research was to evaluate the effect of the inclusion of different levels of efficient microorganisms in the feed in rabbits of the New Zealand breed in the growth and finishing stages. For the investigation, a completely randomized experiment design with a factorial arrangement with a total of 5 replicates for each sex (females and males) was used. The animals were divided into three treatments (0, 2.5 and 5% efficient microorganisms). The productive parameters weight, weight gain, feed intake, feed conversion, carcass yield and cost-benefit ratio were evaluated. In general, the inclusion of efficient microorganisms in rabbit feeding showed significant effects (p>0.05) on production yields, with treatment T2 being superior to the other treatments. The effect of microorganisms according to sex showed a higher performance in the T2 treatment for male rabbits with a weight of 2357.75 g, weight gain of 20.21 g/day and feed conversion of 21.52. In the same way, the inclusion of efficient microorganisms in 5% in the feeding of female rabbits presented a better performance in weight with a total of 2392.50 g, weight gain of 20.29 g/day and feed conversion of 3 .96. The economic profitability was better in the T2 treatment with a total of $1.16 (males) and $1.15 (females). It is concluded that the use of efficient microorganisms in the feeding of rabbits obtained a better performance in the productive parameters and economic performance. Keywords: feeding, rabbits, efficient microorganisms, productive performance.

    ACTIVIDAD FITOTÓXICA Y TAMIZAJE FITOQUÍMICO DE LOS EXTRACTOS DE HOJAS DE BALSA ( Ochroma Pyramidale ) PARA LA PRODUCCIÓN DE BIOHERBICIDAS.

    The use of waste of plant origin as raw materials plays a fundamental role in the economic and social well-being of Ecuador. The research was developed with the objective of determining the presence of secondary metabolites and their potential phytotoxic activity from balsa leaves (Ochoroma pyrdamile) for the production of bioherbicides. Extracts were obtained by means of maceration and placed in a rotary evaporator at a temperature of 45 °C with an atmospheric pressure of 175 mbars for the respective phytochemical screening and analysis of the phenolic content. The allelopathic effect of balsa extracts on lettuce seeds (Lactuca sativa) was evaluated. The aqueous and ethanolic fractions of teak leaves were used as part of the treatments to contrast the allelopathic effects of the bolla leaf extracts. A completely randomized design was used with the inclusion of 3 concentrations of the extracts in their two aqueous and ethanolic fractions (500, 1500 and 2500 mg-L-1), in each treatment the variables number of germinated seeds, percentage of germination, allelopathic response index, length of the radicle, hypocotyl and cotyledons. A flowchart and diagram for pilot plant production were developed according to each of the processes applied to obtain the extracts. The results show a high presence (+++) of saponins, tannins, reducing sugars in the aqueous and ethanolic phases in the extracts of balsa leaves. The greatest allelopathic effect occurred at concentrations of 2500 mg/l of the ethanolic fractions of both plant species, being less than 44%. The material balance of the extracts from the leaves of both shrub species show a yield of 6.08% (teak) and 5.94% (raft). The fractions of the ethanolic extracts of the balsa leaves showed an allelopathic effect on the lettuce seeds.Keywords: Balsa, bioherbicide, allelopathic effect, metabolites, screening, teak.

    Rabbit production in Ecuador, in recent years, has witnessed a gradual development associated with the commercial and nutritional interest of meat. The research was developed with the objective of evaluating the feeding potential of Cerdaza in the feeding of rabbits in the Chone canton of the province of Manabí, Ecuador, during the growth and fattening stages. The sow meal was obtained from the pig production area of the Faculty of Zootechnical Sciences. A Completely Random Design (DCA) was used, for the interpretation of the results the analysis of variance (ANADEVA) will be carried out, with three treatments (5, 10 and 15%) and a control. The productive parameters initial weight, weight, weight gain, feed intake, feed conversion, carcass yield and cost-benefit ratio were evaluated. The results of the analysis of variance showed significant effects (p<0.05) when including 15% of sow meal in the finishing stage, reaching a weight of 2389 g, weight gain of 20.97 g/day, feed conversion of 3.94 g/g. However, during the growth stage, the results did not show statistical differences between the average values of the parameters weight, feed intake and feed conversion, while weight gain was significant (p<0.05) with the other parameters. Carcass yield (%) was not significant (p>0.05) with values ranging from 59.82 to 60.17%. The economic performance was better in the T3 treatment, reaching averages of $1.19 (for every dollar invested, nineteen cents of profit). It is concluded that the inclusion of bristle meal showed a better performance in the productive behavior of rabbits of the New Zealand breed.
