| dc.description.abstract | In the experimental station, Fátima belonging to the ESPOCH, located in Puyo city at km 11, Tena road, in the Pastaza province; it was conducted an analysis to three levels of diatomaceous earth (diatomite), 150 g / day (T1), 175 g / day (T2) and 200 g /day (T3), in the control of gastrointestinal helminths and beef cattle, versus a control treatment (T0) by using both, male and female cattle during their growth-fattening stage, under a completely randomized design (CRD), with a bi-factorial, combinatorial, arrangement, whose experimental outcomes were subjected to: The analysis of variance (ANOVA), the Tukey´s test in order to separate the average values at 0.05 and 0.01 of probability, moreover; regression and conrrelation. Thus, it was determined that when using diatomeaceous 175 g / day (T2) the best final weights were yield (187.50 kg), as well as weight gain (30.20 kg), reduction in the parasite loas in Eimeria sp (72%), Haemonchus sp (100%) and Cryptosporidium sp (67.84%), according to the sex of the animals; best final weights were reached by male cattle (184.10 kg), in contrast to those reached by female cattle (178,15 kg), weight gain (30.90 kg) for male cattle, whereas; (26.10 kg) in female cattle. The reduction of parasite loads in both, males and females was similar with an effectiveness rate to Eimera sp (70.89%), Haemonchus sp (100%) and Cryptosporidium sp (92.17%). The greatest profit was achieved with diatomite 175 g / day whose indicator shows 1.20, which represents a profitability of 20%. Therefore, it is suggested to use diatomaceous 175 g / day as a feed suplement for cattle since it reduces parasite loads considerably as well as it improves the productive and economic parameters in livestock production. | |
