Efecto del uso de diferentes niveles de microorganismos eficientes sobre los parámetros productivos de cerdos en pre levante.

Abstract

Worldwide, pig production is in constant and accelerated growth, this leads pig farms to strive to reduce production costs without neglecting the productive indices, since the profitability of the company depends on this. At present, alternatives are offered that allow improving the productive indices of animals such as growth promoters, including efficient microorganisms (EM). With the objective of evaluating the effect of the use of different levels of efficient microorganisms on the productive parameters of pigs in pre-raising, nine (9) pigs from the commercial crossing Hampshire * Duroc * Pietrain with an approximate weight of 9 kg ± 0.866 kg and 35 days of age, distributed in completely randomized blocks in three groups: control-CT treatment (without inclusion of EM); Treatment 1- T1 (inclusion of 1.5 mL of ME / kg of body weight); and 2-T2 treatment (inclusion of 3 mL ME / kg of body weight). During the 5 weeks of study the animals had constant control over feeding, after the study time it was determined that there were no significant differences between the treatments (p˃0.05) for the productive parameters evaluated (daily weight gain, index of feed conversion (ICA), feed efficiency index (IEA). Regarding the cost / benefit ratio, the results obtained show that the T2 treatment represented better economic advantages, since they presented the best weights at the end of the investigation period, because, on average, $ 5,662 was invested per kg of produced weight, with this it is concluded that the inclusion of efficient microorganisms in the diet of pigs in the prelifting phase does not have significant effects on the productive parameters evaluated.
