Effect of supplementation with mountain microorganisms as a probiotic in the feeding of Hubbard broiler chickens on productive parameters

Abstract

The research was developed in the period January - March 2020; This consisted in the addition of Mountain Microorganisms (MM) as a natural probiotic to the feeding of broilers of the Hubbard line in  different  percentages;  it  was  divided  into  4  stages.  Two  diets  were used in the study, the starter concentrate was offered from 1 to 20 days after hatching and the final fattening concentrate was offered from 21 to 42 days. Due to the nature of the experimental units,  a  completely  randomized  design  (DCA)  was  used  with  a  confidence level of 5%. The results of the processing of the data obtained  were  not  statistically  significant  for  all  the  variables.  Regarding live weight, in the sixth week of the study treatment T3 presented the best weights in the treatments under study (2134.60 g.) Followed by treatment T1 (2101.96 g.), T0 (2099.56 g.) and T2 (2055.53  g.).  Regarding  the  evaluation  of  the  food  consumption  variable, the treatment that had the highest consumption was T2 with (1284.00 g) followed by T3 (1283.96 g), T1 (1283.89 g) and T0  (1284.39  g);  Regarding  the  economic  variable  per  bird,  the  treatment  with  the  highest  economic  benefits  was  T3  with  an  amount of USD 4.15, surpassing T2 with USD 4.08, T1 with USD 4.05 and T3 with USD 3.94 respectively.Key words: Probiotics, feed consumption, feeding stages.
