This article is devoted to assessing the effect of probiotic preparations on the change in the weight of broiler chickens in different periods of growth and development. As influencing factors, three different preparations were selected, which were given to the chickens of the respective experimental groups. The obtained average values of different groups differ markedly from each other. The dynamics of changes in the averages is shown in the graphs. In view of the normal distribution of all available data, Student's t-test was used as an evaluation criterion. It was revealed that the use of probiotics has a significant positive effect on the weight of the bird. [ABSTRACT FROM AUTHOR] |
