Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

According to the Kazakhstan national animal health monitoring system, the mortality rate of young farm animals ranges from 4.2% to 7.8%, with gastrointestinal diseases being the main registered condition. This study aimed to create a locally produced probiotic, formulated using a consortium of lactic acid bacteria, to enhance the immune function of young farm animals. The study utilized a newly developed probiotic designed to prevent and treat gastrointestinal diseases in young cattle. Modern molecular biological, zootechnical, biochemical, hematological, and immunological methods and techniques were used in the research. The potential advantages of the developed probiotic preparation Lactobact-ARZ are demonstrated, with optimization of its dosage in the diet to improve growth and development, increase live weight, and enhance immunity in young cattle. Calves that received probiotic-enriched milk demonstrated improved growth, development, feed utilization efficiency, survival rate, and hematological profile.
