The efficiency of application of biological preparations based on the Bacillus strain in the technology of growing dairy calves

In industrial farms, it is not easy to optimize the content of nutrients and ensure a balanced diet for feeding animals. Up to the present moment, one of the common methods of resistance with diarrhea and the weakening of immunity in young cattle remains the use of antibiotics. Such additives are used not only to treat bacterial diseases, but as growth stimulants. The systematic usage of antibiotics in veterinary medicine and in feeding leads to the fact that many pathogenic and conditionally pathogenic bacteria become resistant to them, and bacterial diseases do not respond to the treatment. One of the main and effective ways out of the current situation may be the widespread use of probiotics in dairy cattle. The research reflects the comparative characteristics of the main physiological parameters of calves after the application of two preparations "Olin" and "Triolin" based on the spore-forming strain Bacillus. Studies have shown that the use of both drugs has a positive effect on the growth of young animals and the microflora of the rumen. The average live weight of the calves at the end of the experiment exceeded the control group by 1210 g (2%, P function show_eabstract() { $('#eabstract1').hide(); $('#eabstract2').show(); $('#eabstract_expand').hide(); }
