Assessment of Vetom 1.1 probiotic effect on growth parameters and morphobiochemical blood parameters of calves

In modern conditions, growing of young cattle can not occur without application of various pharmacological agents designed to prevent diseases of early postnatal period, and to stimulate growth and development. Feed antibiotics are seen to be these means during the second half of the XX century almost all over the world. However, in recent years, due to undesirable side effects arising from their application in animal husbandry, many countries have reduced application of feed antibiotics or completely excluded them, replacing them by probiotics–live cultures symbiotic to normal microflora of the gastrointestinal tract bacteria. Vetom 1.1 is considered to be one of the most effective probiotics, which includes a recombinant strain of Bacillus subtilis (hay sticks) VKPM B-10641 (DSM 24613). It is characterized by revealed antagonism to pathogenic and conditionally pathogenic microflora of the intestine in a symbiotic relationship with the normal flora. The research was carried out in one of the farms of the middle mountain zone of the Republic of Altai and aimed at exploring the effect of probiotic Vetom 1.1 on some indicators of their growth and morphobiochemical composition of blood when feeding 6 months calves. The scientific and economic experiment conducted by means of the method of balanced groups, assumed that newborn Simmental calves received milk with 90 mg of Vetom 1.1 per 1 kg of body weight 2 times a day, from 1 to 14 days of life. The authors found out that 6 months calves from experimental groups significantly exceeded the ones from the control group in absolute and average daily weight gain on 11.8%; morphological and biochemical parameters of their blood showed a tendency to moderate increase within the physiological norm.
