“…They are commonly used as a growth promoting substance. Different results were reported in previous researches about the effects of probiotics supplemented in pre-weaning period on calf performance (Avila et al, 1995;Abu-Tarboush et al, 1996;Morril et al, 1995;Strzetelski et al, 1996;Feist et al, 1997;Kocyigit et al, 2015). Therefore in this study, effects of pre-weaning probiotic treatments on growth performance of calves were investigated.…”

The present study was conducted to assess the effects of pre-weaning probiotic treatments on growth performance of male Holstein calves. For experimental treatments, 20 male calves were divided into 2 groups as of control and treatment group. Control group calves were supplied with fresh milk daily in two meals without any growth promoting supplement. Together with fresh milk supply, treatment group calves were supplied with additional 2 g probiotics to their morning meal. Throughout 56-day milk-feeding period, live weights (LW) and feed consumptions (FC) of the calves were determined. As compared to the control group, probiotic-supplemented calves had 5.25% higher weaning live weight and 11.4% higher daily live weight gain (P less than 0.05). Probiotic-supplemented calves consumed 2% more feed than the control calves (P>0.05) and had 9.52% better feed conversion ratio than the control group calves (P less than 0.05). Probiotic supplementation did not affect blood biochemical parameters significantly (P less than 0.05), except ALT, triglyceride and iron levels (P less than 0.05). It was concluded that probiotic supplementation during milk-feeding period improved growth performance of experimental Holstein calves.

The influence of "Stimix Zoostim" and "Normosil" probiotics on fecal microflora, hematologic indicators, nutrient digestibility, and growth of mother-bonded calves

Aim: This paper presents the results of the studies on "Stimix Zoostim" and "Normosil" probiotics and their influence on fecal microflora, hematologic indicators, immunoresistance, nutrient digestibility, and growth intensity of mother-bonded calves. Materials and Methods: The calves of the control group were fed with their basic diet (BD) without "Stimix Zoostim" or "Normosil", whereas the calves of the experimental group were fed with their BD supplemented with "Stimix Zoostim" and "Normosil". For 10-20-day-old calves, the daily dose was 10 mL per head, whereas 21-90-day-old calves received 15 mL of probiotics per head per day. The calves of the experimental group were administered probiotics every day. Calves aged 10 to 60 days received probiotics with milk, and then at the age of 61 to 90 days, received probiotics with water. (This is a sequential process. At 60 days old, calf rearing with milk stops, and after that, we use probiotics added to water to rear them). Both groups were administered probiotics twice a day, specifically 50% of the daily dose at each feeding time. Results: The results in this study proved that "Stimix Zoostim" and "Normosil" probiotics exhibit high probiotic activity and have a positive effect on the calves' fecal microflora. Feeding the calves with probiotics resulted in a significant increase in the number of normal flora, such as lactic acid bacteria and bifidobacteria, and a decrease in the amount of Escherichia. It also resulted in an increase in red blood cells, hemoglobin, and ?-globulins within the physiological range. In our study, we found that the phagocytic reaction in the blood serum of the experimental group was slightly enhanced, suggesting a high response of the body to infectious agents. Conclusion: Thus, the group of calves receiving probiotic "Stimix Zoostim" exhibited an exceedance of phagocytic activity by 4.8% and the group receiving "Normosil" by 4.4%, in comparison with the control group. The daily dose of 10 mL of probiotics per head for 10-20-day-old calves and 15 mL per head for 21-90-day-old calves also had a positive effect on nutrient digestibility, growth, and forage consumption. The economic benefit per animal was 149.23 and 157.0 rubles, respectively.

“…This has prompted several studies on developing and promoting alternative additives such as probiotics, prebiotics, plant secondary metabolites, acidifiers, enzymes, bacteriocins and bacteriophages [61,62]. Combined probiotics and exogenous enzymes, when used as feed additives, have demonstrated beneficial impacts on growth performance and on the weight-gains-to-feed ratio in calves [63,64].…”

Probiotics in Animal Husbandry: Applicability and Associated Risk Factors

Probiotics have been emerging as a safe and viable alternative to antibiotics for increasing performance in livestock. Literature was collated via retrieved information from online databases, viz, PubMed, MEDLINE, ScienceDirect, Scopus, Web of Science and Google Scholar. Besides improved immunomodulation and nutrient digestibility, in-feed probiotics have shown drastic reductions in gastrointestinal tract-invading pathogens. However, every novel probiotic strain cannot be assumed to share historical safety with conventional strains. Any strain not belonging to the wild-type distributions of relevant antimicrobials, or found to be harbouring virulence determinants, should not be developed further. Modes of identification and the transmigration potential of the strains across the gastrointestinal barrier must be scrutinized. Other potential risk factors include the possibility of promoting deleterious metabolic effects, excessive immune stimulation and genetic stability of the strains over time. Adverse effects of probiotics could be strain specific, depending on the prevailing immunological and physiological condition of the host. The most crucial concern is the stability of the strain. Probiotics stand a good chance of replacing antibiotics in animal husbandry. The possibility of the probiotics used in animal feed cross-contaminating the human food chain cannot be downplayed. Thus, the established safety measures in probiotic development must be adhered to for a successful global campaign on food safety and security.
