“…No effects of supplemented treatments (P>0.05) could be observed in cecal Lactobacilli counts; however, total anaerobe counts tended to increase (P=0.07), Enterococci counts increased (P<0.05) and Escherichia coli counts decreased (P<0.05) due to probiotic supplementation (Table IV). These results are in partial agreement with those of Giannenas et al (2012) who did not observe differences in Lactobacilli, Enterococci and total anaerobe counts, but did observe lower Escherichia coli counts in the caecum of broilers fed a probiotic supplemented diet compared with the control. On the contrary, Mountzouris et al (2007) reported that including probiotics in the diet of broilers caused higher concentrations of Lactobacilli and gram-positive cocci (e.g., Enterococci, Pediococci) in the cecal microflora compared with the controls.…”

Probiotic effects on growth performance, carcass traits, blood parameters, cecal microbiota, and immune response of broilers were studied. Two hundred one-day-old male chickens were allocated to one of fi ve treatments (four replicates of 10 birds per treatment): control, and the same control diet supplemented with 0.005%, 0.01%, 0.015% and 0.02% probiotics. Probiotics in feed at 0.01% or higher levels of supplementation improved body weight gain (+12%) and feed conversion rate (-5%) compared with the control. There were no effects on carcass traits, but the relative weights of drumsticks and wings showed increasing and decreasing linear responses, respectively, to probiotic supplementation level. Blood plasma glucose and albumin contents linearly increased (from 167.1 to 200.5 mg dl -1 , and from 1.70 to 3.25 g dl -1 ) with increasing probiotic supplementation. Triglycerides and cholesterol contents were lower in probiotic supplemented treatments (average contents 71.3 and 125.3 mg dl -1 vs. 92.6 and 149.9 mg dl -1 in the control). Probiotics decreased cecal Escherichia coli counts, but had no effects on immunity related organs or immune response. The linear trends, either positive or negative, observed in many of the parameters studied, suggest that more studies are needed to establish the optimal concentration of probiotics in broiler feed.

“…Gut micro-flora have important effects on host animal health, nutrition and performance by affecting utilization of nutrients and development of the GI system of the host (Barrow, 1992). This interaction is complex and, depending on the activity and composition of the gut micro-flora, it can have either negative or positive effects on animal health (Giannenas et al, 2012). Probiotic products influence the intestinal microbial system of monogastric animals in multiple ways (Ng et al, 2009).…”

“…An example of animals exposed to such a stressor are high producing dairy cows; especially those in early lactation induced in a negative energy balance. Lee et al (2009), Giannenas et al (2012 and Salim et al (2013) demonstrated altered intestinal morphometric measurements when B. subtilis bacterial strains were fed to broilers, and showed an increase in villus height and crypt depth in the small intestine. This might occur in the rumen of mature cows, as well as in the post ruminal GI tract, leading to increased villus height and width thereby increasing surface area available for absorption leading to increased nutrient absorption.…”

Highlights A yeast culture (XPC) or yeast/microbial culture (YST) were added to a Control (C)  Milk yield was higher with YST, but not XPC, and NE output was higher vs C for both  There were no impacts of either YST or XPC on measures of rumen fermentation  Lower apparent digestion of OM and CP for YST vs C and mainly higher plasma AA  A post-ruminal YST effect improved gut health causing higher absorption efficiency AbstractOur aim was to determine effects of two S. cerevisiae yeast based direct fed microbial (DFM) feed additives on the productive response of high producing early lactation dairy cows. The study consisted of three high producing Holstein cow pens (± 315 cows/pen) in a 3 x 3 Latin square design experiment with 3 periods of 28 d each. The 3 treatments were: 1) Basal total mixed ration (Control), 2) Control supplemented with "XPC" yeast culture at 14 g/cow/d and, 3) Control supplemented with "Yeasture (YST)" DFM at 10 g/cow/d. Milk (P = 0.01), milk true protein (P = 0.01), lactose (P = 0.01) and energy (P = 0.02) outputs were higher for YST cows, and there was a tendency for milk fat (P = 0.07) to increase compared to Control cows. In contrast, milk and component yields were not impacted by feeding XPC.2 Total net energy (NE) output was higher for both DFM treatments versus Control (YST (P < 0.01) and XPC (P = 0.01)), but neither treatment impacted the NE level of the diets. Total tract apparent digestibility of organic matter (OM) and crude protein (CP) tended to be lower (P = 0.08 and 0.05) than Control for the XPC treatment, while total tract apparent digestibility of OM and CP for YST cows was lower (P = 0.02 and < 0.01 respectively) than Control. Total tract apparent digestibility of ash-free neutral detergent fibre (aNDFom) and starch were not affected by treatment, and there was no effect of either DFM treatment on microbial CP (MCP) flow from the rumen. Total plasma essential amino acid (EAA) concentrations tended to be higher (P = 0.07) with YST, which was mainly driven by increases in threonine (P = 0.03), tryptophan (P = 0.02), valine (P = 0.08) and histidine (P = 0.06). Although total plasma non-essential amino acids (NEAA) did not differ with YST feeding, there was an increase in concentrations of glycine (P = 0.04), asparagine (P = 0.03), tyrosine (P = 0.05), serine (P = 0.07), proline (P = 0.06) and taurine (P = 0.07). In contrast, XPC had no impact on plasma concentrations of any AA. Overall, MCP flow and whole tract aNDFom data suggest no substantive impact of either yeast additive on rumen fermentation, but whole tract digestibility of OM and plasma AA concentrations suggest a post-ruminal effect of YST wherein gut health improved thereby leading to increased efficiency of nutrient absorption.

“…In the present study, heat stress enhanced the intestinal colonization of enteric bacteria such as Clostridium and Coliforms at the expense of the beneficial bacteria such as Lactobacillus and Bifidobacterium. Similarly, recent reports indicated that supplementation with probiotics could increase numbers of Lactobacillus and Bifidobacterium and decrease numbers of Clostridium and Coliforms in broilers (Giannenas et al, 2012;Song et al, 2014). This indicated that heat stress can induce perturbation of the normal intestinal microflora which reduces innate protective mechanisms and increase the potential for pathogenic bacteria colonization.…”
