“…As the SCC values were very low in our study, suggesting mastitis in the herd was low, it was perhaps unlikely that there was an opportunity to decrease it further. Higginbotham et al (1999) reported no effect on BCS when a live yeast product was fed, which is in agreement with Soder and Holden (1999) and our results. In a literature review on effects of yeast products on the performance of lactating and growing animals, Robinson (2013) reported a slight increase in body weight gain with live yeast product feeding.…”

“…In contrast to our data, Stretenovic et al (2008) fed Yeasture and found lower milk SCC. This is consistent with Higginbotham et al (1999) who showed a tendency for SCC to decrease when live yeast was fed.

“…In contrast to our results, Kristensen et al (2014) reported no difference in milk production when a live yeast product was fed to dairy cows, but found that its addition decreased milk protein concentrations, which is also in agreement with a literature review by Robinson (2013) which showed that addition of live yeast decreases milk CP %. Erasmus et al (1992), Higginbotham et al (1999) and Soder and Holden (1999) found no effects on milk production or milk components when live yeast products were fed to dairy cows, but Higginbotham et al (1999) found that, due to a numerical increase in milk yield and some milk components, that there was an increase in milk fat, protein and solids nonfat yield when a live yeast product was fed. In contrast to our data, Stretenovic et al (2008) fed Yeasture and found lower milk SCC.…”

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.

Effects of the administration of Lactobacilli on body growth and on the metabolic profile in growing Maltese goat kids

-The aim of this study was to evaluate the effect of some lactobacilli on body growth and on the metabolic-nutritional status in growing goat kids. Twenty growing Maltese goat kids (10 Control and 10 Bios) were studied. The animals of the Bios group received a concentrate including 1 g·kg -1 of SEB Bovino ® (spray-dried), Akron S.r.l., Italy, with non bacterial components: gum arabic, soybean meal, silicate alum of magnesium, and with bacterial components: 10 11 cfu·kg -1 each of Lactobacillus acidophilus, Lactobacillus salivarius, Lactobacillus reuteri. Monthly, bio-metric and weight evaluations were carried out on each animal and individual blood samples were taken. The Bios group showed the highest body weight (Control 19 vs. Bios 23 kg P < 0.001), anamorphosis (Control 71 vs. Bios 78 P < 0.05) and body proportion (Control 35 vs. Bios 41 P < 0.001) indices; the lowest levels of Non Esterified Fatty Acids (Control 0.778 vs. Bios 0.403 mmol·L -1 P < 0.001), triglycerides (Control 0.21 vs. Bios 0.18 mmol·L -1 P < 0.05), urea (Control 8.83 vs. Bios 7.65 mmol·L -1 P < 0.05) and the highest levels of Alkaline Phosphatase (Control 270 vs. Bios 851 U·L -1 P < 0.01) and Creatine Kinase (Control 173 vs. Bios 285 U·L -1 P < 0.01). The results testify to the better metabolic activity of the Bios group which achieved, at the end of the trial (7 months old), about 99% of the morphological development of the adult, therefore an adequate structure for mating and going into production within the first year of life.goat kid / growing / Lactobacillus / morphological trait / metabolic profile

“…Some studies suggest probiotic supplementation might prove useful in averting environmental stresses; others claim they have no effects under stressful circumstances. However, the ability for A. oryzae to promote dairy cow health during periods of heat stress was not supported by several other studies (Higginbotham et al, 1993;Yu et al, 1997). Probiotics containing Aspergillus oryzae have also been shown to increase feed efficiency, milk production, and promote overall tolerance to heat stress (Gomez-Alarcon et al, 1990).…”
