Dose effect of Actisaf Sc 47 yeast probiotic () supplementation on production, reproduction, and negative energy balance in early lactation dairy cows.

The study evaluated the dose effect of dietary supplementation with yeast probiotic (CNCM I-4407, 10 CFU/g, Actisaf Sc 47; Phileo by Lesaffre, France) on production, energy metabolism, and reproduction in lactating dairy cows. About 117 multiparous Holstein cows from 3 to 60 d in milk held in a barn with an automatic milking system were enrolled in a randomized complete block design and blocked according to calving day, parity, and previous milk yield. The cows were assigned to a basal diet (15% CP, 22% starch) plus either 5 g (Y5 group,  = 39), 10 g (Y10 group,  = 39), or 0 g (CON,  = 39) of yeast probiotic, presented on top of concentrate fed in the robot.

Does micro-granulated yeast probiotic () supplementation in milk replacer affect health, growth, feed efficiency and economic gain of calves?

The goal of calf feeding systems is to provide calves with optimum nutrition to promote growth, health, and future milk production and to reduce antibiotic use which leads to a need for alternatives that reduce illness and promote growth in dairy calves. We hypothesized that feeding live yeast would improve gastrointestinal health and growth performance of calves. The aim of this study was then to evaluate the effects of supplementing a yeast probiotic (CNCM I-4407, 10 CFU/g, Actisaf® Sc47 powder; Phileo by Lesaffre, France) in milk replacers (MR), on health and growth of pre-weaned calves.

Dietary Supplementation of a Live Yeast Product on Dairy Sheep Milk Performance, Oxidative and Immune Status in Peripartum Period.

This study evaluated the dietary administration of live yeast on milk performance and composition, oxidative status of both blood plasma and milk, and gene expression related to the immune system of lactating ewes during the peripartum period. Chios ewes were fed either a basal diet (BD) (Control, = 51) or the BD supplemented with 2 g of a live yeast product/animal (ActiSaf, = 53) from 6 weeks prepartum to 6 weeks postpartum. Fatty acid profile, oxidative, and immune status were assessed in eight ewes per treatment at 3 and 6 weeks postpartum.

Particulates and bacteria removal by ceramic microfiltration, UV photolysis, and their combination.

Membrane microfiltration (MF) or ultrafiltration (UF) systems of activated sludge is crucial part of a bioreactor process used in municipal wastewater treatment. In this study, both cylindrical and flat sheet ceramic membranes were used to treat municipal wastewaters. The effects of removing water turbidity and coliform bacteria from an artificial wastewater were studied by performing batch experiments by MF and ultraviolet (UV) photolysis of 254 nm wavelength.
