Multi-Functional Yeast Culture for Livestock and Aquaculture Production (Part 2)
DIAMOND V XP CULTURE IS DIFFERENT
Diamond V XP Yeast Culture is different from other yeast products in the feed market. It is a fermented product and not just yeast cells or yeast biomass. Manufactured by Diamond V Mills, Inc., this unique yeast culture product is more like a fermented beer, wine or bread than like baker’s yeast or an active dry yeast blend. Its vital components include yeast cell walls (beta-glucans and mannan-oligosaccharides or MOS ). yeast cell solubles and metabolites (organic acids, peptides, vitamins, lipids, oligosaccharides, nucleotides, amino acids, esters, and alcohols).
The guaranteed analysis of Diamond V XP Yeast Culture is as follows: not less than 12 percent crude protein; not less than 3 percent crude fat; not more than 6.5 percent crude fiber.
PRODUCTION OF FERMENTATION METABOLITES
Production of nutrilites or fermentative metabolites by the yeast cells is the principle behind the yeast culture fermentation. A specific culture media is inoculated with live yeast cells, allowed to ferment under a specific set of conditions, and then the entire fermented media is dried. It contains both the residual live yeast cells used in the fermentation as well as metabolites or metabolic byproducts which the yeast produced.
Yeast culture, a very complex product, contains both the “intracellular” yeast cell nutrients and the “extracellular” metabolites of fermentation. Simply feeding yeast cells will not duplicate the total nutrient range found in yeast culture.
YEAST CULTURE AND THE GUT
The intestine or “gut,” is one of the most important immune organs in the animal body (other immune organs include the thymus, spleen, and bone marrow). The tubular organ is a site of constant immune response against bacteria, viruses, toxins and others. The body has a number of defensive systems to protect itself from disease-causing microbes or pathogens in the intestine. The constant battle occurs in every animal.
This is so because of the presence of beneficial or good bacteria, which are involved in establishing a normal and healthy status of the digestive system.
THE ROLE OF MICROBIAL METABOLITES IN IMMUNITY
The growth, of beneficial bacteria like Lactobacilli and Bifidobacteria, is enhanced by MOS and fermentation metabolites. Likewise, the proliferation of bad bacteria is impaired due to the presence of MOS in yeast and competitive exclusion. The activation of intestinal immunity also reduces the effects of pathogenic bacteria.
Mode of Action
In the upper tract, Diamond V XP Yeast Culture nurtures lactic bacteria like Lactobacilli, producing an indirect “probiotic” effect, which maintains optimal nutrient absorption in the small intestine. It stimulates the beneficial bacteria in the hind gut, resulting in enhanced fermentation and digestibility. It also improves feed-palatability, feed intake, and animal production efficiency.
BENEFITS OF DIAMOND V XP
With Diamond V XP Yeast Culture, you can expect improved immune response, minimized stress on animals, increased palatability of feeds, reduced effects of mycotoxins, increase in beneficial bacteria and impair the proliferation of bad bacteria in the gut, improved intestinal integrity, and better feed efficiency.
Swine: Increased milk production in lactating sows; increase in litter size; higher weaning weights; lower pre-weaning/post-weaning mortality; and higher-feed intake.
Poultry: Broilers – Lower mortality; reduced fecal ammonia; better uniformity of flock; and improved feed efficiency. Layers – Lower mortality; better uniformity of egg size; and higher egg production.
USE IN AQUACULTURE
An increasing body of research indicates that yeast cultures may have important benefits in aquaculture feeds as sources of nucleotides and beta-glucans, and as potential growth promoters.
Nucleotides, the basic building blocks of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), are required for all metabolic process and are naturally occurring in all foods of animals and vegetable origin. Animals utilize nucleotides present in food; most cells have the ability to synthesize them. Their use in aquaculture is a relatively recent innovation. Although few observations exist regarding the use of these products for fish and shrimp, there will be more as a number of products are being commercially used with good results. A review of the literature suggests that nucleotides derived from yeast affect growth and disease resistance in farmed fish (tilapia) and, based on lab observations, in shrimp.
Beta-glucans, the subject of much research in aquaculture, have been shown to have a beneficial impact on disease and stress resistance under certain culture conditions. Research has focused on demonstrating that the use of various glucans results in protective immunity in fish. Many studies have focused on direct measurement of various immune parameters. Similarly in shrimp, research has focused on immunostimulatory effects of beta-glucans as shrimp cannot be vaccinated against disease, and negative implications of antibiotic use have grown.
Glucans have been found to act on the immune system of various animals including fish and shrimp by inducing a potent short-term non-specific immune response. This has resulted in protection against various pathogens. When used in conjunction with immunization or other treatments, they have been found to result in potentiation and increased the efficacy of immunization and other treatments such as antibiotic treatments.
