Lallemand and Nuevotec Share Probiotic Information at Bangkok seminar                         

Last month, Lallemand and Nuevotec, the feed additive and ingredients provider who distributes Lallemand Animal Nutrition products in Thailand, organised a seminar about the successful use of probiotics in livestock feed, chaired by animal nutrition expert, Associate Professor Dr. Jowaman Khajarern from Khon Kaen University.

 

Around forty professionals from the country’s top feed firms and animal producers gathered to discuss the potentials of probiotics to control zootechnical performances, health, and safety in various animal productions, from swine to aquatic species, poultry and bovines.

 

Markets overview and regulatory issues were covered by B. Rochet, Marketing and Development Manager for Lallemand Animal Nutrition, in charge of Asia, and Chairman of the European Probiotic Association; followed by practical case studies, with a particular focus on swine and poultry applications, by Yannig Le Treut, Veterinary Doctor and in charge of Lallemand’s worldwide monogastric activities.

 

B. Rochet concluded the seminar: “The continuous use of antibiotic in animal feed comes to its limits in Asia too, due to increasing pressure from the outside and the inside. Both exportation and increasing consumer awareness and demand for safe food are shaping tomorrow’s feed additive market in Asia.”

 

This event confirms Lallemand presence in Asia, a booming market for animal productions.

 

 

A flourishing market

In today’s global market, driven by consumers demand and international regulations, the animal producer must quickly evolve towards safe, natural and environment-friendly animal production methods in line with international regulations (e.g. The European ban on antibiotics growth promoters conditions export for non-member states), while ensuring optimal productivity.

 

In this context, probiotics, with their track-record of scientific and practical evidences, represent a safe, natural, and perfectly profitable solution to improve zootechnical performances, while controlling animal health, safety and well-being as well as feed and food safety.

 

The probiotic concept has been recognised by Northern European countries for a long time now, and European and Japanese markets are experiencing strong growth. For the rest of Asia, the market is still very young, but holds huge potentials, especially in India and China. This is even more true since January 2006 and the ban of all antibiotic growth promoters in Europe.

 

Probiotics are one of the very few natural alternatives that are fully approved for use in feed by the European authorities, and this is the strictest regulation in the world, that not only guarantees the origin and safety of the feed additive, but also its efficacy, numerous field data and scientific back-up being necessary to file a dossier.

 

Specific probiotic solutions and applications

Answering the challenges of today’s pig production

Two complementary probiotics from Lallemand are fully approved by the EU authorities to help control performances and sanitary conditions during the whole pig production cycle. Results and practical applications were discussed during the seminar

 

 

A-Enhancing the farrowing process to improve performances

Live yeast S. cerevisiae boulardii I-1079 (Levucell®SB) has been developed for monogastric species. Its action in the gut has been described as a shield effect that reinforces the gut microflora and protects the animal’s digestive tract.

 

It is registered in Europe as a natural feed additive for piglets and sows. Its addition to sows feed during late gestation and lactation significantly increases feed intake and feed efficiency, decreases weight loss in lactation and improves litter weight and survival. Used in piglets, Levucell SB decreases mortality, increases weight gain and prevents c. difficile-associated diarrhoeas.

 

Yannig Le Treut comments : “ In the last decade, pig production has had to face new challenges: sows hyperprolificacy and increased litter heterogeneity result in important losses. In fact, up to 50% of the piglets gained from the genetic progress are lost before reaching the slaughterhouse.

 

The proven benefits of Levucell SB for sows and their litter can considerably help pig producers facing the issues linked to hyperprolificacy: piglets are more vigorous and heavier at birth, litter homogeneity is improved, and piglets growth and survival increase.”

 

B-Improving growth and hygiene in fattening pigs

Lactic acid bacteria P. acidilactici 18/5M (Bactocell®) is recognised for its ability to strengthen the gut microflora of monogastric species, with a positive impact on pathogens control and feed digestibility. In fattening pigs, Bactocell increases feed conversion rates and weight gain and improves health and safety.

 

Bactocell is available for both solid and liquid feed applications in piglets and fattening pigs. In the seminar, particular interest was drawn on liquid feed and fermented liquid feed applications, recognized for their benefits on performances and safety. In fact, the lactic bacteria in Bactocell has the ability to produce rapidly and exclusively large quantities of lactic acid, which inhibits pathogens growth (salmonella).

 

By forming a positive biofilm at the surface of the machine and pipes, Bactocell prevents contamination of the feed and the feed machine and pipes.

 

Poultry production: a success story

 

Poultry production is a mature, yet evolving market, with high pressure on costs and tough competition on one side, and increasing consumer awareness and safety regulations on the other. Only solutions with proven return on investment are acceptable. During the seminar, Yannig Le Treut showed how probiotic can fit in the picture by improving feed conversion rate (FCR) and offering increased meat and egg yield. For example, in broilers, ADWG is improved by nearly 4%, FCR by 3-5%.

 

Probiotics are good ally in pathogens control in poultry, an environment very prone to contaminations.

 

The lactic bacteria in Bactocell can protect the gut from pathogens. This is due to three main actions in the gut:

1.      Strengthening of the gut flora (Lactic acid production, pH decrease at microenvironmental levels, and total lactic acid flora increase)

  1. Enhancement of gut health (improved gut maturity and feed digestibility)
  2. Decrease of undesirable gut flora.

Experimental pathogen challenges with S. enteritidis showed that Bactocell actually prevented Salmonella colonization of hens gut, as well as eggs contamination. Similarly, Bactocell has been shown effective to limit E. coli, C. perfringens and S. typhimurium gut infection in broilers.

 

Levucell SB is subject of a patent in the US covering the protection against salmonellas.

 

 

Ruminants: specific live yeast

The use of live yeast in ruminants is not new, the first scientific publications go back to the 1920s, and before that, the Japanese were already using beer to give its unique quality to Kobe beef.

 

Today, ruminant specific yeast strains have been developed and light has been shed on their modes of actions in the rumen. Ruminant specific live yeast strain Saccharomyces cerevisiae I-1077 (Levucell®SC) has been specially selected and developed for its activities in the rumen. It has the ability to improve rumen microflora and function, enhancing digestion and nutrients intake. Levucell SC significantly increases feed efficiency, which is reflected in improved milk and muscle production, giving good return on investment to the producer. Most importantly, rumen health is improved, with a positive impact on cows overall health and well-being: sub-acidosis, bloating and acidosis-related troubles are reduced, which is of particular importance at times of stress, such as heat stress, transportation, feed transition...

 

The effects and modes of action of Levucell SC are widely documented by over 40 scientific publications and tens of field trials around the world. Recently, Dr. Alex Bach (IRTA, Spain) showed that Levucell SC improves rumen pH and dairy cow feeding pattern (feed intake and meal frequency are increased) in conditions close to commercial dairy farms.

 

In fattening beef, the use of live yeast Levucell SC proves to be a good alternative to growth promoting ionophore monensin. Although via different pathways, both bring similar health and performances benefits to the animal and the producer.

 

New developments in aquaculture

In aquaculture, the use of live micro-organisms to help control environmental microflora in tank or ponds and keep pathogens at bay is known (bioremediation), while the probiotic concept (live microorganisms in the feed) is fairly new and shows very promising results in various aquatic species.

 

In Asia, where shrimp production is a primary market, Lallemand has already conducted several trials showing the benefits of Bactocell on shrimp growth rate, survival rate, and microbiological status. A new research trial has shown that the growth of Litopenaeus stylirostris shrimps was increased by about 30% in ponds, while resistance to vibrio infections was increased by more than 75%, and shrimps gut microbiological studies supported these findings. This project is still on-going, and investigators are now looking deeper into the modes of action of the probiotic in the animal gut (M. Castex, IFREMER/Lallemand research project).

 

Positive results have also been obtained with probiotics in other aquatic species:

- Trials conducted in Viet Nam in 2003 showed that Bactocell improves viability and weight gain of Red Tilapia Juveniles. Growth rate increased by 30% while relative mortality decreased by 20.8% after 3 weeks supplementation.

 

- A trial on Japanese Eel (China, 2004) demonstrated that Bactocell had a significant effect on growth (final mean weight per fish + 29%). Feed conversion rate, survival and immune parameters were also improved.

 

This is a brief overview of probiotic applications in various animal production, each of which is  supported by trials, scientific background and user observations.

 

In all these examples, probiotics appear as a profitable, safe and recognised solution.

 

In parctice, we must keep in mind that their use should always be part of a more global approach which should take into account the animal and its environment, and cover other parameters, such as formulation, feeding programs, animals management, hygiene.
