ALPHA-MONOLAURIN STIMULATES THE IMMUNE SYSTEM

Bacterial challenges with gram-positive bacteria in monogastric animals have a large impact on several aspects of animal husbandry, including higher medication costs, development of antibiotic resistance and reduced growth rates and feed efficiency. Among the many gram-positive bacteria that have a devastating effect on animal health and production, the following are the most common:

  1. Staphylococcus spp (facultative anaerobic cocci)
  2. Streptococcus spp (non-motile, non-spore-forming facultative anaerobic cocci)
  3. Clostridium spp (obligate anaerobes)

MYCOTOXIN MANAGEMENT WITH FEED ADDITIVES

More than 90% of animal feed is contaminated with mycotoxins, posing a significant threat to the health and performance of farm animals. These harmful metabolites are produced by fungi that infect crops both in the field and during storage, making them prevalent in almost all agricultural products worldwide. To address the risks of mycotoxins in farm animals and to prevent their transfer from contaminated feed to food of animal origin, Olus has developed the Elan®Tox feed additive portfolio.

MONOGLYCERIDES SUPPORT ANIMAL GUT HEALTH

In recent years, the escalating global concern over antibiotic resistance, particularly in animal agriculture, has prompted regulatory actions. The European Union and numerous other nations have implemented bans on the use of Antibiotic Growth Promoters (AGPs). In response to this issue, there is a pressing need for alternatives that are not only safe and easy to handle but also devoid of microbial resistance, especially in the treatment of various diseases in poultry and other animals.

EFFECT OF LYSOPHOSPHOLIPIDS ON BROILER PERFORMANCE WITHOUT ADDED DIETARY FAT

LYSOPHOSPHOLIPIDS (LPL)
Hydrolysed lecithin (lysolecithin) is the key active ingredient in Elan®Digest, created by an enzymatic process that transforms soy lecithin into lysophospholipids (LPLs). These lysophospholipids exhibit increased hydrophilicity and greater fluidity, significantly enhancing their capability to facilitate the formation of oil-in-water emulsions. The lysophospholipids in Elan®Digest have distinctive physical and chemical properties that have been observed to enhance nutrient absorption and optimise feed efficiency in various animal species. These benefits originat from the improved emulsification properties of lysolecithin over lecithin, leading to more efficient nutrient digestion, absorption, and utilisation by the animal. 

MATERIALS AND METHODS
  • 400 male Ross 308 broilers (starter weight 45.6 g) were distributed over 16 floor pens (25 birds/pen) placed in the middle of a commercial broiler house to simulate health and climate challenges similar to commercial practice. Wood shavings were used as bedding material.
  • A 3-phase corn/wheat/soya diet was used: starter, 0-14 days; Grower, 15-28 days and Finisher, 29-35 days of age with salinomycin as anticoccidial in the starter and grower diet. All birds received the same basal diet.
  • Treatments: the control group received a diet in which dietary fat was originated from vegetable sources, whereas the treatment group received the same diet with 500 g Elan®Digest/t (or 32 g LPL/t) on top.
  • The dietary fat level was 4.0%, 4.7% and 6.0% by using full fat soybeans. Additionally, 0%, 0.5% and 1.0% soybean oil was added to the different phases.
  • Measurements: production performance parameters (body weight gain, feed intake, feed conversion ratio and mortality) were measured per phase.
  • Feed and water were ad libitum available.

RESULTS

Production performance during the 35-day production period is given in Table 1.

 

 

 

 


*FCRc: FCR corrected for the average body weight (0.02/100 g BW)

Broiler performance was high, reaching a final body weight of 2’700 g at 35 days of age, whereas feed intake was over 3’800 g. Dietary supplementation with Elan®Digest had only a slight positive effect of final body weight (NS), but resulted in a significant improvement of the FCRc. A lack of effect on body weight gain was also shown in previous trials, which is due to the high dietary contents of digestible amino acids in the experimental diets. Although lysolecithin potentially stimulates the production of pancreatic proteases, an increased protein digestibility would not results in an improved body weight gain as amino acids in this trial were not limiting for growth. Elan®Digest did significantly reduce FCRc by 2,8 points. This confirms that lysolecithin improves fat utilization, resulting in improved feed efficiency when added on top, also in diets where dietary fat originates from vegetable feedstuffs.


CONCLUSIONS

Our research has shown that dietary supplementation with 500 g Elan®Digest/t to a wheat/corn/soy diet significantly improved feed conversion ratio of broilers during a 35-day production period. In this trial, dietary fat originated from corn and full fat soybeans. Given the current grain and fat prices, it is worth noting that the ROI of Elan®Digest remains very high at 5.5:1.

SAVE FEED COSTS WITH HYDROLYSED LECITHIN

Over time, advancements in broiler breeding have enhanced the growth potential of chicks, enabling them to grow more rapidly and utilize dietary nutrients more efficiently. The key to realizing the genetic potential of broilers lies in optimizing farm practices and diets. Formulating these diets involves the incorporation of substantial levels of fats, which need to be effectively emulsified to maximize their utilization by the birds. Hydrolysed lecithin, also known as lysolecithin, emerges as a promising solution for reducing dietary fat levels or replacing costly fat sources with more affordable alternatives. Hydrolysed lecithin produced by Olus, not only lowers expenses but also supports animal health and maintains productivity.
