RFCs boost egg production efficiency
New research1 demonstrates the ability of Refined Functional Carbohydrates™ (RFC™) to positively impact egg production efficiency.
RFCs are the components harvested from yeast cells (S. cerevisiae) using specific enzymes during the manufacturing process. This enzymatic hydrolysis yields MOS (Mannan Oligosaccharides), (1,3-1,6) beta glucans and D-Mannose.
These compounds are naturally present in all yeast cells, but are not readily bioavailable. The method of processing used to refine the yeast cells influences the size and structure of these liberated components which, in turn, affect bioavailability and functionality. Research2,3,4 shows that each RFC has a specific mode of action and outcome when fed to livestock.
CELMANAX™, sold as AVIATOR™ in certain international markets, is a unique feed additive containing RFCs and is designed to improve overall health, growth and feed conversion in poultry. Multiple studies in broilers show these benefits to be consistent.
But what impact does it have for layers?
Researchers recently set out to determine if AVIATOR can offer the same efficiency benefits for layers. And they explored how well it compares to some other common feed additives.
The study was conducted in Guatemala and featured 200 Lohman White Classic layers at 28 weeks of age. The birds were allotted into five treatments in a completely randomized block design. The 10-week study included four birds per cage, with eight replications per treatment.
The birds were give a two-week adaptation period that was followed by eight weeks of data collection. A basal layer diet was formulated to meet the strain of egg-type chicken used. Water via two nipple drinkers per cage and mash feed prepared at a commercial feed mill was provided. In addition, 14.5 hours of total light (3.5 hours of artificial light) was provided during the study.
Data showed that AVIATOR results were excellent compared to some of the other competitors. AVIATOR was very good at improving both egg production efficiency as well as improving some of the egg parameters, supporting its application in the layer industry very well.
In addition, results also showed:
Therefore, we are able to conclude that AVIATOR fed to layers resulted in the largest improvement in layer performance while improving some egg parameters compared to other feed additives tested.
