Are probiotics in poultry
production still effective?

articles/36066
analyzing gut and environmental samples, molecular work is
done to analyze the microbial community to better understand
the presence of beneficial and pathogenic bacteria that affect
the bird's ability to defend itself against disease challenges. 
A tailored solution is developed for a farm using Arm
& Hammer's proprietary Bacillus as a feed additive. The
program is sometimes supplemented with a Lactobacillus
and Bacillus combination product administered in the
drinking water during times of stress. Ongoing monitoring of
the farm's microbiome is offered to continue to better understand the changes after starting a new probiotic program.

Enzyme combinations with probiotics
Well-studied feed enzymes are generally classified as
nutritional products and are commonly used to improve
the digestibility of feed ingredients. Emerging research
is pointing also to the possible prebiotic activity of
some enzymes. Manufacturers are offering products
combining multiple enzymes or enzymes and probiotics in standard and customized products, which merit
mentioning as new alternatives. 
Enzymes have very unique modes of action, so specific
feed formulations may require different combinations and
levels for optimum benefits. Several newer enzymes are
on the market offering more choices to handle specific
feed formulation challenges. Enzyme combinations with
probiotics offer even more alternatives, which make field
evaluation more challenging with two or more active
ingredients. Most research is manufacturer generated and
the proliferation of products further complicates assessing
their real potential. ■

AVIARY
with MIDDLE NEST

The Specht aviary system with nests in the middle
is a further development of laying batteries and floor
management system that Specht has been producing
since 1967.
Good reasons for the Specht Varia system with middle nest:
>> Optimum stocking density per house because of usable
area on several levels.
>> Integrated LED-lights in the system.
>> Group laying nest in the middle with nipple drinking lines.
>> Little mislaid eggs due to the highest possible
acceptance of the nests by the layer hens.
>> Automatic manure removal with PP-belts.
>> System with a good overview and more space per hen.
>> Arm length (90 cm) up to the middle.
Useable space on several levels enables an optimal
stocking density. The use of floor space contributes
to animal-friendly husbandry.
