Uniformity of laying flocks: what role can plant extracts play?

Uniformity

issues for pullets, layers and breeders

In all animal production sectors, flock uniformity is an important criterion. In the laying hens industry, a homogeneous egg size is sought after, but above all, it’s a level of performance in terms of laying rate and egg mass produced that everyone is looking for. And behind these last 2 criteria lies the notion of homogeneity.

In fact, for the best laying rate or the highest egg mass produced, each hen needs to be fed a feed whose nutritional composition matches to her physiological needs. However, physiological requirements evolve and depend on the hen’s physiological age (live weight in the case of pullets), not its actual age. In a heterogeneous flock, there is no winning choice: adapting the feed to the majority disqualifies the production of the others; keeping high feed specifications means higher production costs and a risk of exhaustion for the most advanced animals.

Moreover, once a herd starts to show signs of heterogeneity, it's often difficult to correct the deviation.
This is why the uniformity of layer batches right at the start of laying is a criterion that needs to be monitored very closely.

How to get around the variations of plant extracts?

The origin of these variations
Plant extracts still have a reputation for being too variable. This is undoubtedly because additives of very different types are being evaluated:based on crushed plant parts, essential oils, oleoresins, or even simple synthetic molecules. These 4 types of products do not have the same level of standardization, which explains much of the variability of results in the field. Oleobiotec Poultry is a unique product based on standardized essential oils and spices oleoresins.

Pullets and laying hens

Egg production has a long production cycle. The first stage of layers’ growth is crucial for a good laying start later on. After that, the entire laying period is critical and the better use the layer makes of the feed, the better the animal’s well-being and productivity will be. Feed efficiency and the balance of the microbiota throughout the production cycle are therefore essential, both for the animal and for the farmer.

What are the benefits of Oleobiotec ?

  • 2.8% increase in feed efficiency
  • Better egg quality: reduction of downgraded eggs (-20 to -30%)

Broilers

Broiler poultry farming is very much driven by production costs. Feed efficiency is the main indicator observedOleobiotec poultry exploits the gut microbiota-brain axis to greatly improve feed efficiency and thus contribute to lowering production costs and increasing the value of broiler products.

What are the benefits of Oleobiotec ?

  • 2.8% increase in feed efficiency

Oleobiotec is a range of sensory products based on exclusive synergies between essential oils and spice extracts (oregano, thyme, cinnamon, ginger, pepper, etc.).

Why use Oleobiotec?

Feed intake efficiency is one of the main factors that determine the overall efficiency in livestock farming. Oleobiotec helps to improve feed efficiency. 
Each animal is host to a powerful microbiota. The Oleobiotec range is designed to support the microbiota, keeping it regulated and thus promoting “better-being” through the gut microbiota-brain axis. 
Essential oils are sensory active ingredients that are perceived through the olfactory and gustatory senses, in direct link with the brain (palatability). In addition, essential oils, such as thyme or oregano, are known to play a role in the microbiotapromoting balance and diversity (Allaoua et al. 2018; Allaoua et al. 2022). Spices, on the other hand, stimulate proper digestive functioning such as gastric motility and the release of digestive enzymes.
