Activated vitamin D: Connecting parents and offspring

Good chick quality and the number of fertile settable eggs per hen housed are the main drivers in broiler breeder operations. Apart from incubation conditions, successful hatchability depends on many factors related to eggshell quality (for example strength, porosity and absence of microfractures).

Understanding the lack of 1,25(OH)2 vitamin D3 in aged laying hens

During the last decade, great progress has been made on the laying persistency of white and brown laying hens. As a result, there is an increasing number of flocks that pass the ‘500 eggs milestone’ in many countries. This milestone is better known as ‘500 eggs per hen housed without moulting’.

Herbal vitamin D metabolite helps the farrowing process

With the increasing prolificity of sows it becomes essential to adjust nutrition to cover the needs of modern breeds. An important nutrient is vitamin D, as it is a key factor in calcium (Ca) and phosphorus (P) metabolism. The mineral requirement of sows is very high from the third part of gestation until the end of lactation.

Getting the balance right: the underestimated weight of dietary calcium

The macronutrient calcium (Ca) is mostly known for its crucial role in bone mineralisation and bone strength. Containing 99% of the body Ca reserves, the skeleton is the major storage site for Ca. Besides maintaining skeletal integrity, Ca is important for muscle contraction, neuronal transmission, intracellular signalling and many other functions.

A beat of science 004: Heat stress in laying hens

The combination of high ambient temperatures and high humidity is a well-known external stressor in livestock production. Layers are particularly sensitive to heat stress, because of daily egg and eggshell production.

Vitamin D3 and its metabolites in sow fertility and performance

The number of piglets born alive, litter size at birth, and the number of weaned piglets per sow per year are reproductive traits with great economic impact on the profitability of pig production. Achieving high farrowing rates throughout the sow’s life, along with litter uniformity, are great challenges in high prolific sows.

Natural vitamin D3 metabolite supports bone health of laying hens
Proper skeleton calcium (Ca) stores is key to reduce bone disorders. Early sexual maturation, alongside production of the first egg at a younger age, fast increase to peak production and improved laying persistency, has increased the demand for proper skeletal Ca stores at the start of egg production. Only then can bone and shell quality be maintained …

Solanum glaucophyllum in layer hen diets to reduce dietary phosphorus

Modern laying hens have a huge potential to produce affordable and high quality animal protein. In current practice, layers can produce over 500 eggs per hen-housed, whereas the potential of certain genetics under optimal conditions is already at least 30% higher.

Vitamin D3 metabolite 1,25(OH)2D3 and immune response in broilers

As antibiotic-free broiler production, often even including ionophore coccidiostats, is becoming more common, the immunocompetence of birds becomes increasingly important. One way to achieve this is to modulate and support the immune system to increase disease resistance of the animals.
