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.2021

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.2021

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.2021

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 throughout life.2021

Active vitamin D3-glycoside preserves weight gain and modulates the inflammatory response in broiler chickens challenged with lipopolysaccharide
Keeping laying hens up to 100 weeks of age (producing 500 eggs) without moulting is no longer an utopian idea. Such long production periods require new tools to support the hen to produce high quality eggs until the end of the laying cycle. Maintaining good eggshell quality is especially crucial. Independent of egg weight, the eggshell weight and therefore the amount of calcium (Ca) deposited remains more or less constant over time.2020

Bone characteristics of broiler chickens fed diets supplemented with Solanum glaucophyllum
The aim of this study was to assess the characteristics of the tibiotarsus of male broilers at 21 and 35 days of age. The percentages of collagenous proteins (CP), non-collagenous proteins (NCP), ash, and minerals (calcium, phosphorus, potassium and sodium), as well as weight of dried and defatted tibiotarsus in natura were determined.2016

1,25-dihydroxycholecalciferol from Solanum glaucophyllum supports normal growth and reduces the negative effects of calcium and phosphorus restriction on broilers’ bone tissue
Feed supplementation with 1,25-dihydroxycholecalciferol (1,25(OH)2D3) has been studied as a means to decrease the incidence of bone abnormalities in broilers and reduce dietary inclusion of calcium and phosphorus. The objective of this research was to determine the optimal level of feed supplementation with 1,25(OH)2D3 from Solanum glaucophyllum for growing broilers …2018

Consequences of genetic selection on metabolic regulation of skeletal health in broiler chickens
Improvements in broiler growth performance resulting from commercial selection are associated with poor skeletal health. Vitamin D3 plays an important role in Ca and P homeostasis and is essential for bone strength. Several studies have demonstrated that feeding biologically active metabolites of D3 [25(OH)D3 and 1,25(OH)2D3] can improve bone health.2019

Efficacy of orally administered Solbone®, an herbal source of metabolic active vitamin D, in piglets
The multiple biological effects of vitamin D are still the object of intensive research. It is critical not only for the homeostasis of calcium, phosphorus and magnesium but also for skeletal structure, immune response and performance. Pigs are able to synthesise sufficient vitamin D on their own when having outdoor access.2019

Herbal vitamin D metabolite facilitates parturition in sows
Introduction Modern pig farming is associated with high piglet mortality. The duration of farrowing is critical and has an impact on survival and subsequent thriving of the piglets. Since tedious labour caused by weak muscle tonus is linked to blood calcium level, it was thought that increasing Ca in the sows´ diet might improve the reproductive performance.2018

1,25-Dihydroxyvitamin D3-glycoside of herbal origin exhibits delayed release pharmacokinetics when compared to its synthetic counterpart
Vitamin D requires two metabolic steps to become biologically active. In a first step 25-hydroxyvitamin D3 is formed, which acts as storage form. After a tightly controlled step in kidney the active metabolite 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) is formed. Because kidney is the relevant metabolic organ for this conversion, 1,25(OH)2D3 needs …2013

Vitamin D and the Immune System
It is now clear that vitamin D has important roles in addition to its classic effects on calcium and bone homeostasis. As the vitamin D receptor is expressed on immune cells (B cells, T cells, and antigen-presenting cells), and these immunologic cells are all capable of synthesizing the active vitamin D metabolite, vitamin D has the capability of acting in an autocrine manner in a local immunologic milieu.2011

Disorders of Cholecalciferol Metabolism in Old Egg-Laying Hens
It has been reported that the rate of cracked or soft-shelled eggs markedly increases in old laying hens. We investigated the effect of age on cholecalciferol metabolism in different age groups of laying hens. The egg production rate in hens more than 500 days old was maintained within a range of about 70% of that in young hens (230-320 days old), whereas the rate of cracked or soft-shelled eggs increased markedly with age. When kidney homogenates from the different …1982

Maintaining successful performance in the older laying hen
Calcium (Ca) is the most abundant mineral in an organism and up to 95% of it can be found in bones. In birds, Ca additionally plays a crucial role in egg shell formation. Ca-metabolism in birds has to be in perfect working order, independent of whether the egg weighs 2.5kg (ostrich), 500g (kiwi bird; 15-20% of the female BW) or less than O.Sg (certain hummingbirds).2018

Waxy-leaf nightshade: an additional tool to help raise large litters
How to ensure that piglets born into large litters survive and thrive until weaning is one of the main challenges in pig production today. Although the number of piglets born has markedly increased in recent years, the number of piglets weaned could not keep up and is lagging behind. This is not only an economical loss but also raises concerns regarding animal welfare.2018
