identified and characterized

▪ Fat soluble vitamins (4):

▪ vitamin A (retinol) vitamin D (calciferols)

▪ vitamin E (tocopherols) vitamin K (phylloquinone)

▪ Water soluble vitamins (9):

▪ vitamin B1 (thiamin) vitamin B2 (riboflavin)

▪ vitamin B6 (pyridoxine) vitamin B12 (cobalamin)

▪ niacin (B3;PP) pantothenic acid (B5)

▪ folic acid (B9; M) biotin (B7; H)

▪ vitamin C (ascorbic acid)

VitaminsClassification and Nomenclature

▪ Choline is sometimes included in the list;

▪ Inositol is essential for aquatic species only

▪ Vitamins are essential micronutrients, required for optimum

health and normal physiological functions such as growth,

development, maintenance or reproduction of the animal.

▪ Vitamins exercise catalytic functions; they facilitate both

synthesis and degradation of the nutrients, thereby controlling

the metabolism.

▪ Most vitamins cannot be synthesized by the animals and

therefore they must be obtained from the feed.

Vitamins: Definitions and Functions

Functions of VitaminsVitamin Basic function(s) Deficiency disorders/diseases

Vitamin A photosensitive retinal pigment, regulation of epithelial cell

differentiation, regulation of gene transcription

blindness, xerophthalmia,

keratomalacia, impaired growth

Vitamin D promotion of intestinal Ca absorption, mobilization of Ca from

bone, stimulation of renal Ca resorption, regulation of PTH

secretion, possible function in muscle

Rickets, Osteomalacia

Vitamin E antioxidant protector for membranes nerve, muscle degeneration

Vitamin K co-substrate for γ-carboxylation of glutamyl residues of several

clotting factors and their Ca-binding proteins

impaired blood clotting

Vitamin B1 coenzyme for oxidative decarboxylation of 2-keto acids,

coenzyme for pyruvate decarboxylase and transketolase

Beriberi, polyneuritis, Wernicke-

Korsakoff syndrome

Vitamin B2 coenzyme for numerous flavoproteins that catalyze redox

reactions in fatty acid synthesis/degradation, TCA cycle

dermatitis

Vitamin B6 coenzyme for metabolism of amino acids symptoms vary by species

Vitamin B12 coenzyme for conversion of methylmalonyl-CoA to succinyl-

CoA, methyl group transfer from 5-CH3-FH4 to homocysteine in

methionine synthesis

megaloblastic anemia, impaired

growth

Pantothenic

co-substrate for activation/transfer of acyl groups to form

esters, amides, citrate, triglycerides, etc.

symptoms vary by species

Niacin co-substrate for hydrogen transfer catalyzed by many

dehydrogenases, e.g. TCA cycle respiratory chain

Pellagra

Folic Acid coenzyme for transfer of single-carbon units megaloblastic anemia

Biotin coenzyme for carboxylations dermatitis, cracked hooves

Choline component of acetylcholine and the membrane structural

component phosphatidylcholine

poor growth, Perosis (deformity of

leg bones in young birds), fatty

Vitamin C co-substrate for hydroxylations in collagen synthesis, steroid

metabolism

Scurvy

• Vitamins can almost never be regarded as nutrients in isolation

given that they display a wide range of interactions

▪ Fat soluble vitamins must be fed in correct ratios as they all

compete for intestinal absorption

▪ Water soluble vitamins are regulators of the intermediary

metabolism of protein, fats and carbohydrates (energy): a lack

of one of them increases the need of the others

• It’s very difficult to estimate precisely the optimum

requirements for maximizing performance for each vitamin

separately and mathematical relationships can’t be established

Factors influencing Vitamin Requirements

Comparison of Ross broiler live weight for age over time (as hatched)

Source: Ross Performance and Management Guide, 1980, 2007 and 2014

Genetic driven improved performance requires each year

an adjustment of vitamin supplementation in the range of 1%

The improved efficiency reduces vitamin intake per unit of productivity

and dictates the need for more dietary vitamin

Vitamin Deficiencies in Poultry

▪ Inadequate vitamin intake with the feed:

▪ low natural vitamin levels in feedstuffs, low availability

▪ presence of vitamin antagonists (avidin [egg white] biotin)

▪ insufficient vitamin supplementation levels / mixing errors.

▪ Poor digestion and absorption of vitamins

▪ gut health issues impair fat soluble vitamins absorption

▪ Increased vitamin requirements:

▪ depending on diet composition (e.g. vitamin E for PUFA’s)

▪ for immune response and during phases of stress or diseases.

Vitamin D3 and 25OHD3 studies on meat yield

▪ Birds:

▪ 1440 Cobb broilers ; 0-42days

▪ Treatments:

▪ 4 treatment groups

▪ 12 replications per treatment

▪ 30 broilers per pen

▪ Parameters measured:

▪ Serum 25OHD3 at 21d and 42d

▪ BW, FCR at 21d and 42d

▪ Breast meat yield at 42d

▪ 50 birds/treatment

▪ Expression of protein synthesis-related genes

(mTOR, S6K-1 and IGF-1 ) at 42d

• mTOR (mammalian Target of Rapamycin) is a protein-

kinase important for cell growth and proliferation.

• Its activation is dependent on the effect of hormones or

specific nutrients (Aas)

• Both mTOR and S6K are genes connected with protein

synthesis

Vitamin fortification of eggs

Vitamin Potential increase & comments

Vitamin A 2-3 fold

Vitamin D3 6 to 10 fold attainable in 2-3 weeks

25OHD3 Naturally present in egg yolk of hens receiving vitamin D3

(0,5 to 8,1 mcg/100 g whole egg)

3-4 fold increase

Vitamin E 4 fold or more increase in 2 to 3 weeks (e.g. 200 IU/kg

feed from 119 to 606 IU/kg egg yolk)

Vitamin K Nearly 5-fold increase in hens fed 7,5 mg/kg feed

Folic acid 2-3 fold increase in 2 to 3 weeks

Biotin 3-5 fold; excess largely goes into albumen

Vitamin B12 3-4 fold; good response but high feed levels needed

Vitamin B2 2-3 fold but fairly refractory to accretion at high feed levels

Pantothenic acid 2-3 fold; plateaus quickly

Niacin 2-3 fold; limited data base

Vitamin B1 ≈2 fold; limited data base

Vitamin B6 ≈2 fold; very limited data base

▪ Vitamins are essential nutrients, required in very small amounts,

playing a pivotal role in all metabolic and physiological functions

Take Home Message

▪ Vitamins have a pretty limited feed cost impact but a great

responsibility in animal’s health and performance as well as on

quality of animal origin foods

▪ Vitamins, besides a direct impact on DWG and FCR, can modulate

several physiological aspects like immunity and stress and hence

providing indirect performance benefits e.g. reduced medications
