There has been an increase in vitamin A fortification of livestock feeds resulting in increased residual vitamin A in organ meats, which are often used in canned dog foods. The effect on bone density of feeding various concentrations of vitamin A in a canned dog food product was investigated. Thirty-two random-source dogs were assigned to four treatments in a randomized complete block design. The diets contained 15,000, 50,000, 116,000, or 225,000 IU vitamin A/1,000 kcal ME. Diets were fed up…

Nutrition and the skeletal health of dogs and cats

It is remarkable that moderate increased vitamin D supplementation decreases the detrimental influence of excess vitamin A on liver fibrosis, but not on the skeleton, possibly due to the anti-fibrotic effect of moderate vitamin D.

Vitamin A and Bone Health

Vitamin A seems to have a relatively narrow optimal dosage window with low and high intakes associated with negative effects, especially in elderly persons, and in the elderly the balance which ensures a sufficient retinol intake and simultaneously protects against excessive supplementation, is very delicate.

Energy intake, growth rate and body composition of young Labrador Retrievers and Miniature Schnauzers fed different dietary levels of vitamin A

The data show that energy intakes of puppies particularly during early growth are highly variable; however, the growth pattern and body composition of the LAB and MS breeds are not affected by the intake of vitamin A at levels up to 104·80 μmol retinol (100 000 IU vitamin A)/4184 kJ (1000 kcal).

An Insight into the Role of Vitamins other than Vitamin D on Bone

Existing information supports vitamin C and K to play a role in bone formation and calcification and there is very limited data supporting the favorable effects of vitamin A.

The distribution of vitamin A and retinol-binding protein in the blood plasma, urine, liver and kidneys of carnivores.

The levels of vitamin A in the livers of raccoon dogs and silver foxes were extremely low, which would be interpreted as a sign of great deficiency in humans, and the high levels in the kidneys in all three species may indicate a specific function of the kidney in the vitamin A metabolism of canines.

The metabolism of both calcium and vitamin D is reviewed, and the nutritional deficiency and excess syndromes that can lead to an imbalance of one or the other of these nutrients are reviewed.



Vitamin A concentrations in commercial foods for dogs and cats.

The vitamin A concentration was determined in 89 Australian brands of commercial foods for dogs and cats. It was found that 8% of the dog foods and 14% of the cat foods had concentrations of vitamin

Survey of animal livers for vitamin A content.

Retail samples of livers from calf, ox, lamb, pig, chicken, pig and turkey were analysed to determine levels of vitamin A and to aid assessment of the effects of using vitamin supplemented compound feedingstuffs for livestock.

Results after precipitation and ultracentrifugation indicate that similar carrier proteins may exist for retinol, retinyl esters and alpha-tocopherol in the urine.

Evaluation of vitamin A toxicity.

An identifiable fraction of the population surveyed consumes vitamin A supplements at 25,000 IU/d and a few individuals consume much more, while beta-Carotene is much less toxic than vitamin A.

On the basis of findings in this cat, hypervitaminosis A should be suspected in any sick cat fed a diet consisting partly or completely of raw liver.

Dietary protein and(or) energy restriction in mares: plasma glucose, insulin, nonesterified fatty acid, and urea nitrogen responses to feeding, glucose, and epinephrine.

Sixteen light horse mares were fed Bermudagrass hay and a corn/cottonseed hull-based supplement formulated to contain either 100% (control) or 50% (restricted) of the protein and(or) energy requirements for maintenance in a 2 x 2 factorial arrangement of treatments.

The pattern of bone growth is determined by epiphyseal-cartilage activities for which vitamin A is as essential, apparently without the intermediation of other organs, as it is in vision.

Quantitative CT for determination of bone mineral density: a review.

The author reviewed this literature to provide both the historic perspective and current status of BMD measurement with CT, the physical and physiologic bases of the method, accuracy, reproducibility, radiation dose, and clinical utility.

Vitamin A-responsive dermatosis in the dog.

In 3 dogs, focal, well-circumscribed skin lesions compatible clinically with seborrheic dermatitis responded to oral treatment with vitamin A, and seven other dogs with similar lesions but with histopathologic findings not compatible with phrynoderma or follicular keratosis did not respond to vitamin A therapy.

Bone Remodeling After Leg Lengthening: Evaluation with Plain Radiographs, and Computed Tomography and Magnetic Resonance Imaging Scans

Ten patients who had undergone leg lengthening were monitored with plain radiographs and computed tomography scans at 3-month intervals and when the external fixator was removed, MRI scans could not demonstrate any continuous fat signals in the lengthened region, suggesting the lack of medullary cavity.
