Article
Amino acids (AAs) are an abundant class of nectar solutes, and they are involved in the nectar attractiveness to flower visitors. Among the various AAs, proline is the most abundant proteogenic AA, and γ‐amino butyric acid (GABA) and β‐alanine are the two most abundant non‐proteogenic AAs. These three AAs are known to affect insect physiology, bein...

Trace element status and metabolic milieu are sometimes overlooked in common veterinary clinical practice across animal species. The evaluation of requirements of trace elements, in fact, may be useful to prevent the perturbation of tissue-specific metabolic impair. In particular, essential trace elements in the diet play key roles within sub-cellu...
Article
Hydrolysable tannins are polyphenolic molecules contained in plant foodstuffs, potentially toxic for animals. Since tannins have been found in some bee products such as bee pollen, propolis, and honey, this work aimed to test the effects of tannins dietary assumption on bees’ health. Results showed that supplementation of honey bees diets with 0.05...

The pattern of selected metabolites for interpreting homeostasis during the growth of foals can be used as an indicator of energy balance state and liver health. Against this background, the literature on circulating parameters of foals across growth stages is scanty. We hypothesized that circulating metabolites indicating energy distribution such...

The Food and Agriculture Organization’s previsions show that by 2050 the world’s population will reach 9.6 billion people, and the request for a high value protein source will increase as well. Poultry can guarantee high value protein for humans, even in the poorest regions of the world. Hence, efficient poultry production is needed, matching with...

Cultivation of buckwheat (Fagopyrum esculentum Moench) under Mediterranean photothermal conditions could affect synthesis of the flavonoid rutin and its partitioning within the plant, thus affecting the nutraceutical value of plant products. We examined rutin concentration and yield in the forage and the grain of common buckwheat grown under Medite...

Aim of this study was to evaluate the effects of a carbohydrate-based diet on serotonin blood concentrations in phobic dogs. For this study were recruited, from a public shelter, three dogs (2 neutered females and 1 male), weighing between 15 and 30 kg and living in the shelter for more than six months. Dogs received by a veterinary behaviorist a d...

Milk has a complex highly variable nutritional com-position based on the different species and animal breeds, together with the strategy and management of the animal feed. It is the first food consumed by children, exclusively for the initial months because it contains all the nutrients necessary for body growth and the development of cognitive fun...

The content of rutin and quercetin was examined in fresh, hayed and ensiled forage of common buckwheat. The treatments were two varieties of buckwheat, ‘Bamby’ and ‘Lileja’, and two ripening stages of harvest, first green and first brown achenes. In the silage, produced with experimental mini-silos, additional treatments were the wilting of the for...

Introduction: Creatine (Cr) is widely used as supplement in human athletes. Its effect is to increase the muscle storage of phosphocreatine (PCr) and enhance the restoration of adenosine triphosphate (ATP) during short and high-intensity exercise. Anaerobic energy release results in depletion of phosphocreatine and accumulation of lactic acid, whic...

For its nutritional composition, donkey milk is an excellent alternative to breast milk for infants suffering from cow’s milk allergies. Even in donkeys, a passage of aflatoxin from contaminated feed to milk could occur, as reported by many authors in other dairy species, but there are no studies on this topic. This work was aimed at studying the e...

Two experiments were carried out in 2013/2014 in order to evaluate the forage yield and the nutritional value of the fresh, hayed and ensiled common buckwheat. Two varieties were harvested at the Green and Brown achene stages. The silage was produced in experimental mini-silo. The need for wilting the forage (at 35% dry matter) and for adding Lacto...

Pea (Pisum sativum L.) and Faba bean (Vicia faba L. var. minor) are valuable sources of protein and energy for monogastric animals, traditionally cultivated in the Mediterranean area. They can partially or even totally replace soybean meal, that is very expensive and often derived from GM plants. The aim of this study was to evaluate some immunolog...

The ration of performance horse usually includes great amount of cereals. Nevertheless there is a limit to the amount of starch which a ration should contain. Addition of dietary fat to improve the caloric density of horse mixed feed is a common practice. Fat supplement reduces the negative effect of excessive starch fermentations in large intestin...
