Juarez Donzele ; Yes, UCP and corticosterone determinations are important elements for understanding negative consequences of commercially-relevant stresses. However, it is generally accepted that at the cellular level most of stresses are associated with overproduction of free radicals and oxidative stress. Therefore? activation of vitagenes responsible for stress adaptation is considered as a ne ...

The recommendations (The vitagene-regulating mixture called PerforMax) are used in many different countries and at various poultry (broilers, breeders, layers, etc.) and pig farms

1. Supplying extra nutrients with feed in stress conditions is problematic, since feed consumption is decreased 2. Organic minerals can have protective effects only in the case of their dietary deficiency. However, major commercial poultry and feed diets are not Zn, Cu or Mn-deficient. 3. Organic Se can be beneficial. 4. My whole idea is to develop a system of quick response to stress conditions. ...

Yes, by using carnitine as a part of antioxidant strategy it is possible to improve antioxidant defences piglets in early postnatal development

Dear Juarez, carnitine can improve mitochondria integrity in stress conditions, including heat stress. Since mitochondria are the main source of free radicals in the cell, carnitine can decrease oxidative stress. Furthermore, carnitine can also affect Nrf2 activity and by doing so further increase antioxidant defences

Introduction L-carnitine (LC) is a naturally occurring and widely distributed in nature compound. It was discovered in 1905 in Liebig’s meat extracts, a popular ‘dietary supplement’ at that time, by Gulewitsch and Krimberg [1] who named the substance from the Latin word for flesh (“carnus”). Carnitine chemical structure was established in 1927 and its function was re ...

Thank you for comments, I would like to stress the following: 1. Organic minerals will not solve the problem of the stress, their supplementation is effective only in the case of dietary mineral (Zn, Mn, Cu, Se) deficiency. If the diet is adequate in these minerals, there would not be much response in terms of antioxidant enzyme synthesis. The technology of supplying special vitagene-regulating m ...

1. Introduction Breeding programmes are designed to produce a broiler with high potential for growth, yield, and feed efficiency. These traits may compromise health status under husbandry designed to maximise this genetic potential, since there is a trade-off between growth- and health-related traits with responses to husbandry programmes, age, sex, and genetic line (Siegel et al., 2001). In thi ...
