additives in animal nutrition

مرسلة بواسطة migha

SUMMARY
The aim of this Regulation is to establish a standardised procedure for authorising the placing on the market and the use of feed additives and to lay down rules for the labelling and supervision of these substances.
Scope
These rules apply to all feed additives * except processing aids * and veterinary medicinal products as defined by Directive 2001/82/CE , with the exception of coccidiostats and histomonostats used as feed additives. This Regulation thus complements Community legislation prohibiting antibiotics by providing for the four antibiotic additives still on the market in the EU to be phased out as of January 2006: monensin sodium, salinomycin sodium, avilamycin and flavophospholipol.
Authorisation procedure
To be legally placed on the market and used, feed additives must be authorised by the European Food Safety Authority (EFSA). Applications are submitted to the Commission, which informs the Member States and forwards the application to the EFSA. The application must include certain information, such as the name and address of the applicant, a description of the method of production, manufacturing and intended uses of the additive, proposed conditions for placing the additive on the market, etc. In addition to this application, the applicant must send samples to the Community Reference Laboratory for analysis. The EFSA may ask for further information.
The additive is authorised only if the applicant can prove that:
the additive has a favourable effect on the characteristics of the feed to which it is added or on animal production;
the additive does not have a harmful effect on animal health, human health or the environment;
Based on the EFSA opinion, the Commission decides whether or not to authorise the additive. For products authorised under Directive 70/524/EEC, together with urea and derivatives, and any amino acid, salt of an amino acid or analogous substance listed in points 2.1, 3 and 4 of the Annex to Directive 82/471/EEC, an authorisation application in line with this Regulation must be submitted either one year before the expiry date of an authorisation given for a limited period pursuant to Directive 70/524/EEC, or seven years after the entry into force of this Regulation for additives authorised without a time limit or pursuant to Directive 82/471/EEC.
This Regulation contains provisions concerning the use of non-authorised additives for research purposes and provisions concerning the use of certain additives (in particular those produced from genetically modified organisms).
Persons using an authorised additive or placing it on the market are responsible for ensuring compliance with any conditions or restrictions imposed by the Commission.
Based on the EFSA opinion, the Commission may decide to amend, suspend or revoke an authorisation.
Information on additives
The additives are entered in a register made available to the public. They are allocated to one or more of the following categories: technological additives; sensory additives; nutritional additives; zootechnical additives; coccidiostats and histomonostats. Additives must be labelled clearly and indelibly and include certain information, including the specific name given to the additives upon authorisation and their identification number, the name and address of the person responsible for these particulars, the net weight or net volume of the additives, directions for use and any safety recommendations regarding use and, where applicable, the specific requirements mentioned in the authorisation.
Cats and Dogs Nutrition
Advances in veterinary medicine have resulted in vaccination programs that protect dogs and cats from many life-threatening diseases and in medical procedures that contribute to lengthened lifespans. Likewise, progress in the field of nutrition has generated an improved understanding of canine and feline dietetics and led to the development of well-balanced pet foods that contribute to long-term health and aid in the prevention of chronic disease.
Today's competitive market contains a vast array of foods, snacks, and nutritional supplements for dogs and cats. These products are sold in grocery stores, feed stores, pet shops, and veterinary hospitals. Products vary significantly in nutrient composition, availability, digestibility, palatability, physical form, flavor, and texture. Some foods are formulated to provide adequate nutrition throughout a pet's lifespan, while other foods have been marketed specifically for a particular stage of life or a specific disease state. This large selection of commercial products, combined with the periodic propagation of popular nutritional fads an fallacies, has resulted in much confusion among pet owners and companion animal professionals regarding the nutritional care of dogs and cats.
A basic understanding of the fundamental basics of nutrition is a necessary prerequisite for evaluating pet foods and making decisions about a pet's nutritional status. The term nutrition refers to the study of food and the nutrients and other components that it contains. Energy, water, carbohydrates, fats, proteins, vitamins, and minerals are examined in detail. Subsequent sections address the specific nutrient requirements of dogs and cats, the types and compositions of pet foods, feeding management throughout the life cycle, feeding problems, and the management of nutritionally-responsive diseases. Information contained in this section will enable pet owners, students and companion animal professionals to make informed decisions about the diets and nutritional health of dogs and cats throughout all stages of life.
