Additional guidelines

The Revista Brasileira de Zootecnia does not publish articles resulting from experiments involving the use of products prohibited by the Ministry of Agriculture, Livestock and Supply for feeding animals destined for consumption:

- chicken bed and byproducts of animal origin in ruminant feeding: According to the Normative Instruction number 8 from the Ministry of Agriculture, Livestock and Supply of March 3, 2004, it is prohibited, throughout the Brazilian territory to use chicken bed and by products containing proteins and fats of animal origin in the feeding of ruminant animals.

- antibiotics and growth promoter additives: it is forbidden to use antibiotics as growth promoters in products destined for animal feeding (Portaria nº 193 de 12/05/1998).

NIDN and NIDA determination: the results of analyses regarding insoluble nitrogen in neutral detergent (NIDN) and insoluble nitrogen in acid detergent (NIDA) should be expressed in percentage of the total nitrogen, and not in percentage of the dry matter.  The same is valid for their correspondents, that is, insoluble protein in neutral detergent (PIDN) and protein in acid detergent (PIDA).

Crude fiber in studies on ruminants: the CF and ENN data (obtained by difference) of fibrous materials (grasses, legumes, straw and mulch, etc.) have errors in the procedures built in to the results.  The CF analysis refers only to the recovery of cellulose and insoluble lignin in alkali. ENN, obtained by difference, attracts all the error of the procedure, that is, sugars, starch, hemicellulose, pectin and alkali soluble lignin.  CF and ENN have no significance in studies on ruminants.

Article mergers:

§  studies of the same authorship, carried out in the same experiment and on the same subject (companions or in series), should be analyzed by the same reviewers, when it is not the case of a merger.

§  articles involving non-ruminant and ruminant performance (intake, weight gain and food conversion) and digestibility should be presented in the complete form, not divided in two.

§  studies on non-ruminant and ruminant nutritional requirements should include the data for the growth and finishing phases, and they should not be published separately.
