These poisons can be found in grain seeds, linen, nuts, and feedstuff of ambush, if cows pasturage from infected food, aflatoxin B1 (AFB1) hydroxylase by the hepatic enzyme of cytochrome P450 and changed to aflatoxin M1 (AFM1).
The ADC values (Table 1) obtained in hybrid striped bass fed with the pike perch diet (and in those fed the two trout diets) are in the lower range of ADC values for feedstuff of animal origin previously reported for hybrid striped bass (Sullivan and Reigh 1995).
This result illustrates the crucial importance of the selection of feedstuffs for FMR and fish oil, since the NOFM diet did not receive amino acid supplementation.
A collaborative study has been carried out in four laboratories (UPV, UPM, CLO, INRA) with the aim of comparing different evaluation methods of feedstuffs for rabbits.
In a study of feedstuffs for horses by Wolf et al. [ 46], 47 % of oats samples and 73%% of straw samples contained >50 ng endotoxin/mg, or >1000 IU endotoxin/mg.
Roquefortine C contamination of food and feedstuff is of relevance because of the well-known neurotoxicity of this mycotoxin [ 26].
Weaning stress may be reduced, for example, by exposing the calves to the new environment features they will find after weaning, such as feedstuffs, location of drinking water, new social partners, humans and handling devices.
In vitro rumen fermentation technique has been used for evaluation of nutritional value of feedstuffs, as there is empirical relationship between in vitro gas production and rumen degradation (Makar 2004).
Therefore, the adoption of the laboratory procedures for the quality assessment of feedstuffs aiming at determining the particle size distribution of a new diet for pigs, might be a reliable preventive measure to reduce the risk of gastric lesion onset in the intensive pork production.
These results suggest that a sizeable amount of fish meal can be replaced by plant feedstuffs in diets of turbot when an adequate mixture of plant feedstuffs along with amino acid supplementation are used.
