IMPACT OF USING SOME BINDING MATERIALS TO REDUCE NEGATIVE EFFECTS OF MYCOTOXINS
IN LACTATING ANIMAL DIETS
Aflatoxin B1; zearalenone; montmorillonite; bentonite; HSCAS; zeolite; sorbent materials, lactating goats, nutrient digestibility, rumen parameters, blood plasma, milk production.
In vitro, Four concentrations of each of four types of sorbent materials; (hydrated sodium calcium aluminosilicates (HSCAS), bentonite, montmorillonite and zeolite) (i.e., 5, I0, 20 and 40 mg/ml) were individually weighted into glass tubes (three replicates per sample) and the amount of aflatoxin B1 (AFB1) (0.5, 10 and 50 ppb) in aqueous solution were separately added. Also, two concentrations of each of two types of clay minerals (bentonite and montmorillonite) (i.e., I0 and 20 mg/ml) were individually weighted into glass tubes (three replicates per sample) and the amount of zearalenone (ZEN) (0.5 and 50 ppm) in aqueous solution were separately added. In vivo, fifteen lactating crossed (Nubian x Baladi) goats of about 2-2.5 years old with an average body weight of about 19-21 kg in the first week of lactation were used in the presented study. The animals were randomly assigned among three experimental treatments (five animals each) using repeated measurement design. The whole feeding period of this trial was 90 days divided into three experimental periods each of 30 days. Each period consisted of 27 days preliminary period followed by a period of 3 days for collection of the experimental samples. Animals were fed three experimental treatments: Control: 60% concentrate feed mixture (CFM) + 40%berseem hay. Bentonite: 60% concentrate feed mixture (CFM) + 40% berseem hay + 2% Bentonite clay as a percentage from concentrates. Montmorillonite: 60% concentrate feed mixture (CFM) + 40% berseem hay + 2% Montmorillonite clay as a percentage from concentrates.
