Chronic intoxication with Aflatoxins can manifest with decreased weight gain, reduced feed conversion and, sometimes, diarrhea.
Fumonisins, in the most severe cases of intoxication, can cause symptoms such as diarrhea, decreased food intake, and decreased body weight gain.
Toxin T-2 can cause a reduction or refusal of food intake, as well as digestive disorders such as ulceration and visceral bleeding.
In order to create a differentiated product, PATENT CO has identified the strengths of mycotoxins, allowing us to attack their weaknesses.
MINAZEL PLUS has 4 factors that make it different:
- 1. EFFICACY: ability to adsorb polar and less-polar mycotoxins
- 2. SELECTIVITY: it does not adsorb feed nutrients such as vitamins, amino acids and minerals.
- 3. SPEED OF ADSORPTION: knowing that mycotoxins begin to be absorbed by the body 30 min after ingestion, the adsorbent must be able to have adsorbed as many mycotoxins as possible before that time.
- 4. DESORPTION: throughout the digestive tract, the adsorbent + mycotoxin complex passes through different pH. If the adsorbent is not stable in these pH changes, it will “release” the mycotoxin, causing desorption and allowing the mycotoxin to become available again to be absorbed by the body.
OBJECTIVES OF THE EXPERIMENT
The present experiment aims to demonstrate the zootechnical and economical effects on the control of mycotoxins in broiler chickens by comparing two mycotoxin adsorbents, MINAZEL PLUS and a usual company adsorbent.
The experiment was conducted in a poultry farm in São Paulo State, Brazil.
This experiment consisted of two trials (5 houses each), the first trial (Houses 1-5) was carried out in July 2019 and the second trial (Houses 6-10) in August 2019 as shown below:
- ⇰ In this trial, 3 houses (H3-5) received the feed mixed with MINAZEL PLUS at a dosage of 1 kg/ton in the pre-starter and starter feed (until 21 days).
- ⇰ The other 2 houses (H1-2) received the feed mixed with a commercially available mycotoxin adsorbent, at a dosage of 0.5 kg/ton in the pre-starter and Starter feed (1 to 21 days).
Each house had 23,000 birds; so, 69,000 birds received the feed with MINAZEL PLUS, whereas 46,000 birds received the feed with competitor binder.
For this part of the trial (houses 1 to 5) mycotoxin analysis of pre-starter and starter feed was performed.
In the houses from 6 to 10, 23,500 birds/ house were reared, so 70,500 birds received MINAZEL PLUS (house 8-10) and 47,000 (house 6-7) received competitor’s product.
For the second trial (houses 6 to 10) mycotoxin analysis from pre-starter feed was performed.
Necropsy was performed in both trials before 21 days old.
- Concentration of mycotoxins in feed: Aflatoxin, Fumonisin and T-2 Toxin
- Weight of the broilers at 21 days (end of starter feed)
- Final Weight of the broilers
- Mortality at 21 days
- Mortality at the slaughterhouse
- Necropsy: liver quality, body petechiae, mucosal necrosis and gizzard

The use of MINAZEL PLUS in the diet favored a better weight gain at 21 days (3.85% compared to standard weight) and at 42 days (8.51% as compared to standard weight). Also, it resulted in lowest mortality at 21 and 42 days.
The house 8 that was fed with MINAZEL PLUS, had the highest weight gain at 21 days (-5.35% of standard weight) and at 42 days also got the highest weight gain (-3.64% of standard weight).
The lowest mortality at 21 days was recorded from house 9 (1.39%) which received MINAZEL PLUS in feed.
Necropsies were performed in houses 1 to 5 when the birds were 17 days old and in houses 6 to 10 when birds were 20 days old. No significant lesions were observed in any of the groups.
