| Popis: | In order to mitigate the negative effect of mycotoxins the major researches have been conducted to obtain the mycotoxins adsorbent in recent years. As for the adsorbents, they are substances of a firm or liquid form, on which surface the mycotoxins are absorbed and prevent transition of mycotoxins from the intestines walls in to blood system. The bentonite clay obtained in western region of Georgia (Guria, Ozurgeti) is characterized with a broad range of ion exchange, high colloidal, enriched, for its wide adsorption characteristics and exchange capacity It is widely used in oil exploration, filtration of wine, vinegar, oil, production of pharmaceuticals, perfumery, cellulose, it is used in agriculture. Based on the mentioned characteristic of locally produced bentonite clay, for the purpose of mycotoxins adsorption in ready combined food the various portions (1.0%, 1.5%, 2.0%) of Askangel has been tested on Broiler “Cross-308”. Based on preliminary (10-10 bird in each group) and primery (50-50 birds in each group) experiment the impact of the “Askangel” on broiler productivity and its adsorbtion capacity has been identified. The dynamic of the live mass showed that at the start point of the experiment (20 day) in first, second and third (3,4,5) groups the live mass (Tables 2 and 4) was nearly equal 0.8–0.83 kg, at the end of the experiment the advantage of the third, fourth and fifth groups was (the combined food was balanced with Askangel 1%, 1.5%, 2.0%) compared with the first and second groups. The indicator of the third group was ahead by 5,1%, the fourth group by 7.1% and the fifth by 8.2%, accordingly to second control group by 2,7%, 4.7% and 5.8%. In each group we observed poultry feeding, feed utilization and conversion. According to the obtained data the feed conversion in the third testing group compared to the first control group was less by 3%, in the fourth group by 5%, in fifth testing group by 3,7%. Compared to the second group the indicator is as follows: 1,2%, 3,1% and 1,85%. During the experiment, for the physiological tests the samples of manure was taken from all five groups and the mycotoxins adsorption ability of betonies clay “Askangel” was identified at the LTD “Chirina” laboratory “SANA” using ELIZA method. The highest capacity of adsorption was seen in fifth group, in the mentioned group the Askangel was added with the portion 1.5–2% where the adsorption rate of aflatoxin was 79%, T 2 HT 2 adsorbtion 8.3%. During the testing period the broiler daily weight gain in third group was 72.8 gr, in fourth 77.5 gr. The less daily weight gain was observed in first and second control groups: 68.2 gr and 69.6 gr. |
