ЕФЕКТИВНІСТЬ ЗНЕЗАРАЖЕННЯ КОРМІВ ТА ВИРОЩУВАННЯ КУРЧАТ ЗА ВИКОРИСТАННЯ В ГОДІВЛІ ЛІГНОСОРБЕНТУ

Abstract

За результатами проведеного токсикологічного аналізу встановлено, що дослідний комбікорм був слаботоксичним і в ньому виявлено Т-2 токсин і афлатоксин В1. Використання 0,5 % Лігносорбенту у складі повнораціонного комбікорму з вмістом 15 % слаботоксичного корму та без нього сприяло підвищенню ефективності вирощування курчат та покращувало їх гематологічні показники.

На основании токсикологического анализа установлено, что опытной комбикорм был слаботоксичным и в нем были выделены Т-2 токсин и афлатоксин В1. Использование 0,5 % Лигносорбенту в комбикорме ПК 2-1 с содержанием 15 % слаботоксического корма и без него способствует улучшению эффективности выращивания цыплят и их гематологические показатели.

The scientific survey objective was to study the effectiveness of Lignosorbent application for disinfecting mixed fodders affected by mycotoxins, and its effect on blood values and chickens productive qualities. Experimental studies were carried out for 30 days on 4-week-old chickens of Adler Silver meat egg chickens under conditions of the vivarium of the Odessa Research Station National Research Center «Institute of Experimental and Clinical Veterinary Medicine» (ORS NRC «IECVM»). By the principle of analogues pairs, the chickens were divided into 4 groups of 25 heads each. Group 1 chickens (positive control) received complete mixed fodder PK 2-1, to which 0,5 % of Lignosorbent was added for chickens of the 3rd group. Chickens of the 2nd group (negative control) were fed with mixed fodders PK 2-1 with inclusion of 15 % of low toxic mixed fodder (mixed fodder under study). 4th group chicken were fed with mixed fodder PK 2-1 with a 15 % content of a low toxic feed and 0,5 % of Lignosorbent added. Based on results of the toxicological analysis, by using the Colpoda steinii infusoria as a test object, it was established that the experimental mixed fodder was low toxic (an aqueous extract оf the mixed fodder study resulted in death of the colpods after 35 minutes after application). At the same time, T-2 toxin in the amount of 0,3 mg/kg (1,5 MVD) and aflatoxin B1 – 0,05 mg/kg (2 MVD) were found in the mixed fodders. Inclusion of 15 % low toxic fodder (the second group) in the composition of the complete mixed fodder, compared with the chickens of the first group, has reduced the live weight of the chickens by 10,20 % at the end of cultivation, the average daily gain by 33,01 %, daily feed intake by 5,48 % and payment for feed by a 25,68 % increase in live weight, as well as increased the discharge by 9,45 % and its humidity by 11,08 %. As for the blond serum of the second group of chickens, a decrease in the content of total protein by 12,87 %, γ-globulin by 8,51 %, CIC by 37,50 % and seromucoids by 23,07 % was observed. At the same time, an increase in uric acid by 17,20 % has been stated. Pathological changes in the body of the second group chickens were accompanied by an 0,56 % increase in the liver weight relative to body weight and a 0,26 % decrease in the weight of the spleen relative to body weight, compared to the chickens of the first group. Application of 0,5 % Lignosorbent in feeding within the mixed fodder PK 2-1, with 15 % of low toxic feed and without it, prevented of pathological changes in the body, promoted the increase in the efficiency of chickens breeding and improved their hematological values, which indicates its ability to inactivate the negative effect of toxic fodders, to improve immunity, to assimilate nutrients, to preserve stock and the growth rate of chickens.
