This study was conducted with the aim of studying the effects of biotin participating in different levels (0, 50, 100 and 150 &micto;g /kg) on nutritional performance and liver fatigue. In the study, 1000 Hybro trademarks were used, and animals were divided into 4 groups, each of which contained 250 Hybro. The trial lasted 49 days. The test ends with the average weights in groups respectively 1841.13; 1871. 78; 1822.88 and 1848.39 g. Accordingly, the highest living weight was achieved in the given group of 50 μg/kg of biotin (P > 0.05). The total consumption of food in groups is 4,295; 4,326; 4,378 and 4, respectively. 294 kg and there was no major variation in food consumption between the groups. During the trial, the sworn effect degrees according to the groups were 2.340; 2.312; 2.405 and 2. It was found at 324 kg. According to this, the animals of the I. trial group consumed less food than the other groups to increase 1 kg of living weight. At the end of the trial, macroscopic studies showed that the liver in the 0 and 50 μg/kg bitoin given groups was smooth and fat, while microscopic studies showed severe fertilization in the liver epithelial cells in the same groups. Hepatic samples of the second (100 μg/kg of biotin) and third (150 μg/kg of biotin) groups were macroscopically normal and no lipid infiltration was confirmed. According to these findings, 50 μg/kg of biotin had a slightly better effect on nutritional performance, compared to other quantities, but was not effective in the prevention of fatty liver syndrome. In this regard, to prevent the appearance of liver fertilization, the broyler race has found that it can be recommended to take part in 100 μg/kg of biotin.
