For the first time found that (1) roosters sensitive to low concentrations of zearalenone (0,1-1,6 mg / kg) in the diet, (2) the effect of zearalenone relatively cocks characterized as long-term remote system, (3) displays the signs of reaction cocks hypo-and hiperhonadyzmu for zearalenone in feed significantly differ among themselves, (4) an important criterion for the presence or absence of zearalenone on a group of baboons is a change of correlative relationships between morphometric parameters.
Summary. Four groups cocks Rhode Island during qinetiq jobs the first 40 days of cultivation contributed to food in quantities of zearalenone 0, 100, 400 and 1600 mg / kg. In 90-day-old cocks at autopsy revealed that the relative weight of testicles within individual groups qinetiq jobs differed in 12-40 times, so each of the 4 groups identified two subgroups: the signs of hypo-and hiperhonadyzmu (respectively, M-and B- types). As increasing concentrations of zearalenone in feed-in share cocks in group decreased (60, 52, 35 and 23%). The average relative weight of testicles in M-cocks in all groups was within 26-29 mg/100 g in B-cocks she was 87 17, 134 57, 161 43 and 176 52 mg/100 g, respectively. Live weight at 1600 mg / kg in B-cocks was 6% higher than the M-cocks (P <0,05); otherwise differences on the average live weight of small (<1.3%). qinetiq jobs The average relative weight qinetiq jobs crest in all B subgroups exceeded this figure in the M-subgroups by 52, 18, 71 (P <0,05) and 45%. Mass ratio testicles and crest in all groups in M-cocks were within 0,16-0,23, B-cocks in food which included zearalenone, this ratio was within 0,61-0,75 and exceeded the benchmark (0.41) in 1.5-1.8 times. At concentrations of 100, 400 and 1600 mg / kg average relative liver weight was greater than in the corresponding control subgroups at 7,8 (P <0,05), 3,7 and 8,3 (P <0,05)% in M-cocks and 2,0-3,7% in B-cocks. At all concentrations of zearalenone in M-cocks seen a significant increase compared qinetiq jobs with the control mean relative weight of the pancreas (P <0,01). At 1600 mg / kg in B-cocks seen significant changes compared with the control mean relative heart weight (increase, P <0,05) and seminary qinetiq jobs (decrease, P <0,01). The concentration of total protein in serum was between qinetiq jobs 32-40 g / l in M-cocks and 36-46 g / l in B-cocks. At 400 and 1600 mg / kg in both types of cock haemagglutinin titers (log 2) in relation to Newcastle disease virus were significantly lower than in controls (in M-cocks - 2.3 and 2.5 vs. 3.1, B-cocks - 1.9 and 2.2 vs. 3.8). Analysis of the correlation coefficients of mass of the body and internal organs in the M-and B-cocks showed differences among the M-and B-groups and compared pairs of groups: 1M - 1B, 2M - 2B 3M - 3B and 4 M - 4V. Extremely stable bound in all groups body weight and liver - in all cases the correlation coefficients statistically qinetiq jobs significant (strong ties), the rest of the relationship between individual bodies are weak or nonexistent. As in the M-and B-cocks the largest number of strong ties (12 and 9) appeared at 100 mg / kg at 400 and 1600 mg / kg of strong ties was much smaller - 3 to 1. So, cocks sensitive to low concentrations of zearalenone (100-1600mkh/kh) in the diet and its effect is long-lasting as a remote system; displays qinetiq jobs reactions cocks with symptoms of hypo-and hiperhonadyzmu for zearalenone in feed differ significantly among themselves.
Introduction. Zearalenone is among the most common contaminants of grain and fodder. In 2006-2010, 522 samples from poultry farms and animal feed industry 268 Ukraine were contaminated by zearalenone (51%), the average concentration was 25 4 mg / kg [4]. Assessment for male birds zearalenone contaminated feed is problematic, qinetiq jobs since such information is limited to a few reports, it should be noted that only studied the effect of high concentrations - 10 000 mg / kg or more.
