Lead (Pb) is an environmental pollutant, especially due to its
anthropogenic activity.The present study aimed to investigate some
of the toxic effects of lead exposure in quails and its
amelioration through vitamin E supplementation. A total number of
420, day old chicks of Japanese quail were assigned seven dietary
treatments.. Control group received only basal diet without any
supplementation. Other groups received lead (Pb) alone or in
different combinations with vitamin E. Lead (Pb) was administered
in the feed at a dose level of 50, 75 and 100 mg/kg Pb. Vitamin E
was administered in the feed at a dose level of 40mg/kg vit E .The
body weight of each bird was weighed weekly and found significant
changes in the weight of quails. Pathological lesions in lead (Pb)
fed birds included enlarged, pale, friable liver and swollen
kidneys.On the other hand, supplementation of vitamins E in lead
intoxicated birds showed ameliorative effects in Lead (pb)
toxicity. It was concluded that the vitamin E ameliorated the lead
induced toxic effects in some of parameters studied
This study was carried out on 90 one-day-old broiler chicks to know
clinico-hematological alterations, DNA damage caused by
cypermethrin (CY), and attenuation of toxic effects by vitamin E
(Vit E) and selenium (Se). Birds were randomly divided into five
equal groups.Birds were monitored twice daily for clinical signs.
They were weighed and blood samples were collected for
hematological studies. CY-treated birds showed more prominent signs
of toxicity compared to CY+Vit E, CY+Se and CY+Vit E+Se birds. Body
weight in groups 1-3 was significantly (P>0.05) smaller at days
20 and 30 when compared with the control group. Significantly
(P>0.001) higher numbers of micronuclei appeared in chicks
treated with CY compared to CY+Vit E- and CY+Se-treated birds.
Significantly decreased total erythrocyte counts (TEC), hemoglobin
(Hb) concentration and packed cell volume (PCV) in all treated
groups were recorded.It can be concluded that CY induces toxic
effects in broilers chicks; however, these toxic effects can be
ameliorated by Vit E or Se. Combination of Vit E and Se was more
effective to ameliorate toxic effects of cypermethrin.
Mycotoxins can affect human health directly or indirectly (food
chain). The mycotoxin causes human illness by acting as
immunosuppressive and carcinogenic agent when ingested with
different food items. Mycoses are the best-known diseases of fungal
etiology and its toxic secondary metabolites also cause important
health hazards. Thus, it concludes that mycotoxins pose an
important risk factor to human as well as animal health. This study
will help in better understandings about effects of mycotoxins on
birds' health. The present study was designed to investigate
pathological and immunosuppressive effects of aflatoxinB1 (AFB1)
and Ochratoxin A (OTA) in broiler chicks. Study was conducted on
270 broiler chicks. After exposure of mycotoxin, kidney and liver
showed significant increase in weight. Serum alanine
aminotransferase and total serum proteins were significantly
increased and decreased, respectively. Serum urea and creatinine
were significantly increased after exposure. This all increased
their susceptibility to infections. This study suggested that AFB1
& OTA show synergistic effects in developing different
pathological changes in the body of chicks.
This study was done to explore the toxic effects of Aflatoxin B1
alone and in combination with Ochratoxin A in quail chicks. Day old
quail chicks divided into seven equal groups (G0-G6) were
administered with aflatoxin (AFB1) and ochratoxin (OTA) alone or in
different combinations in feed. Ochratoxin was administered at dose
levels of 1 and 1.5 ppm alone and 2ppm OTA in combination with 1
ppm AFB1 in G1, G2 and G3 respectively. AFB1 was administered daily
into feed at dose rates of 1 and 1.5 ppm alone and 2ppm AFB1 in
combination with 1 ppm OTA in G4, G5 and G6 respectively. Quail
chicks fed ochratoxin had decreased feed intake and body weight.
Quail chicks administered AFB1 alone showed depression, decrease in
feed intake and body weight. Hematological parameters exhibit a
decreasing pattern including TEC, TLC, Hb, PCV and ESR. Serum urea
and creatinine concentrations increased while total serum proteins
decreased. A concurrent administration of AFB1 with ochratoxin
indicated a potentiation of the toxicity reflected by increased
severity of clinical signs, mortality of the chicks and decreased
body weights. Other parameters studied did not show significant
differences.
