“…These results agree with previous reports (Vodela et al, 1997;Nolan and Brown, 2000;Sant'Ana et al, 2005;Rahman et al, 2007). However, some studies have reported that low levels of Cd added to diet (3 mg/kg) or water (1.5 mg/l) had a positive effect on performance parameters (Leach et al, 1979;Pribilincova and Marettova, 1996;Toman et al, 2005).…”

The aim of this study was to investigate the effects of different levels of cadmium supplementation (0, 5, 10, 20, 40 and 80 mg/kg) in the diet on performance, egg quality, tibia biomechanical properties and eggshell and bone mineral contents in laying quails. In this 10-week trial, a total of 96 laying quails, aged 21 weeks, were randomly distributed among six experimental groups. Each experimental group contained four replicates of four birds each. The performance parameters were adversely affected quadratically when cadmium was added to the diets in the concentrations of 20 mg/kg and above ( P < 0.01). The specific gravity and eggshell weight were maximal with the addition of 20 mg/kg cadmium to the diet. The biomechanical properties of the tibia were negatively affected by cadmium supplementation in quails ( P < 0.05). The eggshell boron content decreased linearly ( P < 0.001) with cadmium supplementation to the diet. The cadmium content in bone increased when cadmium was added to the diets ( P < 0.001). The bone boron concentration decreased as dietary cadmium supplementation was increased ( P < 0.001).Keywords: cadmium, bone, eggshell, performance, quail Implications Cadmium (Cd) is known as a toxic element for living organisms. However, low levels of Cd added to rations are also reported to have positive effects. In the present study, high levels of added Cd were toxic; however, when added in small amounts, positive effects were observed. There was a negative correlation between Cd and boron concentration in bones. IntroductionNumerous reports have shown that exposure to cadmium (Cd), which is very toxic and non-essential for poultry, results in limitations on growth, increased mortality and decreased egg production (EP) and eggshell quality (Leach et al., 1979;Nolan and Brown, 2000;Sant'Ana et al., 2005;Rahman et al., 2007). Leach et al. (1979) indicated that the addition of Cd (48 mg/kg) to the diets of laying hen markedly decreased EP and eggshell thickness during a 48-week trial period. Similarly, Rahman et al. (2007) showed that exposure to Cd (0.1 to 10 mg/kg BW injection) decreased EP and eggshell thickness in quails.Bones not only provide structural support for birds but are also an important mineral source for metabolic requirements such as for the formation of the eggshell in female birds. Cd has adverse effects on minerals such as calcium (Ca), which is the main component of bones and the eggshell. It has been reported that exposure to Cd decreased bone resistance and mineral levels in bones in rats (Brzoska and MoniuszkoJakoniuk, 2004;.Cd is known to be toxic for humans and animals (Friberg et al., 1992;Jarup, 2002;Satarug et al., 2003;Jemai et al., 2007), but the results of some studies indicate that it may be useful when low levels are added to diets (Leach et al., 1979;Bokori and Fekete, 1995;Pribilincova and Marettova, 1996;Rahman et al., 2007). Leach et al. (1979) reported a positive effect of Cd supplementation (3 mg/kg) on EP during a 12-week study in laying hens. Pribilincova and Mar...

“…In nature, this level of egg contamination of wild (Tsipoura et al, 2011) and domestic birds (Sato et al, 1997;Lucia et al, 2010;Kim and Oh, 2014) is usually not exceeded because the transfer of toxic metal ions from the environment into eggs is strongly limited by a highly specific barrier between the oviduct and the egg (Sato et al, 1997;Rahman et al, 2007). On the other hand, a low but permanent cadmium content (1.3 ppm) of drinking water and/or food can significantly decrease egg production and weight as well as hatchability in hens (Vodela et al, 1997), pheasants (Toman et al, 2005), and ducks (Lucia et al, 2010). However, in contaminated areas the amount of cadmium in chicken eggs may exceed 4.0 µg/egg (71 µg Cd per kg of egg) as compared with the average level, which is about 0.1-0.8 µg/egg (Dobrzański et al, 2004).…”

The aim of this study was to determine the effect of cadmium on Muscovy ducklings (Cairina moschata) based on hatching results and the activity of enzymes in the blood plasma. On day 6 of incubation, hatching eggs were injected into the egg albumen with 50 µl of saline solution containing Cd ions (CdCl 2 ) at concentrations of 0 (control group), 1.3, 4.0, 7.5, 15.0 and 30 µg/egg, using 50 eggs per group. A gradual decrease in hatchability, from 52% in the control to 4% in the highest Cd dose group, was observed, with the LD 50 calculated as 8 μg/egg. However, the impact of cadmium on the incidence of malformations of duck embryos has not been proven. Compared to the control group, N-acetyl-β-Dglucosaminidase activity increased by 30-50% (P ≤ 0.05) in the blood serum of ducklings in the groups receiving more than 7.5 µg Cd/egg, whereas an elevated activity of arylsulphatase (by 45%) was observed for a lower dose only (4 µg Cd/egg). A gradual increase in the activity of alanine and aspartate aminotransferases was observed (P ≤ 0.05), starting from the lowest exposure of 1.3 µg Cd/egg, by 155% and 53%, respectively. In conclusion, the results prove the dosedependent toxic impact of cadmium on embryogenesis and on the studied blood plasma enzyme activities of ducklings.

Arsenic poisoning is now considered as one of the biggest environmental disaster and a major public health issue. Incidence of arsenicpoisoning has been reported from many parts of the world. While Bangladesh and West Bengal (India) account for the most of the incidence, occasional reports from Mexico, Taiwan and mainland China have also appeared.It is a natural metalloid found in low concentrations in virtually every part of the environment as it is used in a wide variety of industrial applications, from computers to fireworks. Ground water arsenic is the major source of poisoning in animals and human. About 80% of ingested arsenic is absorbed and metabolized in liver and then excreted through urine and faeces while upon chronic exposure, it is deposited in liver, kidney and skin. Human populations are also being exposed to this poison by consuming the milk of affected animal.Inorganic forms of arsenic are more toxic compared to organic forms. Acute toxicity is rare in nature in comparison to chronic toxicity, which is prevalent in contaminated areas. Most non-ruminants are more susceptible to intoxication than ruminants. Chronic exposure of arsenic in animals and human beings causes severe adverse effects in the form of lowered immunity, diseases and production performances.
