“…Miller et al (1990) have shown that the level of Pb in blood has a significant correlation with the levels and/or metabolism of essential trace metals. The results of the study conducted by Nwude et al (2010) in Awka Southern Nigeria on the blood Pb of cows shows a mean concentration (mg/kg) of 2.79, a value lower than obtained from this study. Blood Pb levels in lactating cows have been shown to be transfer into milk.…”

“…His results show that increase in the levels of Cd and Pb on plants correlates with an increase on the levels of these heavy metals on soil, he concluded that the most likely sources of Cd and Pb in the soils and plants were pesticides and phosphorus fertilizer. The 0.004 mg/kg minimum blood Cd value detected in our study tally with the value obtained by Nwude et al (2010) when they sampled the blood of cows in Awka, Southern Nigeria. However, they obtained 0.02mg/kg as maximum blood Cd concentration, a value that is four times lower than the 0.093mg/kg obtained in this study.…”

“…The mean blood Fe detected in this study is above the recommended levels for tissues. It is also above the aggregate value of 1.21mg/kg detected in the blood of cows by Nwude et al (2010) in Southern Nigeria and ten times higher than the mean blood Fe levels of 4.346mg/kg reported by Tomza-Marciniak et al (2011) from an inorganic and intensively managed Holstein-Friesian cows in Poland. The high levels of Fe recorded in this study may likely be from the irrigation water or from bore hall water which the study of Coup & Campbell (1964) shows that water sources from borehole contain high levels of Fe and can contaminate Pasture and crops when used for irrigation.…”

The study was carried out to determine the presence and concentration of some heavy metals in the blood of Holstein-Friesian cattle in a private farm in Nasarawa State Nigeria. Blood samples were obtained from 22 Holstein-Friesian cattle consisting of 21 cows and 1 bull, of ages between 3.5 and >3.5 years. The samples were analyzed using Atomic Absorption Spectrophotometer (AAS). The mean lead (Pb), Iron (Fe) and Cadmium (Cd) concentrations were 1.160, 47.681 and 0.051 mg/kg, respectively. There was no significant (P>0.05) effect of age and sex on the concentration of Pb, Fe and Cd. The study found the presence of Pb, Fe and Cd in blood samples collected from Friesian cattle. The FAO/WHO permissible limit of Cd and Pb in blood is 0.5mg/kg. Pb was detected above the maximum limit. The high concentration of these metals recorded could be as a result of prolong use of inorganic agricultural products and likely irrigation water which contaminate the feed. High levels of these metals in Holstein-Friesian can cause decreased milk production, placenta damage, mineral deficiency and respiratory failure among others. Inorganic agriculture should be replaced with organic methods; industrial activities close to pasture yards should be avoided. Sources of irrigation water should be free from heavy metals contamination.

“…Heavy metals are not biodegradable, they tend to accumulate and magnify their effect in the different stages of the production chain, so their presence in animals can affect their health by accumulating in internal organs casing hematobiochemical and pathological alterations in these organs (Nwude et al, 2010;Gashua et al, 2018;Kar and Patra, 2021) existing Bioaccumulation and Toxicopathological damage and finally have a negative impact on food security (Lokeshwari and Chandrappa, 2006;Tchounwou et al, 2012;Castro et al, 2013).…”

The aim of this work was to determine the content of lead (Pb), chromium (Cr), cadmium (Cd), arsenic (As), copper (Cu), strontium (Sr) and thallio (Tl) in blood, milk and urine from cows fed forage irrigated with sewage water and cultivated in the vicinity of the Popocat epetl volcano and determine the rate of transfer of these elements from blood to milk and urine. Digestion was performed in a microwave oven (CEM-MarsX). The determination was made using an ICP -OES. The Cd in the blood was significantly higher than in milk and urine. The Cr in the blood was higher than in the urine. In milk the content of Pb and Cu was significantly higher than in blood. Sr and Tl concentration in the urine was higher than that detected in milk and blood and Pb in blood. Milk transfer Index revealed a significant difference in relation to the TI values found in the urine and only in the case of Cu in milk was TI > 1. In urine, the values found of Sr and Tl were higher than milk TI. It is concluded that when metals are ingested by cows in fodder, they are easily transferred to milk and urine through the blood. Presence of heavy metals in the different matrices determines the degree of environmental and trofic chain contamination with which we can consider the cow a biomarker.

“…First of all, the glass wares used in the experiment were washed with distilled water, followed by rinsing with deionized water and nitric acid and then allowed to dry. The method of Nwude et al (2010) was utilised with modification of procedures of digestion as follows: ten (10) gram of each blood sample was introduced into a 50 mm conical flask.…”
