“…The highest average Fe content was noted in milk from Rzaska, the values were lower for milk from Zabrze and Ś lemień. The physiological Fe content in goat's milk ranges from 0.1 -0.7 mg/l [22]. The results obtained during our examinations exceeded the range values in the majority of cases but were pretty close to values stated by other authors [23].…”

“…The values obtained during the examinations did not exceed the physiological Cu content in goat's milk which ranges from 0.2 -0.6 mg/l [22]. The research showed that the content of copper in goat milk does not exceed the top limit of natural presence and this has positive influence on the taste of milk.…”

“…The highest average value was reached by milk from Ś lemień while the lowest one by milk from Rzaska. The physiological manganese content in goat's milk, according to Haenlein [22] ranges from 0.07 -0.09 mg/l. The attained Mn content, higher than its natural content in goat's milk, points to the fact that the environment from which the tested goat's milk came is contaminated with this element.…”

The aim of the work was to estimate the content of certain metals in goat's milk. The content of lead, cadmium, iron, copper, zinc, manganese and magnesium was determined using atomic absorption spectrometry. It was found that highly toxic elements [Pb, Cd] appeared in both raw and pasteurised goat's milk in amounts not exceeding the polish standard. Goat's milk coming from highly industrialised regions demonstrated higher lead content than milk from agricultural regions. The copper and zinc contents in examined raw and pasteurised goat's milk were well under the polish standard.

“…Zn is used as a co-factor in several enzyme systems (Virgil and Melvin 1970) and necessary for growth and development, its deficiency may result growth retardation by reduced enzymatic activity, altered testicles, excessive salivation and anorexia (Haenlein 1980). Zinc concentration in the milk varied from 0.6 to 8.4 mg L Whereas, 2.13 mg L −1 zinc content in the milk of Croatian goats has been reported by Slačanac et al (2011).…”

Quantification of minerals and trace elements in raw caprine milk using flame atomic absorption spectrophotometry and flame photometry

et al. 2014

This study reports minerals and trace elements quantification in raw caprine milk of Beetal breed, reared in Northern India and their feed, fodder & water using flame atomic absorption spectrophotometry and flame photometry. The mineral and trace elements' concentration in the milk was in the order: K > Ca > Na > Fe > Zn > Cu. The results showed that minerals concentration in caprine milk was lesser than reference values. But trace elements concentration (Fe and Zn) was higher than reference values. Multivariate statistical techniques, viz., Pearsons' correlation, Cluster analysis (CA) and Principal component analysis (PCA) were applied to analyze the interdependences within studied variables in caprine milk. Significantly positive correlations were observed between FeZn, Zn -K, Ca -Na and Ca -pH. The results of correlation matrix were further supported by Cluster analysis and Principal component analysis as primary cluster pairs were found for Ca -pH, Ca -Na and Fe -Zn in the raw milk. No correlation was found between mineral & trace elements content of the milk and feed.

“…Alopecia, wool eating, general malaise, depression, crusting fissured skin, skin covered with crusted scales, stiff gait and arching of the back were documented in small ruminants in field cases. Several cases of experimentally produced zinc deficiency in goats have been described 4,5,19,20 . Zinc‐deficient diets fed to ram lambs and sexually mature male goats caused impaired testicular growth, no libido and complete cessation of spermatogenesis 19,20 .…”

Two cases of zinc deficiency in dairy goats from different flocks and not associated with a zinc-deficient diet are described. Hard, dry, hyperkeratotic skin, hair loss and pruritus especially prominent on the back, legs, udder, face and ears were the most common clinical signs. Skin biopsy findings revealed a mixture of orthokeratotic and parakeratotic hyperkeratosis. On initial examination, serum zinc concentrations were low in both goats (461 microg L(-1) and 521 microg L(-1), respectively). Although mild skin lesions persisted during the early stages of zinc supplementation, skin lesions completely resolved after prolonged oral zinc supplementation. Withdrawal of zinc supplementation resulted in re-appearance of lesions in both animals. Case 2 gave birth to two kids, one of which showed mild skin lesions at 8 months of age together with a low serum zinc concentration (434 microg L(-1)), suggestive of hereditary zinc malabsorption. The other kid remained free of skin lesions and had a serum zinc concentration (530 microg L(-1)) within the normal range. On the basis of historical and clinical findings, the cases presented here more closely resemble Syndrome 1 hereditary zinc deficiency as seen in Nordic dog breeds rather than other zinc deficiency conditions seen in other species. It is suggested that zinc deficiency in these goats was due to hereditary malabsorption of dietary zinc. This is the first descriptive study of this condition in goats. Life-long zinc supplementation may be necessary in such patients.
