A STUDY ON NUTRITIONAL STATUS OF TRACE MINERALS OF CATTLE IN JAVA IN INDONESIA
Kumagai, H.,Ishida, N.,Katsumata, M.,Yano, H.,Kawashima, R.,Jachja, J. Asian Australasian Association of Animal Productio 1990 Animal Bioscience Vol.3 No.1
The nutritional status of trace minerals in cattle of Java in Indonesia was investigated by evaluating Cu, Fe, Mo, Zn and Mn concentrations in diets and livers, and Cu and Zn concentrations in blood plasma. Investigations were conducted on Jonggol (West Java), Malang (East Java) and Mojokerto (East Java) in both the rainy and the dry seasons in 1988. In Jonggol, low Cu concentrations in diets showing 7.1 mg/kg in the rainy season and 10.9 mg/kg in the dry season were observed and all plasma samples showed Cu concentrations below the critical level ($0.65{\mu}g/ml$). Thirty percent of the liver samples in Malang and 54% of those in Mojokerto showed lower Cu concentrations than the critical level (75 mg/kg on a dry matter basis). Fe concentrations in diets from the three regions showed a wide variation of values ranging from 249 to 30,000 mg/kg. A large amount of Fe was accumulated in livers from Malang and Mojokerto, giving average concentrations of 498 mg/kg. Zn concentration in diet and plasma samples were close to the borderline and some Zn concentration in these samples showed deficient levels. Mo and Mn concentrations in diets and livers showed normal levels.
A STUDY ON NUTRITIONAL STATUS OF MACRO MINERALS OF CATTLE IN JAVA IN INDONESIA
Kumagai, H.,Ishida, N.,Katsumata, H.,Yano, H.,Kawashima, R.,Jachja, J. Asian Australasian Association of Animal Productio 1990 Animal Bioscience Vol.3 No.1
Nutritional status of cattle in Java in Indonesia was investigated by evaluating P, Ca, Mg, K and Na concentrations in forage and plasma inorganic phosphorus (Pi), Ca and Mg, hematocrit and hemoglobin concentrations of cattle during both rainy and dry seasons in 1988. Investigations were conducted at Jonggol (West Java), Malang (East Java) and Majokerto (East Java). Low P content in forage averaging 0.11% on a dry matter basis, high Ca:P ratio in forage in the rainy season (7.7:1) and low plasma Pi concentrations averaging 4.71 mg/dl were observed in Jonggol. In all three places, Ca content in forages was higher than the requirement according to the NRC standard and plasma Ca concentrations were above the critical level. During the rainy season forty percent of cattle in Malang and Mahokerto showed plasma Mg concentrations below 2mg/dl in spite of normal Mg and K content in forage. Forage samples from each place showed a wide variety in Na content, and Na content of two thirds of forage samples was lower than the requirement according to the NRC standard. Hematocrit and hemoglobin concentrations in Malang and Majokerto showed higher values than the normal range.
