Effects of organic zinc supplementation in weaned calves

Effects of probiotic dietary supplementation on diarrhoea patterns, faecal microbiota and performance of early weaned calves

Twenty Lithuanian Black-and-White calves (10 bulls, 10 heifers) were used to evaluate the effects of the supplemental probiotic product, Enterococcus faecium M74 (2.4 g/day/calve), added to fresh milk and skimmed milk in a 56 day-study. The probiotic was administered by dietary supplementation to first group of calves and their respective pens (probiotic group), whereas the second group (contro...

Effects of oral iron supplementation on haematocrit, live weight gain and health in neonatal dairy calves

Forty neonate calves were used in this study. The animals were divided into two treatment (n = 20) andcontrol (n = 20) groups. In the treatment group, oral iron as ferrous sulphate was supplemented to each calf atthe dose of 150 mg/day for 28 days, from the birthday.

Plant value of zinc in organic wastes

Zinc repletion with organic or inorganic forms of zinc and protein turnover in marginally zinc-deficient calves.

We conducted two experiments using marginally Zn-deficient (-Zn) calves to determine which supplemental chemical form of Zn would most rapidly reverse certain Zn deficiency signs and to determine whether a change in protein turnover had occurred in Zn deficiency. In Exp. 1, 40 crossbred beef heifers were allocated by BW to four groups. The control group received 23 mg Zn/kg diet DM from ZnSO4 s...

Effects of zinc supplementation on child mortality.

Malnutrition, including micronutrient defi ciencies, is the leading risk factor for child mortality in low-income and middle-income countries. About 30% of the world’s population has zinc defi ciency (fi gure). This defi ciency occurs because zinc is mainly contained in foods such as red meat that are expensive and in short supply in developing countries. Moreover, zinc has no tissue reserves, ...
