Review Current

Iron deficiency is presently a serious problem in suckling piglets on pig farms. The most often used method of anaemia prevention in piglets is parenteral administration of iron dextran. Oral iron represents an alternative to this method. The goal of this article is to review current knowledge on oral iron administration in suckling piglets. The substances that can be used for this purpose include iron dextran, iron salts, iron chelates, carbonyl iron, an iron polymaltose complex and iron microparticles. The different methods of oral iron administration in piglets are discussed.

Iron Chelate

The present study was aimed to investigate the using iron chelates viz., ferrous glycinate and ferrous citrate for the remediation of iron deficiency in alkaline and calcareous soil. The lab experiment was carried out to study the synthesis of Fe chelates by using organic and amino acid based chelating agents. The Fe chelates were synthesized based on 2:1 molar ratio of chelating agents and metal ions. The synthesized iron chelate was characterized by using Fourier transform infrared spectrophotometer (FT-IR). Finally, the synthesized amino acid and organic acid chelated iron were used to remediate the calcareous soil with black gram as a test crop. Iron content in black gram (above ground mass) tented to fluctuate at different growth stages. The highest shoot iron content of 325, 351 and 347 mg kg-1 at vegetative, flowering and harvest stages were recorded with 1% ferrous glycinate as foliar spraying on 25 and 45 Day after sowing (DAS). The root iron content was also higher in 1% ferrous glycinate as foliar spraying on 25 and 45 DAS. The current investigation affirmed that the utilizing different chelating agents like the ferrous glycinate were powerful than ferrous sulfate, which may build the iron substance and iron take-up of blackgram in various development stages.

Yellow Color

The strawberry is a low-growing, herbaceous perennial plant, sensitive to iron deficiency. The iron deficiency represents a nutritional disorder, leading to a decreased content of photosynthetic pigments, which determines the yellow color characteristic of chlorotic leaves. Therefore, in calcareous soils, the use of synthetic iron chelate is often mandatory in strawberry cultivation. The employment of novel microorganism-based formulations as alternatives to the use of iron chelates, was evaluated during strawberry cultivation by monitoring the morpho-biometric parameters, chlorophylls, the iron content in leaves and roots, and the Fe chelate reductase activity involved in absorption of iron during the chlorosis event in plants using the strategy I. The experimental design envisaged growing strawberry seedlings on an inert substrate (pumice), irrigated with Hoagland solution iron-free, with a 12 h photoperiod. After 42 days, at the first appearance of chlorosis symptoms, plants were transplanted into a calcareous soil, and after seven days, they were treated, by a single application, with a microorganism-based formulations (MBF), an inoculum (In) of Trichoderma spp. and Streptomyces spp., or Sequestrene (Sq). Strawberry plants were sampled and analyzed at 5, 10, 15, and 20 days from the treatments. The results showed that microorganism-based formulations positively affected the strawberry seedlings, by reducing the chlorosis symptoms, producing comparable effects to the Sequestrene treatment.

SUMMARYSoil analysis on samples taken from apple orchards in Khorasan and quince orchards in Esfahan, suggested that at a sampling depth of 20–45 cm., the critical soil concentration of calcium carbonate at which chlorosis might appear seems to be 14–15 per cent for apple and 39–40 per cent for quince. The incidence of lime-induced chlorosis was accompanied by lowered leaf Ca/K ratios. The application of various iron chelates to chlorotic trees not only benefited yield of apples but also exercised a residual effect in succeeding seasons.
