Abstract: This double-blind, placebo-controlled clinical study evaluated the effects of iron supplementation on cognitive function in adolescent girls with non-anaemic iron deficiency. Methods Seven hundred and sixteen girls enrolled in four Baltimore high schools were evaluated for nonanemic iron deficiency (serum ferritin <12 µg/L with normal hemoglobin). Ninety-eight (13.7%) girls were non-anemic iron deficient, of whom 81 subjects were randomized to receive oral iron sulfate (650 mg twice daily) or placebo for 8 weeks. The effect of iron treatment was assessed using questionnaires, hematological and cognitive tests administered before the start of treatment and repeated after the procedure. Results Of the 81 non-anemic iron-deficient girls, 78 (96%) completed the study (39 in each group). Five girls (three control, two treatment girls) developed anemia during the intervention and were excluded from the analyses. Ethnic distribution, mean age, serum ferritin concentrations, hemoglobin concentrations and cognitive test results of the groups did not differ significantly at baseline. The hematological measurements of the iron status after the intervention improved significantly in the treatment group (serum ferritin 27.3 vs. Regression analysis showed that girls who received iron performed better than girls in the control group on a test of verbal learning and memory (p<0.02).Interpretation In this urban population of nonanemic iron-deficient adolescent girls, iron supplementation improved verbal learning and memory.

Abstract: As an environmental stressor due to global warming, heat stress (HS) is considered as a major challenge in poultry industries in tropical countries like Bangladesh for substantial economic loss because of its severe effects on poultry health and productivity. Dietary betaine is thought to be an effective solution for reducing such losses. An experiment was conducted on 250 Ross 308 broilers for 35 days to see if betaine supplementation could improve performance under stressful conditions. During the trial, broiler birds were exposed to artificial HS of 30°C for 8 hours (in 18,19 and 20 days) and for 11h (in 26,27,28 days) during the day. The treatments are, G1: control feed without HS; G2: control feed with HS; G3: control +HS+1 g/kg betaine; G4: control + HS +1.5 g/kg betaine and G5: control +HS+2 g/kg betaine from day 11 to day 33 and average weight (AW), daily weight gain (DWG), feed intake (FI), FCR were analysed. HS had a lower effect on average weight and daily weight gain for the chickens whereas in total FI and FCR, betaine treated feed have some significant effect (p<0.05) for FI and (p<0.05) and FCR. Overall, supplementation of the betaine did not show any adverse effect on the zootechnical performances of experimental species and seems to support the birds during stressful condition.
