The difference among studies may be explained, at least partially, by the timing of supplementation and the main outcome measured.
Following these studies, the government prioritized anaemia control in the 9th Five Year Plan and developed a multi-pronged national strategy with introduction of a weekly Iron Folic Acid supplementation (WIFS) as the main intervention.
Natural nutrient materials are not a sufficient source of vitamin D to supply the body requirements; therefore where there is no supplementation of foodstuffs, the main source for vitamin D is produced by UV light [ 4, 5].
Preliminary data have suggested that nutritional intervention with fish oil supplementation, which is the main source of n-3 LCPUFA, in cancer patients may lead to weight gain, maintenance of lean body mass, improved performance status and increased appetite in ambulatory H&N cancer patients when administered peri- or postoperatively [ 13– 15].
A 12-week feeding trial was conducted using a factorial treatment design with taurine supplementation (3 levels) and methionine supplementation (3 levels) as the main effects.
The results of this study may be important for the design of a larger intervention trial with calcium supplementation with fracture as the main outcome.
Data were analyzed as a completely randomized design; stocking rate and supplementation treatment combinations were the main effects, pasture was the experimental unit, and year was a random effect.
The study participants were randomly allocated to either supplementation or placebo in the main trial.
Thus, the partial replacement of crude protein of soybean meal by sunflower meal in diets for hens is economically feasible, provided that the amino acid profile is corrected through supplementation, allowing the maintenance of the main quantitative and qualitative indices.
Regarding fetal weight, this parameter was not affected by maternal cholic acid supplementation [ 54], suggesting that the main effect on fetal growth in our study is not due to cholic acid itself.
