1. Male broilers (0 to 35 d) were given foods with two types of yellow sorghum substituted for maize in isonutrient diets. Sorghum-based foods were also supplemented with extra phosphorus, to provide a total P of about 8 g/kg; the P being from either orthophosphoric acid or food grade dicalcium phosphate. 2. Both sorghums depressed growth and food:gain ratio and increased the incidence of locomotor disorder to about 0.50 (maize control = 0). Sorghum from Sudan, with higher concentrations of both tannin and phytate, caused more severe anti-nutritive effects than sorghum from Egypt. 3. Within the limits of statistical significance the growth depressing effect of sorghum was completely reversed by extra P. With the more toxic Sudanese sorghum this amelioration was numerically less than complete (growth = 0.94, maize control = 1). Locomotor disorders were also virtually, but not completely, eliminated by phosphorus treatment. 4. Treatment of sorghum by dry-mixing with dicalcium phosphate could form the basis of a simple and economic method for extending the use of high-tannin sorghum in poultry foods. The mode of action of the treatment remains to be determined.
Complementary feeding is a transition of the baby's intake over 6 months to meet the
nutritional needs in addition to breast milk. Complementary feeding should contain
complete nutritional components especially in minerals. Minerals are elements needed by
the body for the overall body function. Children require calcium (Ca), iron (Fe), and zinc
(Zn) for their body growth to prevent stunting. This study was aimed to analyse Ca, Fe
and Zn content in the formulated fish protein hydrolysate (FPH) complementary feeding
porridge. A total of three formulations were produced namely F1, F2 and F3 and analysed
for mineral content following AOAC method 999.11. From the analysis, F3 had the
highest Fe content (38.547 mg/100 g) and Zn content (5.751 mg/100 g) while F1 had the
highest Ca content (65.152 mg/100 g). Overall, F3 had the best mineral content to be
formulated as a suitable FPH complementary feeding instant powder.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
