Riboflavin for laying hens fed organic winter diets: effects of different supplementation rates on health, performance and egg quality

For reasons of aspired naturalness and cost reduction, vitamin additions should be kept low in organic livestock systems. To define safe lower threshold levels of riboflavin supplementation in organic poultry feeding, 135 hybrid layers were allocated to three dietary treatments supplemented with either 4.5 (R4.5), 3.0 (R3.0) or 1.5 mg (R1.5) GMO-free riboflavin added per kg feed. This resulted in total measured concentration averages of 5.0, 4.5, and 3.1 mg kg−1 feed for R4.5, R3.0 and R1.5, respectively.

Ricerca dall’India: i concimi biologici aiutano i pomodori a rimanere freschi più a lungo

I pomodori prodotti in terreni concimati con concimi organici fermentati rimangono più freschi più a lungo e presentano una maggiore consistenza, maggiori quantità di vitamina C e antiossidanti al momento del raccolto rispetto a quelli coltivati con fertilizzanti sintetici: è quanto indica un recente studio indiano, che è possibile scaricare QUI.

Postharvest Quality and Storability of Organically Versus Conventionally Grown Tomatoes: A Comparative Approach

Published in “Biology and Life Sciences Forum” -  In various parts of India, tomatoes are grown using eco-friendly indigenous organic manures prepared from cow products, for sustainable food production by small and marginal farmers. The main objective of the study was to compare the postharvest quality characteristics and storability between organically grown tomatoes using indigenous organic manures and those grown conventionally.
