Lactic acid bacteria supplements for organic broilers (OK-Net EcoFeed practice abstract)
A healthy intestinal system in broilers is important to ensure optimal growth and lower mortality. Adding lactic acid bacteria to drinking water or feeding maize silage, could improve performance and have a positive effect on the digestibility of nutrients. Three treatments were tested in an on-farm study with broilers in mobile houses (Figure 1). One […]
Clover-grass protein by bio-refining: nutrient composition and shelf life (OK-Net EcoFeed practice abstract)
Alternative protein sources can increase the use of locally produced protein, supporting the transition to 100% organic feeding. Clover-grass concentrate has a high protein content with a good amino acid profile for poultry. It is necessary to dry the green protein paste to maintain a good quality, but the drying process is expensive. Anaerobic storage […]
Progetto RELACS: integrazione di vitamina B2 per il pollame biologico, nuovi valori
Il progetto RELACS ha messo a punto delle raccomandazioni per l’integrazione di vitamina B2 nei polli da carne biologici a crescita lenta e per le galline ovaiole nei sistemi avicoli biologici. Il problema è sostanzialmente la necessità della vitamina B2 (riboflavina) come supplemento nelle diete del pollame. Nel settore biologico, le fonti/i supplementi senza OGM […]
Demand-oriented riboflavin supply of organic broiler using a feed material from fermentation of Ashbya gossypii
Alternatives to riboflavin (vitamin B2) production by recombinant microorganisms are needed in organic poultry production, but are cost-intensive, so that a demand-oriented riboflavin supply is necessary. Details on the riboflavin requirements of organic poultry are not available. A feed material with high native riboflavin content from fermentation of the filamentous fungus Ashbya gossypii was studied. Two runs […]
Antimicrobial Susceptibility of Escherichia coli and ESBL-Producing Escherichia coli Diffusion in Conventional, Organic and Antibiotic-Free Meat Chickens at Slaughter
As a result of public health concerns regarding antimicrobial resistance in animal-based food products, conventional poultry companies have turned to ‘raised without antibiotics’ (ABF) and organic farming systems. In this work, we evaluated the influence of rearing systems on antimicrobial susceptibility in E. coli and extended-spectrum β-lactamase (ESLB) E. coli diffusion in conventional (C), organic (O) and antibiotic free […]
Recommendations for using soy-based feedstuffs for poultry production (OK-Net Ecofeed Practice Abstract)
Soya is one of the most important sources of protein in poultry feeding. However, the high crude protein content alone is not sufficient to meet the special needs of poultry on essential amino acids. They need to be supplemented with other components to get optimal amounts and ratios. In poultry, the feeding of raw soya […]
Focus on the amino acid content of energy feedstuff components (OK-Net Ecofeed Practice Abstract)
Switching poultry rations from 95 % to 100 % organic feed can lead to a reduction in the use of home-grown and regional feed. Currently, conventional maize gluten and conventional potato protein are replaced by organic oilcake (soya, sunflower, rapeseed, sesame). Oilcake has a comparatively low content of important amino acids such as methionine and […]
