Behavioural indicators of range use in four broiler strains
Free-range systems provide an outdoor range for broilers to give them the possibility to express a higher frequency and a wider range of behaviours, such as exploration, compared with those raised indoors. Greater variability in outdoor range use between individuals of the same flock is often reported. Individual variation in range use may result from […]
Effects of riboflavin supplementation level on health, performance, and fertility of organic broiler parent stock and their chicks
Data from breeder hens and chicks are particularly critical for the development of vitamin B2 recommendations for organic poultry. To test safe thresholds of supplementation, 100 breeder hens (Hubbard JA 57 K) and ten cockerels were allocated to ten housing groups, with each receiving supplementation of either 4.0 (treatment CON) or 2.5 mg (treatment RED) riboflavin per kg feed. […]

RELACS – Improving inputs for organic farming – Data from breeder hens and chicks are particularly critical for the development of vitamin B2 recommendations for organic poultry.

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 […]
Integrazione di vitamina B2 e riduzione del rame in agricoltura biologica – Nuovi ‘abstract pratici’ dal progetto RELACS
Il progetto RELACS ha recentemente pubblicato tre nuovi ‘abstract pratici’ (linee guida pratiche) su: Integrazione di vitamina B2 per galline ovaiole e chiocce nei sistemi avicoli biologici Raccomandazioni per i supplementi di vitamina B2 nei polli da carne biologici a crescita lenta Strategie di riduzione del rame in viticoltura Queste linee guida pratiche rivolte agli […]
‘Organic Farm Knowledge’: disponibili cinque nuovi strumenti specifici dedicati all’allevamento avicolo
L’istituto di ricerca FIBL, partner del progetto ‘Organic Farm Knowledge’, ha messo a punto cinque nuovi strumenti che mettono in evidenza quali sono gli aspetti che rendono vincente un allevamento di pollame biologico. Questi cinque strumenti sono ora disponibili per il download nell’ambito del progetto. Attraverso di loro è possibile saperne di più sulle galline […]
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 […]
Feeding strategies for organic broiler chickens
Organic broilers grow slower than conventional birds and so producers face the challenge of feeding quality feed components at lower concentrations. Feed needs to fulfil the amino acid and energy requirements of broilers for efficient growth and development, but growth is slower. Choice of feeding, access to range and forages can increase the utilisation of […]
