| Biologische landbouw streeft naar het sluiten van kringlopen op regionaal en bedrijfsniveau. Voor gevogelte moet 20% van het veevoeder afkomstig zijn van het eigen landbouwbedrijf of van een landbouwbedrijf uit de regio. Vlaamse biologische leghennenbedrijven hebben, naast de vrije uitloop, meestal geen extra ruimte die kan dienen voor het telen van voedergewassen of om zelf een gedeelte van de kippenmest te plaatsen. Om te kunnen voldoen aan de regionaliteitsvoorwaarde voor het voeder zullen zij op zoek moeten gaan naar samenwerkingsverbanden op regionaal niveau om kringlopen te sluiten. De bedrijven die wel extra ruimte hebben, geven aan dat ze nood hebben aan advies voor de mogelijkheden op hun bedrijf. Deze CCBT-studie van Proefbedrijf Pluimvee en... |

| Especially in areas with suboptimal conditions for the cultivation of soybeans, homegrown grain legumes, like faba beans and field peas, are very important protein feedstuffs for monogastric animals, like swine and poultry, in organic farming. Homegrown grain legumes contribute to the circular ecology of organic farms and add to the supply of essential amino acids to the diet. However, their value is not only determined by the crude protein content and amino acid profile but also by the bioavailability of crude protein and amino acids. Since only precaecally absorbed amino acids are potentially available in the metabolism, the precaecal digestibility of the crude protein and the amino acids can give a hint on their bioavailability. The aim of the study... |

| A linear regression approach was used to determine the precaecal digestibility of organic field beans and field peas in young broiler chickens. Diets with field beans of the variety Taifun (283 g crude protein/kg DM) and field peas of the variety Alvesta (173 g crude protein/kg DM) in three inclusion rates (30, 50, and 70%) were fed ad libitum to 15- to 21-day-old broiler chickens. Digesta was sampled pen-wise and obtained from the gastro-intestinal tract between Meckel’s diverticulum and 2 cm anterior to the ileo-caeco-colonic junction. Despite the high inclusion rates of the test feedstuffs, all diets were accepted by the birds. Feed intake and body mass gain, as well as precaecal crude protein and amino acid digestibility, were higher in chickens fed... |
