In order to develop an organic broiler product with high ethical value, high meat quality and based on locally produced feed, we tested if a long period without high quality protein feed followed by a finishing period with a high quality protein ration would affect the meat quality. Two genotypes were included in the experiment (The Hubbard breed ‘JA757’ and the Sasso breed ‘T851’), and only female broilers were included. The chickens were raised in groups in a free range system with more than 10 square meters per chicken covered with grass and herbs. The chickens were offered free access to either an optimized organic concentrate ration (HP) or an organic ration based on locally produced ingredients (peas, rapeseed, lupine, wheat and oat) (LP). The... |

Production of organic beef from young cattle is not very developed in Denmark, in spite of a well-established organic dairy production that could deliver bull calves for use in organic beef production. Instead these calves are sold to conventional beef producers, because of low performance in organic production systems. The purpose of this study was to test a concept for production of organic beef based on crossbred animals from dairy cows sired with a beef breed. The results show that crossbred Limousine X Holstein bulls and heifers may be an alternative to purebred Holstein bulls in organic beef production of young cattle because of improved gain and carcass conformation, aroma and taste. However, the fatness and texture of the crossbred bulls need to... |

The organic rules require that bull calves are raised outdoor at least 6 months a year in Denmark and are fed at least 60% roughage of the total diet. These rules are a constraint for an organic production of beef based on the bull calves born in the organic dairy herds because of extra labor costs, expected lower growth rate, difficulties in raising bull calves outdoor, possibly lower meat quality and lack of sufficiently high organic premium payment for the carcass. Thus, the bull calves are sold for conventional fattening. The supply of organic beef from young cattle is concomitantly very limited. However, in order to obtain the necessary higher payment for beef from organic-raised young cattle, it is important that consumers like the beef from grass-... |

The objective of the present study was to compare growth performance, carcass quality characteristics, and production economy of 15 Danish Holstein bull (HB) calves, 15 Limousine x Danish Holstein crossbred bull (CB) calves and 15 Limousine x Danish Holstein crossbred heifer (CH) calves reared under organic conditions. Spring-born calves were purchased at private farms and at approximately 20 days of age with an average initial body weight of 52.9, 58.2 and 56.1 kg, (SEM 2.6) for HB, CB and CH, respectively. Calves were housed indoor until weaning at 3 months of age. Calves were gradually introduced to a grass-silage based ration from 3 to 4 months of age. From 4 to 7 months calves were kept on mix grass pasture of ryegrass and white clover. From 7 to 13.5... |

Scientific Workshop on Organic Pig Production, Hovborg Kro, Holmeåvej 2, 6682 Hovborg, DK June 12th and 13th 2013 Programme: June 12th 2013: 9-9.30: Coffee, bread, and welcome (Marianne Bonde, UHF) 9.30-10: Sandra Edwards (UK): Future challenges in organic pig production 10-11.30: Theme 1: Production of entire male pigs / Chaired by Jan Tind Sørensen The aim of organic pig production is to ensure high animal welfare and natural products. Banning castration is thus a logical step forward, but the risk of boar taint in the meat is a major barrier for marketing meat from entire male pigs. Is it possible to use genetic tools and breeding strategies to prevent boar taint? What is the effect of feeding, management, housing and hygiene? Is... |

The present experiment shows that there are no drawbacks in finishing young bull calves for 6 weeks on purely grass sward or purely herb-based sward in comparison with concentrates when it comes to meat and eating quality › The meat of grass- and herbs-fed calves has similar colour and sensory profile › Herbs has a positive effect on the ‘health-related’ quality as herbs increase the content of vitamins A and E, linoleic and α-linolenic acid and improves the n-6 :n-3 ratio |

ORGANIC MEAT FROM BEEF AND PORK TO FULFIL SOCIETY AND CONSUMER EXPECTATIONS Objective: The objective is to optimize the efficiency in organic meat production with respect for organic principles and product quality traits. Anticipated results and impact related to both science and society. Organic meat from pigs and cattle that that are produced efficiently and in a volume so it can contribute to eg. the 300.000 public meals and also become a profitable export product, because of exploration of specific muscle. characteristics and content of health beneficial composition – fatty acids and vitamins. |

We examined the eating quality of meat from spring-born crossbred Limousine x Holstein bulls (CB) and heifers (CH) compared with Holstein bulls (HB) raised over two grazing seasons on high-yielding pastures and slaughtered directly from pasture after the 2nd grazing season at a fixed slaughter age (16.9 months). The meat quality was evaluated by a nine-member trained sensory panel on an unstructured scale from 0 to 15, with 0 representing minor aroma and taste characteristics and tough meat and 15 representing intense aroma and taste characteristics as well as tender meat. The evaluation was done on M. longissimus dorsi (LD) and M. semimembranosus (SM) sampled from 8 HB, 8 CB and 8 CH animals 24 h post mortem and aged at 4C for additional 13 days. The... |

Produktionen af økologisk kød fra ungdyr er ikke særligt udbredt i Danmark til trods for et veletableret økologisk mælkeproduktionssystem, som egentlig godt kunne levere tyrekalvene til den økologiske kødproduktion. I stedet bliver disse kalve solgt til konventionelle kødproducenter på grund af lave udbytteresultater i de økologiske produktionssystemer. Formålet med dette projekt var at afprøve et koncept til production af økologisk kød fra ungkvæg baseret på krydsningsdyr fra malkekøer kødkvægstyre. Resultaterne viser, at kvie- og ungtyrekrydsninger af Limousine x Holstein kan være et alternativ til renracede Holstein ungtyre i økologisk oksekødsproduktion grundet den øgede tilvækst og form-klassificering, aroma og smag hos krydsningsdyrene. Dog er der... |
