Organic meat production from Holstein calves born in dairy herds require that the bull calves are raised outdoor at least 6 months a year, and on large quantities of roughage in the diet. This study aimed at elucidating if Holstein bull calves fed either purely grass or purely herbs prior to slaughter would differ in meat quality traits, fatty acid composition and sensory profile and if they differed in quality aspects from concentrate-fed veal calves.

Temadagen var en dansksproget forlængelse af en videnskabelig workshop om økologisk svineproduktion, som blev holdt på engelsk dagen forud. (Temadagen afsluttedes desuden med det ene - af to halvårsmøder - for Friland) Temadagen gav producenter og andre interesserede mulighed for at få indblik i den nyeste forskning inden for økologisk svineproduktion. Folkene frafem igangværende forskningsprojekter var sammen om at arrangere dagen, som startede med besætningsbesøg hos Nicolaj Pedersen, Hovborg.

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...

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...

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-...

Production of organic beef from young cattle is not very developed in Denmark, in spite of a well-established organic dairy production with male off-spring. These calves are sold to conventional production, 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 experiment included a comparison between spring-born pure-bred Holstein bulls (HB), crossbred Limousin x Holstein bulls (CB) and heifers (CH), 15 of each group. After weaning the calves were raised outdoor on pasture the 1st summer and indoor on a low energy grass-haylage ration over winter followed by pasture the 2nd summer and slaughter at a...

Økologiske kyllinger på urter - vejen til høj dyrevelfærd (D.5.4)

Steenfeldt, S.; Horsted, K.; Therkildsen, M..

Slagtekyllinger vokser hurtigt, hvilket er en egenskab opnået gennem mange års avl og foderoptimering. Dette resulterer ofte i benproblemer og et lavt aktivitetsniveau, hvilket øger risikoen for sår og svidninger på fødderne. Ved brug af nye kyllingetyper med langsommere vækst og ændret fodringsstrategi forventes bedre velfærd, kyllinge-kød med ny spisekvalitet og bedre udnyttelse af føde fra udearealet.

Among many farmers, butchers and consumers, the expectation is that meat arising from grazing cattle generally is darker than meat from cattle primarily fed cereals. Without necessarily being the truth, this dogma is a constraint to the marketing of ‘green’ meat. In an attempt to increase the supply of organic meat from young cattle, we need to know which quality parameters are the characteristics for this type of meat, including colour characteristics.

Genotype as well as growth rate is important for the final meat texture in broilers. Texture of breast fillet can be optimised in broilers raised on locally produced protein sources with a short period of 2 weeks with free access to an optimised organic feed. This suggest that compensatory growth in broilers can be used to optimise the final texture of the meat – and may be a strategy to fulfill consumer expectations of organic broliers.

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...

Use of traditional breeds and free-range systems based on natural foraging may be one way to improve the quuality of organic pork in a broad sense and thereby justify the larger price.

Forsøg har vist, at græs/urte-fodring til økologiske slagtekalve i en to-måneders periode forud for slagtning kan forbedre fedtsyresammensætning og vitaminindholdet i kødet. Desuden giver fodringen mørt kød med en god smag og viser ingen tegn på, at kødet skulle blive mørkere. Disse resultater er vigtige i markedsføringen af økologisk produceret kalve- og oksekød.

Crossbred Limousine x Holstein bulls and heifers may be an alternative to purebred Holstein bulls in organic beef production of young cattle because of the improved gain, carcass conformation and taste, but the fatness and texture of the crossbred bulls need to be improved through changes in the production strategy, especially feeding prior to slaughter, and in the pre and post mortem handling.

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

Blandt mange landmænd, slagtere og forbrugere er forventningerne, at kød fra græssende kvæg er mørkere end kød fra kvæg primært fodret med kraftfoder. Dette er ikke nødvendigvis sandt, men dette dogme florerer og er en begrænsning i markedsføringen af "grønt" kød. For at kunne øge forbruget af økologisk kød fra ungkvæg er vi nødt til at vide,hvilke kvalitetsparametre og hvilke karakteristika, der er gældende for denne type af kød - herunder også kødfarve.

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...
