  1. THREONINE : AN ESSENTIAL AMINO ACID NOT FREQUENTLY USED TILL NOW IN RABBIT FEEDS FORMULATION. A REVIEW

    Colin, M.; Ghezal-Triki, N.
    [EN] Lactating doe and growing-finishing rabbit threonine requirements have been studied through a review of the original researches dealing with this topic. Threonine is confirmad as being an essential amino acid to rabbit milk production and growth. Threonine requirement can be evaluated at 0.64% of the feed for the lactating doe and at 0.60% for the growing-finishing rabbit. However, growth and milk production variations with dietary threonine level remain limitad. Expressed in percentage of the crude protein, the threonine requirement of the rabbit (3.7%) is higher than those for the pig or chicken. This fact may be a consequence of the high threonine level of rabbit meat. This study...

  3. FEEDING RYEGRASS HAY TO GROWING RABBITS, A NOTE

    Fernandez-Carmona, J.; Cervera, C.; Moya, J.; Pascual Amorós, Juan José
    [EN] Digestibility of ryegrass hay (18% crude protein and 18.9% crude fibre) was determined with 11 three-way crossbred New Zealand x Californian growing rabbits, using a 95% ryegrass die! +2% animal fat and 3% amino-acids, vitamins and minerals. Amino acids composition of diet and of the ryegrass was given. With the same diet, twenty-eight rabbits were used from 42 to 70 days of age to study the growth performance and carcass parameters. The ryegrass hay used in the present work showed high digestible energy (10.3 MJ kg·1 DM) and digestible protein (119 g kg·1 DM) contents. Avera~e daily gain, feed intake and live weight at 70 days were...

  6. EFFECT OF DIFFERENT FEEDING LEVELS DURING REARING AND AGE AT FIRST INSEMINATION ON BODY DEVELOPMENT, BODY COMPOSITION, AND PUBERTY CHARACTERISTICS OF RABBIT DOES

    Rommers, J.M.; Meijerhof, R.; Noordhuizen, J.P.T.M; Kemp, B.
    [EN] An experiment was performed to study the effect of feeding leve! during rearing and age at first mating on body growth, body development and puberty of rabbit does. Experiment started at six weeks of age, using 64 animals of a strain of New-Zealand White rabbits. Feeding level was either ad libitum (AL) or restricted (R) and animals were inseminated at 14.5 or 17.5 weeks of age. In Ranimals, feed restriction was up to 58% of AL from 6 to 12 weeks of age. From 12 weeks of age onwards, feeding level was steadily increased to stimulate body growth and sexual development. Average feeding level of R-animals during rearing...
