RESUMO

INTRODUCTION: Roughage alternatives for equine nutrition must be found due to the increasing climatic challenges. The aim of this study was to examine the nutrient composition and feed hygiene of alfalfa hay in comparison to meadow hay and to investigate the acceptance, weight development and faecal quality of broodmares fed alfalfa hay. The feed used was examined for nutrient content and hygiene status according to the standards of the Verband Deutscher Landwirtschaftlicher Untersuchungs- und Forschungsanstalten (VDLUFA). Twenty adult pregnant warmblood mares were fed in two groups (n=10) with a defined amount of alfalfa hay or meadow hay in a controlled study with a wash-out phase and subsequent crossing of the groups. Alfalfa hay intake was observed daily, and bodyweight was recorded weekly. On day 0 (T0) and day 28 (T28) of each study period, fresh faecal samples were collected and analyzed for pH, dry matter (DM) and short-chain fatty acids (SCFA). The hygienic quality of the alfalfa and meadow hay was slightly reduced (quality level II) on average. The intake of the alfalfa hay was carried out in all mares without backweighing. The median crude protein content of the alfalfa hay was 134 g/kg DM, the median calcium content was 13,9 g/kg DM and the median magnesium content was 1,50 g/kg DM. Horses fed alfalfa showed a significantly greater median percent weight gain of 3,25 % compared to hay-fed horses (1,68 %) (p.


INTRODUCTION: En raison des défis climatiques croissants, des alternatives de fourrage grossier doivent être trouvées dans l'alimentation des chevaux. L'objectif de cette étude était de vérifier la composition nutritionnelle et l'hygiène alimentaire du foin de luzerne par rapport au foin de prairie, ainsi que d'étudier l'acceptance, l'évolution du poids et la qualité des fèces chez des juments d'élevage nourries au foin de luzerne. La teneur en nutriments et le statut hygiénique des aliments utilisés ont été analysés selon les méthodes de l'Association allemande des instituts de recherche et d'analyse agricoles (VDLUFA). Vingt juments adultes de sang en gestation ont été réparties en deux groupes (n=10) dans le cadre d'une étude contrôlée avec une phase de wash-out suivie d'un croisement des groupes avec une quantité définie de foin de luzerne ou de foin de prairie. L'acceptance concernant l'ingestion de foin de luzerne a été observée quotidiennement, le relevé de la masse corporelle a été effectué chaque semaine. Au jour 0 (J0) et au jour 28 (J28) de chaque période d'essai, des échantillons de fèces fraîchement émis ont été collectés et analysés pour en déterminer le pH, le taux de matière sèche (MS) et la teneur en acides gras à chaîne courte (AGCC). La qualité hygiénique du foin de luzerne et de prairie était en moyenne légèrement dégradée (niveau de qualité II). Le foin de luzerne a été ingéré par toutes les juments sans pesée de retour. La teneur médiane en protéines brutes du foin de luzerne était de 134 g/kg de MS, sa teneur médiane en calcium de 13,9 g/kg de MS et sa teneur médiane en magnésium de 1,5 g/kg de MS. Les chevaux nourris à la luzerne ont présenté un pourcentage de gain de poids médian significativement plus élevé (3,25 %) que ceux nourris au foin de prairie (1,68 %) (p.

RESUMO

To evaluate safety and efficacy of donor lymphocyte infusions (DLI), derived from frozen aliquots of the original G-CSF-stimulated graft after allogeneic PBSCT from unrelated donors, data of 121 patients with hematological malignancies treated with DLIs were retrospectively analyzed. Indications for PBSCT were AML/myelodysplastic syndrome (n=63/8), ALL (n=17), lymphoma (n=13), multiple myeloma (n=10) and myeloproliferative syndrome (n=10). Reasons for DLI were hematological relapse (n=81), molecular and/or cytogenetic relapse (n=5), mixed chimerism (n=22) and prophylactic DLI in high-risk patients (n=13). DLIs were well tolerated with no acute adverse reactions. DLI-induced acute-type GvHD (aGvHD) was observed in 19 patients and chronic-type GvHD (cGvHD) developed in 14 patients. Three patients died of GvHD complications. DLI induced CR, complete chimerism or PR in 34 patients; 24 patients had stable disease, 50 patients progressed and 13 patients were not evaluable for response. Objective response was more obvious for molecular relapse (5/5) or mixed chimerism (14/22) compared with hematological relapse (13/81). Median survival after first DLI was 10.4 months (95% confidence interval: 4.4-26.0). Cryopreserved G-CSF-stimulated DLI, derived from allogeneic grafts are safe and immunoreactive, and can be applied early in case of mixed chimerism and molecular or cytogenetic relapse.
