dc.description.abstractThe size and number of adipocytes of different fat depots was studied in 45 male lambs of the Rasa Aragonesa breed, distributed in three groups of 15 lambs (G12, G24, G36), slaughtered respectively at l 1.7 0.67,24.5 0.57 and 35.8 ? 1.74 kg live weight (LW) and at an age of 32 5, 89 8 and 123 & 8 days. G12 lambs were slaughtered on the day of weaning, G24 and G36 lambs were weaned respectively at 16.2 & 1.32 and 18.3 r 2.46 kg LW and were fed from then onwards on concentrated fodder and barley straw ad libitum until they were slaughtered. The results obtained show that there is a significant increase in the amount of fat deposited in three internal (omental, mesenteric and kidney knob and channel) fat depots as the LW at slaughter increases (P<O.Ol). A similar phenomenon occurs in the size of the adipocytes, hypertrophy being more evident between 24 and 36 kg (Px0.01) than between 12 and 24 kg, except in the intermuscular fat depot, where the differences were between the two most extreme weights (P<O.Ol). The number of adipocytes in the omental and mesenteric fat depots increased significantly during the period of the study while no variation occurred in the kidney knob and channel fat depot during the same period.es
dc.description.abstract"Variation de la taille et Aragonesa'! On a étudié la taille et le nombre des adipocytes de différents tissus adipeux chez 45 agneaux 3 groupes de 15 agneaux (G12, G24, G36), abattus respectivement à 11,7 0,67; 24,5 0,57 et 35,8 1,74 kg de poids vif (PV) et 32 5; 89 8 y 123 2 8 jours d'âge. Les agneaux du G12 ont été abattus le jour du sevrage; ceux du G24 et du G36 ont été sevrés respectivementà 16,2 -+ 1,32 y 18,3 2 2,46 kg de PV, et ont eu à leur disposition de l'aliment concentré et de la paille d'orge "ad libitum" jusqu'au le moment de l'abattage. Les résultats obtenus montrent une augmentation significative de la quantité de graisse deposée dans les trois dépôts gras internes (omental, mésentérique, pelvico-rénal) au fur età mesure de l'augmentation du PV d'abattage (P<O,OI). Des résultats semblables ont été trouvés avec la taille des adipocytes car elle augmente avec le PL( l'hypertrophie étant plus marquée entre 24 et 36 kg (P<O,OI) qu' entre 12 et 24 kg, sauf dans le tissu intermusculaire dans lequel les différences ont été entre les deux poids extrêmes (P<O,Ol). Le nombre des adipocytes dans les tissus omental et mésentérique a augmenté significativement pendant la période étudiée (P<O,OI), tandis que dans le tissu pelvico-rénal il n'y a pas eu de variation pendant cette période.es
