The aim of the study was to assess the effect of body condition score on tissue and metabolic characteristics of the adipose depots in sheep of Rasa Aragonesa breed. Ewes were uniformly assigned according to their body condition score (BCS) (scale 0 to 5), to four groups: 0.75–1.75, 2–2.75, 3–3.75, and 4–4.5. The amount of fat and the adipocyte size in the different adipose depots increased as BCS did (P < 0.001) while the number of adipocytes did not change. The greatest ability to accumulate or mobilize fat was the subcutaneous depot (slope of the regression between amount of fat and BCS, b = 1.92; P < 0.001). Fatty acid synthase (FAS) lipogenic enzyme activity was affected by BCS, while G3-PDH and G6-PDH activities were not. Key words: Adipose tissue, body condition score, adipocyte size, lipogenic enzyme activity, ewes

Although body condition score was not significantly different between light (<55 kg, n = 6) and heavy (≥60 kg, n = 70 ewes at mating, it declined between Day 30 and Day 90 of gestation in light but not heavy ewes, and remained lower up to term. All ewes bore twins, delivered near term (Days 144–146) by Caesarean section. One lamb was immediately placed into a warm (30°C; WD) and its twin into a cool (15°C; CD) ambient temperature, and tissues were sampled at 0·5 h or 6 h. All CD lambs born to light ewes exhibited hypothermia and/or respiratory failure and did not survive longer than 30 min; these symptoms were not observed in their WD twins or any lamb born to heavy ewes. Total lamb birth weight, placental weight and fetal cotyledonary weight were lower with light than with heavy ewes. Lambs born to light ewes had less perirenal adipose tissue and smaller liver, heart, kidneys, brain, adrenals and thyroid, although their heart, brain and pancreas represented a larger proportion of total bodyweight; pancreas weight was similar to that in lambs born to heavy ewes. Hence, maternal bodyweight critically influences placental weight and lamb size and survival after birth.
