| Observations from studies involving embryo transfers from ewes with contrasting feed intake during the peri-conception period suggest that the environment of the preimplantation embryo plays a significant role in establishing myogenic potential and, therefore, influences subsequent muscle development (1). The aim of the present study was to investigate whether altering environment of the embryo by altering maternal feed intake during the peri-conception period influences subsequent muscle development on the fetal sheep following natural mating. The experimental Karayaka breed ewes with a synchronised oestrus were fed roughage and concentrate diet (11.3 MJME/kg dry matter) at either 1.4× maintenance (H; high) or 0.5× maintenance (L; low) from 4 to 6 days before until 7 days after mating in individual pen. A total of 11 fetuses were collected on day 90 of gestation and placental weights, fetal body dimensions, fetal femur and tibia lengths, fetal organ and muscle weights were recorded. The numbers, type and size of muscle fibres in longissimus dorsi (LD), semitendinosus (ST) and semimembranosus (SM) muscles were determined. Maternal feed intake did not influence placental weights, fetal weights, body dimensions, organ developments and muscle weights in fetus. The ratio of secondary to primary fibres (7.6±0.58) in fetal LD muscle samples from low maternal feed intake group was lower than those (9.2±2.75) in high maternal feed intake group (P= 0.07). Similarly a lower ratio of secondary to primary fibres in fetal ST muscles but not in SM muscles was observed in low maternal feed intake group (7.14±1.09 vs. 8.93±2.18; P= 0.12 … |
