Resumen
A total of 46 rabbit females were used to evaluate the evolution of body-weight, perirrenal fat thickness, as estimation of body condition, and NEFAs from 12 weeks of age to 4th delivery when a semi-intensive reproductive rhythm (mating 11 days after delivery) was applied. The body-weight of the female increased to 12th day of the second gestation thereafter remained stable at 4 kg. At the beginning of reproductive life, the rabbit females have around 4 mm of perirrenal fat thickness. Then, from the second mating (5.05 mm) it progressively increased until the third parity (8.12 mm.). The NEFA concentration was maximum at delivery (around 0.40 mmol/L), and lower values were obtained at mating and during gestation, regardless of the reproductive cycle. In conclusion, the females under semi-intensive reproductive rhythm progressively increased perirrenal fat thickness and body weight to the 2nd reproductive cycle, and from that moment the rabbit females began to manage their body reserves depending on reproductive status.
