Effects of gestational maternal undernutrition on growth, carcass composition and meat quality of rabbit offspring.

An experiment was conducted in order to evaluate the effects of gestational undernutrition of rabbit does on growth, carcass composition and meat quality of the offsprings. Thirty primiparous non lactating rabbit does were artificially inseminated and randomly divided in three treatment groups: Control (C; fed to 100% of maintenance requirements throughout gestation, n = 10), early undernourished (EU; fed to 50% of maintenance requirements during days 7-19 of gestation, n = 10) and late undernourished (LU; fed to 50% of maintenance requirements during days 20-27 of gestation, n = 10). During the 4th week of the gestation period, LU does significantly lost weight compared to C and EU groups (P<0.

Severe maternal undernutrition and post-weaning behavior of rabbits.

The objective of the present experiment was to investigate the implications of severe maternal undernutrition on the post-weaning behavior of rabbits. Thirty two does were randomly assigned to four groups: the control group (C) that was fed 100% of the recommended energy maintenance requirements throughout pregnancy and lactation and the U1, U2 and U3 groups that were fed 50% of the recommended energy maintenance requirements between the 6th and the 19th day of pregnancy, between the 20th and the 27th day of pregnancy and between the 3rd and the 10th day of lactation, respectively. At the age of 50 and 65 days, behavior of rabbits in cages was recorded and rabbits were further subjected to an open-field test; a paradigm used as an indicator of fear and emotional distress.
