Abstract

One hundred and twenty seven rabbit does were fed ad libitum from rearing until 2nd weaning, two isofibrous, isoenergetic and isoproteic diets supplemented with two different fat sources: 3% lard for diet C (control) or 6% of a supplement (Optomega-50; Optivite International Ltd., España) containing a 50% of ether extract and 38% of n-3 polyunsaturated fatty acids for diet P (PUFA n-3). Does were inseminated at 4.5 months of age and then, at 32 days after the first parturition. Fertility and prolificacy were determined. Blood samples were obtained in 12 does of each group at -7, 0, 7, 14, 21 and 28 days of pregnancy to determine plasma progesterone. In addition, 10 litters from each group with 10-11 kits, one day old, were measured determining their length, and their biparietal and thoracic diameters. Feed intake and prolificacy were similar in both groups. Supplementation with PUFA n-3 improved fertility at second AI. Progesterone concentrations on day 7 and 14 of pregnancy in PUFA does, and the size of their kits at birth were also increased.
