EFFECT OF OMEGA 3 ON THE REPRODUCTIVE PERFORMANCE OF THE ALGERIAN SYNTHETIC RABBIT IN ARTIFICIAL INSEMINATION
In the present work of the pubescent and immature rabbit does of the Algerian synthetic strain (ITELV 2006), the animals received a supplement of omega 3 of animal origin (fish oil) or vegetable origin (linseed) for 3 months (2 months before AI and 1 month during pregnancy). The females were followed until parturition in order to study the effect of omega 3 on their reproductive performance (fertility, prolificacy and stillbirth). Comparison of data between the six lots (Control puberts (CP), Control peripubertal (CPE), Linen grains pubertal (LGP), Linen grains peripubertal (LGPE), Fish oil puberts (FOP) and Fish oil peripubertal (FOPE)) for parameters of born deaths (BD), fertility and stillbirth rates showed no significant difference (P>0.05). Whereas for total births (TB), live births (LB) and weaner births (WB), the differences are significant (P<0.05). A very marked improvement in prolificity has been achieved by the incorporation of fish oil and flaxseed into the feed of the rabbits. In fact, the females of these two lots recorded the highest values (10.37 TB, 9.87LB, 9.3 WB and 10.44 TB, 9.77LB, 8.77WB respectively for FOPE and LGPE), as opposed to the unpunished rabbits of the control lot which gave the lowest numbers (7.14TB, 6.57LB and 6.57WB).
