Effect of Cod Liver Oil Supplementation in Feed on the Haematological Values and Concentration of Epididymis Spermatozoa of Local Rabbits

Abstract

This the study aimed to determine the effect of cod liver oil supplementation in commercial feed on the haematological values and concentration of epididymis spermatozoa of local rabbits. The experimental design used was Completely Randomized Design with four feed treatments, i.e. commercial feed without supplementation of cod liver oil (P0) as control, commercial feed supplemented by 1.5% (R1), 3% (R2), and 4.5% (R3) of cod liver oil. Each trial consisted of eight rabbits and feed experiment was given starting by 13 weeks to 26 weeks of years old. The variables measured were the count of red blood cell (RBC), white blood cell (WBC), platelets, haemoglobin (Hb), packed cell volume (PCV), and concentration of epididymis spermatozoa of local rabbits. The results showed that supplementation of cod liver oil with a different grade in feed commercial had a significant effect (P<0.05) on the haematological values and concentration of epididymis spermatozoa of local rabbits. It can be concluded that cod liver oil supplementation in commercial feed at 4.5% level capable maintain normal haematological values and can increase the concentration of epididymis spermatozoa of local rabbits.
