Abstract

In this study 48 male albino rats having an average body weight of 40±4 g and average age of 3 weeks were used to determine the effects of palm oil (PO) and palm kernel oil (PKO) supplementation on the growth performance and testicular function in albino rats. The rats were divided into four groups of nine rats each and further replicated three times, with three rats per replicate in a completely randomized design (CRD). Group II and III rats were given standard rat feed supplemented with 8 ml/kg of PO and PKO respectively as part of the energy source in their diet. Group I and IV were the control groups and did not receive the oils in their diets, however, 100mg/kg/day of vitamin E was included in the diet of the Group IV rats as the positive control. The effect of freshly included oils on growth performance and testicular development was evaluated after 42 days of feeding at two weekly intervals of samples collection, bearing in mind that the spermatic cycle was 9 – 12 days. Effects on seminiferous tubules were assessed and also epididymal sperm reserves. The group that received PKO not only showed destroyed matured sperm cells but also destroyed developing sperm cells. In the study vitamin E and palm oil showed better result on semen qualities while in body weight palm oil had reduced body weight compared to the palm kernel oil, vitamin E and control groups, where the weights were significantly increased. Also, the histopathological observations showed degeneration in the seminiferous tubule and Leydig cells in the palm kernel oil group especially at the first and second collection. Thus palm oil and vitamin E supplemented daily in diet might be helpful in promoting semen qualities and reproductive performance in animals.
