The effect of providing Moringa oleifera leaf meal in the diet on the semen quality of cross-bred Landrace boars

The research aims to examine the impact of providing Moringa oleifera leaf meal (MLM) in the diet on the quality of Landrace-cross boar semen, as well as to determine the optimal shelf life of semen from Landrace-cross boar. The design used was a completely random design with a split time pattern. The treatments consisted of: Landrace-cross-bred boar fed without Moringa leaf meal (P0) and Landrace-cross-bred boar fed with Moringa leaf meal (P1). Semen observations were carried out every 12 hours, starting from the 0^th hour to the 72^nd hour for both treatments and repetitions were carried out three times for each observation. The results of this study indicate that the provision of Moringa leaf flour in the diet for Landrace-cross boar has a positive impact on the quality and quantity of semen, especially in increasing sperm volume, motility, viability and concentration. It was concluded that giving 1% Moringa oleifera leaf meal in feed had a positive effect in maintaining sperm quality over a certain period of time, especially when it was fresh or at the beginning of storage.
