The Effects of Selenium Supplementation on the Production of Spermatozoa and Semen Quality of Riverine Buffaloes
Journal Title: JOURNAL OF BIOLOGICAL ENGINEERING RESEARCH AND REVIEW - Year 2018, Vol 5, Issue 2
Abstract
This study determined the influence of different concentrations of organic selenium in the production of spermatozoa and semen quality of riverine buffaloes. Thirty (30) riverine buffalo bulls used for semen production at the National Bull Farm of the Philippine Carabao Center were allotted into six treatment groups. The first treatment (T1) with no supplementary selenium served as the negative control. The second (T2) and the third (T3) treatments were given 10% and 5% below the published selenium requirement of bulls, respectively. The fourth treatment (T4) serving as the positive control was given the normal level of selenium while the fifth (T5) and sixth (T6) groups were supplemented with 5% and 10% above the required selenium, respectively. The buffalo bulls were fed with rations composed of corn silage, rice straw, concentrates and molasses for three months under intensive system of management. Semen collection was done 2x a week using artificial vagina method and the semen volume, color, pH, sperm motility, sperm concentration and sperm morphology were evaluated. The results showed that T5 produced the highest values on semen volume (3.68 ml), sperm motility (71.82%), concentration (126.84 x 107) and viability (82.91%), respectively. This treatment has the lowest abnormal sperms of 10.55% when compared among the treatments with 22.89%. Overall results further revealed that the average sperm production and semen quality were improved by the different levels of dietary selenium supplementation. The color and pH of the semen collected from donor bulls were not significantly affected by selenium supplementation but the data gathered agreed with the published values.
