Effect of Adding Kojic Acid and Sodium Alginate to Semen Extender of Buffalo Bulls on some Biological and Bacteriological Parameters

Abstract

This experiment examined the effects of adding sodium alginate and Kojic acid as substitutes for conventional antibiotics to Skim milk extender on the characteristics of cryopreserved and frozen buffalo bull semen, as well as the evaluation of their additions as antibiotics that help lower the microbial load. Following the collection and dilution of the Skim milk extender, the experimental treatments were separated into five groups, as follows: T1: (control-) without adding any antibiotics; T2: (control+) adding the conventional antibiotics Gentamicin 0.4 IU and Tylosin 0.08 IU per 100 ml; T3: adding Kojic acid at (0.06 g/L) T4: adding sodium alginate at (0.6 mg/mL)T5: adding a combination of Kojic acid (0.06 g/liter) with sodium alginate (0.6 mg/ml) The diluted semen was cryopreserved in accordance with the recommended procedure, and the characteristics of the cryopreserved semen were then assessed. These characteristics included plasma membrane integrity and individual motility, as well as bacteriological tests that measured the total number of bacteria in the treatments, the total number of E. coli bacteria, and the total number of Staphylococcus bacteria for both cooled and frozen semen after 2 hours, 48 hours, 2 months, and 3 months post cryopreservation. The results of the study revealed There were significant enhancement differences (p 0.05) for the treatments T3, T4, and T5 in the percentages of individual motility and viability in comparison to the two control groups, as well as a significant reduction (p 0.05) in the total number of bacteria and the total number of E. coli and Staphylococcus bacteria for treatments T3, T4, and T5 after all periods of cooling and freezing in comparison with the two control groups. It is concluded from the current experiment that the addition of sodium alginate and kojic acid as an alternative substitute for commonly used antibiotics to the semen extender has a significant role in enhancing some characteristics of the buffalo bulls’ semen and helping to reduce the microbial load to a minimum.
