Effect of Water Extract of Maringa Olivera Leaves on some Characteristics of Goats Epididymal Sperms Under Cooling Conditions

Abstract

Abstract The current study was conducted at the postgraduate laboratories, Agriculture College, Al-Muthanna University, during the period between January 5, 2021 to May 29, 2022, to determine the effect of the water extract of Moringa olivera leaves on some characteristics of goats epididymal sperms under cooling conditions for different periods. The water extract of Moringa, Olivera leaves was prepared and stored in the refrigerator until the time of uses, the epididymal sperms were obtained from the slaughtered goats testes in the local abattoir of Al-Muthanna Governorate, and transferred immediately to the laboratory to collect the epididymal sperms from the tail of epididymis and extended by Tris extender contains different concentrations of water extract of Maringa Olivera (0.02 and 0.03)%. The results showed that the water extract of Moringa led to a significant increase (P≤0.05) on the individual motility of sperms and the hyper osmosis swelling test (HOST), with significantly decreased on percentage of abnormal and dead sperms. The increase of the time of cooling leads to a significant decrease on the individual motility of sperms and the HOST, with a significant increase on the abnormal and dead sperm. The interaction between the level of water extract of Moringa olivera and the cooling periods, there was a significant effect on the individual motility of sperms, while the interaction did not significantly affect to the abnormal and dead sperm as well as the HOST. It was concluded that the water extract of Moringa Olivera leaves improved the characteristics of goats epididymal sperms under cooling conditions.
