Abstract

The aim of this study is to investigate the potential of glucose, glycine, and a combination of glucose and glycine supplemented into Ringer’s lactate extender on the quality of pre- and post-cryopreservation of semen of local chickens. Semen samples were collected from KUB roosters. The research procedures involved formulation of the extender, semen collection, assessment of fresh semen, dilution, packaging, cryopreservation, storage, and subsequent assessment of cryopreserved semen. Parameters assessed in fresh, pre-cryopreservation, and post-thawed semen using computer-assisted semen analysis (CASA), included motility (total motility, progressive, static, and slow motilities), kinematics, spermatozoa morphology, malondialdehyde (MDA) concentration, and scanning electron microscopy (SEM). There were four treatments: T1= control, T2= 50 mM glucose, T3= 60 mM glycine, and T4= a combination of 50 mM glucose and 60 mM glycine. Each treatment was repeated 10 times. The results showed that the addition of 60 mM glycine and the combination of 50 mM glucose and 60 mM glycine effectively preserved total motility, maintained progressive motility, and reduced damage to the bent tail during the equilibration process (prior to cryopreservation). In addition, total motility, progressive motility, DAP, DSL, DCL, VAP, VSL, VCL, STR, and LIN were significantly increased after thawing. This approach also minimized the formation of MDA. Furthermore, observations using SEM showed comparatively more intact acrosomes compared to the other treatments. In conclusion, the addition of 60 mM glycine and a combination of 60 mM glycine and 50 mM glucose to Ringer’s lactate-egg yolk extender proved to be effective in preserving the quality of domestic chicken spermatozoa during semen cryopreservation.

Abstract

This study aimed to examine the effect of adding different concentrations of sorbitol to the Ringer’s lactate-egg yolk (RLEY) diluent on the quality of Gaga roosters’ semen during cold storage. A completely randomized design was used with 10 replicates and 4 levels of diluent treatment, including control, 1%, 2%, and 3% sorbitol. Semen was collected using a massage method, followed by fresh semen evaluation and dilution with a ratio of 1:5. Semen was stored at a cold temperature (5 ºC) and observed after 0, 24, 48, and 72 hours. The variables observed were semen pH, motility, kinematics, viability, plasma membrane integrity, acrosome integrity, malondialdehyde (MDA), and intracellular calcium ion (Ca2+) concentrations of sperm. All data were analyzed using analysis of variance (ANOVA). Subsequently, the evaluation of sperm mitochondrial activity and DNA damage was carried out, and the data were analyzed using the T-test. The results showed that treatment with sorbitol in the diluent had no effect on semen pH, kinematics (except straightness), acrosomal cap integrity, DNA damage, mitochondrial activity, and MDA concentration. However, sorbitol concentrations significantly affect (p<0.05) total motility, progressive motility, static motility, STR, viability, plasma membrane integrity, and intracellular Ca2+. In conclusion, the addition of 1-3% sorbitol preserves the quality of Gaga roosters’ semen during 72 hours of cold storage.
