Abstract

Spermatozoa in fresh semen of Sapudi ram has a limited life span. The storage of semen in cold temperatures (5 °C) is intended to prolong the spermatozoa's life. However, storage in cold temperatures can lead to increased production of reactive oxygen species (ROS). This condition reduces the quality of spermatozoa. The purpose of this study was to determine the effect of alphatocopherol supplementation in skim milk-egg yolk extender on viability, motility, and plasma membrane integrity of Sapudi ram spermatozoa. Fresh semen derived from Sapudi ram was divided into four treatment groups. Control treatment (P0): semen was added in the extender of skim milkegg yolk without alpha-tocopherol. Three other treatments: P1, P2, and P3 semen were added in skim milk-egg yolk extender with the supplementation of 0.25, 0.5, and 1 gram alpha-tocopherol/ 100 mL extender, respectively. The results showed that the viability, motility, and integrity of the spermatozoa plasma membrane decreased gradually according to the storage length. Supplementation of skim milk-egg yolk extender with 0.5 gram of alpha-tocopherol/100 mL (P2) was able to maintain spermatozoa quality longer (p <0.05) than the control group. It can be concluded that alpha-tocopherol with a concentration of 0.5 g/100 mL of skim milk-egg yolk extender effectively maintains the quality of Sapudi ram spermatozoa in storage at 5 ° C.

Abstract

This study was conducted to determine the effect of crude protein tyrosine kinase (PTK) isolates supplementation into skim milk-egg yolk based diluent to maintain the quality of Merino ram spermatozoa.  Four ejaculates of two Merino rams were divided into two groups for the control group (P0): Merino ram semen was diluted in skimmed milk-egg yolk based diluent, and the treatment group (P1): Merino ram semen was diluted in skim milk-egg yolk based diluent contained crude PTK 1,597 mg/ml diluent. All diluted semen was equilibrated for 2 hours at 5 °C and filled into 0.25 mL French straws. The filled straws were placed on steel racks (Cooltop, Minitube) held in liquid nitrogen vapour for 10 minutes at –140 °C, immersed immediately in liquid nitrogen at –196 °C, and stored for 48 hours for  later assessment. Post-thawed semen samples were evaluated for spermatozoa motility, viability, and morphological abnormality. The results showed that the spermatozoa motility of fresh semen of Merino ram was 82.5 ± 2.89, which was qualified for freezing. The post-thawing spermatozoa motility, viability, and morphological abnormalities of Merino ram in the P1 group were 34.11 ± 3.26%, 38.00 ± 3.00%, and 12.89 ± 4.54%, respectively. It were higher (p <0.05) than the control group of 24.44 ± 2.9%, 26.67 ± 3.32%, and 21.11 ± 3.02%. It was concluded that the addition of crude PTK isolates of 1.597 mg/ml skim milk-egg yolk diluent improved the quality of post-thawed spermatozoa of Merino ram.

Abstract

This research was conducted in the teaching farm of the Faculty of Veterinary Medicine, Universitas Airlangga. The present study aimed to determine the effect of age, temperature, and humidity on bull semen quality which was processed into frozen semen. Three age groups of bulls (young 3-4 years, middle age 5-6 years, and old 7-8 years) were collected for the temperature and humidity of semen examination. Fresh semen was collected using an artificial vagina, followed by macroscopic and microscopic examination. In addition, post-thawing motility was also evaluated. The results showed that there was no effect of temperature and humidity during semen collection process. Fresh semen quality was affected by age. Moreover, the post-thawing motility of fresh semen of spermatozoa was lower than those of the fresh semen; however, it still qualifies for artificial insemination. It could be concluded that the semen of bulls at the Teaching Farm of Universitas Airlangga has good quality, and is suitable for Artificial Insemination.
