Aims: To find out the percentage of live spermatozoa after diluting goat's liquid semen using an andromed extender plus sweet orange essential oil.
 Study Design: Randomized Block Design.
 Place and Duration Study: Sample: Galang, Deli Serdang Regency, Indonesia, between December 2022 January 2023.
 Methodology: The research procedure starts with preparation extender, collection ...

Goats are small ruminants that reared by the rural community for financial income and nutrition. This study was aimed to determine effect of vitamin C addition in tris–egg yolk extender on lifespan Sapera goat spermatozoa stored 5o C. Semen collected from 1.5 years old male goat. The ejaculates were diluted Tris-egg (T-EY) added with 0, 0.2, 0.3, 0.4 g C/mL T0, T1, T2, T3 groups, respectively. ...

The current study was conducted to biochemical attributes of Pantja Buck semen. For this purpose six mature healthy bucks were selected from the Goat Unit maintained at Department Livestock Production Management, College Veterinary and Animal Sciences, Pantnagar, Uttarakhand (India). All experimental kept under similar feeding management conditions. Semen collection done early morning by artifi...

Background: Pantja is a medium sized, dual purpose Tarai goat breed of Uttarakhand and adjacent area Uttar Pradesh. Due to the lack pure breeding buck uncontrolled cross breeding, population this reducing continuously. Therefore, for preservation dissemination breed, cryopreservation semen artificial insemination by using frozen thawed can play crucial role. Methods: Semen samples were collecte...

Sperm cryopreservation represents a useful tool in the management of reproduction in goat production. However, freezing and thawing produce physical and chemical stress on the sperm membrane that reduces their viability and fertilizing ability. In this study, firstly we evaluated the effects of reduced glutathione (GSH, 1 and 5mM) supplementation of the thawing extender on parameters of frozen-...

The purpose of the present study was to produce live offspring from in vitro fertilized goat embryos. Oocytes were collected from abattoir ovaries and kept in oocyte collection medium. Oocytes were washed 4-5 times with maturation medium containing medium-199 with 5 μg/ml FSH, 100 μg/ml LH, 1 μg/ml estradiol-17β, 50 μg/ml gentamycin, 10% inactivated estrus goat serum, and 3% BSA (fatty acid fre...

In all domestic species, acceptable pregnancy rates with frozen-thawed semen are only achievable with intrauterine insemination. Unlike the cow and the goat, the cervix of the ewe is a formidable barrier to penetration for transcervical intrauterine insemination not only due to the physical size of the canal and a narrow luminal diameter (even at estrus), but also due to it’s caudally facing, e...

The purpose of this study was to investigate the effects of semen collection into tubes containing extender supplemented with BSA on the cryosurvival of goat spermatozoa. Semen was collected from two goats into empty tubes or tubes containing 10 ml extender supplemented with 0, 0.1, 1, or 5% BSA, and the washed spermatozoa were frozen as pellets in egg yolk-trehalose extender with the addition ...

An artificial insemination (AI) program using cooled semen was evaluated over a 7-year period in Florida goats. The effect of the following variables on pregnancy rates was analysed: production system, year and season of AI, synchronisation treatment, bucks, AI technicians, semen deposition site, days in milk at AI, milk yield and parity. Animals were reared under field conditions on commercial...

Currently, the assessment of sperm function in a raw or processed semen sample is not able to reliably predict sperm ability to withstand freezing and thawing procedures and in vivo fertility and/or assisted reproductive biotechnologies (ART) outcome. The aim of the present study was to investigate which parameters among a battery of analyses could predict subsequent spermatozoa in vitro fertil...
