This study was done to evaluate the efficiency of ultrasound-guided transvaginal follicular aspiration without hormonal pre-stimulation for collecting the oocytes of indigenous Thai beef cattle (Bos indicus), and to assess the vitrification method for their preservation. All animals between 2.5-12 years were categorized according to age (i.e. heifer, young cow, and old cow). A medium-sized follicle (φ 3-8 mm.) had the greatest distribution among the various size classes (p≤ 0.05), and the mean of oocytes collected from each group was not significantly different. Postthawed survival was 60.78, 53.70 and 57.50%, with a cleavage rate of 38.71, 37.93 and 39.13%, and …

The present study investigated the influence of four different commercial semen extenders used during theholding time and the use of seminal plasma as a thawing medium on the frozen-thawed (FT) boar semen quality.Sperm-rich fractions were collected from 11 boars and were divided into four groups according to the type of semenextender used during the holding time (A, B, C and D). The extended semen was cooled down and centrifuged. Thesperm pellets were diluted in lactose-egg yolk extender plus glycerol and Equex STM Paste. The semen were loadedinto 0.5 ml straws and frozen. Thawing was achieved by immersing the straws in …
