Abstract

This study aimed to determine the influence of breed and type of extenders on frozen semen quality of cows at BIB Lembang. The experimental study was conducted in a Factorial Randomized Block Design (RBD) with two factors. The first factor was four cow breeds, i.e. Ongole Cross (PO), Brahman (BR), Simmental (SM) and Limousin (LM), and the second factor was two types of extender, i.e. Skim-Egg Yolk (SKT) and AndroMed® (AND), all repeated four times. The observed variables were percentage of spermatozoa motility and intact plasma membrane (IPM). All data obtained were analyzed using a general linear model (IBM SPSS ver. 23). The results demonstrated an interaction between breed and the type of diluent to motility. Breeds showed significantly different motility but non-significantly different intact plasma membrane (MPU) of semen. The type of diluent did not significantly affect motility and intact plasma membrane (MPU) of the frozen semen. The effect of the breed on BR motility was lower and significantly different from PO, LM and SM. The types of diluent did not significantly affect motility, MPU. The results showed that SKT was lower than AND, it was indicative effect of breed on intact plasma membrane (MPU) PO was lower than BR, LM and SM and the effect of the type of diluent on whole plasma membrane (MPU) AND is lower than SKT. It can be concluded that breed influences the motility of semen. The lowest motility reduction in frozen semen is Brahman cattle by using skim-egg yolk extender.

Abstract

The objective of the research was to determine the estrous profile of Etawah Crossbred goats after estrous synchronization with different methods. Eighteen does aged 12-24 month old were divided in three groups to receive estrous synchronization treatments (T1 = 14 days intravaginal implant of 60 mg of progesterone (MPA), T2 = two times injection of 5 mg PGF2α (lutalyse) in 11 days interval, and T3 = 10 days of intravaginal implant of 60 mg of progesterone (MPA) + injection of 5 mg PGF2α 48 hours before removal) with six replications. The parameters consisted of estrous behaviour, changes in size and colour of vulva, and duration of estrus when the number of superficial and keratin cells were dominating in the vaginal mucus cell. Data from estrous behaviour and score of vulvar colour was analyzed using Kurkal Wallis test, while onset of estrus, size of vulva slit and estrous duration was analyzed using ANOVA and Duncan test. The result showed that estrous behaviour and changes in color and size of vulva were not significantly different, but estrous duration was significantly different. Estrous duration in T1 (31.30 hour) and T2 (31.10 hour) was significantly longer than that of T3 (11.36 hour). It is concluded that different methods of estrus synchronization affected estrous quality equally but it affected the estrous duration differently based on vaginal mucus cells. Treatment implant vaginal sponge content progesterone for 14 days and double injection of PGF2α with 11-day interval given longest estrous duration.
