Utilization of cauda epididymis spermatozoa has been carried out because these can be used in artificial insemination or vitro fertilization. The purpose this study was to obtain information on the quality which produced from Bali cattle at different ages. samples came 31 slaughterhouses. Information and identification age based structure incisors. Observations were made variables motility, con...

This experiment was designed to study the effect of insulin like growth factor-I (IGF-I) on cryopreservation of Hariana bull semen. For this purpose, semen ejaculates were collected from four Hariana bulls using artificial vagina at biweekly interval. The semen samples which possess more than 70% initial progressive motility and above 500 million/mL spermatozoa concentration was subsequently su...

In this study, the formation of hydrogen peroxide (H2O2) by chilled goat spermatozoa was measured. Furthermore, the effects of dead spermatozoa on motility characteristics were studied. Fresh collected ejaculates from five Shami bucks were centrifuged and virtually all seminal plasma was removed. A part of the collected spermatozoa was killed by two ways: the first by repe...

In the present study, the impact of non-functional spermatozoa on the cryopreservation success of functional boar spermatozoa was evaluated. Fifteen sperm-rich ejaculate fractions collected from five fertile boars were frozen with different proportions of induced non-functional sperm (0--native semen sample-, 25, 50 and 75% non-functional spermatozoa). After thawing, the recovery of motile and ...

This study examined whether washing and preincubation of boar spermatozoa was necessary to achieve high in vitro penetration rates of pig oocytes. In experiment 1, diluted, sperm-rich fractions, stored for 24 h at 16 degrees C (stored diluted sperm) were used. After centrifugation once at 50 g for 3 min, the supernatant was concentrated at 1200 g for 3 min. The pellets were washed (1200 g for 3...

Lentiviruses (LV) are nononcogenic viruses, belonging to the Lentivirinae subfamily. The name comes from the Latin word “lenti”, meaning “slow”. According to the definition of B. Sigurdsson, they are causing infections in a limited number of hosts with a long incubation period (months and years) and progressive course, accompanied by damage in definite organs/tissues and a lethal outcome (Sigur...

The sensitivity of the agar gel immunodiffusion (AGID) test for the detection of antibody to caprine arthritis-encephalitis virus (CAEV) was investigated with CAEV or ovine progressive pneumonia virus (OPPV) as the source of antigen. A total of 218 goat serum specimens were tested for anti-CAEV antibody by AGID and immunoprecipitation of [35S]methionine-labeled CAEV. In comparison with that of ...

Small ruminant lentiviruses (SRLV) are members of the Retrovirus family comprising the closely related Visna/Maedi Virus (VMV) and the Caprine Arthritis-Encephalitis Virus (CAEV), which infect sheep and goats. Both infect cells of the monocyte/macrophage lineage and cause lifelong infections. Infection by VMV and CAEV can lead to Visna/Maedi (VM) and Caprine Arthritis-Encephalitis (CAE) respect...

Foot rot is a highly contagious and economically important disease of sheep and goats, caused predominantly by Dichelobacter nodosus. The current investigation was intended to analyse the genetic variation for resistance to caprine foot rot among two purebred native breeds of goats(Malabari and Attappady Black) and crossbred (Malabari crosses with Sannen, Alpine and Boer) goats in Kerala state,...

Participatory Epidemiology (PE) was applied on the Maasai rangeland of northern Tanzania to understand pastoralist’s perceptions of the clinical and epidemiological features of Contagious Caprine Pleuropneumonia (CCPP). The study was conducted during the period of April 2008 and caprine disease event was directed during the period of July 2006 to June 2007. Participatory methods such as Focus G...
