this study was undertaken to compare the efficiency of fresh and frozen-thawed buck semen on in vitro fertilization (ivf) of goat oocytes. cumulus oocytes complexes (cocs) were collected by aspiration of 2-6 mm diameter follicles, which were obtained from slaughterhouse. upon grading, only normal quality cocs were maturated in tcm-199 for 48 hours. the percentage of cocs reached to the m-ii sta...

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...

Mammalian seminal plasma contains among others, proteins called spermadhesins, which are the major proteins of boar and stallion seminal plasma. These proteins appear to be involved in capacitation and sperm-egg interaction. Previously, we reported the presence of a protein related to spermadhesins in goat seminal plasma. In the present study, we have further characterized this protein, and we ...

Low purification efficiency and incomplete characterization of male goat (buck) spermadhesins (Bdhs) prompted us to develop an effective system to produce recombinant Bdhs (rBdhs). Bdh-2 cDNA was inserted into a prokaryotic expression plasmid, pTrcHis TOPO. The pTrcHis-Bdh-2 system was constructed to produce a His(6) fusion protein in Escherichia coli Top10 cells. Recombinant clones were select...

The aim of this study was to define breeding goals and determine the suitable selection index in Rayeni cashmere goat using simulated data. To select animals for increased quantity of meat, milk and cashmere produced, body weight of the doe (BWD), milk weight (MW), cashmere weight (CW), weight of kids for sale (WK) and number of kids for sale per doe (NK) was used as selection criteria. Four se...

Two experiments were conducted to assess the effect of buck exposure to synchronize estrus in mature and pre-pubertal norgestomet-treated crossbred (criolloxdairy breeds) goats. In experiment 1, 100 mature goats (25 per group) under range conditions were either teased at 48 or 24h before Sincromate-B (SMB; 9 days treatment of 2mg norgestomet) implant withdrawal. A third group was exposed to buc...

Control of estrus is essential for the efficiency of any breeding program in farm animals, artificial insemination, hand mating and prediction of parturition dates. The present study is providing new evidence about determination of silent estrus in Damascus does. Since many D. does do not show any interest toward the male across seasons compared with spontaneous estrus detected by buck goat (BG...

BACKGROUND Cryptococcus spp. are saprophytic and opportunistic fungal pathogens that are known to cause severe disease in immunocompromised animals. In goats there are reports of clinical cryptococcal pneumonia and mastitis but not of meningitis. CASE PRESENTATION The following report describes a case of a five year old buck showing severe neurological signs, including paraplegia and strong p...
