Mountain goats (Oreamnos americanus) are among the most culturally and economically important large mammal species in Alaska. Due to their low population growth rates and relatively high degree of sensitivity to natural and anthropogenic disturbance, resource management decisions must be carefully evaluated to ensure sustainable populations. In this study we combined data collected from 124 GPS...

This article offers information on the present status of goat populations and their productivity. The overview discusses number of goats in different parts of the world as well as the top countries having goats. The article also reviews the status of goat milk and meat production over the globe. In addition, breeding objectives and genetic improvement programs for milk and meat are discussed gi...

The survivability of caprine spermatozoa was compared in semen extenders prepared from the conventional egg-yolk citrate and goat-milk citrate. Motility was comparable in both sets of extenders during the first 24 hours post-extension when extended ejaculates were stored at either room temperature (28 O C) or refrigerator temperature (5 O C). Motility in goat milk citrate extenders at 5 O C was...

Altogether 562 sheep and goat blood serum samples were collected from livestock located in Konya, Burdur, and their environs in Turkey. The samples were tested for bluetongue virus antibodies by ELISA and serum neutralization test (SNT). Fifty-four (17.1%) out of 315 sheep serum samples from Konya and 1 (1.5%) out of 66 sheep serum samples from Burdur were detected as seropositive. Seventy-thre...

background: little is understood about the regulation of gene expression during early goat embryo development. this study investigated the expression profile of 19 genes, known to be critical for early embryo development in mouse and human, at five different stages of goat in vitro embryo development (oocyte, 8-16 cell, morula, day-7 blastocyst, and day 14 blastocyst). materials and methods: st...

The low number of embryos obtained from IVM-IVF-IVC of prepubertal goat oocytes could be due to an incomplete cytoplasmic maturation. Roscovitine (ROS) inhibits MPF and MAP kinase activity and maintains the oocyte at Germinal Vesicle (GV) stage. The aim of this study was to determine if meiotic activity is arrested in prepubertal goat oocytes cultured with 0, 12.5, 25, 50 and 100 microM of ROS ...

One hundred female Markhoz goats (42±5 kg) were used to investigate the ‘male effect’ on estrous synchronization and reproductive characteristics of female goat during the breeding season. This was carried out in three separate experiments. In the first experiment, forty female goats were used in 4 groups with different distance from the male goats (i.e. source of pheromone secretion); A1 (1 me...

This review focuses on the platform of recent advances in reproductive biotechnologies in sheep and goat. Here, we discuss some aspects of veterinary and biomedical importance in artificial insemination using sexed semen, in vitro/in vivo fertilization, interspecies in vitro fertilization, multiple ovulation and embryo transfer (MOET), somatic cell nuclear transfer and transgenic animal product...

Antibodies raised to pure canine renal renin were used to probe homology of renin from other species. Goat, rabbit, and mouse antibodies exhibited similar properties and were specific for renin as confirmed by immunodiffusion, immunoelectrophoresis, and selective inhibition of renin enzymatic activity. Goat antibody also inhibited the enzymatic activities of rat, hog, and bovine renin. Immunolo...

Nowadays, the quality of any food used for human consumption is, to a considerable extent, considered by its possible contribution to the maintenance or improvement of the consumer's health. In developed countries there is increasing interest in goat milk and its derivates, the quality of which is considered of special importance in the light of current tendencies favouring healthy eating. In p...
