The Portuguese Serrana goat breed: a review

Breed Use and Crossbreeding in Goat Production

Association of milk traits with SSCP polymorphisms at the growth hormone gene in the Serrana goat

The present study suggests the existence of an association between milk production traits and genetic polymorphisms at the growth hormone (GH) gene in the Portuguese indigenous Serrana goat. The DNA from 229 animals of two ecotypes (Jarmelista and Ribatejano) was analysed by polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) technique revealing a high degree of genetic...

Follicular dynamics in Serrana goats.

Twenty-two Serrana goats were studied through two successive estrous cycles in order to characterize their follicular dynamics during the breeding season. The ovaries of the goats were scanned daily by real-time ultrasonography and all follicles >or=3mm were measured and classified. The data were classified by the number of follicular waves per goat to test the hypothesis that temporal and morp...

A review on goat sperm cryopreservation

The ability to cryopreserve spermatozoa from all of the domestic species is challenging. Even though all of the cells must endure similar physical stresses associated with the cryopreservation processes, sperm from the different species are very different in size, shape and lipid composition, all of which affect cryosurvival. Thus, when a cryopreservation protocol has been optimized for sperm o...

Genetic Diversity Analysis of the Gohilwari Breed of Indian Goat (Capra hircus) Using Microsatellite Markers

Problem statement: Gohilwari breed of goat is a multipurpose goat mainly for milk and meat purposes and best suited in its harsh climatic condition. This breed is inadequately characterized till now at DNA level. So the present study was undertaken for population genetic analysis at molecular level to exploit the breed for planning sustainable improvement, conservation and utilization, which su...
