Ongole cattle in smallholder farms on Java, Indonesia, have been crossed with Limousin, which is not controlled repeatedly. The character of estrus affects the success Artificial Insemination. This study aimed to determine relationship between characters before double dose artificial insemination using frozen semen sexing. research was conducted Senggreng Village, Sumber Pucung District, Malang...

Comparison of a large series of sexed adult skeletal populations and a similar series of adult pre-industrial peoples shows that there is a regular and systematic bias in the sexing of adult skeletons. This bias, which is about 12% in favor of males, is due to the nature of secondary sex characteristics in bone. It should be corrected in skeletal series before demographic analysis is made of th...

Sexing and centrifugation of spermatozoa is one way to improve the quality spermatozoa. This study aimed obtain right time for sexing with Bovine Serum Albumin media on morphology X-Y in Simmental cattle. was carried out from October 2021 November at Laboratory Animal Reproduction Health Breeding Center Superior Livestock Forage, Sembawa. The design used this a completely randomized (CRD) 3 tre...

Although the mechanisms under which sex ratio is controlled in nature remain unknown, researchers have attempted to treat sperm in an effort to predetermine the sex of the offspring. The methods of sperm separation that have been repeatedly reported to isolate fractions rich in X- or Y-chromosome bearing sperm are serum albumin gradient swim-up and flow cytometry. However, the ability of the se...

M.A. Ahlering, F. Hailer, M.T. Roberts & C. Foley A simple and accurate method to sex savannah, forest and Asian elephants using noninvasive sampling techniques Molec. Ecology Resources 11 (2011) 831-834 Abstract. We report the development of a reliable and efficient method for molecular sexing of all extant elephant taxa. We developed primers that amplify two short Y-specific fragments (SRY1 a...

I draw on my own experiences as a straight feminist geographer to address questions regarding teaching sexualities in geography. First, I look at `sexing’ and `queering’ geography curricula, not only upper level undergraduate and graduate courses that lend themselves to discussions of sexualities, compulsory heterosexuality, and heterosexism, but also lower level undergraduate courses. Second, ...

Abstract Sexing weakly/criptically dimorphic birds requires invasive techniques or molecular analysis. Alternatively, sexing can be based upon morphometric analysis, which remains invaluable in remote field conditions such as Polar regions. Nevertheless, discriminatory power may affected by methodological issues hampering comparison between/within studies, e.g. considering alternative analytica...
