Abstract Genetic improvement of cattle around the globe has and will continue to be, an important driver animal agriculture sustainability because advances are permanent cumulative. There several reproductive molecular biotechnologies that can be used in genetic programs, their outcomes maximized when combined synergistically a structured breeding program with clear objective. One most recently...

Background Tree breeding is logistically complex and expensive, and breeders have long sought to use molecular markers to accelerate breeding. A candidate gene approach based on testing for association between the presence of DNA sequence variation in or near candidate genes, and phenotypic variation in a population has long been explored [1,2]. However, using candidate gene approach (QTLs) has...

BACKGROUND Rift Valley fever virus (RVFV) causes a viral zoonosis, with discontinuous epizootics and sporadic epidemics, essentially in East Africa. Infection with this virus causes severe illness and abortion in sheep, goats, and cattle as well as other domestic animals. Humans can also be exposed through close contact with infectious tissues or by bites from infected mosquitoes, primarily of ...

Congenital malformations resulting in late abortions and stillbirths affect the economic wellbeing of producers and the welfare of cattle in breeding programs. An extremely high incidence of stillbirths of "half-sized" calves of normal karyotype and uninflated lungs was diagnosed in the progeny of the Finnish Ayrshire (Bos taurus) bull--YN51. No other visible anatomical abnormalities were appar...

The article is dedicated to the complex stage in fate of Theodore Roosevelt, his life «Badlands» North Dakota, where he first appeared September 1883 hunt bison. Literally, we can say at glance fell love with these places. Fascinated by Roosevelt decided invest 14 thousand dollars purchase Chimney Butte Ranch, later renamed Maltese Cross Ranch. turned management lands over Sylwane Ferris and Bi...

The program "Nb_HetEx" estimates the effective number of breeders (N(b)) that produced the sampled progeny based on genotype counts contained in that sample. When the number of breeders is very small, there is an excess of heterozygotes in their progeny: the smaller the number of breeders, the larger the heterozygote excess. The Nb_HetEx program also estimates N(e) through the temporal method.

The purpose of this study was to analyze the success artificial insemination (AI) program in local cattle Kuala District, Langkat, Sumatera Utara Province. It conducted five villages: Bekiung, Beruam, Blankahan, Lau Kersik dan Raja Tengah. survey method employed study. respondents were selected by using purposive sampling method. There 41 breeders and 3 inseminators included as respondents. To ...
