This manuscript has come as a result of an efficient breeding program in Serbian cattle populations for some economically important traits. Genomic selection the last two decades been main challenge animal programs and genetics. Many SNP markers are used statistical analysis predicting accuracy values young animals without their performance. The new tendency allows genetic progress with reducin...

This study was designed to contribute the understanding of relationships between energy balance (EB) in early lactation [4 21 d milk (DIM)] and fertility traits [interval start luteal activity (SLA), interval first observed heat (FOH), conception artificial insemination (AI)], their associated with cow performance blood metabolites 4 150 DIM. Individual data (488 primiparous 1,020 multiparous l...

The review focuses on breeding practices aimed at improving resistance to diseases and health disorders that are associated with better efficiency, welfare longevity of cows. It is commonly known like mastitis, foot claw disorders, metabolic reproductive issues seriously violate dairy cows’ well-being. cause prevailing fertility deterioration has been the intensive selection merely based higher...

Financial, economic, and biological data collected from cow-calf producers who participated in the Illinois and Iowa Standardized Performance Analysis (SPA) programs were used in this study. Data used were collected for the 1996 through 1999 calendar years, with each herd within year representing one observation. This resulted in a final database of 225 observations (117 from Iowa and 108 from ...

Differences (disorders) of sex development are diverse conditions with variations in chromosomal, gonadal, and/or genital development. Fertility potential in this population is variable. Recent investigations into fertility potential in those previously thought to be infertile suggest that the majority may have fertility potential through experimental protocols. Fertility preservation may be mo...

This paper explores the causal link between income and fertility by analyzing women’s fertility response to the large and permanent income shock generated by a husband’s job displacement. I find that the shock reduces total fertility, suggesting that the causal effect of income on fertility is positive. A model that incorporates the time cost of children and assortative matching of spouses can ...

soil conservation is one of the most important regulative functions of natural ecosystems. this function is of high importance in taleghan watershed due to high erosion quantity and sediment accumulation in taleghan dam reservoir. soil loss reduction, sedimentation control and fertility conservation were considered as different aspects of soil conservation. effect of land use and vegetation cov...

The cluster of workstations (COW) is becoming an important platform for parallel processing applications. COWs offer the benefits of cost and accessibility over other platforms. In order to develop applications which exploit parallelism on a COW, a programming tool, programming language, distributed shared memory, or a parallelising compiler should be used. Each of these approaches is discussed...
